Plastic Injection Molding Medical Parts

Product Specifications

How are plastic injection molded medical parts made?

The first step in custom plastic injection molding medical parts is to create a mold. The mold for the part to be manufactured is designed according to some injection molding guidelines, using computer-aided design, to the specifications of the 3D model of the part. It is then manufactured in two parts, usually by CNC machining. 

Separate halves of the mold are placed and held tightly by the clamping device of the injection molding machine. In the form of granules or pellets, raw materials are placed in barrels where they are heated at high temperature and high pressure until they melt. The molten material is immediately injected into the mold cavity, filling the entire space within the mold. It is then cooled and solidified to form the shape of the mold.

After the material has completely cooled and solidified, the mold is opened by the clamping device and the solidified finished product is taken out. The finished part undergoes several post-processing operations. These operations include removal of excess material and supporting structures, surface preparation, and painting, electroplating and heat treatment as required.

Polyetheretherketone (PEEK) application：

Polyetheretherketone (PEEK) resin is a special engineering plastic with excellent performance. Compared with other special engineering plastics, it has many significant advantages, such as high temperature resistance, excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardant, Peeling resistance, radiation resistance, stable insulation, hydrolysis resistance and easy processing, etc., are widely used in aerospace, automobile manufacturing, electrical and electronic, medical and food processing and other fields.

Product advantages：

Cost advantage:

During injection molding, only the strength of the frame is needed to support the weight of the material, the mold and the frame itself, thereby preventing material leakage; during the entire molding process, except for the action of natural gravity, the material is hardly affected by any external force, so it has the advantages of processing and manufacturing. The advantages of convenience, short cycle and low cost.

Quality advantage:

During the whole production process, the product quality and structure are relatively stable due to no internal stress.

The advantage of flexibility:

The mould of this machine is simple in manufacture and low in price, and is especially suitable for the development of new products with multi-variety and small batch production.

The advantages of personalized design:

During the injection molding process, the product changes color and may be hollow. In the surface treatment of the product, the effect of pattern, wood, stone and metal can be achieved, so as to meet the individual needs of consumers in modern society.
