The development of laser rapid prototyping (RPM) technology for precision mold parts is rapid. China has reached the international level and is gradually achieving commercialization. The main commercialized rapid prototyping processes in the world include SLA(Stereolithography), LOM(Layer-by-Layer Manufacturing), SLS(Selective Laser Sintering), and 3D-P(Three-dimensional Printing). Tsinghua University introduced the SLA250(stereolithography or photosensitive resin laser curing) equipment and technology from the American 3D Company and conducted research and development. After several years of efforts and multiple improvements, it has refined and launched the "M-RPMS- Multi-functional Rapid Prototyping Manufacturing System".
The annual maintenance procedures required for each injection molding position of the mold depend on different mold cycle periods. The following are some maintenance tips for mold accessories, which can be used by every mold user to ensure the effective operation of mold components such as hot runners, heaters, guide pins and ejector pins, and forming inserts, and to prevent unexpected situations. 1. Check if there is any warning sign of rust or dampness at the vent holes. If you notice rust or dampness near the exhaust hole of the hot runner, it indicates that there is condensation inside or the water pipe may have burst. Dampness can cause a fatal short circuit to the heater.
Precision mold accessories refer to the general term for metal parts specifically used on stamping dies, plastic molds or FA automation equipment in the mold industry. Mold accessories include: punches, punches, guide pins, guide sleeves, ejector pins, ejector cylinders, steel ball sleeves, oil-free guide sleeves, oil-free slide plates, guide pin assemblies, etc. Precision hardware specifically refers to the category of hardware processing with high precision requirements within the hardware industry. "Precision" generally refers to the tolerance requirement within 0.05mm, including precision plastic hardware, precision stamping hardware, precision turning hardware, etc., and is widely used in industries such as electronics, watches, and aviation.
