Synergies of metal and plastic

Coming from the camera industry, PENTACON has a long-term experience in the fields of fine mechanics, the processing of metals or plastics with injection molding. With this know-how, we produce highest precision as a certified automotive system supplier and guarantee 100% fault-free delivery quality. To reach this aim, we continuously optimize our manufacturing processes and test with the help of self-developed optical and acoustic testing machines The complete process capability is mapped into a CAQ-system.

CNC turning

We turn metals such as aluminum, steel, high-grade steel or brass alloys as a CNC contract manufacturer. Our production depth reaches from small-batch, to medium-batch up to large-scale quantities processing parts of various geometry or complexity.

For several years, we have specialized in the turning of thin-walled parts, which feature tiny tolerances and require highest precision. Especially the turning of external threads and internal threads requires the long-term experience of a company rooted in the fine-mechanics and camera industry.

Swiss turning

At Swiss turning, the bar material is moved in axial direction through a headstock with a collet and a guide bushing. Unlike ordinary turning, the tooling is fixed. Originally invented for the watchmaking industry, this technology is widely used for long and slim parts. Depending on the arrangement of tools and guide bushing one can produce very precise and long parts, very often made of hard and robust material.

  • range of parts: Ø 3 bis 20 mm, length up to a max. 100 mm
  • material: broad range depending on appliance, focus on aluminum, brass, steel and high-grade steel
  • technologies: contour turning up to complex applications

Metal substitution and hybrid parts

Due to rising raw material prices, our customers increasingly change their production from using high-cost metals toward less costly plastics with similar or even better qualities. We counsel you in finding an efficient solution to lower your costs for materials. Ranging from exchanging single components to a re-design of your products (hybrid parts) up to the complete material exchange - we have developed a wide range of technologies and methods to save you costs and material weights. Usually, our customers come from the automotive industry where products tend to become increasingly lighter.

Profile-rolling of impact extruded parts

In cooperation with renowned technology partners, PENTACON developed various strategies to enhance CNC turning. Our approach is the profile rolling of HSS-steel. Our method is it to put a high pressure on the raw material and to roll the later profile in the pre-formed part. The advantages of this technology are:

  • no loss of material
  • high precision
  • cost-effective alternative
  • high sturdiness
  • very high repeat accuracy

Another approach is the impact extrusion of blanks toward their later geometry and an additional CNC turning afterward. The advantages are:

  • cost-effective alternative
  • less loss of material
  • faster working cycles
  • abrasive cutting or shearing
