Stamped parts are manufactured through stamping with minimal material consumption. They are lightweight, have good rigidity, and after plastic deformation of the sheet metal, the internal structure of the metal is improved, resulting in an increase in the strength of the stamped parts.
⑵ Stamped parts have high uniformity in size with the same module and good interchangeability. It can meet general assembly and usage requirements without further mechanical processing.
During the stamping process, stamped parts have good surface quality and a smooth and beautiful appearance because the surface of the material is not damaged. This provides convenient conditions for surface painting, electroplating, phosphating, and other surface treatments.
In the continuous production of modern industry, flanges are inevitably affected by factors such as medium corrosion, erosion, temperature, pressure, and vibration, resulting in leakage problems. Due to errors in the processing dimensions of the sealing surface, aging of the sealing components, and improper installation and fastening, flange leakage is easily caused

The company specializes in producing various standard models of flange materials. Flanges are disc-shaped parts that are commonly used in pipeline engineering, and are used in pairs. In pipeline engineering, flanges are mainly used for connecting pipelines. Install a flange plate on the pipeline that needs to be connected. For low-pressure pipelines, threaded flanges can be used, and for pressures above 4 kilograms, welded flanges can be used. Add sealing points between the two flanges and tighten them with bolts. Flanges with different pressures have different thicknesses and use different bolts. Flange, also known as flange or flange It is a component that connects pipes to each other. Connected to the pipe end. There are holes on the flange that can be threaded with bolts to tightly connect the two flanges. Seal the flanges with gaskets. Flange fittings refer to fittings with flanges

⑴. Reasonable mold design. In the progressive die, the arrangement of cutting sequence may affect the accuracy of stamping part forming. For the cutting of small parts of stamped parts, a larger area of punching cutting is usually arranged first, followed by a smaller area of punching cutting to reduce the impact of punching force on the forming of stamped parts.
⑵. Press down on the material. Overcoming the traditional mold design structure, a material gap is opened on the discharge plate (i.e. when the mold is closed, the material can be compressed). For key forming parts, the discharge plate must be made into an embedded structure to facilitate the solution of grinding (pressure) damage caused by long-term stamping at the pressing part of the discharge plate, which cannot compress the material.
⑶. Add strong pressure function. Thicken the size of the unloading insert pressing part (normal unloading insert thickness H+0.03mm) to increase the pressure on the material on the concave die side, thereby suppressing the flipping and twisting deformation of the stamped part during punching.
⑷. Trim a sloping or curved surface at the end of the convex die blade. This is an effective method to reduce punching force. Reducing the buffer cutting force can alleviate the tensile force on the material on the concave die side, thereby achieving the effect of suppressing the flipping and twisting of stamped parts.
⑸. In daily mold production, attention should be paid to maintaining the sharpness of the cutting edges of the convex and concave molds. When the cutting edge wears out, the tensile stress on the material will increase, leading to an increased tendency for the stamped part to flip and twist.
⑹. Unreasonable or uneven punching gaps are also reasons for the flipping and twisting of stamped parts, which need to be overcome.

Flat welding flange refers to a type of flange that is connected to a container or pipeline using fillet welds. It belongs to any type of flange. When designing, check the integrity of the connection between the flange ring and the straight cylinder section according to the integral or loose flange. There are two types of flange rings: those with necks and those without necks. Compared with neck welding flanges, flat welding flanges have a simpler structure and lower material consumption, but their rigidity and sealing performance are not as good as neck welding flanges. Flat welding flanges are widely used for connecting medium and low pressure vessels and pipelines. Flat welding flanges are suitable for pipeline systems with relatively low pressure levels, where pressure fluctuations, vibrations, and oscillations are not severe. The advantage of flat welding flanges is that they are easier to align during welding assembly and are relatively inexpensive, thus they have been widely used. A gasket is a circular ring made of a material that can undergo plastic deformation and has a certain strength. Most gaskets are cut from non-metallic plates or made by professional factories according to specified sizes, and their materials include asbestos rubber sheets, asbestos sheets, polyethylene sheets, etc; Metal gaskets made by wrapping non-metallic materials such as asbestos with thin metal plates (such as white iron sheet and stainless steel) are also used; The issue of flat welding flanges has always been a topic of concern for people, as it relates to the production costs or economic benefits of companies and enterprises. Therefore, the sealing principle of flat welding flanges is constantly being improved and improved.
However, the main design disadvantage of flat welding flanges is that they cannot guarantee no leakage. This is its design deficiency: the connection is dynamic, and cyclic loads such as thermal expansion and fluctuations can cause movement between flange faces, affecting the function of the flange and damaging its integrity, ultimately leading to leakage. No product can be without defects, it's just about trying to minimize the shortcomings of the product. Therefore, when producing flat welding flanges, the company strives to maximize the performance of the product and maximize its effectiveness.
The characteristics of flat welding flanges: Flat welding flanges not only save space and reduce weight, but more importantly, ensure that the joint does not leak and have good sealing performance. The reason for the reduction in compact flange size is due to the decrease in the diameter of the seal, which will reduce the cross-section of the sealing surface. Secondly, the flange gasket has been replaced by a sealing ring to ensure that the sealing surface matches the sealing surface. In this way, only a small amount of pressure is required to tighten the sealing surface. As the required pressure decreases, the size and quantity of bolts can be correspondingly reduced, so a new product with small volume and light weight (70% to 80% lighter than traditional flanges) has been designed. Therefore, the flat welding flange type is a relatively high-quality flange product that reduces weight and space, playing an important role in industrial use.
