What are the problems that need to be paid attention to in injection mold processing when designing flange shaping molds?

Precision hardware can be cut according to production needs, and then some small accessories can be cut or CNC processed, and precision hardware must be used as a container for cutting and punching, followed by welding, then sanding, and oil injection. After the accessories are made done. It should be reminded that small parts also need to be electroplated or sprayed on the surface after grinding. There are many cases of batch processing of precision metal parts, so the production method and cycle of precision metal processing are different from the operating specifications and processes of general product processing.

Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The temperature of the first two passes mainly affects the plasticization and activity of the plastic, while the latter temperature mainly affects the activity and cooling of the plastic. Each kind of plastic has a different activity temperature, the uniform plastic, because of the source or grade difference, its activity temperature and differentiation temperature are different, this is because of the equilibrium molecular weight and molecular weight dispersion difference, the plasticization process of the plastic in the injection machine of the different example is also different, so the temperature of the selected barrel is not similar.

PEEK material is a high-temperature, high-performance thermoplastic special engineering plastic with good mechanical properties, chemical resistance, abrasion resistance, and hydrolysis resistance.

PEI (Chinese name polyetherimide) is a thermoplastic engineering resin with an amber transparent solid appearance. It has excellent heat resistance, high strength and rigidity, as well as a wide range of chemical resistance, which can meet higher heat. Chemical and elastic demand. Its unique torsional strength among thermoplastics makes it an inexpensive alternative to small steel cutting parts.

Biomedical materials are a high-tech industry with the most interdisciplinary and knowledge-intensive industries, including metals, polymer materials, composite materials, etc. Among them, medical polymer materials are the earliest developed, most widely used, and most used materials in biomedical materials.
