Injection molding plant

Fast and reliable production of plastic components

How do we perform injection?

Injection moulding is used primarily for the production of products from thermoplastic materials (polymers). The input material for production is a polymer in the form of granulate. Original or recycled granulates are used, mainly from the grinding of production waste. The granulates can be coloured in any way. We cooperate with leading granulate suppliers ready to deliver any material currently known. Most often PE, PP, PS, SB, SAN, ABS, PA, TPE, TPU are used.

What is the injection technique?

The manufacturing technique consists of plasticizing the material and injecting it into a mould usually equipped with a cooling system, in which the material cools and solidifies. After the mould is opened, the finished product is removed. Strumet's plastic injection moulding department is equipped with three Tederic injection moulding machines. These are modern and high-performance machines with clamping forces of 130, 350 and 700 tonnes. The maximum shot weight of the largest machine is almost 3400 g.

The operation of the injection moulding machines is supervised by experienced operators supported by technologists in optimizing the operating parameters of the machines.

Injection moulding shop – why is it worth using?

Injection moulding is the most popular technique for forming plastic elements. Irreplaceable in large-series and mass production. High efficiency combined with a small amount of waste that can be reused determine the effectiveness of the process. The low cost of producing a single part is unattainable for any other technique. Injection moulding makes it possible to produce finished elements and products of high quality and repeatability that do not require additional processing.

The injection moulding technique is also exceptionally environmentally friendly, because during forming there is no emission of any harmful substances. Plasticization of the material takes place by heating the granulate with electric heaters, which we partly power with energy from our own photovoltaic installation.

Advantages of producing plastics using injection molding technology

Production of even very complex shapes.
Exceptional speed - a single part takes only a few seconds.
No negative impact on the environment.
Repeatability of products with identical shapes.
High quality - of the surfaces of the products created.
