Macromelt Molding

• What are the advantages of Macromelt Molding?

Low Pressure

• Injection pressure between 2 and 40 bar

• No damage of electronic parts

• Molds made of aluminium possible (low costs)


Macromelt Molding


Adhesive

• To manufacture parts (connector, PCBs...) which are water tight

• To obtain strain relief on cables

• Macromelt products based on natural raw materials – environmentally friendly


Macromelt Molding


Injection Molding

• Faster cycles than in casting applications

• Cycle times typically between 10 and 50 seconds

• Clean and simple to use process


Macromelt MoldingThe Materials – Macromelt OM 6..

• Standard color - amber or black

• Based on natural raw materials

• Three types for different service temperatures



Macromelt OM 652 / 657

• Operating temperature range: - 40 to + 100 °C

• Very good adhesion to different substrates

• UL 94: V0





• Good adhesion to different substrates

• UL 94: V0





• Adequat adhesion to different substrates

• UL 94: V0


Macromelt MoldingThe Materials – Macromelt OM 710


• Very good adhesion to PVC

• Plastic surface – Shore hardness D 40

• Very good resistance properties to various materials


Macromelt MoldingThe Materials – Colors

• With master batches you would get nearly every color you need

Properties


Macromelt MouldingTypical Project Procedure1. Collect the requirements

• Temperatures where he wants to use the parts

• Material(s) what we have to make tight, where we have to get adhesion to

• Resitance the customer needs for his product

(this 3 questions are the most important to find a possible adhesive)

2. Make spot test on the parts to get a first impression of the adhesion


Macromelt MouldingTypical Project Procedure3. Test procedure

• Make samples for the tests:

• For this you need a trial mould, where you can make samples in a proffesional way. Often you have to make the samples with different adhesives.

• The customer has to make all his tests, so that he will be sure that the parts fulfil all his requirements

• If the test are successfull go to the next step. If not, try it again. Try a new adhesive, try a new design.... There you will need all ideas (yours, of the customer, of the mouldmaker)


Macromelt MouldingTypical Project Procedure4. Production

• After a successfull test procedure you will know the right designand the right adhesive.

• With the design you will be able to calculate how many cavitiesare possible.

• With the production figures of the customer, it will be possible to find the right machine for him.

• After a successfull test procedure your customer will have the safety that all requirements are fulfiled.
