BKB Precision: High Performance Plastics Machining

BKB Precision is a reliable partner in high performance plastics machining for more than 35 years. We process so-called high performance plastics or engineering plastics accurately to a precision of up to 3μm.

High-end plastic machining from start to finish 

Our versatility and years of experience with machining plastics make us a proper partner for constructing your concept up until the final product. Continuous upgrades to our machinery allow us to maintain the highest quality in professional CNC machining of plastics. Machining, shaping, assembling and/or cleaning plastics, we view the complexity of your design as a challenge!

State-of-the-art machinery

We boast state-of-the-art 24/7 machinery in our fully conditioned production hall. We have a wide range of CNC machines, ranging from three-axle milling to complex five-axle simultaneous milling or even 7-axle-milling and turning machines.


We are active in various industry sectors, such as hightech, semiconductor, medical, defence, food, aerospace, optical and chemicals.

    • 1x Okuma Multus B200 II

    Three axis and four axis milling

    We have various machines which can be used for three and five axis CNC machining. The choice for three axis or four axis milling depends on the complexity of the plastic product that is to be created. Generally, we can say that simple machining is done with three axis or four axis milling. We take of care of 3 and 4 axis machining with the following machines:

    • 5x Mazak VTC 300C
    • 1x Unisign Univers 4000
    • 1x Supermax 102
  • Plastics Machining

  • Professional machining of plastics

    Plastic machining in a prominent and innovative way is what we do at BKB Precision. BKB Precision is specialized in machining high-end plastics. We process high performance plastics accurately until the final product, for example through CNC machining (three and five-axis milling) or assembling. We make the almost impossible possible with machining plastics.

    High-end plastic machining from start to finish

    For over 35 years, BKB Precision has been an expert in the field of high-end plastic machining. Do you have a concept of plastic which must be realised with precision? We manufacture from prototypes up to medium sized series to meet your demands. Our versatility and years of experience with machining plastics make us a proper partner for constructing your concept up until the final product. The continuous upgrades to our equipment allow us to maintain the highest quality in professional machining of plastics.

    We work a lot with high-end technical plastics. Thanks to our expertise, we can machine your plastic the way you want it. We are also happy to provide you with a fitting advice in choosing the right plastic for your project.

  • Milling plastic

    Milling plastic is a machining technique where material is removed to create the correct finishing of the desired product. Milling at BKB Precision is computer-controlled, hence the name CNC milling. Our CNC milling services are executed with advanced machines that can be used for three-axis milling or the complex five-axis simultaneous milling.

    Our clients come from the following industries among others: Semicon, Medical, Defence, Optical, Engineering and Aerospace. BKB Precision is specialised in CNC machiningCNC lathing and in providing CNC milling services especially.

    Portal milling machines for large sheets

    We also offer possibilities to machine large (plastic) sheets with our portal milling machines. Both of our portal milling machines fall under the ‘extra large’ category and they can machine incredibly accurate, as you may expect of BKB Precision.

    CNC plastic milling up to 0.02mm accuracy over a length of over 6,000mm is possible! Partly thanks to the separate climate-controlled room which houses the machine (within our completely climate-controlled production hall), we can guarantee you a constant quality in our CNC milling services.

  • Compositing, cleaning, packaging, testing...

  • Compositing, cleaning, packaging, testing...

    BKB Precision strives to relieve you from your burdens and our added value in plastic assembly often benefits efficiency.

    Cleaning ISO class 7

    Cleaning parts and products is done with care; we work according to a strict protocol. In our cleanroom, plastic products are cleaned according to the Grade 4 norm. The room sizes 32m2 and has an ISO class 7 certification. If a higher clean grade is necessary, we can take care of this for you as well. We are happy to make any adjustments necessary to realize the desired form of plastic assembly.

    Cleanroom packaging

    In our cleanroom, plastic products are cleaned and packaged according to the class 7 norm. Specifications of the customer regarding the cleanroom packaging are taken into account as well. The cleanroom packaging of your components is daily work for us and is done for various companies. With years of experience in this regard, we are an excellent partner to help take care of it for you.

    Compositing plastic

    For compositing the various ‘assy’s’, we have the following possibilities available: mounting, gluing and/or welding. Because of these various possibilities, we are certainly able to assist you with your plastic assembly.

    Mounting plastic

    Mounting the components can also take place under cleanroom conditions if you so desire. All of the to be mounted components will be delivered clean, mounted in our cleanroom and packaged specifically for you.

    Gluing plastic

    Gluing plastic offers another wide range of possibilities. Gluing is possible in the following ways:

    • Ultra-violet gluing
    • Two-component gluelijmen
    • Solvents
    • Specifically prescribed glues
    • Etc.

    Welding plastic 

    Welding plastic is another process in plastic machining. This way of machining enables plastics to reconnect to each other. Various laser techniques exist. BKB Precision mostly makes use of hot gas welding (the welding of plastic with hot air). Any specific demands can be discussed by contacting us.
