Plastic welding

Plastic welding

From individual components to a single, robust whole: the endless possibilities of plastic welding at De Beer Plastics.

If you can’t do it the way it should be done, you’ll just have to do it the way you can.

‘If we can’t do it the way it should be done, we’ll do it the way we can’ is a well-known saying at De Beer Plastics, which clearly shows that we are always looking for ways to make things work. Plastic welding is one such technique that opens up many possibilities for manufacturing complex products.

Thanks to our extensive experience with various welding techniques, we are also able to produce the equipment required for welding the plastic components quickly and reliably, in parallel with the construction of the moulds.

Design freedom

Welding techniques offer designers greater design freedom when developing plastic products. Complex geometries and internal structures, which cannot be achieved with a single injection-moulded part, can be realised by distributing functions across two components.

This gives you greater freedom in terms of material selection, wall thicknesses and functionality. Furthermore, welding makes it easier to optimise products for manufacturability, cost and performance. The engineers at De Beer Plastics will help you bring your design to life.

Mirror welding

Mirror welding is a reliable technique in which thermoplastic injection-moulded parts are heated and pressed together in a controlled manner. This creates a homogeneous weld without the need for adhesives or fasteners. It enables products to be joined together in series production to form strong, leak-proof assemblies.

Using state-of-the-art mirror-moulding machines, De Beer Plastics creates joints with high mechanical strength and reproducibility for the automotive industry, amongst others.

Ultrasonic welding

Another technique offered by De Beer Plastics is ultrasonic welding. This is a fast and precise technique in which high-frequency vibrations fuse contact surfaces locally. In this way, we join technical plastic components permanently, without the need for additional materials or long cycle times.

This method is particularly suitable for complex and finely detailed injection-moulded parts, or for melting and forming special pins, which can be used to attach incompatible materials such as filter media or elastomers. The result is a strong, clean bond with a high degree of process reliability.

Guaranteed waterproof

A good welded joint between two plastic components can be pressure- and watertight. To ensure this, De Beer Plastics builds special test rigs on which products are tested for leaks using compressed air.

In the same structured manner as with our other ISO and IATF-certified production processes, the quality of the assembled parts is continuously monitored and guaranteed.
