1Polyshot Hot Runner SystemsRevised 5/10/2006
The new Polyshot Heated Sprue Bushing product line was developed to address the precision injection molder’s need to process both engi-neered and commodity resins. Polyshot’s unique construction features a single heater, with a thermocouple sensing directly at the point of melt/freeze with a hard ened tool steel body.
The profi le wound single heater is encased in a removable, tapered stain less steel sleeve. All wires are routed through the top clamp plate to shield them from the molding process, which guarantees them long life.

General InformationThe Polyshot bushing length will be shorter at room temperature than when at operating temperature, due to thermal expansion. Heated length will be +.000 to -.010 from stated dimensions. More exact length re quire ments can easily be achieved by machining material off the con-tact surface of the collar face.
For a non-standard “A” length to be fi nished by Polyshot, spec i fy the special “A” length.
For a non-standard “A” length to be modifi ed in the fi eld by the cus-tomer, order the Polyshot Bushing with the “blank collar #109” in place of the standard collar.
The heaters in the Polyshot Bushing will operate at 208–240 single phase volts AC only.
Because the Polyshot Bushing controls temperature by sensing directly at the point of melt/freeze, the settings on the controller (Firebox) will be ap prox i mate ly 120 F° cooler than the nozzle on the mold ing ma- chine.
All dimensions are in inches. Metric Polyshot bushings are available upon re quest.
All Polyshot Heated Sprue Bushing drawings are available via FAX at no charge. Consult Polyshot for further in for ma tion.

This tip style uses a pinpoint gate design to allow the absolute min i mum gate vestige possible. In the “P” confi guration, the gate well area is ma chined directly into the mold cavity by the mold maker. In the “PR” con fi g u ra tion, a gate interface cap is threaded on to the end of the bushing, which allows for installation through a .7500" diameter reamed hole in the mold cavity. The “PR” con fi g u ra tion is used where a “ring” witness mark is acceptable. Both con fi g u ra tions feature a fi eld re place able tip, constructed with a very highly thermally con duc tive material.

The Conan bushing was spe cifi cal ly de signed to mold very small parts, using glass fi lled LCPs. It is used ex ten sive ly in the in jec tion molding of high pre ci sion electrical connectors. It will run at sub six second cycles with no drool ing, string ing or freeze-offs. It is most often used by gating into a runner. The gate vestige height will be ap prox i mate ly 1.5 times the gate diam-eter.

The Polyshot Microbushing was designed to be in-stalled in small molds such as those used in the Nissei HM7 injection molding machine and others. Its small size and fl ow path makes it very well suited to the very small shot sizes used in these applications.
Polyshot P-Microbushing is installed into a gate well detail machined in the “A” half of the mold by the mold maker. This bushing can also be fi tted with a PR Gate Interface Cap, to allow installation into a .625" diameter hole machined in the “A” half of the mold. The PR con-fi guration will leave a slight “ring” witness mark if gated directly into the part surface.

The Polyshot Multitip System is designed to allow precision injection molders additional fl exibility in the design, manufacture, and operation of their molds. The Multitip module can be used as a stand alone unit or it can be mated to a Polyshot Hot Runner Manifold to cre-ate 8, 16, 32, etc. cavity molds.
The Multitip module is a fully self-contained hot runner system consist-ing of a nozzle or manifold interface, externally heated fl ow passages, and two styles of fi eld replaceable tips. The use of a fully hardened distribution body allows 2, 3, 4, 6 or 8 tips to be integrated into the system. It is heated by internal cartridge heaters surrounding the entire distribution body. The Multitip operates on one zone of control and is monitored by an independent thermocouple located as close to the gate orifi ce as possible.
As with all other Polyshot Runnerless Systems, the Multitip was de-signed to facilitate applications where the ultimate in precision and reliability are required.

Single Module Sample Mold LayoutM U LT I T I P S Y S T E M S
The mold design shown above is a typical layout using a single Multitip
module. The mold features a standard “A” series style mold base with
the mold sand wiched between the top clamp plate and the “A” cavity
block.
The “A” cavity block should be constructed of hardened tool steel such
as A-2 or S-7 and drawn back to a hard ness of 48-50 R.C. This additional
heat treat draw affords the ad di tion al du ra bil i ty and resistance to crack-
ing that is re quired for this application. It is also rec om mend ed that the
top clamp plate be constructed of pre-hardened (P-20) tool steel to
maintain di men sion al integrity and resistance to deformation.
The Polyshot Firebox single zone temperature control system is avail-
able for precise tem per a ture control of molds employing the Multitip
System. It features auto tuning P.I.D. circuitry with a burst fi re relay,
allowing absolute state of the art control over the Multitip System. The
Multitip/Firebox com bi na tion allows easy one plug con nec tion when
mold disconnection is re quired.

Standard/Optional Layout InformationM U LT I T I P S Y S T E M S
The Multitip System is available in several different patterns. There
are fi ve probe layouts available (2–8 probes) with a “D” dimension of
2.0000" stan dard. Op tion al “D” di men sions up to 4.2800 diameter are
available at an additional cost.
Some commonly ordered optional “D” dimensions are 2.5000", 3.0000",
3.5000" and 4.0000". Op tion al Multitip confi gurations are usually deliv-
ered in 4–5 weeks.
Polyshot Corporation maintains in house testing facilities including a
Multitip test mold and in jec tion molding cell. This testing equipment is
available to prove out customer supplied resins for use in the Multitip
System.
28 Multitips Revised 5/10/2006
Manifold System ApplicationsM U LT I T I P S Y S T E M S
The Multitip System can be easily integrated into a Polyshot Manifold
System. This compatibility allows the molder to use the maximum
number of cav i ties in as small of an area as possible. One benefi t of the
Multitip sys tem is the reduced number of zones of control required to
operate the system. For ex am ple, a 64 probe (eight P-Multi-8 modules)
system can operate on as few as 10 zones of control.
All Multitip manifold applications require detailed drawings to be
pro vid ed for each ap pli ca tion. The layouts shown above are examples
of some of the different possible con fi g u ra tions in which the Multitip
Modules can be arrayed on a Polyshot Manifold system. All Multitip
modules used in the applications shown above constitute fully bal-
anced material fl ow systems. This feature allows each molded part to
fi ll at the same rate of pressure and speed, which results in excellent
shot to shot repeatability, and improved mold ed part quality.
The Polyshot Multitip Manifold System is available as a pre-engineered
fully assembled system ready to install into the mold. It is also avail-
able in a complete hot half system, including the Multitip system, top
clamp and manifold support plates, lo cat ing ring, wa ter line circuit and
all necessary mount ing holes, etc.

The Multitip System is furnished with pinpoint style probes in two
different lengths. The standard length probe is the “P” Series and the
extended length probe is the “PL” Series, for applications requiring ad-
ditional reach. All probes are threaded into the Multitip body and can
be easily replaced in the fi eld by the customer.
To calculate the diameters required for cavity machining, refer to
the “Diameter Calculations” chart above. This allows the customer to
specify either the standard 2.0000" “D” diameter or any other diameter
required, up to 4.2800".
All Multitip modules feature an integrated support pillar. This pillar fully
sup ports the mold cavity, and safely transfers the clamp and machine
nozzle force through the mold base assembly.
All dimensions that seal off the Multitip interface areas require precise
ma chin ing. The seat surfaces and bearing diameters of the module
should be machined within the tolerances specifi ed.

System Water Line Sample Layouts
The correct in stal la tion of water lines is critical to achieving the maxi-
mum per for mance of the Multitip system. The layouts shown above
incorporate water lines running between the molded part and the seal
sur fac es of the Multitip. These designs remove the max i mum amount
of heat from the mold cavity, allowing the cleanest gate and shortest
cycle time.
Under no circumstances should “water jacket” style cooling be the only
method used to cool the cavity block which houses the multitip.

The Polyshot Manifold System is a complete pre-engineered runnerless molding package. It is shipped fully assembled and tested ready to bolt on to the mold. It is also available as a “manifold only” unit for mold makers who prefer to construct their own hot half plates.
The Polyshot Manifold is heated with replaceable fl exible tubular heat-ers that are formed to the manifold grooves without the aid of special tools or fi xtures. They can be replaced in the fi eld by the customer if so required. Each nozzle is heated and controlled by its own heater and thermocouple. The thermocouple is positioned very close to the end of the nozzle for the ultimate in gate temperature control and shot to shot consistency.
Manifold fl ow balancing is achieved through the use of layered mani-fold construction (8 drops or greater) and in house vacuum brazing technology. This proprietary technology allows fl ow channels to be created with large sweeping arcs with gradually changing diameters. This process also allows the use of hardened tool steel for the manifold which assures long life with fi lled resins.

General InformationNozzle Align ment: Polyshot Runnerless Mold ing Systems are de signed to ac com mo date stress free ther mal ex pan sion. The cen ter of the man- i fold is fi xed in the mold by the noz zle in ter face en gaged into the top clamp plate, and a dowel pin which fi ts into the man i fold support plate. The noz zles are staged fi rmly into the man i fold sup port plate at two points. The fi rst point is the nozzle head, which fi ts into the man i fold sup port plate. The second is the end diameter, which fi ts into the back of the cavity block. As the man i fold heats up and expands, it is al lowed to slide across the top of the nozzle seats. As it ex pands, a secondary dowel pin en gag ing both the manifold and the manifold support plates control the fi nal manifold po si tion. When fully heated, the feed holes in the manifold are correctly aligned with the feed holes in the nozzles.
Nozzle Sealing: Sealing of the nozzles to the manifold is accomplished through both mechanical and ther mal means. The mechanical seal is accomplished by bolting each nozzle to the manifold using two socket head cap screws. The ther mal seal takes place as the system heats up. The thermal expansion across the nozzle and manifold thickness allows a predetermined amount of preload to occur on the nozzle seat. The combination of these two sealing meth ods pro duc es a reliable, trouble free seal.
Flow Channels: Polyshot fl ow channels allow a smooth material path from the molding machine nozzle to the gates, while re main ing free of hold up areas. The con struc tion of a Polyshot manifold features the use of specially designed turn plugs that allow the fl ow path to change both direction and diameter. Turn plugs are po si tioned in the manifold and ma chined while in place, then removed and polished by hand to achieve the nec es sary surface fi nish. They are then re in stalled into the man i fold and are retained with back up screws.

General Information
Thermal Expansion DrawingThermal Expansion: The drawing above shows the process of thermal expansion as the hot runner system heats up. All of the expansion cal-culations are taken into consideration by Polyshot’s engineers during the design of the system, thereby relieving the customer of that con-cern.
Electrical Requirements: All Polyshot systems operate at 208 to 240 VAC. All noz zles draw a maximum of 2 amps, and the max i mum draw of any single zone of a manifold is 15 amps. The total amp draw is de ter -mined by the number of noz zles required and the size of the manifold.

1 = This gate design may cause stringing if insufficient gate cooling is used with these materials.
2 = The pinpoint gate nozzle should be used with caution in glass/mineral filled applications.
A hardened tip insert is required. Please consult Polyshot.
Dimensions listed represent the starting gate diameter.
Note: This chart should be used as a guide only.
GF-Glass filled materials will wear out components quicker than non filled materials. In some applications,
it may be necessary to heat treat the manifold to a higher than normal hardness.
Flame retardant materials tend to have shorter than normal residence times. The result can be less than
satisfactory in molding small parts in some applications.

Pin point Noz zle styles af ford the absolute min i mum gate vestige pos si ble. They are used when it is nec es sary to gate directly into the part being mold ed. The pin-point nozzle fea tures a fi eld replaceable tip that can be easily changed by the customer if necessary. It per forms well when pro cess ing unfi lled resins. Hardened tip inserts are available as an option when it is nec es sary to mold fi lled resins.
When using the P-Series nozzle, all nec es sary tip clear- anc es are ma chined into the mold cav i ty by the cus- tom er. This meth od allows only a small pin point mark to be left on the part after molding.
The Pinpoint Nozzle is also available with a PR-Series gate interface cap. The gate interface cap has all nec- es sary tip clear anc es, etc., al ready ma chined into itself. The use of a PR-Series in ter face cap will leave a slight ‘ring’ witness mark on the mold ed part in addition to the pinpoint gate ves tige. The major fl ow diameter through the P, PL, or PR-075M is .2500", with .3750" op tion al.

Micromolding System HM7 Quick ChangeMicromolding System HM7 Quick Change
The Polyshot Micromolding System allows injection molders who have small mold-ing machines (like the Nissei HM7, etc.) to capture the full potential of the machine by the elimination of runners. This results in the use of the full potential of clamp pressure and injection capacity of the machine.
The Polyshot Micromolding System consists of a two-part bolt-in quick change “unit style” system which is installed onto the plates of the molding machine. The construc-tion of the system is hardened and ground stainless steel.
The fi xed (“A”) half of the system houses a Polyshot Multitip hot runner system, cooling circuitry with cavity insert face seals, insert alignment guide pins. Threaded holes allow a interchangeable mold cavity insert (customer provided) to be face mounted to it.
The movable (“B”) half of the system accepts a slide-in interchangeable mold cavity insert (customer provided). This portion of the system also includes cooling circuitry with cavity insert face seals that automatically seal upon cavity insertion. The design allows the use of stripper plate, ejector pin retainer plate to also fully seat upon cavity insertion.
As noted above, both the “A” and “B” halves of the system include predetermined locations for water to enter and exit the mold cavity inserts. There are two in and two out circuits for each half. This completely eliminates the need to connect any external water lines to the mold inserts.
The included Multitip System features hardened tool steel construction, (8) pinpoint gates and operates on one zone of control.

Firebox Single Zone Controller Systems
The Firebox Temperature Controller is designed to interface with the Polyshot Heated Sprue Bushing, Multitip System, and the Bank System. The Firebox is designed to stand up to the rigorous environment of the in jec tion molding room fl oor. It is a closed loop unit with provision for manual or “Open Loop” control.
The 3601 Firebox features an Auto-Tuning PID function that precisely match es the controllers electronic algorithms to the runnerless mold-ing system it is connected to. This is ac com plished by engaging the Auto-Tune function through the operator interface, which launches an electronic tuning cycle between the controller and the system its controlling. Upon com ple tion of this cycle, the Firebox rewrites its PID algorithms to precisely match the runnerless molding system it is con-trolling. When coupled with the controllers burst fi re relay system, the control of processing tem per a ture is excellent.

Circuit Breaker: To activate the Firebox, the rocker switch must be pushed to the “on”
position. This switch should be “off” whenever the unit is being plugged in or un-
plugged from a 208-240 volt single phase outlet.
Thermocouple Failure Protection: If the process was stable when the thermocouple
failed, the controller will transfer from auto to manual mode. The process will auto-
matically continue at the power level experienced in the two minutes prior to the
power failure, providing that the power level was less than 75%, and a power change
of less than 5% occurred. This will allow the system to continue functioning until a
thermocouple repair can be made. The percentage of power will be displayed in the
lower display. If process is not stable or the power level is greater than 75%, the out-
put is disabled.
Alarms: User defi ned temperatures that are the extremes on either side of the set
point at which the process can operate.
Alarm Low: Represents the low process alarm. The alarm sounds when the process
temperature strays too far below the set point.
Alarm High: Represents the high process alarm. The alarm sounds when the process
temperature strays too far above the set point.
Auto-Tune: Provides automatic tuning of the PID parameters to fi t the characteristics
of your par tic u lar thermal system. Successful completion of the auto-tune procedure
requires the process to cross the set point four times within eighty minutes after
auto-tune has started. Typical auto-tune pro ce dures last fi ve to ten minutes. During
auto-tune, the lower display alternately displays the set point temperature and the
prompt “At.” When auto-tune is complete, the lower display will continuously show
the set point temperature. Any change in set point while in auto-tune reinitiates the
auto-tune pro ce dure. Auto-tuning should be repeated after making any changes in
the molding process.
Temperature Units: The Firebox is capable of measuring temperature in both Celsius
and Fahrenheit. The default setting is Fahrenheit. To change the setting to Celsius,
con tact Polyshot for further in for ma tion.

Single Nozzle Valve Gate System
The Polyshot Single Nozzle Valve Gate System is designed for applications where zero vestige and cosmetic part surfaces are essential. This system is suitable for processing both fi lled and unfi lled engineering resins. The Single Nozzle Valve Gate system, which incorporates a cylindrical valve pin shutoff design, leaves a minimal gate vestige on the part surface that resembles an ejector pin mark. This unique design is also benefi cial to the moldmaker and processor as it eliminates the need to fi t a tapered shutoff pin.
The Polyshot Single Nozzle Valve Gate System consists of a fi ve-component, in-line, stacked assembly. This system uses the same proven valve gate technology found in our MS75VG Manifold Systems.
This system is designed to fi t into existing molds or into your new mold applications. Nozzle lengths are made custom to your application. All components are made from hardened tool steel. Installation of the Polyshot Single Nozzle Valve Gate only requires two air lines to be machined into the top clamp plate for operation of the opening and closing of the valve gate. The Polyshot Pneumatic Valve Gate Sequencer is available to control the timing of the valve gate. Refer to catalog page 84 for further information on the Polyshot Pneumatic Valve Gate Sequencer.
This system operates on two zones of control, which can be controlled with two of Polyshot’s 3601F Firebox Single Zone Controllers. Refer to the Temperature Controller section of the catalog for more information on the 3601F Firebox Controllers.
