For an engineer, the design of a new tool for injection moulding is regarded as a highly technical and complex task. Dealing with precision and tight dimensions, accuracy is crucial, and engineers are therefore generally aiming to be as precise and perfect as possible, like hitting a bull’s-eye in darts or other similar arrow sports.

Injection moulding is a popular method in product or component production. Despite the initial high set-up costs, it is a very cost-effective method of manufacturing. Almost every plastic part you can see and use is likely to have been produced in this way.

A mould, or the cavity into which the material will be poured, can be likened to a negative of a photograph. The design of the mould, or ‘tool’ as it is generally known, is very important, and engineers have to carefully consider a number of aspects, such as the product specification, materials to be used, and operational constraints. Once a model is constructed, it will need to be tested and reviewed before the manufacture of the tool can begin.

Over the 25 years Sanstec Design has been operating, our engineering capabilities have been utilised in the development of a variety of electro-mechanical products that have plastic injection moulded parts. This includes products from the automotive, consumer, medical, and pharmaceutical sectors. We don’t profess to be a perfect darts partner, but when it comes to tool design and engineering plastic parts, we can certainly promise to be precise and thorough.
