There are also more than the number of production companies

There are also more than the number of production companies (nearly 400),yields a miscarriage can be large (2.8 million tons), a small demand (in 2003sold 1.2 million tons the country profiles),reaction injection moulding production can not fully playthe  MASTER plastic injection toy mould  contradiction within the industry, with an annual output of more than20,000 tons less than 10 enterprises, product quality is uneven, poor quality products still have a market, industry quality technical standards too low,is not conducive to technological progress, leading to substitute  MASTER pe pipe fitting mold  aluminum comeback. The high-end market (30%) were occupied by foreign brands, middle and low market unprofitable, intense competition, the final pattern has not yet formed.

Seal is determined through standard tests to assess moisture

Seal is determined through standard tests to assess moisture, high-quality preservation box than similar products of low moisture permeability 200 times, you can keep food fresh longer internationally.
VersatilityDesign  MASTER plastic injection toy mould  for living needs of different sizes, with the repeated use of technology to use ice packs, ice packs can be guaranteed hot cold (ice packs can be frozen to the lowest -190 ℃, the maximum that can be heated up to 200 ℃, can be cut to any size)Environmental
Box-type turnover box can be used both for working finished product shipments, packaging lightweight, durable, stackable. Specifications can be customized according to user needs, size, aluminum edging, can be stamped, dust, elegant appearance. Can be MASTER plastic injection mold makers  used in hardware, electronics, machinery parts, refrigeration, storage, transportation and other industries. Generally hollow board turnover box provided by the customer based on the size of design, so that the most reasonable load, and boxes overlap, the effective use of floor space, increasing the storage capacity of components, saving production costs.

the design of the mold before the mold is opened

Mold design one, the design of the mold before the mold is opened first pop 0.05-0.1mm, easy blowing, to avoid sticking to the former model; 2, inserts and inserts, inserts and columbium mating surfaces MASTER plastic container molding   of every mill exhaust ducts number four, according to the characteristics of the product structure, materials, and beer;, depth is defined as 0.015mm; 3, carrying water to do the entire mold reasonable, adequate, with as much as a principle,it reaction injection moulding MASTER toilet brush mold  should be done every inserts carrying water how many, the choice of a reasonable mold material. In the last election material size necessary to bear.
When the pressure is not deformed afford the smaller the better, can be avoided to avoid empty space where, to reduce weight of the mold. Fourth, processing technology, all of columbium and parts to be heat treated roughing, allowance is generally unilateral MASTER plastic injection toy mould  stay between 0.25-0.5mm; 2, even after heat treatment workpiece drawing back to the grinder together, the workpiece shape and by the number of right-angle grinder to grind. As for the plastic processing is not difficult to impose planes reserved 0.15mm province mill; 3, finishing the workpiece by the grinding machine, the first self-test, and then to detect mold QC, OK before they can be sent to the CNC lathe.

Plastic Injection (plastic) molds It is mainly the production of thermoplastic

Plastic Injection (plastic) molds It is mainly the production of thermoplastic products in the most common type of mold, plastic injection mold corresponding processing equipment is plastic injection molding, plastic injection first heat in the machine at the MASTER trash and recycle bin end of molten heated barrel, then screw in the injection molding machine under or plunger driven by injection machine nozzle and mold casting system into the mold cavity,plastic injection toy mould plastic cooling hardening molding, stripping get products. The structure usually consists of molded parts, injection system, the guide member, the introduction of some institutions, thermostat systems, exhaust systems, supporting members and other components. Manufacturing materials commonly used plastic mold steel modules, MASTER plastic chair mold commonly used material is mainly carbon structural steel, carbon tool steel, alloy tool steel, high speed steel. Injection molding processing methods usually apply only to the production of thermal plastics products, injection molding process to produce a wide range of plastic products, from daily necessities of life to all kinds of complex mechanical, electrical appliances, vehicles, spare parts are used in injection molding, it is the production of plastic products, the most widely used as a processing methods.
