We employ documented procedures for every step in the manufacturing process from initial program launch through steady-state production in order to ensure consistent performance. We engineer our processes to produce the desired results, monitor those results, and use what we learn to regularly refine our processes as part of our commitment to continuous process and efficiency improvement.
Many of our customers have been with us for 5-8 years or more. Year after year, they experience zero late deliveries and zero returns.
Deep-drawing is widely used. Stainless steel deep-drawing is a surface with a certain depth formed by deep-drawing a metal blank. Deep drawing is an important process or processing method in stainless steel stamping. In the deep drawing process of stainless steel, the sheet metal is used as the benchmark to make deep drawing parts, and the die is used to punch the sheet metal into surfaces of different depths. Among them, sheet metal forming is further divided into two types: sheet metal forming and piezoelectric forming (ie die casting forming and stamping forming).
1. The characteristic of deep drawing processing is that the formed parts have good mechanical properties;
The molded parts are free of deformation and have high dimensional accuracy; they can withstand the pressure of large presses, hydraulic presses and other equipment. Compared with die casting, the formed parts do not need heat treatment, which avoids the structural changes of the parts caused by cold work hardening or low temperature impact. Because the deep drawing process can repeatedly draw the sheet material, it does not require high mold materials and equipment, and can be used in large thin plate parts and structural parts with complex shapes. Therefore, it is widely used in modern industry.
2. Deep drawing is mostly used in parts manufacturing, which can obtain relatively thin and uniform formed parts;
It has a wide range of applications, and parts with simple structure and low precision requirements, such as automobile transmission casings, engine cylinder blocks, engine pistons, valve springs, etc., can be made of this metal material; for precision parts such as gears, bushings, guide rails , crankshaft, transmission casing, cylinder head, etc., are also made of this material. Stainless steel deep drawing requires high precision and surface quality, and it must be ensured that defects such as obvious bubbles, cracks and slag inclusions are not generated. Stainless steel deep drawing is often used in mass production. For large-scale precision auto parts manufacturers, extrusion technology can be used to produce large stamping parts. Stainless steel deep drawing is usually processed by multiple die forming, pressing, extrusion and other processes. After punching, it can be stretched or bent in the radial direction with special tools to obtain a wider size and a larger volume of the cavity. The shallow drawing of stainless steel is suitable for the processing of simple shapes, low precision requirements, and no slag inclusions.
3. During the deep drawing process, the whole or part of the stamping and forming parts with a certain depth in the metal structure can be obtained;
Parts with high dimensional accuracy can also be obtained. Deep drawing of stainless steel is the most widely used and most important processing method at present. It can not only make the stamping and forming of the metal sheet into a complex part, but also make the parts that are difficult to achieve by other processing technologies (such as deep hole forming) to be solved by using the deep drawing process. Stainless steel deep drawing processes the material into complex parts with modeling value through deep drawing and other processes, thereby improving the efficiency of parts in the mass production process and reducing costs. After the metal surface is deep drawn, a relatively stable overall surface layer with a relatively complex shape is formed.
4. Deep drawing is generally used for parts with small batches and short production cycles to reduce the production cost of enterprises;
At the same time, it can also be used for parts with lower surface roughness requirements or larger sizes. According to the different pressures, the deep drawing method can be divided into: extrusion method, rolling method, rolling method, hot pressing method and deep drawing method; Speed is also required. Therefore, the production efficiency is high. The deep drawing method is suitable for the production of parts with small batches and long production cycles, especially for the production of small parts.
5. Stainless steel deep drawing has good surface quality and dimensional accuracy, which can meet product requirements;
Generally, 80% to 90% of metal materials can be saved. For example, the sheet is directly drawn into various shapes such as circles, rectangles, polygons, etc., and can be combined arbitrarily, and the precision of the finished product is high, which is more than double that of ordinary stamping parts, and there will be no deformation and cracking. It is said that deep drawing is a precision stamping process with high efficiency, low cost, no deformation and no waste output. Stainless steel parts have good tensile properties and corrosion resistance, and can be used for welding and cold work hardening after processing to achieve quality requirements. Various specifications and models can also be produced by cold stamping; for metal materials, Small parts that do not require high strength work very well.
