Plastic mold future development trend to take a step ahead
Plastic mold is an indispensable part of plastic molding process. Plastic mold performance requirements include high hardness, good wear resistance, high toughness, good resistance to cracking, good resistance to collapse, good corrosion resistance to corrosive plastics and to achieve the design of the processing accuracy.So, the future development trend of plastic mold is what?
First, high quality
European and American mold steel development trend is, carbon tool steel, low alloy tool steel, high alloy tool steel, have appeared a series of new mold materials, mold standard steel alloying degree is also increasing.
1, the development trend of foreign new plastic mold steel
Easy to cut, good polished plastic mold steel, such as the United States 412, M-300, Japan's YAG, the British EAB, Sweden's STAVAX-13;
Pre-hardened plastic mold steel, such as the United States P20,445, Japan's PDS, Germany MOVTREX-A (2312) and so on;
The overall hardened plastic mold steel, such as the United States A2, D3 and H13;
Corrosion-resistant plastic mold steel, such as GB ISO 110Cr-Mo17, Sweden ASSAB's 4Cr13 and so on.
2, advanced mold surface treatment process
The surface of the mold was treated by multi - element permeation and compound infiltration.
TiCN, TiNN, CrN, Cr7C3, W2C, etc., can be achieved by physical vapor deposition, chemical vapor deposition, physical and chemical vapor deposition, ion infiltration, ion implantation and other methods to achieve the coating Preparation of coating.
Second, high precision
High-speed scanners and mold scanning systems provide a number of functions required from model or physical scanning to the desired model, greatly reducing mold development and manufacturing cycles.
Mold scanning system has been successfully applied in Europe and the United States die industry. This equipment, such as the United Kingdom Renishao high-speed scanner (CYCLONSERIES2), the scanner can achieve laser probe and contact probe complementary advantages, laser scanning accuracy of 0.05mm, contact probe scanning accuracy of 0.02 mm.
Third, high efficiency
1, widely used high-speed cutting technology
Generally used for large-scale cover mold, the surface processing accuracy of up to 0.01mm. After high-speed milling finishing mold surface, only a little polishing can be used to save a lot of grinding, polishing time. High-speed machining, significantly shorten the molding cycle, thereby enhancing the product market competitiveness.
2, rapid prototyping technology and rapid tooling technology combined
The rapid prototyping technology and rapid prototyping technology combined with the use of mold manufacturing, that is, the use of rapid prototyping technology to create parts of the prototype, and then based on the prototype to quickly create a mold.Application of this technology from the mold design to manufacture completed, the cost of only the traditional method of 1/3. The rapid prototyping of silicone rubber mold, for a small amount of plastic parts, is very suitable for the trial production of the product. The use of aluminum manufacturing injection mold, can shorten the injection cycle 25-30%, greatly reducing the weight of the mold, grinding and polishing time reduced by half.
Fourth, innovation and motivation
In order to strengthen the competitiveness of foreign die steel production from the dispersion tend to focus on a number of companies to cross-border mergers. In order to better compete, these companies have built a complete, technologically advanced die steel production line and die steel scientific research base, formed several world famous mold production and research center to meet the rapid development of the mold industry.
Editor of the mold industry is a modern technology substrate, is a relying on technology and quality of the existence of the industry. Only to increase research and development efforts in order to be invincible in the industry. At present, the domestic mold industry and foreign counterparts still exist between the gap, but as long as we quickly absorb foreign advanced technology, and continue to try to improve innovation in the near future will be a huge breakthrough.
