injection mould design the main ingredients of PVC

PVC (full name Polyvinylchlorid),injection mould design the main ingredients of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table top  MASTER injection mold maker  layer mask is painted, the main ingredient in the middle of the PVC, the lowest level is adhesive-backed. It is loved by the world today, is quite popular and is also widely used as a synthetic material. It's the world's second highest usage in a variety of synthetic materials. According to statistics, in 1995 only one year, PVC production capacity in Europe,  MASTER china mold company  there are about five million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption of an average of 1.4 million tons. PVC pipe (PVC-U pipes) rigid PVC pipe, PVC resin and by the stabilizers, lubricants, etc.

plastic injection mold makers the design of the mold

 plastic injection mold makers 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 of every mill exhaust ducts number four, MASTER plastic injection mold makers 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 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 MASTER mould information 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 stay between 0.25-0.5mm; MASTER injection mould 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.

It belongs to the space force structure

Thin-walled spatial structure, also known as shell structure. It's thicker than the other dimensions (eg span) is much smaller, so called thin-walled. It belongs to the space force structure, mainly within the  MASTER plastic injection mold makers axial surface pressure, bending moment is small. Its force is reasonable, material strength can be fully utilized. Shell commonly used in large-span roof structures, such as exhibition halls, clubs, hangars and so on. Thin-walled molds do need to choose the injection molding machine, MASTER injection mould design  such as: DKM high speed injection molding machines, high-precision injection molding machines, special PET injection molding machines, injection molding machines plastic injection mold makers in this high speed, high  efficiency, high safety, high-precision, high energy. Speed ​​is very fast, because the high-speed injection molding machine is a three-axis, which greatly reduces the injection time, while reducing material storage time, MASTER make plastic molds  a model of time and care die time. Thin-wall injection molding material flow is good, there is a large flow length. Having a high impact strength, high heat distortion temperature, good dimensional stability. In addition to the material but also to study heat resistance, flame resistance, mechanical assembly and appearance quality of the material, and so on.

Plastic compression molds

Plastic compression molds Including compression molding and injection molding press two structures mold type. They are mainly used for forming a class of thermosetting plastic mold, its corresponding device is a pressure molding machine. Compression molding method according to the plastic properties, the mold is heated to a forming temperature (typically 103 ° -108 °), and then a good measure pressure plastic powder into the mold cavity and the loading chamber, closed mold, high fever, high pressure in the plastic viscous flow was softening, after a certain time curing stereotypes, MASTER wheel covers molding shape into a desired product. Pressure injection molding and compression molding is different from a separate feed chamber to the mold is closed before plastic injection mold makers molding, the plastic in the feed was preheated Interior Finish viscous flow state, extruded under pressure to adjust the mold cavity and hardening the molding. Compression molding of thermoplastic mold also used some special molten thermoplastic such as the difficulty (such as poly vinyl fluoride) blank (cold forming), high optical performance resin lenses, slight foaming nitrocellulose car steering wheel, etc. . MASTER plastic rattan garden furniture mold   Compression molds mainly by the cavity, chamber, guide mechanism, introduced parts, heating systems and other components. Pressure injection molds are widely used for packaging of electrical components on. Pressure plastic mold manufacturing and injection molds used basically the same material.
