Mechanical production

RACOM also produces most of the mechanical parts for its products. After the expansion and modernization of our mechanical production in 2022, we have spare capacity in the new hall, which we offer for use by other companies. This gives them the unique opportunity to use our state-of-the-art equipment, for example, to machine aluminium alloys to the highest precision.

We are experts in the precision machining of aluminium, because for 15 years we have been producing microwave units with parts demanding extreme precision, at the limits of machining techniques. We machine aluminium castings, into which we mount our radio modems and microwaves. We make metal shells for the installation of our cellular routers. We can of course also do all other operations for the production of mechanical parts, including their design and construction.

Take advantage of the opportunity to have your mechanical parts manufactured in the same quality and precision as RACOM products. Our devices have MTBFs exceeding 100 years and are installed in more than 120 countries, from the poles to the equator.

CNC machining

Milling

We specialize in machining aluminum with high precision, but we can also machine other materials. We currently have three CNC milling machines from the Czech company Kovosvit. We have enough capacity in our machining shop, air-conditioned (± 3 ^oC) to allow us to achieve extreme precision, and we will be adding further CNC machines.

Other

Washing and drying

Most of the parts for our products need to be extremely clean, which is why we are equipped with several washing machines.

In addition to the degreasing washing machine, we also have two ultrasonic cleaners available. After the washing process, we dry all products in an industrial chamber dryer.

Cutting

Whether you supply us with the material or we provide it, it will probably need to be cut, and of course we are equipped for that.

Surface finishing

One of the few things RACOM does not do in-house is the surface treatment of our products. However, we have been cooperating with proven suppliers of these technologies for a long time. In cooperation we are able to provide powder coating (komaxit), or galvanic surface treatment (zinc coating, anodizing, etc.)

If you are interested, we are able to provide for comprehensive delivery and have your products varnished or otherwise surface treated.

Laser marking

We can mark or describe your parts or products with a laser from the Czech company Medicom.

Marking laser MEDICOM LASER SCRIPT LS-100

Marking field 160 × 160 mm

Assembly

If necessary, we can manually screw together or otherwise assemble your parts.

We also have an antistatic workplace where we assemble final products comprising PCBs and individual mechanical parts.
