Why Machined Parts?

Extensive experience

Ensinger Machined Parts is at the forefront of engineering plastics. With more than 50 years of experience, we have established our reputation in the demanding field of engineering plastic components, supplying some of the biggest names in the aerospace, medical, automotive, food, printing, and oil and gas industries. 

Our team of skilled technical application engineers are on hand to support our customers where aid is needed, offering constructive advice, innovative solutions and material selection for a particular application. 

Knowledge transfer

Within the close bonds of the Ensinger Group, the knowledge transfer helps us find each customer the optimal solution. We will be pleased to support you in the selection of materials and throughout the design process of complex components.


Our workforce represents our single biggest potential. We lay the foundations for the future of our company by providing our own training programmes and apprenticeship schemes. As in any successful team, the right mix of older, more experienced staff members and younger colleagues proves successful.

Ask. Think. Succeed.

The Ensinger corporate philosophy is shared as a success formula by the Machined Parts Division too, because we focus consistently on finding the optimum technical and economical solution for our customers.

Vast portfolio of high performance plastics

In addition to the machining services we offer, our customers also benefit from the pooled expertise of the entire Ensinger group, as well as access to a stockholding of over 100 high performance and engineering plastics, which meet even the most demanding requirements. 


Batch tracing for our products is a matter of importance. Quality assurance, biocompatibility testing, ultrasound, seamless traceability and works test certificates are examples of our exemplary quality control processes. Furthermore, a high percentage of the semi-finished products we process are from Ensinger’s own extrusion department, highlighting another clear quality advantage.

Quality management complete with documentation and batch tracing

To allow our part quality to be assessed in accordance with current standards, we attach maximum importance to the equipment fit-out of our Quality Department. Armed with everything from tactile coordinate measuring machines to optical measuring devices, surface gauges, a contourograph and a large selection of other measuring instruments, we are ideally equipped to meet every conceivable measurement-related challenge.

In-process recording and documentation are part of our day-to-day work. In addition to the standard audits, we are regularly audited and inspected by customers.

Large network of machines to secure delivery

  • Multi-axis machining
  • CNC turning
  • CNC milling
  • Tool management


  • Delivery of completely assembled systems and modules
  • Assembly and function testing
  • Deburring of parts, optionally with your required surface finish
  • Engraving, laser inscription (e.g. batch tracing)


Aircraft and aerospace plastic materials

As requested by our customers, we have checked and qualified a large share of our materials against required specifications. We can qualify additional materials on request. Due to the special requirements of the aerospace industry, Ensinger takes on responsibility for: raw materials receipt inspections, raw materials specifications, composition specifications for individual articles, final inspections, issuing of inspection certificates, and much more.

Plastics for food technology

Attaining food grade plastic compliant with the stringent demands of FDA and European Food Contact regulations, is nowadays a key requirement for thermoplastics machining operators in this industry. Ensinger offers this solution: alongside our engineering thermoplastic standard portfolio, we also offer a special portfolio of food contact materials, fulfilling the specific demands of food technology in terms of safety and performance.

Plastic material solutions for mechanical engineering

Ensinger produces a wide range of plastics, which are predominantly used for mechanical applications and components of industrial machines. The field of mechanical engineering is traditionally focused on steel and metal alloys in order to achieve high mechanical strength and precision of the parts. Nowadays, replacing metal with engineering plastics is common due to their wide range of benefits. High performance plastics can offer a solution where other traditional materials fail, opening up the doors to improvement and progress.

Medical grade plastics

The wide range of Ensinger medical grade (MT) materials offers designers a choice of options to develop innovative medical products, which provide a high degree of safety and added value. The different manufacturing methods used by Ensinger, such as extrusion, machining, injection moulding, profile extrusion and compounding, offer the customer numerous ways develop and produce its product together with Ensinger along the value added chain.

Plastics for oil and gas

The industry demands of high temperature, mechanical strength and chemical resistance call for the need of materials suitable for the most extreme environments. With extensive experience in the oil and gas field, Ensinger work closely with customers to achieve the optimum solution to fit their application needs. Technical material experts can provide customers with a qualified material recommendation which can be confirmed by practical testing. 

Plastics for semiconductor industry

Of all the industries in which engineering plastics can help engineers solve design problems, the most challenging is the semiconductor industry. Ensinger plastics, suitable for the semiconductor industry, are designed with rigid and demanding environmental concerns in mind.  In addition to that, our specialists have worked directly with engineers in the industry to understand the unique challenges that are associated with all aspects of the manufacturing process.
