We Are

Starting 1951 with processing duroplastics – still known as Bakelite – Theodor Greive increased the enterprise to a successful injection molding company for technical parts. 30 years later in 1980 Dipl.-Ing. Michael Greive enhanced its portfolio to a global exporting manufacturing company of medical disposables.
30 fully automated injection molding machines with clamp forces of 20 tons – 100 tons produce challenging precision parts with item weights from 0,01 g to approx. 100 g.
Since 2001 all items are produced acc. to DIN EN ISO 9001, ensuring comprehensive product safety and batch traceability. Starting with incoming goods inspection, the items undergo continous documented in-process and end controls.
Greive patents led to Greive assortment of medical disposables (Infusion- and catheter accessories)
As a matter of fact Greive produces and controls under Laminar Flow (clean room production).
By constantly modernizing maschines parameters and processing only REACH compliant raw materials Greive provides economic and responsible handling of environmental resources. (EU-regulation for Registration, Evaluation, Authorisation and Restriction of Chemicals)
In 2013 B.Eng. Marius Greive assumed responsibility for Greive’s future competiveness – including dual component injection moulding.


What We Do

  • 3 shift injection molding
  • 30 most modern machines with clamp forces of 220 to 1000 Kn following Greive’s leading principle: No machines older than 10 years!
  • Clean Room production for medical and laboratory applications
  • Dual component injection molding
  • Core control for complex demolding
  • Fire proof separate storage of all customer owned molds


PA, POM, PC, PMMA, ABS, TPE, PP, HDPE, LDPE weitere auf Anfrage.

  • Production monitoring by computerized measuring techniques and documentation
  • Initial samples test reports as well as CPK and CMK analyses on request
  • Technical competent contact persons with decision making authority
  • Design consulting als well as optimized tool design

Waste heat is used sensibly

The waste heat generated by the machines and systems is used to heat the offices and workplaces.

2 components injection molding

Greive manufactures 2K components in micro injection molding for the first time.

Water treatment without chemicals

The machines are protected from corrosion and damage by the cooling water exclusively by special physical cleaning processes. We do not add any biocides or chemical inhibitors and so they cannot get into the groundwater either.



As we are doing well in manufacturing – we got the ISO 9001:2015 certification. As we are even better – we observe the GKV Code of Conduct.
