Ceetak has launched a new injection moulding service, designed to help customers reduce the unit costs of high volume component parts.
Ceetak has launched a new injection moulding service, designed to help customers reduce the unit costs of high volume component parts, while significantly improving both quality and, in many applications, delivery times.
The new service is based on a proven two-shot injection moulding process that has previously been widely used for the manufacture of products to give a pattern or textured feel where two coloured plastics or TPE (thermoplastic elastomers) rubber compounds need to be combined into a single part.
To date, however, limitations in mould and process technology have restricted application to low value, relatively low quality components, such as toothbrush handles, automotive gear shift knobs and screw driver handles.
To overcome these limitations, Ceetak has worked closely with injection moulding machine suppliers and mould tool designers, to improve both mould tolerances and the level of control over process conditions.
As the company's Sales and Marketing Manager, Bob Parker, explains: "This has taken time to perfect but has led to a significant increase in the quality with which we can produce two part components in a single moulding operation; perhaps as importantly, we can now do this consistently in high volumes but with extremely competitive prices.
This means that we can, for example, re-engineer replacement parts for products such as pneumatic valves that can be up to eight times less expensive, at identical standards of quality and often with better physical or mechanical properties".
The two part mouldings available through the new Ceetak service can be manufactured from most forms of thermoplastics and thermoplastic elastomer compounds and are produced in such a way that tough molecular bonds are formed between materials.
This ensures long term component reliability, while the potential to combine materials enables a variety of different performance characteristics to be built into each part.
