Production and assembly of injection-molded parts in clean rooms

We realize individual projects from the first draft of ideas, to the product development, mold making, production of injection-molded parts or extrusion, the automated assembly to the customization, sterilization and logistics — all made in Germany.

As an OEM supplier, we produce in accordance with the requirements of the GMP and ISO 13485 in controlled areas or clean rooms (ISO class 8) predominantly for our customers in the medical technology, diagnostics and packaging industries.

Dialysis applications

Dialyzor housings

Dialyzers are the heart of dialysis process, used for kidney therapy through hemodialysis or hemodiafiltration. Among other products, SABEU produces dialyzer housings made from polycarbonate and other materials for OEM customers. Besides the injection molding process SABEU also extrudes components.    

Our specialty: We produce housings with wall strengths that are up to 20 percent thinner than comparable products with similar specifications.

Dialysis applications
Bicarbonate cartridges

Bicarbonate cartridges

Bicarbonate cartridges for hemodialysis are produced in a controlled area with subsequent 100% control. For optimal cost structures SABEU can integrate the necessary pre-filters in the plastic molding production process.  

Cell strainers

SABEU produces PP cell strainers with insert molded PET mesh for OEMs, for the filtration of cell suspensions. They are manufactured without manual or automated insertion of the mesh, achieving a considerably better process safety and cycle times. Moreover, the investment costs are lower. The product is packaged into the final blister package by SABEU and supplied “ready-to-sell” to our OEM customers.

Cell strainers

Syringe filters

Syringe filters are used to separate microorganisms and particles from liquids and gases. Typical uses include clear filtration, sterile filtration and sample preparation in the laboratory.

SABEU manufactures different syringe filter models for OEM customers.

Product development

In close dialogue with our customers, we develop specific plastic molding solutions and membranes for future products. We aspire to bring innovative and high-quality products to market acceptance with our customers – always in compliance with the regulatory provisions.

A well-balanced interaction of ergonomics, appearance, functionality, technology and ecology is very important to us. Only the interdisciplinary cooperation between expert divisions guarantees a customer-focused realization of ideas. A systematically designed modular R&D process creates transparency and allows us to step in during any product development phase. Our long-term OEM partners are international companies active in the medical technology, biotechnology, laboratory and packaging industries.

The possibility to develop and manufacture molding tools, membranes and injection-molded parts, and to process them further into the final packaged product, enables us to provide our customers with outstanding quality, safety, simplified sourcing processes and hence fast workflows and optimized cost structures.

Product development

System manufacture

As a system supplier for the medical technology, biotechnology and laboratory industries, SABEU stands both for diligence as well as efficiency in the processing of plastic components and membranes. The reproducible manufacture of components in high numbers using ultra-modern, all-electric injection molding machines, allows the manufacture of components with the highest degree of precision. The subsequent assembly and customization are fully integrated in our plants.

The procedures include multi-component injection molding, in-mold decoration (IMD, IMF), injection embossing, thin-wall molding, micro-molding and extrusion. Production takes place in ISO class 8 clean rooms as well as controlled areas using injection molding machines between 100 and 3,000 kilo newton.

System manufacture

Mold manufacturing

In our state-of-the art mold manufacturing division equipped with CNC-controlled processing machines, we are building new injection molding tools and also maintain, service and repair all our molds. 

The mold design is the very heart of the individual injection molding process. Ultra-precise tools for the injection molding process are the basis for a reproducible and validatable production of complex components in large quantities.

SABEU produces a variety of mold tools​

  • highly precision coated molds
  • multi-component molds
  • hot runner molds
  • multi-stage molds
  • rotary tools
Mold manufacturing


SABEU designs and builds customized equipment for the assembly processes on the basis of DoE’s and our own specifications. They guarantee a high degree of availability and a safe, economic assembly of the products in clean rooms and controlled areas.

SABEU creates its own designs for:​

  • assembly lines
  • rotary systems
  • linear systems
  • automatic testing devices

SABEU manufactures in the following processes:​

  • component assembly (fully automated, semi-automated or manual)
  • Ultrasonic welding
  • Thermal bonding
  • Friction welding
  • Edge over-molding


We refine the finished parts with imprints, laser inscription, metal-coating and other methods. The same quality requirements apply to the refinement in mass production as to the production of the individual components: upon request, we will integrate camera systems into assembly lines and make sure that the products are perfect and the labeling is applied to the proper position. Depending on the needs, various processes can be conducted after or during the assembly procedure:

  • laser inscription
  • imprinting
  • coating
  • joining
  • ultrasonic welding
  • friction welding
  • thermoforming
  • packaging
  • blisters
  • pouches


SABEU is familiar with all common sterilization methods and will help you select the suitable method for your product:

  • gamma
  • e-beam
  • ETO
