How temperature influence the processing of TPE adhesion to ABS ？？

It is very common for TPE adhesion to ABS. On the premise of no problem for the equipment and mould. Temperature is the main infuential factor of injection molding processing.

some time ago, i have follow a client who look for TPE materials adhesion ABS. His product is a button(size:80 mm long,20 mm wide, 2~3mm Thickness, Main material is ABS) so he want some TPE materials to adhesion to this button in order to get better soft feeling.

First step, i take some button samples to our engineers for testing. according to the result, they provide me a TPE materials(hardness:50A,specific gravity:1.07) with Good mobility. I carried these sample to my client's factory for testing the sample.

second step: the processing of testing. First time, their engineer adjusted the temperature of machine to 190℃ but the result is very bad because of the product deformation. Second time,185℃，the result is better than first time. Third time, it is perfect.

Analysis summary: the reason of Product deformation is too much higher temperature during processing of overmolding and too fast speed of open mould. The concrete problem need a concrete analysis-GainShine TPE
