Design for a nominal 0 063 thickness of chem 860 over the flat surfaces. Wall thickness in the range from 0 060 to 0 120 will ensure good bonding in most overmolding applications. This includes grommets as part of the assembly for any point s where an assembly needs to be installed through a housing opening and as a covering for the connector backshells to protect the. My cable assembly will be plugged unplugged from an electrical source repeatedly and frequently.

Use mechanical interlocks to reinforce the overmolding. The guide is based on over ten years of experience of gls chemists and engineers on overmolding tpes. Capabilities include molding hand wiring and engineering. Less thickness for corners and edges ok.

Are you looking for some basic tips to get started or ways to improve your design. The purpose of this guide is to emphasize basic principles of overmolding. Overmolding and insert molding are regularly used to manufacture multi material components for applications in industries such as medical and health care automotive and electronics. Rtv rubber should be 0 085 from surface and have a pocket depth of 0 080 for resilience and reliable shut off.

Overmolding design considerations when designing cable assemblies engineers are using the overmolding process to provide strain or bend relief. My cable assembly will need to withstand a high amount of physical abuse and abrasion. Ensure the thickness of the tpe overmolding is sufficient enough not to cause delamination. This white paper offers a primer on overmolding and insert molding and how they can be used both for prototyping during development and on demand production.
