What Are The Processing Technologies Of Plastic Molds

[Larsen Korn]

Generally, if there is a ready-made mold template, it only needs to process the cavity and core, and the fitter does the hole assembly. If everything starts from scratch, it is necessary to start blanking, milling, planing, grinding, the shape of the template, and then start processing the cavity and core. Machining cavity and core are generally processed by wire cutting, EDM, CNC milling machine or machining center

processing methods and processes of plastic molds

common plastic processing tools and machines

1. Measuring tools: caliper, micrometer, dial indicator, standard gauge block, standard angle block, rotary table, angle gauge, projector, reading machine, etc
2. Processing machines and equipment: gong machine, lathe, grinder, drilling machine, CNC (computer gong), spark machine, wire cutting machine, etc
3. Processing method and process: generally, the mold blank is ordered directly from the mold blank factory. According to the mold design drawing, the steel materials such as mold blank, mold kernel, row position, inclined top and insert can be ordered to start processing. According to the processing technology, it is roughly divided into rough processing and finish processing. Mold embryo frame opening: the rough frame is opened first by the gong bed or computer gong, and then the fine frame is opened (it can also be processed by the mold embryo factory, but the corresponding fee shall be paid; some small mold rooms often process themselves in order to save cost, but the efficiency is low and the accuracy is not high). Other parts are also rough machined into rough embryo first, and then refined by computer gong, cremation machine milling operation and wire cutting machine to meet the accuracy requirements of the drawing, Finally, it is assembled into the mold embryo to form a complete set of molds
the process is roughly as follows: CNC processing such as mold embryo, frame opening, mold kernel and row position, copper public processing, lighter processing, cavity machining, fitter processing, polishing, mold fitting and mold test. In actual manufacturing, several processing processes are intertwined, which requires mold designers and mold masters to arrange all links. If one step goes wrong, all the pots will be negative! Rework often causes damage to the mold, and the mold is not beautiful. If you want to remedy it well, you can only refuel, which will increase the time and cost, and many times time is the most important
