The future development trend of plastic mould is a step ahead

            Plastic mould is an indispensable part in the process of plastic processing. The performance requirements of plastic mould include high hardness, good wear resistance, high toughness, good cracking resistance, good anti-cracking Angle, good corrosion resistance of corrosive plastics and the machining accuracy of the design. So what is the future trend of plastic mold?

一、 high quality

Europe and the United States steel development trend is that the carbon tool steel, low alloy tool steel, high alloy tool steel, there appeared a series of new mould material, mould standard steel alloying degree is improved.

1. The development trend of new plastic moulding steel abroad

Easy to cut and polished plastic mold steel, such as 412, m-300 in the United States, YAG in Japan, EAB in Britain, stavax-13 in Sweden, etc. Pre-hardened plastic mold steel, such as P20, 445, Japan PDS, German movtrex-a (2312), etc. Corrosion resistant plastic mold steel, such as 110cr-mo17 in ISO, and 4Cr13 of ASSAB, Sweden.

2Advanced mould surface treatment process

Advanced mould surface treatment process.

Can be used in the mold surface coating, the coating has: TiC, TiN, TiCN, TiAlN, CrN, Cr7C3, W2C, etc., can use physical vapor deposition, chemical vapor deposition, physical and chemical vapor deposition, ion infiltration and ion implantation method is the preparation of the coating.

二、 high-precision

High-speed scanner and die scanning system provide many functions for the model or in-kind scanning to process the desired model, which greatly reduces the development and manufacturing cycle of the mould. The die scanning system has been successfully applied in the European and American mould industry. This aspect of the equipment, such as Britain, lenny salt company high-speed scanners (CYCLONSERIES2), the scanner can realize complementary advantages, laser measuring head and contact probe laser scanning accuracy of 0.05 mm, contact head scanning measurement precision up to 0.02 mm.

三、 high efficiency

1 High speed machining technology is widely used

Generally used for large covering parts, its surface machining accuracy can reach 0.01 mm. After finishing high speed milling, the mold face can be used with only a little polishing, saving a lot of time for grinding and polishing. High speed cutting process greatly reduces the molding cycle, thus improving the market competitiveness of the products.

2 Rapid prototyping technology combined with fast molding technology

The rapid prototyping technology and rapid prototyping technology are applied to the mold manufacturing, which is to make the prototype of the product parts using the rapid prototyping technology, and then quickly make the mold based on the prototype. The cost of applying this technology from the mold to manufacturing is only 1/3 of the traditional method. A quick prototype of silicone rubber mould is used for a small amount of rolled plastic parts, which is suitable for the trial production of products. It can shorten the injection molding cycle by 25-30%. It can reduce the weight of the die and reduce the polishing time by half.

四、Innovative impetus

  In order to strengthen competitiveness, the production of foreign die steel tends to be concentrated in a decentralized way, and a number of companies are merged. In order to better compete, these companies have built a perfect, advanced technology of die steel production line and scientific research base, steel formed several world famous mold production and scientific research center, in order to meet the rapid development of the mould industry. Mold industry is a modern technological base, a technology and quality of the industry. Only by stepping up research and development, can we establish an invincible position in the industry. At present domestic mould industry still exists a certain gap with foreign counterparts, but as long as we quickly absorb foreign advanced technology, and constantly trying to improve the innovation, in the near future will certainly made great breakthrough.
