Cable overmolding design guide.

Ensure the thickness of the tpe overmolding is sufficient enough not to cause delamination. Rtv rubber should be 0 085 from surface and have a pocket depth of 0 080 for resilience and reliable shut off. Are you looking for some basic tips to get started or ways to improve your design. Less thickness for corners and edges ok.

Download our product selector guide. Design for a nominal 0 063 thickness of chem 860 over the flat surfaces. 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. I need a cable assembly that will survive specific chemicals acids and bases.

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. Use mechanical interlocks to reinforce the overmolding. Wall thickness in the range from 0 060 to 0 120 will ensure good bonding in most overmolding applications. Overmolding insert molding our basic guidelines for overmolding and insert molding include important design considerations to help improve part manufacturability enhance cosmetic appearance and reduce overall production time.

Part design and tooling. If the part requires the use of thick sections they should be cored out to minimize shrinkage problems and to reduce the part weight. 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. Guolan is professional custom manufacturer of electrical and electronic cable assemblies in small custom runs and large production quantities.

Offers control and data cables power cables. The purpose of this guide is to emphasize basic principles of overmolding. About this guide this guide will assist the process engineer part designer tool designer and toolmaker in the use of gls tpe compounds. My cable assembly will be plugged unplugged from an electrical source repeatedly and frequently.

My cable assembly will need to withstand a high amount of physical abuse and abrasion. Capabilities include molding hand wiring and engineering. Consider these helpful tips. The guide is based on over ten years of experience of gls chemists and engineers on overmolding tpes.
