Troubleshooting injection moulding

A new review, "Troubleshooting injection moulding", looks at the different types of surface defects that can be identified in plastic parts and the best ways to solve these problems.

Injection moulding is one of the most commonly used processing methods for plastics materials.

Problems can occur at all stages in the injection moulding process.

The origins of these problems are often difficult to identify thanks to the complex interrelationship between the moulded part and the mould.

This review considers the factors that can affect the quality of moulded parts including the process, the machinery and the mould.

Common problems are considered so that they can be avoided when preparing components.

Successful troubleshooting should begin at the design stage not on the shop floor so that mistakes can be identified and remedied before they become critical.

A new review, "Troubleshooting injection moulding", looks at the different types of surface defects that can be identified in plastic parts and the best ways to solve these problems.

Flow charts are used to show solutions, as are case studies and a number of figures.

Surface quality is often critical, and this report is designed to help analyse these defects.

The review looks at a number of moulding defects including sink marks, streaks, gloss differences, weld line, jetting, the diesel effect, record grooves effect, stress cracks, incompletely filled parts, oversprayed parts, visible ejector marks, deformation, flaking, cold flow lines, entrapped air, dark spots and dull spots near the sprue.

This report will be of use to injection moulders, material manufacturers and all those involved in the industry.

The review is accompanied by around 400 abstracts from papers and books in the Rapra Polymer Library database, to facilitate further reading.

A subject index and a company index are included.

Arburg has been manufacturing injection moulding machines since 1954 and is considered one of the major global players.

This review is based on material drawn from their training courses and is the result of years of experience shared between many companies.

The Editor, Dr Vanessa Goodship, has years of experience in the injection moulding industry and is a Senior Research Fellow based at the Warwick Manufacturing Group in the Advanced Technology Centre at the University of Warwick.

"Troubleshooting injection moulding" retails at GBP 85 (plus postage and packaging) and is available from Rapra Technology.
