The best of both worlds


This is a fabulous opportunity to source your injection moulded products manufactured under the precision control of British engineering in Kent, with tooling made at Chinese prices from our own Sinclair & Rush factory in Changzhou (Jiangsu province).

This really is - 'the best of both worlds'.

In simple terms, injection moulding heats grains of plastic to a liquid then forces it under high pressure into a pressure resistant block containing the precision mould that shapes, cools and ejects the end product.

Of all of the stages in the injection moulding process, it is the tooling that dramatically affects the product cost. Up to about this time last year, Sinclair & Rush Ltd sourced both the tooling and the moulding from our factory in China, shipping the end product to customers.

Since acquiring Component Force last Easter, we now bring Chinese priced tooling to our own manufacturing skills and resources right here in Kent – quality local engineering at globally cost-effective prices.

What’s more, we are launching a special offer – well it’s a special customer relationship really … we will share the investment costs of your Injection Moulding Tooling.

This means that your tooling set up costs will start from just £995 instead of £3,000, £5,000 or even £10,000.

Injection Moulding – how it works:

Injection moulded parts are often the best choice for complex, high volume products that require tight tolerances. In fact, injection moulding is the most prevalent process for creating plastic parts ranging from house wares to toys. The process involves pouring liquid plastic into a mould and letting it cool until it takes the shape of the mould. At Sinclair & Rush, engineers will work with you to design a plastic injection moulded part with one of the lowest tooling costs in the industry.

1. Granules of plastic powder are poured or fed into a hopper which stores it until it is needed.

2. Heaters heat the injection tube around the thread.

3. Once the correct temperature for the task has been reached, the screw starts turning and the hopper feeds the plastic granules into it.

4. The ram then adds the pressure needed to force the now liquid plastic into the moulding tool.

5. The tool / mould accepts the liquid plastic as it is forced into the often intricate channels within it, shaping the product.

6. At the end of the process, the tool opens and the product is released.
