The company started processing plastics for medical components back in 1960. This is when the first injection molding machines were put into operation. Plastics have established themselves as indispensable in medical technology and the pharmaceutical industry. Material resistance and individual formability make plastics suitable for a wide variety of applications. Sensitive applications on the human body pose special challenges for materials. This means that the material and its processing must meet the highest standards. The following manufacturing methods are used by sfm in this field:

 

Injection molding:


In injection molding process, the plastic is liquified (plasticized) and injected into a mold. The shape of the mold determines what the finished part will look like and almost any shape could be created. Injection molding is ideally suited for efficient production of large volumes of parts.


Overmolding:


In overmolding, or insert molding, a non-plastic component is placed in a mold as a base (e.g. a cannula or needle). The liquified plastic is then injected into the mold around this component forming a bond between the insert and plastic.


Two-component injection molding:


Two-component injection molding is the process of integrating two types of plastic into one injection mold. This allows you to take advantage of the different properties of the plastics resulting in an optimized end product (e.g. enhanced tactile feel).


 

Our modern injection/micro-injection and over molding department cover 1,250m² of which, 280m² is class 8 cleanroom. About 20 people team members work in this department and affiliated specialty workshop to help implement new injection molding tools in cooperation with high-performance tool manufacturers. The supply of raw material granulate to the injection molding department is fully automated via the granulate distribution system.
