Pharmaceuticals injection molding in the clean room

Process-reliable pharmaceuticals injection molding and blow molding solutions from the ISO 7 clean room.


Maximum precision and purity can only be achieved by those who master material and technology.

We have known the core requirements of the pharmaceuticals industry as a system supplier since 1995.

The growing complexity but also the safe handling of drugs always impose higher functional and purity requirements on packaging material and device. Trends such as single-use products, glass replacement or patient compliance require individual system concepts.

Due to many years of experience as OEM in the pharmaceuticals market, we have all competences on-site to integrate the launch of your components, assemblies or systems. This know-how head start and the knowledge about the interactions of drug and packaging material in long-term contact make us a popular full service supplier in pharmaceuticals injection molding and extrusion blow molding.

Needle-free injection system

An innovative needle-free injection system has been developed jointly with LTS Lohmann Therapie Systeme AG and initial functional systems manufactured. The project was implemented within a few months from the initial idea to the material selection, the construction of molds to the production of functional systems. Both the fear of patients of needles for the injection at the doctor as well as the millions of puncture injuries worldwide for doctors and in hospitals were the motivations for the implementation of this innovative project.

The end result is characterized by safe, precise and easy handling of the whole injection device. The injector (IIS 500 CS) has already been successfully tested on people with a monoclonal antibody in a clinical study. The needle-free injection of a monoclonal antibody was implemented for the first time worldwide with this clinical study. This new type of needle-free injection system should serve as platform in the future for customer-specific applications.  

  • A plastic-compatible mold design with a total of 8 individual parts from the initial idea 
  • Family molds as basis of quick and economic implementation in the pilot phase 
  • Use of COC as glass replacement for complex, thick walled component 
  • Matching of individual parts to functionality and compliance with specifications 
  • Customer-specific coloring of the individual parts 
  • All-in-one by Riegler – design, development, mold making, precision injection molding and assembly in clean room

Quick test for ATP measurement

The ATP detection pen is a highly effective instrument to check for the existence of microorganisms. We were commissioned with the complete revision of the device to make the existing quick test even more efficient, durable and precise.

Due to the unique arrangement of the sealing geometries of static and moving components, we were able to significantly increase the product service life. At the same time, the sensitivity of the test was improved by the specially designed ATP-free manufacturing environment. For both test variants – liquids and surfaces – we are manufacturing a total of eight plastic components in a completely automated manufacturing and assembly process on multi-cavity tools constructed in-house.

  • More efficient due to high level of automation, plastic-compliant tool design and glass replacement
  • Highest purity thanks to ATP-controlled production conditions and ISO 7 clean room production
  • Unique sealing geometry for an extended shelf life of more than two years after manufacture
  • All-in-one by Riegler – design, development, toolmaking, precision injection molding and assembly in clean room
  • Quick test for ATP measurement

Efficient dosing systems for maximum usability

We develop and manufacture customer-specific dosing systems, measuring spoons and measuring cups for substances in almost every physical state. Thereby, in addition to the application, the dosing accuracy, leak tightness or also the ease of use of the system are always in the foreground. Particularly for direct contact with sensitive drugs, we increasingly rely on medical grade plastics that have particularly high raw material purity and favorable permeation properties. Our special strength is the matched design of the components with regard to application, leak tightness and sliding and friction forces.

  • Maximum dosing accuracy and ease of use for the prevention of dosing errors
  • Cost-effective product prices due to highly automated ISO 7 clean room manufacture and packaging
  • Individual packaging and services such as coloring, printing, labeling, packaging

Functional packaging material for maximum patient safety

With the development of new, higher priced and more sensitive drugs, the requirements for the packaging material are also increasing. In addition to the pure packaging task, our packaging materials fulfill a variety of functions relevant for safety such as barrier characteristics, light protection, exclusion of interactions or the simple, intuitive handling. Thereby, the health of the patient is in the foreground at all times. With the performance of Extractable & Leachable Tests, we can ensure that no harmful substances from the packaging material get into the drug. Already during the selection of the medical / FDA grade, we create the basis for a continuously high quality standard and orient ourselves in every production run to an error rate of 0 ppm.
