Plastic mold plastic molding process is an indispensable part. Plastic mold performance requirements include high hardness, good wear resistance, high toughness, good cracking resistance, good chipping resistance, corrosion resistance of the corrosive plastic and to achieve the design of the processing accuracy. So, the future trend of plastic mold is what kind of it?
The trend of the development of European and American mold steel is that carbon tool steel, low alloy tool steel, high alloy tool steel, have emerged a series of new mold materials, mold standard steel alloying degree is also increasing.
1, the development trend of new foreign plastic mold steel
Easy to cut, good polish plastic mold steel, such as the United States 412, M-300, Japan's YAG, Britain's EAB, Sweden's STAVAX-13, etc .;
Pre-hardened plastic mold steel, such as the United States P20,445, Japan's PDS, Germany MOVTREX-A (2312) and so on;
Overall hardened plastic mold steel, such as the United States A2, D3 and H13;
Corrosion-resistant plastic mold steel, such as the ISO ISO 110Cr-Mo17, Sweden ASSAB's 4Cr13 and so on.
2, advanced mold surface treatment process
Using multi-element co-infiltration, composite infiltration instead of single-element infiltration method to deal with the mold surface.
Coating on the mold surface, the coating can be used are: TiC, TiN, TiCN, TiAlN, CrN, Cr7C3, W2C, etc., can be physical vapor deposition, chemical vapor deposition, physical chemical vapor deposition, ion implantation, ion implantation and other methods Preparation of coating.
High-speed scanners and mold scanning systems provide many of the functions required from the model or physical scan to the machining of the desired model, greatly reducing the mold development and manufacturing cycle.
Mold scanning system has been successfully applied in Europe and the United States mold industry. Such equipment, such as the British company Renishaw's high-speed scanner (CYCLONSERIES2), the scanner can achieve the advantages of laser probe and touch probe complement each other, the laser scanning accuracy of 0.05mm, touch probe scanning accuracy of 0.02 mm.
Third, high efficiency
1, widely used high-speed cutting technology
Generally used for large cover mold, the surface machining accuracy of up to 0.01mm. The high-speed milling after finishing the mold profile, only a little polishing can be used, saving a lot of grinding and polishing time. High-speed machining, drastically shorten the molding cycle, thereby enhancing the product's market competitiveness.
2, rapid prototyping technology and rapid mold making technology
The rapid prototyping technology and rapid prototyping technology used in the combination of mold manufacturing, that is, the use of rapid prototyping technology to create prototype parts of the product, and then based on the rapid prototype of the mold. Application of this technology from the mold design to manufacture completed, the cost is only 1/3 of the traditional method. Rapid Prototype pouring silicone rubber mold for a small amount of plastic parts, very suitable for product trial. The use of aluminum injection mold, injection molding cycle can be shortened 25-30%, greatly reducing the weight of the mold, grinding and polishing time by half.
Fourth, innovation power
In order to strengthen the competitiveness of foreign mold steel production tends to concentrate from the dispersion, multinational mergers of many companies. In order to better compete, these companies have built a perfect, technologically advanced die steel production line and die steel research base, formed several world-renowned mold production and research centers to meet the rapid development of the mold industry.
Editor's language mold industry is the substrate of modern technology, is a relying on technology and quality exist in the industry. Only by increasing R & D efforts, in order to remain invincible in the industry. At present, there is still a certain gap between the domestic mold industry and its foreign counterparts. However, as long as we rapidly absorb advanced foreign technologies and constantly try to improve them, we will surely make a huge breakthrough in the near future.
