Plastic Injection Moulding Processes for Your Production

Over 20 Proven Processes for More Efficiency

With ENGEL’s injection moulding processes, you can produce parts precisely so that no reworking is necessary. Whether you want a transparent or multicoloured part surface or want to enhance the part with patterns and engravings. The combination of technologies enables you to design products with high mechanical properties and attractive surfaces at the same time. With the appropriate transparency, sensors can be placed optimally protected behind cover panels. We always find the right injection moulding process for you.

Your Advantages With Our Injection Moulding Processes
Complete production cell from a single source for increased part quality
Image shows injection moulding production cell by ENGEL

At ENGEL, you receive a production cell that is ready to use: from the injection moulding machine, robot and conveyor systems to peripheral equipment. Immediately after machine and mould acceptance testing, you start production with the selected process. You can rely on highest part quality, stable injection moulding processes and high productivity.

Variety of materials can be used

With our injection moulding machines you can process thermoplastics and thermoplastic elastomers as well as thermosets. A wide range of applications is possible. Each manufactured part has different production requirements. Our experts determine which technology is suitable and choose one of our over 20 proven processes. Transparent materials, for example, can be manufactured into precise optical lenses using injection compression. We make use of the full performance spectrum of materials in your application.

Optimal settings thanks to innovative software solutions

We use innovative software solutions to optimise the injection moulding of your part. Assistance systems ensure greater weight consistency, optimum mould temperature control and important setting values - such as clamping force - are automatically suggested by the machine control unit. In more challenging injection moulding processes, various data must be monitored. Our software solutions precisely show those parameters with deviations.

User support for stable production processes

The application engineering team does not look at the challenges of injection moulding individually, but as part of the overall process. Our experts perform trials and afterwards ensure the ideal machine design for your process. We support you with the production of the first parts and then optimise the production process. The goal: an efficient, stable and cost-effective manufacturing solution.
