Needing help!

I have currently been tasked with adding some sort of “pusher” to push a plastic cover in our car body. I am needing an idea on something I can set the push force too. Since it’s plastic going in to metal it could be broken if too much force is applied. Any ideas?

Assuming you've done some data gathering for your process development and you know the magnitude of force required for part assembly and breakage. And material strength property variations and part tolerance ranges that will affect both.

idea1: a mechanical press assembly assist device of some sort that uses well-designed and calibrated spring arrangement for precise force application and travel is limited by hard stops

idea2: a pneumatic actuator device with flow controls, motion limits, and well-regulated air pressure

Thanks for the response. I think I will regulate a cylinder down enough to achieve the force I need for now as a trial.

You can consider using pneumatic, hydraulic, or electric actuators, combined with a sensor control system to precisely control the thrust and prevent plastic rupture.

electro-hydraulic or electro-mechanical are your options. depending on you load, space, budget, etc.
