The Importance Of Plastic Moulds In Our Lives

Smart Mold Technology Limited | Updated: Oct 20, 2017

In recent years, China's plastic mold developed rapidly. At present, plastic molds in the entire mold industry accounted for about 30%, in the mold import and export proportion of up to $number. With the rapid development of China's national pillar industries such as machinery, automobiles, home appliances, electronic information and building materials, this proportion will continue to progress.

At present, the application of plastic products is becoming more and more widely, which provides a broad market for plastic moulds, and also puts forward higher requirements for moulds. Large-scale, high-precision, multi-functional composite mold will be favored.

Plastic mold It is a combination of the abbreviation of plastic abrasive, so plastic mold is just one of many molds. It is mainly used in plastic molding, extrusion, injection, Plastic Mold blow molding and low foam forming the combined mold. This year, with the rapid development of plastic industry and the application of plastic products continue to expand, so the application of plastic mold is not extended.

Plastic mold is mainly divided into two kinds of molds, the first is mainly composed of concave die composite substrate, concave module and concave die Combination card board is composed of a concave die with a variant cavity, the second is a convex die with a variable core, Plastic Mold which is composed of a convex modular base plate, a convex module, a punch combination card, a cavity truncated assembly and a side-section composite plate.

Because of the importance of abrasive in our life, so the mold has become the industrial production of pressure machine and installed in the press of the special tools. Plastic Mold It is through this professional tool that all kinds of metal or non-metallic materials are made into the various shapes we need to make parts and products.

As a variety of products and components are manufactured in accordance with the appearance of the mold, so the quality of the mold determines the industrial production of parts and products good or bad. Therefore, the material, dimensional accuracy and surface smoothness of the mold is very important.

Plastic mold According to the overall functional structure can be divided into: molding system, pouring system, exhaust system, cooling system, ejector system, etc.

At present, plastic products are increasingly widely used in daily life, including injection molding technology accounted for about 80. Injection molding is widely used in many fields such as automobile, architecture, household appliances, food, medicine and so on because of its one-time forming, precise size, Plastic Mold can bring inlay piece, high productivity, easy to realize modernization, and less processing quantity. The selection of plastic mold, for the plastic industry production can receive good economic benefits is very important, therefore, mold designers understand the basic requirements of mold materials and select the appropriate material is necessary.

The working condition of the plastic mould is different from the cold stamping die, generally must work under the 150℃-200℃, besides under the certain pressure effect, Plastic Mold but also must withstand the temperature influence. Based on the use of plastic molding mold conditions, the different processing methods of plastic mold steel basic performance requirements are summarized as follows:

The hardness of the plastic mold is usually below the 50-60HRC, after the heat treatment of the mold should have enough surface hardness to ensure that the mold has enough stiffness. Die in the work due to plastic filling and flow to withstand greater pressure and friction, Plastic Mold the mold to maintain the shape of precision and dimensional accuracy of stability, to ensure that the mold has enough service life. The wear resistance of the mould depends on the chemical composition of the steel and the hardness of the heat treatment, so the hardness of the mould enhances its abrasion resistance.

Excellent cutting processing property

Most plastic molding molds, in addition to EMD processing also need to carry out a certain amount of machining and fitter repair. Plastic Mold In order to prolong the service life of cutting tool, improve cutting performance and reduce surface roughness, the hardness of steel for plastic mould must be suitable.
