Technology and production

Thermoplastic injection moulding

The thermoplastic granulate heated above the melting temperature is shaped into a liquid plastic mass which is then injected into an injection moulding tool under high pressure. The mass is then cooled down in the tool and finally the product is removed.

Two-component thermoplastic injection moulding (2C)

Two types of thermoplastic granulate are injected successively into the tool according to the same procedure as described in the thermoplastic injection. In this way, a product is obtained from two thermoplastics.

GIT (Gas Injection Technology) thermoplastic injection moulding

During the filling phase of the tool with a thermoplastic melt, a part of the product is filled with gas. In this way, we achieve a more rigid product construction that weighs less.

Manual assembly

By means of simple preparations we provide manual assembly, screw connections, “click” assembly, etc. of the product components that are injected. Manual installation is designed for smaller batches because the investment in automatic machines is not financially viable.

Automatic assembly

We assemble various injected products by means of dedicated machines with electric, hydraulic and pneumatic actuators. Automatic assembly is designed for high-end mass produced products where the investment into dedicated machines is required. By automation we are increasing the process quality assurance of the assembly line with sensor and control assemblies.

Ultrasonic welding

By using an ultrasonic machine, a part of the product is melted by applying friction and therefore two thermoplastic pieces or a metal piece can be joined together with a thermoplastic product.

Pad printing

Pad printing is the process of applying a 2D image to a 3D product. This is achieved by using an indirect offset printing method which includes a 2D image that with the matrix is applied to a 3D product via a silicone pad.

Robotic PUR foam application

Using a robot we can apply a thin PUR seal foam film to a thermoplastic product.

 

Production

INJECTION MOULDING

The injection workshop is equipped with the latest injection moulding machines for single and two component injection, GIT technology and metal or plastic component injection moulding. The injection machines have a closing force of 50 to 1,300 tons and injected product capacity ranging from 1g to 4,500g.

For the safe and quick manipulation of the injected products, all the injection machines are equipped with robots and feeding conveyors for the automatic removal of products from the injection tool. All injection moulding machines are also equipped with a central granulate drying and dosing system. In addition to using injection machines, we also perform simple automatic and manual installations.

ASSEMBLY

We perform demanding manual and automatic assembly using the so-called Poka Yoke Systems to provide 100% quality of the manufactured products. In addition to assembly, we also perform ultrasonic welding of plastic pieces, robotic PUR seal foam application and PU insulating foam injection as well as pad printing.

CONDITIONING

In a dedicated automatic chamber we can provide controlled moisture delivery or temperature stabilization for the products.
