The production techniques for individual plastic enclosures
CNC milling/bending/welding

In the manufacturing process of enclosures or parts we rely on modern methods and technologies in order to produce your customized product with the utmost efficiency.

With the help of CNC milling technology, we are able to quickly produce small series without additional tooling costs. You have the choice between ABS and PS plates with a thickness of 2 to 10mm. After milling with the CNC technique, the individual parts are faceted and bended. In the next step bending cuts are milled. For this purpose, the CNC technology is used again. This results in no tooling costs in this step. When all parts of an enclosure have gone through the mentioned steps, they are assembled into a finished plastic enclosure and chemically welded.
Thanks to chemical welding, the connections between the individual parts are dust and splash-proof according to protection class IP64.


Individual membrane keyboards or front foils can bring the design of your plastic enclosure to perfection.
If you want your plastic enclosure to be the cover to electronically controlled devices, we can use panels and membrane keyboards for the information input.

Individual membrane keyboards and touchscreens
Membrane keyboards and touch screens are developed and produced according to customer requirements and can be integrated in plastic or aluminum enclosures. The production of base plates made of aluminum and stainless steel, their addition with mechanical inserts and the integration with a membrane keyboard are also part of our core competencies.

Aluminum enclosures
In addition to our plastic enclosures, we offer enclosures made of aluminum, the surface of which can be polished, anodized, painted or powder-coated.


KT Kunststofftechnik has the option to make 3D prints. In the FDM process – the fused deposition modeling – we print prototypes and complex, free-formed components of an enclosure. The materials ABS and ASA are used for this process. Models and components of various shapes and sizes can be manufactured in one piece without further intervention. Tool change and transformations are no longer required.


The combination of CNC milling/bending/welding and 3D printing makes it possible to compensate the disadvantages of each method.
The restrictions of the shaping and design of the milling/bending/welding process are abrogated by the 3D printing.
The complex enclosure parts of the 3D printing can then be welded together again with the plate parts of the CNC milling/bending/welding process. The large panel parts are manufactured using the more cost-effective CNC milling/bending/welding process and then assembled to a finished enclosure with the 3D printing variety.


The CNC milling/bending/welding technique allows us to customize your enclosures.
Thus, e.g. desired push outs, thread inserts and domes are taken into account during milling.
Push outs serve as preparation for a possible later breakthrough for e.g. cables without damaging the material.
Thread inserts have the advantage that you can start immediately with the assembly of your plastic enclosure and no further processing of the enclosure is necessary.
Welded domes are used e.g. as a spacer and thus prepare your assembly as well.
If your plastic enclosure requires a door, we are able to weld hinge pins into the enclosure.


If you want a visually appealing surface to your liking or for personalization, there is the option of refinement.
With the help of laser inscription, your plastic enclosures can be refined in one color. The laser marking is abrasion-resistant, precise and can be applied to a finished enclosure. It gives a strong contrast to bright plastics.
With the screen printing you can bring symbols, logos or text in several colors on your enclosure. The screen print is conditionally resistant to abrasion.
Another possibility for an individual style of your enclosure is the varnish. Here, you enjoy color freedom in matt or glossy and it gives your case UV stability.
