The Fleima-Plastic injection molding glossary

Medical technology (biomedical engineering) is the application of technical/physical/engineering principles and rules to medicine. Knowledge from technology is applied to enable better diagnostics and therapy for the benefit of patients and doctors (users).

A cleanroom is a room in which the concentration of airborne particles (dust, dirt, bacteria, viruses, fungi, spores) is kept as low as necessary.

Cleanrooms are classified according to their degree of cleanliness in accordance with ISO 14644.

Example:

A class ISO 8 cleanroom, according to ISO 14644, corresponds to a class 100,000 cleanroom according to US FED Std 209E.

FLEIMA-PLASTIC produces injection molded parts in an ISO class 8 cleanroom.

Assembly work, for example the joining of injection molded parts for sterile products, is carried out in a class 7 clean room.

Injection molding (often also referred to as injection molding or injection casting ) is a primary molding process that is mainly used in plastics processing. This process can be used to produce large quantities of molded parts that can be used directly and economically. For this purpose, the respective material, usually plastic, is plasticized in an injection unit using an injection moulding machine and injected into an injection mould. The cavity of the mold determines the shape and surface structure of the finished part. Today, parts weighing between a few tenths of a gram and 150 kilograms can be produced.

The 2K injection molding process is a 2-component injection molding process and is one of the multi-component injection molding processes.

There are various types of injection molding in the multi-component process, all of which have in common that injection molding machines with two or more injection units are required, but possibly only one clamping unit. The components can be injected through a special nozzle or inserted into the mold at different points.

Two or more different plastics, e.g. hard and soft components, are injected one after the other into an injection mold to form a plastic article.

The plastics can be different, but should have a certain adhesion to each other, such as PP/PE, PMMA/PS, CA/ABS and PC/ABS, if a firm bond between the components is required in the end product.

This is the joining of thermoplastics using ultrasonic energy. In ultrasonic welding, mechanical vibrations are transferred to the plastic parts. The induced mechanical vibration creates inter-molecular frictional heat.

The plastic begins to soften locally. This reaction accelerates automatically, as a greater proportion of the vibration energy is converted into heat due to the increase in the damping factor of the plasticized material.

The plasticized material of both plastic components combine and form a homogeneous mass after a cooling phase.

Plastic Y-hose connectors or Y-connectors for medical tubing systems.

Hoses can be attached to the various Y-connectors either mechanically on the outside or by gluing or cold welding on the inside.

Y-connectors made of PC can usually also be sterilized using "hot steam sterilization" (autoclaving).
