DuPont of the United States released a new type of polyimide material "Vespel" SCP series. The Vespel series is characterized by improved durability at high temperatures, and enhanced dimensional stability, chemical resistance and abrasion resistance. It can extend the life and reduce the weight of resin parts, thereby reducing the overall cost.
Plastic mold structure: It mainly includes a female mold with a variable cavity composed of a female mold combined substrate, a female mold component, and a female mold combined card plate. The convex mold combines the substrate, the male mold component, the male mold composite card, and the mold A punch with a variable core composed of a cavity cut-off component and a side-cut combined plate.
In the processing of precision mechanical parts, the requirements for strength and toughness are relatively high. Its working performance and service life are closely related to its surface performance. The improvement of surface performance cannot be achieved solely by materials, and it is also very uneconomical. However, in actual processing, its performance must reach the standard. At this time, surface treatment technology is needed.
