Cleaning and packaging of individual parts and assemblies for use in cleanroom conditions

Overview

An increasing number of product manufacturing processes are carried out under defined conditions, cleanroom conditions. The respective products and the process steps required for production determine the cleanroom conditions needed. To produce in a cleanroom, some essential prerequisites mus…
Pajunk GmbH develops and manufactures various medical technology products. At the headquarters in Geisingen, Baden-Württemberg, a new production and logistics center has been built, featuring a cleanroom of GMP Class D, covering an area of 1,015 m². (Source: bc-technology GmbH) Various work steps are carried out in the new cleanroom: These include, among others, the production of products for biopsies and anesthesia as well as testing and packaging processes. (Source: bc-technology GmbH) Various work steps are carried out in the new cleanroom: These include, among others, the production of products for biopsy and anesthesia as well as inspection and packaging processes. (Source: bc-technology GmbH) Some components are manufactured using the plastic injection molding process. However, production in the cleanroom has the disadvantage that the machines generate a lot of heat, which results in high energy consumption due to the installed air conditioning units. Therefore, bc-technology, in collaboration with the injection molding machine manufacturer, developed a concept that allows the machines to be integrated into the cleanroom wall without the development of unwanted particles.

(Source: bc-technology GmbH) The injection molding machine is located in the black area of the new production and logistics center. However, it can be loaded and unloaded from the cleanroom. For the injection area, a horizontally flowing filter fan unit (FFU) was attached to the housing of the injection molding machine as a protective zone, ensuring that the components are always kept under cleanroom conditions.

Cleanroom solutions for the manufacturing of medical technology - sophisticated concept allows for the subsequent installation of additional machines

A clean affair: Integration of injection molding machines into the cleanroom wall reduces energy costs and prevents particle ingress

Since the 1960s, Pajunk GmbH has been developing and manufacturing various products for medical technology. To prevent contamination by germs and particles, production must take place in cleanrooms that meet the high standards of the EU-GMP guideline. However, the production of components for biopsy…
