INJECTION MOULDING DIVISION

The plastic injection moulding shop is specialized in production of thermoplastic parts for electrotechnical and consumer and automotive industry.

The mouldings are produced on injection moulding machines Arburg, Engel, Selex and Ponar in the parts weight range from 0.1 to 600 gms (PS). We operate the Selex injection moulding machines with the discriminator (evaluating device) monitoring the actual values of the injection moulding process and stopping the injection moulding machine if these actual values of parameters with respect to the moulding quality become unacceptable (QS).

The injection-moulding shop equipment has been extended with ENGEL Victory 50, an injection-moulding machine with the clamping force ranging from 280 to 6,000 kN; this enables highly efficient production operations due to ergonomic benefits of the tie-bar-less technology used in the clamping unit, such as minimum times for setting and exchanging of bulky moulds, possibility of utilisation of the whole surface of the clamping plate and easy access to the automatic unit. The high-accuracy injection process is achieved by the electric injection unit and due to absolute parallelism of the plates the process meets the strictest requirements for its accuracy.

We process a broad range of thermoplastic materials reaching from basic materials like PE and PP and PS over technical ones like PA, ABS, PC, POM, PBT to special ones like PPS and elastomers. All materials are processed both unfilled and filled, both in basic form and with additives (with a view to UV radiation, nonflammability, …). We carry out the dyeing procedure ourselves on the injection moulding machines according to the customers´ requirements.

Production of new moulds and maintenance of existing ones is ensured in the in-house tool shop under one roof.

You can get references from our customers ASCO, AEG Comp., Stabila, Brink, Ruoss, Fronius, Injecto Mold, Visteon, Dura, Batz and others.

We are looking forward to hearing from you both paying a visit to us and contacting us in relation to new projects as well as in the course of projects realization.
