Polycarbonate Plastic Injection Moulding

We are leading UK manufacturers of many types of plastic injection moulding items at Stephens Plastics Mouldings. Our engineers will be pleased to provide you with information on the several types of plastics we provide and their compatibility for your product. One plastic material we use here for injection moulding is Polycarbonate.

Polycarbonate Injection Moulding

Polycarbonate plastic injection moulding is used in many industries. For instance, products such as lighting fixtures, optical lenses, parts for the aircraft, telecommunications, etc are made using the material. Furthermore, to obtain the exact colours and shades needed, it is important to achieve the correct wall thickness of ready parts. The higher thickness results in darker colours, and vice versa. Additionally, other important applications where polycarbonate plastic injection moulding is used, are those which involve outdoor uses. Where it is important to have UV radiation resistant items. Therefore, there are UV resistant polycarbonate grades which match the requirements for such uses.

The injection moulding is carried out by machines which have open nozzles with a large cross-section. The nozzles used are of the free flow type. In the event of leakage of the melted substance, the screw can be tightened to remove the pressure on the melt. The temperature during this injection moulding should be as high as possible. This is because it helps to obtain ready parts with very low inherent stress level. That is especially important when parts should be suited for superheated steam sterilisation.

Lexan is a brand name of Polycarbonate of which we injection mould.

High performance

The finest quality polycarbonate resins are used to manufacture parts which have high performance features. That is why polycarbonate parts are widely used in engineering, and they are often used to replace more conventional thermoplastics in an array of applications.

In polycarbonates, polymers are linked by means of carbonate group to form a long chain of molecules. The most common polycarbonate which also features extreme durability is bisphenol of which is mixed with carbonic acid. The material is obtained in a host of colours, as wall as in different varieties from opaque to transparent. Polycarbonates are distinguished by inherent strength and by rewarding physical properties, and although they are more expensive than similar materials which are cheaper and inferior in properties, they are preferred for polycarbonate plastic injection moulding.
