Product Design

This service entails producing a working design of a prototype or concept. Once a design is accepted, production of the product begins.

Low cost tooling solutions Designed specifically for products that will not enjoy the benefit of high volumes, or where the cost of a full mould cannot be justified, our low cost solution fills a very necessary niche in the market. With this product the customer enjoys the benefit of injection moulding without the outlay required for mainstream tooling. Specifically the customer simply pays for cavity inserts and production of the article.
