Cable Overmolding Design Guide

Cable overmolding design guide overmolding injection molding process for plastic parts.

Cable overmolding design guide.

My cable assembly will need to withstand a high amount of physical abuse and abrasion. Wall thickness in the range from 0 060 to 0 120 will ensure good bonding in most overmolding applications. 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.

Design for a nominal 0 063 thickness of chem 860 over the flat surfaces. The guide is based on over ten years of experience of gls chemists and engineers on overmolding tpes. Overmolding checklist i need a cable assembly with a long lifespan. Offers control and data cables power cables.

I need a cable assembly that will survive specific chemicals acids and bases. Overmolding design considerations when designing cable assemblies engineers are using the overmolding process to provide strain or bend relief. Ensure the thickness of the tpe overmolding is sufficient enough not to cause delamination. 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.

Less thickness for corners and edges ok. Are you looking for some basic tips to get started or ways to improve your design. Rtv rubber should be 0 085 from surface and have a pocket depth of 0 080 for resilience and reliable shut off. 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.

My cable assembly will be plugged unplugged from an electrical source repeatedly and frequently. Guolan is professional custom manufacturer of electrical and electronic cable assemblies in small custom runs and large production quantities. Download our product selector guide. 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.

Part design and tooling. 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. Use mechanical interlocks to reinforce the overmolding. Temp hum sensor is 0 095 from surface.
