Mold Introduction
Injection mold structure in the form of toys, plastic mold is determined to ensure that the main tool for plastic shape, size, precision and surface quality, is one of the MASTER mold elements of the molding process. By injection molding can be divided into general structural features: dual injection mold parting surface and a single injection mold parting surface,
Single injection mold parting surface of introduction: Since only one parting surface, it is called a single injection mold parting surface, also called two-plate injection molding. This injection mold with a simple structure, and the most. After clamping, move, scheduled to die combination constitutes cavity side of the MASTER pvc pipe fitting mould mold sprue, runner and gate agency has launched on the parting, moving mold for plastic parts and casting system introduced slug . Simple single injection mold parting surface structure, convenient operation, but in addition to using direct gate outside the cavity gate bit Ge can choose the side of the product to release from the parting line.

MASTER reaction injection moulding processing

Injection mold processing , are used in a variety of CNC machining , CNC milling is the most widely used and machining centers , CNC EDM wire cutting and CNC machining in mold NC machining is also very common line cutting is mainly used in various kind of straight wall mold MASTER plastic pallet mould processing , such as punching the convex mold, injection mold inserts in the slider , EDM electrodes and so on. For high hardness mold parts , the use of machining methods can not be processed , mostly using EDM , in addition to the sharp corners of the mold cavity , deep cavity parts , narrow groove , also use the EDM . The CNC lathe is mainly used for processing mold rod class standard parts, as well as rotating body mold cavity or core , die body such as bottles , injection mold pots classes , shaft , disk type parts. In the mold machining, CNC drilling applications can also serve to improve the machining accuracy and shorten the processing cycle role. Die widely used in modern manufacturing components forming products , almost all require MASTER injection molding supplies the use of a mold to complete. Therefore , the mold industry is an important part of the national high-tech industry , is an important and valuable technical resources. System architecture design and optimization of die -piece of CAD / CAE / CAM, and make intelligent tends to raise the amount of pieces and mold forming process standardization , improve mold manufacturing precision and quality, reduce surface grinding -type parts, polishing operations and manufacturing cycle ; research, applied for various types of mold -piece used in high-performance, easy cutting of special materials in order to improve mold performance ; to adapt to market diversification and new product trial , application of rapid prototyping and rapid manufacturing technology system mode technology to quickly manufacture molding dies, plastic injection molding or die casting molds , should be the future development trend of 5 to 20 years of mold production technology.

Micro-cavity insert manufacturing process follows

Micro-cavity inserts production process as follows: ① A parts CAD drawing production reticle on a glass layer 10nm thick chromium plating film, according to the original definition of the light-transmissive and non-transmissive portion; ② wafer pretreatment by degreasing , polishing, pickling, washing purification methods of processing Custom plastic mold silicon surface to improve adhesion of the photoresist and the wafer; ③ aluminum evaporation, vapor deposition on a silicon wafer in a thickness of about 1μm aluminum film; ④ glue thrown in a silicon wafer uniformly coated with an aluminum layer of a positive photoresist film; covered ⑤ exposure, the wafer is coated with photoresist mask with a wavelength of ultraviolet light of 350 m through the photoresist mask selective irradiation; ⑥ development, Crate moldthe wafer was immersed in the developer after exposure, the photoresist was dissolved by the developer and irradiated portions except To get the same mask pattern; ⑦ to glue; ⑧ ICP etching, performed by plasma etching deep grooves; ⑨ to aluminum, the aluminum corrosion removal of the protective film, and ultimately obtained a partial structure micro-cavity inserts.
