Expertise in
Medical technology products are subject to strict criteria and specifications. Our production partners therefore conform to the required standards such as EN ISO 13485 or GMP (Good Manufacturing Practice).
We look after the laboratory tests and analyses, technical documentation and certification to country-specific standards – for complete devices or for individual components.

Best Practice: EXIAS
The housing of the EXIAS electrolyte analyzer was plastic injection-molded by astria. For a batch size of 500-1000 units, injection molding is the perfect choice due to the low cost of the tools. Besides reproducibility and adherence to delivery dates, a high degree of processing quality and material quality were also extremely important for customers. astria ensures these requirements are met through manufacturing processes certified to ISO 9001.
At the beginning of a project, customers often contact us with an initial design drawing or concept. We then create a DFM (Design for Manufacturing) analysis and agree on the most important parameters such as interface lines, injection points, visible areas, and surfaces. In addition, we jointly define the quality criteria according to which the parts will be assessed for acceptance at the end of the process – after all, high quality and satisfied customers are the top priority for astria.
In the Moldflow analysis, we simulate all phases of the injection process from material injection to holding pressure. Here the material flow, temperature curves, and cooling are simulated in order to analyze shrinkage, warpage, sink marks, weld lines, and air inclusions in advance. This forms the basis for the necessary corrective measures to be adopted in the design or process. As a result, we are able to prevent tension and surface errors, and to meet the dimensional and aesthetic requirements of the customer from the very beginning.
The result is a high-quality product with the best material properties. The outer components are screwed together with numerous threaded inserts, while pre-assembly of the inner housing parts is achieved through ultrasonic welding. On the outside, important information and the logo are applied by pad printing.
"The handling of the entire process was highly professional. astria provided us with great support from the concept and initial production, right up to volume production of the final parts."
