multi-component parts for innovative products and economically efficient production

Joint-ventures, mergers, fusions, blends, sym-bioses, alloys – all of them combinations of one form or another, and all of them testifying to the fact that it it is better to join forces than to go it alone. Combinations unite individual properties to form a stronger, more advanta-geous whole. Based on this principle, ENGEL combimelt technology embraces all the known methods of producing multi-component injec-tion moulded parts from plastics featuring dif-ferent properties and/or colours or from com-pletely different types of material.

The process at a glance

Multi-component injection mouldingProcesses for the combination of different material qualities and properties in one com-ponent.

In-mould assemblyThe purpose of this process is not to manu-facture single multicomponent parts but to mould and assemble individual components into structural and / or working units. Utilizing the specific properties of the individual com-ponents, it is possible to produce units with articulated parts or components with integrat-ed seals or gaskets.

Sequential mouldingThis process involves the sequential addition of different plastic components (materials and/or colours) and affords the product designer completely new possibilities. The most important application is the production of multi-colour parts (e.g. rear light covers) or control elements (keys and push-buttons with abrasion-resistant symbols). Combinations with translucently pigmented plastics are used for back-lit appli-cations (day and night design of car dashboard systems).

Overmoulding This process is used for providing equipment parts, such as handles and finger grips, with soft, non-slip coverings. This is done by overmoulding the thermoplastic parts with an elastomer.

Co-injection Also known as sandwich moulding, this process can be used for the production of multi-layer parts (usually three layers). In most cases, two different types of thermoplastic are in-jected into one another simultaneously, forming two outer skins and a core. The outer skins provide the product with a high-quality surface finish, while the core, which can be filled with reinforcing materials, improves the mechanical and heat-resisting properties of the part. The use of reclaim for the core considerably reduces costs. A foam core serves to reduce the weight of the part.

In-mould fitting of seals and gaskets. (rigid / flexible composites) The most important area of application for composite injection moulding is the in-mould fitting of seals and gaskets. Using the sequential moulding process, the ENGEL combimelt mul-ti-component injection moulding system can be used for the production of sealing elements from both thermosetting and thermoplastic elastomers.

Components with properties made to measureUsing selected combinations of thermoplastics, thermosets and elastomers, it is possible to manufacture components featuring a whole spectrum of made-to-measure properties, such as rigid/flexible composites with good damping cha-racteristics, parts with integrated sliding bearings or compo-nents in-mould assembled from transparent and non-trans-parent parts. Such options broaden the possible scope for creative design and versatility of function and application.

Component manufacturingBy selecting materials which do not adhere to one another, it is possible to produce articulated parts – hinge or knuckle joints, for example – ready-assembled in the mould, thus wa-iving the need for downstream assembly.

The achievable tensile strength and shear forces between the bonding surfaces are dependent on:- the material combination- the process and the process control system used- the part geometry

The time available for forming an intimate bond between the component materials is extremely short. This means that, irrespective of the anchoring mechanisms in the materials (interlocking action of the molecules or chemical reactions), free molecular movement must be present in the contact sur-faces.

Thus the important parameters here are the tempe-rature of the contact surfaces and the crystallization or glass transition temperatures of the materials to be joined together. Further factors influencing the strength of the bond are additives and fillers, and also specific conditions of use. It is possible to modify the adhesion behaviour of certain materials by means of compatibilizers. The table provides an overview of the achievable bond strengths of various material combinations. In the case of combinations of incompatible materials, i.e. materials which do not readily bond together, the connection must be effected mechanically, through a positive interlock, for example. In-mould assembly techniques utilize such in-compatibility for the production of articulated joints.

Rotary table system – with vertical rotary module

Mode of operationThe rotary table system is the one most frequently used with the Combimelt process. It is used both for the overmoulding and for the sequential moulding process. The moving platen of the machine is equipped with a rotary module. The sta-tionary mould half has two different mould cavities, while the moving mould half has two identical cavities.After the first injection operation in station 1, the rotary table turns through an angle of 180 degrees and transfers the pre-form to the second, larger cavity in the stationary mould half. The empty space between the preform and the cavity wall is now filled with the second material. The rotary table is rated for alternating rotation through an angle of ±180 degrees.

01 Ventilator housing for car air conditioning system

02 Used in conjunction with tiebarless clamping units, ENGEL rotary tables make optimal use of available space. Compared with tiebar clamping units, considerably larger moulds can be installed

03 The rotary table is a standard option which is available with every ENGEL injection moulding machine. A special rotary coupling permits the unrestricted supply of media (heating- cooling medium, electrical wiring, hydraulic oil) to the injection mould

01 02 03

A special rotary coupling permits the unrestricted supply of media to the injection mould. As the rotary table is an inte-gral part of the injection moulding machine, it can be used for several moulds. Rotary tables are available with up to 4 indexing positions.In this case, instead of oscillating, the rotary table rotates in one direction only.

Index plate system – for unlimited scope

Mode of operationWith the index plate system, the rotating and transfer func-tions are integrated in the mould. This system must be used in cases where the second component material is to be moulded onto both sides of the preform (moving mould half and fixed mould half). To this end, the preform, after being moulded in station 1, must be transferred to station 2, over-moulded on one side, rotated, and then overmoulded on the other.

01 Guiding/gliding element with main body in glass fibre- reinforced PA and integrally moulded glides in POM

02 This part is designed so that the second component material needs to be moulded onto both sides. This requires the rotation and transfer of the part into cavities that are differently formed for each side. The rotation and transfer operations are performed by the “index plate“

03 The “index plate” is normally an integral part of the mould. After each injection operation, the index plate moves out of the „parent” mould, rotates to-gether with the part and then moves back into the mould in readiness for the next injection operation. The system is limited in terms of size by the maxi-mum part weight that can be handled by the index plate

01 02 03

This is done by means of a so-called index plate in the injec-tion mould which removes the partially moulded part from the cavity, rotates it and replaces it. The drive of the index plate is integrated into the injection mould and adapted to the actual moulding requirement. The index plate system af-fords the greatest possible scope for combining two or more materials in a moulded part.

8 / 9

Transfer system – for small batches and special solutions

Mode of operationThis process is used primarily in cases of application where composite injection mouldings have to be combined with awkwardly sized or shaped inserts or where the use of a ro-tary table or index plate system would necessitate the use of a disproportio-nately large clamping unit. The transfer system is also used instead of the index plate system when the preform cannot be held by an index plate because of its geometry.

01 Gearbox casing with integrated sealing elements as an example of in-mould assembly on an injection moulding machine. A metal part is inserted by means of the transfer system during the production process

02 The transfer system makes practical use of the possibilities afforded by handling technology, e.g. for the insertion of metal parts or for transferring the moulded part from one position to another within the same mould or from one mould to another when working with two adjacent machines. By combining two machines each equipped with two injection units it is possible to produce four- component mouldings relatively easily. The transfer system may also be used in conjunction with ENGEL insert rotary-table machines (see the ENGEL insert brochure for more detailed information)

01 02

A handing robot is used for transferring the parts from cavity 1 to cavity 2. The transfer operation may take place either in the same mould, without any need for rotation, or between two adjacent injection moulding machines. Vertical rotary-table indexing machines with workpiece holding fixtures are also used in special cases.

Reversing slide system – with horizontal rotary module

Mode of operationAn ideal solution for the production of large – and especially for long – parts is the use of the large-capacity ENGEL duo (two platen) injection moulding machine. The machine is used in conjunction with a rotary module mounted on a sliding car-riage inside the clamping unit and two injection units mount-ed on the platens. For such applications, the combination of the horizontal rotary module and the cube-shaped central part of the injection mould makes better use of the available space between the tie-bars than is possible with a rotary ta-ble system.

01 Roof window for automobil

02 The horizontal rotary module carries the central part of a double-daylight (stack) mould. The combination of the horizontal rotary module and the cube-shaped central part of the injection mould permits optimum utilization of the available space between the tiebars. As the central part of the mould can revolve in steps of 90 degrees, it affords optimum access for insert-placing and parts-removal robots. As in the case of any standard double-daylight (stack) mould, the central part of the mould is kept in a central position, in relation to the platens, during the opening and closing movements of the clamping unit by means of a positively actuated hydraulic control

01 02

What is particularly advantageous about this system is that the two injection units are mounted on the two opposite plat-ens. This permits a simple design of the central, moving part of the mould and waives the need for a complicated hot run-ner system. This system is particularly suitable for large-area parts with integrally moulded seals or gaskets (e.g. car win-dow panes).

02 Photo above: injection mould for two-component in-mould slide method. Slide in closed position for injection station 1. Photo below: Slide in open position, permitting injection of second component

03 The use of the in-mould slide method for sequential multi-component injection moulding necessitates close collaboration between product designers and application engineers. The design of the moulded part must permit economically efficient use of the in-mould slide method notwithstanding its inherent complexity

Sliding split system – ENGEL combimelt without transfer of parts

Mode of operationWith the in-mould slide method, the cavity area of the sec-ond material is sealed off by hydraulically actuated slideable inserts or locking slides, ehich are opened after injection and initial cooling of the first material. In contrast with the other methods, injection of the second material is not done simul-taniously, but sequentially without opening the mould.

01 02 03

With no need to transfer parts, and with a less complex mould construction, this method may be economically viable for lower volume production, in spite of the longer cycle times generally associated with this method. Also, the more com-pact mould construction allows – in some cases – the use of smaller machines. The feasibility of the in-mould slide method is heavily dependent on part design.

01 Two-component screwcap (virgin material for outer skin, reclaim for core)

02 The ENGEL combimelt co-injection process produces a multilayer composite by feeding different streams of melt through the same nozzle. The injection mould does not normally differ from a standard type of injection mould. It is not equipped with rotary modules.

Co-injection – for sandwich and multilayer parts

Mode of operationThe co-injection process is used – in cases where multilayer parts are a possible alternative – either for reasons of cost (use of reclaim as core material) or for the sake of functional-ity (internal strength combined with high-quality surface fin-ish). For this application, ENGEL offers an equipment mod-ule for mounting on an injection moulding machine equipped with a second, vertically arranged injection unit. This module consists of a special co-injection nozzle which connects the two injection units.

0202 02

The nozzle feeds the melt streams via forced feed mecha-nisms in such a way that a defined partial filling of the mould cavity takes place with the „skin material” prior to injection of the core material via the same gating system. Thus one material is injected into the other. The already solidified outer layers of the skin material cannot be displaced and thus com-pletely enclose the core material.

Injection unit in “V” arrangement.Vertical injection units (“V” arrangement) are mounted above the stationary platen on a moving carriage. When the mould has to be changed, the vertical injection unit can be pushed back in the direction of the horizontal injection unit. This de-sign feature also permits easy and exact centring of the injec-tion nozzle in relation to the gate.

machines featuring combined horizontal and vertical injec-tion units can be readily converted for co-injection. To this end, the rails for the moving carriage are extended towards the horizontal unit, permitting connection of the two units by means of the special co-injection nozzle. This co-injection facility has proved particularly ideal for use with small and medium-sized machines.

“Piggyback” injection unit.The “piggyback” injection unit (i.e. second injection unit positioned above the main injection unit) constitutes a space-saving solution for an automated combimelt production machine with a handling robot mounted on the stationary platen. The second unit is positioned at an angle above the main unit. Both injection units move in parallel, ensuring a constant distance between nozzles regardless of their depth of insertion.

The upper injection unit is equipped with an additional contact pressure unit which permits independent nozzle retraction or nozzle insertion to different depths. The “piggyback” arrangement of the injection units within the ENGEL combimelt range of machines is based on a standardized distance between the nozzles. Non-standard versions are also available – please inquire.

ENGEL e-motion combiall-electric multicomponent machine

ENGEL e-victory combi tiebarless clamping unit, servo-driven injection units

ENGEL e-motion combi: the complete systemENGEL offers all-electric machines for multicomponent injec-tion moulding with clamp forces ranging from 1000 kN to 2800 kN. Both the clamping units and the injection units are identical to those of the ENGEL e-motion series (see special ENGEL e-motion brochure). What is completely new about this series of all-electric multicomponent injection moulding machines is that it is now possible to equip them with as many as three servo-driven injection units. Available in addition to these injection unit combinations are high-performance, elec-trically driven rotary tables and actuating systems for electri-cally operated mould functions. Therefore the specific advan-tages of the all-electric injection moulding machine can now be fully utilized for multicomponent injection moulding.

Multicomponent injection moulding:flexibility combined with precisionThe ENGEL e-victory combi series unites the advantages of the clamping units of the ENGEL victory series and the perform-ance features of the all-electric injection units of the ENGEL e-motion series. The possible injection unit combinations are identical to those of the all-electric multicomponent machines. The range of models covers the full small to medium-size ma-chine range from 280 kN to 3000 kN.

Available for the full ENGEL e-victory combi series is the comprehensive range of modules from the ENGEL victory machine system for application-related equipping and ad-aptation of the clamping units. These include, for example, extra-large platens, special platens and hydraulic core pull mechanisms. Thanks to the large scope of standard options, the ENGEL e-victory combi represents a perfect combination of the highest precision and efficiency on both the injection and the clamping side of the machine, and not least through the tiebarless clamping system, which not only makes for a considerable reduction in set-up times but also facilitates the installation and operation of automation equipment.

Possible combinations:The second injection unit can be optimally arranged to suit the actual application: - Piggyback arrangement (W)- Vertical arrangement (V)- Horizontal arrangement (L)

Tried and trusted machine controls geared to handle new demands

Basic functions- Switch on, - User identification, - USB interface

Settings: Clear-cut control logicThe control logic for the machine and robot support simple programming of an individual cycle sequence without spe-cial programming skills. The cycle sequence for the injection moulding process is subdivided into separate basic sequenc-es. These basic sequences – closing, injection and open-ing – along with the additional subsequences are mapped to characteristic function icons.

“Function library“ for easier programmingProgramming modules can be compiled from a comprehen-sive “function library“. Sequences are compiled in the Se-quence Editor by inserting or removing functions. “Drag and Drop“ gives users the ability to select functions from a menu and integrate them with the sequence for serial and parallel execution.

Dialog-based customization supportedTo change a parameter, users simply press the correspond-ing dialog box on the touchscreen and change the setting (e.g. for clamping force, closing or opening speed etc.). A plausibility check occurs after saving the modified data set to prevent incorrect settings.

ENGEL duo combi MA machine concept offering optimum versatilityThe machine concept of the ENGEL duo combi m (m stand for “movable”) is based on the enormous application potential afforded by the two platens of the ENGEL duo clamping unit. Both platens are combined with a horizontal injection unit. The clamping unit may be equipped either with a rotary table or with a rotary module for the injection moulds. Thus the machine is ideal for the production of large-area, two-component parts or for use with double-daylight moulds.

Horizontal rotary table with integrated lead-through coupling for lying media to the central plate of the injection mould

As alternative to the horizontal rotary table can be equipped the hines with a central mould mother board for floor forms. Thus two forms can be synchronously operated

ENGEL duo combi HH with two or more parallel injection units

ENGEL combimelt machines with parallel injection unitsare used for a diversity of applications. One of the principle applications is the production of multicolour rear light covers and other multi-component parts. The machines used are primarily of the large-capacity type, equipped with up to four paral-lel injection units of varying size.

When extremely large parts have to be moulded:For the injection moulding of extremely large parts, two (or three) injection units are combined via a common nozzle system. When combining three injection units, the parallel arrangement must be waived, due to lack of space, in favour of an angled arrangement.

Rotary tables: universal, service-proved, efficient

ENGEL rotary tables- ENGEL rotary tables are available in a range of diameters from 600 mm to 2000 mm. Other (special) sizes are also available – please enquire- Rotary table drives are generally hydraulic- ENGEL rotary tables are particularly fast and efficient: > Indexing speed of less than 1 second for 180 degree turn of 600 mm dia. table > Approx. 2 seconds for 180 degree turn of 1400 mm dia. table.- Negligible height of max. 135 cm. This means that any mould height compensation by exending the length of the machine frame is necessary only in very special cases

- All rotary tables have provision for the fitting of lead- through couplings for the media (including multi-circuit heating-cooling water or oil)- All rotary tables are available for two-, three- or four-station indexing operation, with either reversing or full rotation- All rotary tables feature an electronic rotation angle control for absolutely exact indexing

Two-station rotary table with provision for distribution of the media from the central lead-through coupling to the connection points located on the outside of the table

Special solutions for special projects

For special applications, the machine system of the “ENGEL duo combi m” can be modularly expanded with horizontally opposed injection units.

Additional injection units in “piggyback” arrangement and/or additional lateral injection units in “L” arrangement have al-ready been designed and are now in service.

For special projects are special models of multicomponent-machines with special unit combinations available on request. In the picture you can see a machine in “L” configuration with two equally sized injection units (usually the volume of the second component is less than the first)
