Ultrasonic welding & assembly

De Beer Beoplast develops and produces complete sub-assemblies. We are your 1-stop shop, from design and production to final assembly and packaging.

For assembly, we have modern facilities at our disposal, including machines for ultrasonic and mirror welding of plastic parts.  Other types of assembly are also offered in-house, if possible automatically, but also manually by well-trained assembly staff.

Large series can also be carried out effectively in cooperation with a nearby workshop for the disabled.

Where necessary, we also handle the purchase of components, seals and packaging material. Here we benefit from the various activities within the De Beer Group, which has a lot of experience in assembly and packaging.
