Select Dalian stamping die with guaranteed quality

Stamping is a method of pressing a material at room temperature by applying pressure on the material on the mold of the press to produce a separation or plastic deformation to obtain the required parts. The materials for manufacturing stamping die are steel, carbide, steel bonded carbide, zinc based alloy, low melting point alloy, aluminum bronze, high polymer material, etc..

Dalian stamping mold industry has been the rapid development of the growth rate of about 15%, all components of the system mold industrial enterprises has undergone tremendous changes, in addition to state-owned professional mold factory, collective, joint ventures and private development has been rapid. In recent years, the demand for users of cutting tools has also changed. In the past, knives were commonly regarded as consumables, so the cost of cutting tools was reduced by reducing the use.

Recent changes have taken place in the view that machining costs should be reduced by giving full play to the role of the tool. Because of the high precision, good consistency and beautiful appearance of the products formed by the die, more and more products are used in the structure and interior decoration of aircraft, ships and high-speed trains. In addition, the production process can achieve high efficiency, large quantities of materials and energy saving, so the mold is often praised as the mother of industrial production.

Injection molding process, when the injection pressure is greater than the clamping force, so that the mold parting surface is tight, it is easy to produce overflow edge. In this connection, the booster shall be checked for excessive pressurization, and the product of the projected area of the plastic parts and the molding pressure shall be checked whether or not it exceeds the clamping force of the equipment. Hot stamping dies require coolant passages to ensure that the temperature of the annealed sheet metal is rapidly lowered to below 200 degrees celsius. In the past, it was usually necessary to make a coolant passage by direct drilling in the mold, so it was almost impossible to produce a continuous position on the surface, especially for a complex mold. Stamping is one of the practical processes for mass production of parts.

In the process of stamping production, the most problems appear in the mould, and it is the most important factor in the whole stamping production. Direct impact on production efficiency and cost. Affect the delivery cycle of the product. The problems of mould mainly focus on die damage, product quality defect and grinding of mould. They have been puzzling the production of the industry for a long time.
