Brings New Solutions to Die Stamping Industry

In recent years, with the continuous growth of China's economy, high-tech products have continuously been broken through, and mold design and precision machining manufacturing have begun to develop rapidly. Driven by competition, the price of molds has continuously dropped, profits have gradually decreased, and market competition has become increasingly fierce. Mould makers can only avoid the fate of being eliminated by improving the “cost-effectiveness” of the mold. However, increasing the quality of the mold means investing more money. Therefore, in order to fundamentally improve the cost performance of molds, it is still necessary to select high-quality hard alloy mold materials, because the materials are often the fundamental factors that affect the life of stamping molds. Increasing the quality of materials can also make mold production and processing more effective. .

Chunbaosenla Tianshi Group has been engaged in the production of cemented carbide for 90 years and has grasped the opportunity of the mold industry to meet the demand for quality. At this DMC show, it will launch new key grades for corrosion-resistant carbide, NF series and CF. The series brings new solutions to the die stamping industry.

In addition to the targeted grades for hardness and toughness of the die stamping industry, Chunbaosenla Tianshi also considers the user's problems in machining materials, namely corrosion problems. Carbide is composed of tungsten carbide and cobalt. In cemented carbide, cobalt acts as a binder and improves fracture toughness, but cobalt binders are decomposed due to corrosion during long-time discharge machining or on-line cutting, rusting, affecting the surface quality of the product, causing stamping. When the wear rate is accelerated, the life of the die is reduced. For this incentive, the company has developed NF and CF series grades with corrosion resistance.

CF-H40S, CF-H25S, NFM23, NFM24, NFM25, and NFS26, all have corrosion resistance, but they have different hardness. Therefore, the punching materials are also different. CF-H40S, NFM23, NFM24, and NFM25 are generally used for punching. Steel plate or thick stainless steel plate, hardness between HRA 88.5~90.7, CF-H25S and NFS26 are used for thinning stainless steel plate and copper plate, etc. The hardness is between HRA 90.5~92.1, because both grades are It can protect the surface finish of stamping parts, so the situation of card material, adhesive material and abrasion will be relatively low, and the life of the mold can be relatively improved.

In fact, 2013 was a big challenge for all industries, but for Syrah, there was no significant impact on the sales of stamping die alloys. Instead, there was an increase in sales, mainly due to a number of Domestic and foreign joint venture factories have adopted our new anti-corrosion cemented carbide grades, providing them with a good cost-effective solution, enabling them to move from other suppliers to Serra's products, together with our implicit cooperation with customers. All of these brought us a lot of growth momentum last year.

CF-H40S can be said to be the most popular brand in the mold industry of Chunbaosenla Tianshi. The Chinese industry produces large to miniature cars and home appliances motors. The punches are mainly CF-H40S, NFM23 and NFM24 (KG4). Customers benefit from the cost-effectiveness of molds that can be greatly increased in the manufacture and use of molds. Our company expects that CF and NF series hard alloys will continue to grow in stealth in 2014.

Thanks to the opportunities brought by the growth of the electronics and electric vehicle markets in the world, the precision, yield, and speed of product requirements have also been relatively increased. The rise of the electronic car deployment market has also brought about diversification of products and meets the needs of the entire consumer group. The speed of mold design and manufacturing, as well as the increase in the speed of stamping, is also a trend that can not be ignored. The so-called precision high-speed stamping general punching time refers to more than 1000 times / min, the pressure is more than 100t, stamping machine tools and molds manufactured in this state Labor and stability requirements are very high, and the targeted production is also relatively large, so the mold material needs to be very implicit and wear-resistant. If the die material is not suitable or the service life is not enough, a set of stamping parts needs to be processed. The cost and time used often exceed the value of the mold material itself by more than 100 times. The USB connector, switch key, and steering gear often seen on electronic products As well as lead frames are produced at high speed stamping.

With China's elimination of low-capacity, low-tech industries, rising wages and rising costs, the industry needs to develop in the direction of high-tech, high-automation, and high-capacity. The precision of mold design and materials will also be relatively high. The pursuit will also increase. In the past decade, due to China's cheap labor, intelligentization and automation were often empty talks, and there was no urgent need to implement them. However, with the past three years, due to factors such as salary levels and raw materials, production costs have risen and manufacturers have begun to pay attention. Automation management and material quality management hope to increase the use time of the mold, thus reducing the number of maintenance. The cost of manpower and time required for mold maintenance is not low, if the economic benefits of doing this well are very Appreciable.
