All kinds of tools and products used in our daily production and life, as large as the base of the machine tool, the body shell, as small as a blank head screw, buttons and the shell of various household appliances, are closely related to the mold. The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products. Because of the different materials, appearance, specifications and uses of various products, molds are divided into casting molds, forging molds, die-casting molds, stamping molds and other non-plastic molds, as well as plastic molds.

In recent years, the plastic mold industry has developed rapidly in China, followed by increasingly fierce market competition, after joining the WTO, foreign mold manufacturers enter the domestic market, to stand out in the fierce competition, the development of mold standard parts

The industry believes that plastic mold manufacturing enterprises want to break through the bottleneck must improve their own technology. At the meeting of The State Council on October 26, 2015, the Premier also said that today's technological revolution plays a very key role in economic development and promoting economic upgrading, advocating mass entrepreneurship and innovation, and also using innovative means to promote entrepreneurship.

1, the reasonable use of cooling lubrication fluid, play the three roles of cooling, washing and lubrication, keep the cooling lubrication clean, so as to control the grinding heat within the allowed range to prevent the workpiece thermal deformation. Improve the cooling conditions during grinding, such as using oil sand wheel or internal cooling wheel. The cutting fluid is introduced into the center of the grinding wheel, and the cutting fluid can directly enter the grinding zone, play an effective cooling role, and prevent the workpiece surface burn.

Hot runner mold: This kind of mold structure is basically the same as the fine water mouth, which is quite different from the flow path in one or more hot runner plates and hot mouth with constant temperature, no cold material demoulding, the flow path and gate are directly on the product, so the flow path does not need demoulding, this system is also called no water mouth system, can save raw materials, suitable for more expensive raw materials, products with higher requirements, design and processing difficulties, The mold cost is higher.

The mold is divided into fast, medium and slow opening and closing 3 times each, and there is no abnormal sound or blocking phenomenon in the opening and closing process; Mold opening and closing action is smooth, there is no interference. Whether the thimble (cylinder) at the plane will be loosened or stuck after ejecting it;

Mold industry belongs to the basic industry of the national economy, involving machinery, automobile, light industry, electronics, chemical industry, metallurgy, building materials and other industries, the application range is very wide. China's industrial development is rapid, including the development of automobile manufacturing, IT manufacturing and medical devices, so that the entire mold industry ushered in development opportunities.

The quality of the mold is directly related to the quality of the product, production efficiency and cost, which I think we will not disagree. The quality of the mold needs to find problems and solve problems through mold testing, so the mold testing process is very important for injection molding enterprises.

2018 is the festival of football fans, because the 21st Football World Cup is held in Russia, the World Cup every four years, is the happy time of this summer, when speaking of Russia, Chinese people think of..... But the nickname Russians agree with is "polar bear."

Molds, industrial production for injection molding, blow molding, extrusion, die casting or forging press forming, smelting, stamping and other methods to obtain a variety of molds and tools. In short, the mold is a tool used to make molded items, this tool is composed of various parts, and different molds are composed of different parts. It is mainly through the change of the physical state of the formed material to achieve the processing of the shape of the item, known as the "mother of industry" title.
