The future Chinese stamping die will replace the imported die and precision stamping parts process bring congratulations

Stamping dies 'precision stamping parts' is a special process equipment for processing materials(metal or non-metal) into parts(or semi-finished products) during cold stamping processing. It is called cold stamping dies(commonly known as cold stamping dies). Stamping is a pressure processing method that uses a mold mounted on a pressure machine at room temperature to exert pressure on the material to produce separation or plastic deformation, thus obtaining the required parts.

At present, the Chinese stamping mold technology has been continuously developed. Precision stamping parts processing molds have been able to produce camera and mobile plastic parts molds, multi-cavity small-modulus gear molds, and 7800 cavity molds with an accuracy of 5mm. Large precision and complex die casting mould has been able to produce the whole pedal die casting mould, the car rear bridge gear box die casting mould, and the car engine shell casting mould.

With the continuous improvement of mold manufacturing technology, the manufacturing process of Chinese stamping dies is becoming more and more sophisticated, gradually catching up with developed countries. Its development mainly shows that the products continue to develop in a larger, more sophisticated, complex and fast economic direction; Technology content is constantly increasing; The manufacturing cycle is continuously shortened; The die production of stamping parts will continue to develop toward the direction of informatization, digitization, refinement, high-speed and automation. Because the price of Chinese stamping dies is relatively low compared to developed countries, it is very popular in the international market.

The development of Chinese stamping die industry has made the total production of stamping parts in China now rank in the forefront of the world, and it has gradually changed from a large importer of molds to a mold exporter. With the development of this speed, it is an inevitable trend that Chinese stamping dies will replace imported molds.

The stamping part is a thin plate hardware, that is, a part that can be processed by stamping, bending, stretching, etc.. A general definition is a part that does not change in thickness during processing. Corresponding to casting parts, forging parts, machining parts, etc., for example, the iron shell outside the car is sheet metal parts, stainless steel made of some cabinets are also sheet metal parts.

The stamping parts have not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold processing process for metal sheets(usually below 6mm). Including cutting, flushing / cutting / Compounding, folding, welding, riveting, splicing, molding(such as car body) and so on. Its distinctive feature is that the thickness of the same part is the same. Interpretation of the 5th edition of the Modern Chinese Dictionary: Verbs, processing of steel plates, aluminum plates, copper plates and other metal plates.

To put it bluntly, precision stamping is a kind of automotive repair technology, that is, repairing the deformed part of the car's metal shell. For example, if the body shell is hit by a pit, it can be restored to its original shape through sheet metal.

In general, basic equipment for stamping parts factories includes Shear Machines, CNC Punching Machines / lasers, plasma, and water jet cutting machines(Laser, Plasma, Waterjet Casting Machine) / Combination Machine, Bending Machine, and various auxiliary equipment such as: unwinding machine, leveling machine, burping machine, spot welding machine and so on.

In general, the three most important steps in the stamping factory are cutting, flushing, cutting, and folding.

Stamping parts are sometimes made into gold. The word comes from English platemetal. Generally, some metal sheets are stamped by hand or mold to produce plastic deformation, forming the desired shape and size. It can further form more complex parts through welding or a small amount of machining, such as chimneys, iron stoves, and car shells that are often used in the family.

Precision stamping parts processing is called sheet metal processing. For example, the use of panels to make chimneys, iron barrels, fuel tanks, ventilation ducts, curved heads, sky garden places, funnels, etc.. The main processes are shear, bending buckle edges, bending molding, welding, riveting, etc., which require a certain degree of geometric knowledge.

Precision stamping parts are thin plate hardware, that is, parts that can be processed by stamping, bending, stretching, and other means. One general definition is parts whose thickness does not change during processing. Corresponding to casting parts, forging parts, machining parts, etc., for example, the iron shell outside the car is sheet metal parts, stainless steel made of some cabinets are also sheet metal parts.

Modern sheet metal technology includes: wire power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water injection cutting, precision welding and so on.
