Overmolding is an injection molding process that allows an additional layer of resin to be added to an existing molded part to provide a combination of characteristics that no single material can provide. The Overmolding Design Guide You Must Never Forget.
Guide To Designing A Custom Cable P Ii Blogs Teletec Electronics
The guide is based on over ten years of experience of GLS chemists and engineers on overmolding TPEs.
. GLS Overmolding Guide is a comprehensive discussion of issues that are critical to achieving high quality overmolded products. Connector type Cable type Length Overmolded style Male insert Female insert Free hanging receptacle PVC Black 1 m. Overmolding Design Considerations When designing cable assemblies engineers are using the overmolding process to provide strain or bend relief.
Table of Contents Introduction 1. Overmolding is an injection molding process where you cast a layer of resin usually a rubber-like plastic known as TPE over an already molded or machined material to give it properties it doesnt singlehandedly possess. This guide is a compilation of more than 25 years of experience in the de velopment design and processing of over molding TPEs based on contributions from a variety of Avient and industry sources.
Mm plastic 30968 sq. However its important to first create a prototype before applying the procedure to all your products. Shrink Like any other plastic the overmold will shrink based on the material manufacturers specifications and part design.
101mm from parting line. This guide is a compilation of over thirteen years of experience in the developmentdesign and processing of overmolding TPEsbased on contributions from a variety of GLS and industry sources. Low-pressure molding is ideal for protecting electronic components from hazardous environments.
Minimum part volume is 0025 cu. Overmolding is 90 percent mechanical and 10 percent cosmetic. Another advantage of overmolding is its flexibility in design.
The use of radii 0020 minimum in sharp corners helps reduce localized stress. There are numerous overmold applications for all of the wire harness and cable assembly products that Winchester manufactures and a limitless variety of interconnects. Wall thickness in the range from 0060 to 0120 will ensure good bonding in most overmolding applications.
Typically molded circular connectors have an internal premold which is the part of a molded connector. Cable overmolding of the back end of the connector at the junction point between the connection points and incoming multi-conductor cable provides a robust strain relief. A sleek transition from plug to cable can make your product look rugged and fit into the design of your overall product.
The heart of a properly designed and manufactured molded cable assembly is a fully encapsulated contact and wire termination point for strain relief and mechanical advantage. Mm silicone rubber Height may be limited if using a silicone as the overmold material and deeper parts are limited to a smaller outline. Overmolding Guide is a comprehensive discussion of issues that are critical to achieving high quality overmolded pr oducts.
Connectors and Power Cable Overmolding. Silicone Overmolding Design Guide. If the part requires the use of thick sections they should be cored out to minimize shrinkage problems and to reduce the part weight.
Up to 2032mm if the parting line can pass through the middle of the part. Factors to Keep in Mind When Considering Low-Pressure Molding Process Type of item to be molded. The purpose of this guide is to emphasize basic principles of overmolding.
Since more shrink is present with larger wall thicknesses its important to make sure that the overmold does not shrink away from the substrate. Overview The intent of this guide is to assist cable assembly designers in selecting readily available components when possible to minimize sample preproduction and production lead times. Straight HAUTS1104PAS1M HAUTS1104SAS1M Free hanging receptacle Right Angle HAUTS1104PAR1M HAUTS1104SAR1M Plug Straight HAUTS6104PAS1M HAUTS6104SAS1M Plug Right Angle HAUTS6104PAR1M HAUTS6104SAR1M Cable.
The advantage of overmolding is the potential for nearly limitless configurations and design elements improving environmental characteristics reliability and aesthetics. This includes grommets as part of the assembly for any points where an assembly needs to be installed through a housingopening and as a covering for the connector backshells to protect the. Encapsulate as much of the surface of the insert in rubber as possible with a minimum specified rubber thickness of 0020 in 051 mm.
Instead of assembling multiple parts the overmolding techniques can help to create a single part. This cable overmolding design guide will result in. Silicone overmolding is also known as rubber overmolding liquid silicone overmolding lsr overmolding insert overmolding multi-shot injection molding as a process that apply silicone rubber part - overmold onto the second part - substrate by compression molding transfer molding plastic.
It provides insights between cost and performance trade-offs for the most common design decisions faced by cable assembly designers in the Consumer and commercial markets. About this Guide This guide will assist the Process Engineer Part Designer Tool Designer and Toolmaker in the use of GLS TPE compounds. It can be used in a situation where there are complex assembly designs.
Check out this page for more on overmolding materials and processes. When designing rubber overmolded parts keep in mind the following design principles. This coverage helps to ensure maximum bonding and control flash formation.
