Plastics are used a lot in medical parts. Injection molding is used widely as the method of their manufacture.
Therefore, it can also be said that a substantial part of the medical parts are
being manufactured using molds.
Some typical medical parts made of plastic are the following.
1. Cylinders of syringes (injection tube): PP, PE
2. Pistons of syringes: PP
3. Pipette tips: PP
4. Catheters: PVC, PC
5. Blood collection test tubes: PC
6. Petri dishes for culture growth: PS

The plastic materials used for medical parts, depending on the
application, can only be used if they satisfy the quality standards of laws
related to pharmaceuticals and drugs or of regulations of related governmental
ministries or organizations. The use of these materials is limited to plastics
that can withstand sterilization processing by irradiation with ultraviolet
rays or gamma rays, and to plastics that have passed the clinical approval
tests such as blood coagulation reactions or allergy reactions, etc., on human
body.
It is recommended that molds are manufactured using materials
that are resistant to rusting. Therefore, structures preventing corrosion of
the cavity and core are used widely such as using stainless steel or ion
plating coatings, hard chromium electroplating, etc.
In order to stabilize the quality of molded products, since it
is necessary to design delicately even the mechanisms for the temperature
control of cavities and cores, it is necessary to pay attention to the
structures of the cooling circuits and heat pipes. The cooling structure on the
interior of the core becomes extremely important in the case of the tubes of
syringes, etc.
In terms of quality control, removing any dirt or soot adhered
to the surfaces of molds is also a very important point. Setting up of gas
vents and forced suction structures are also being used.
