Stainless steel stamping Parts instroduction

1.Stainless steel stamping parts are made of aluminum / stainless steel / carbon steel / alloy steel / brass


2.production process for stainless steel stamping parts: metal stamping / deep drawing / shearing / punching.

3.The operating environment is 16-250T

4. The surface of stainless steel stamping parts is anodized / powder sprayed / painted / galvanized / silvered. The product is not easily affected by the environment during the later use, which causes other problems such as rust..

what is metal stamping?

The stainless steel stamping parts process is a metal processing method, which is based on the plastic deformation of the metal, and uses the mold and the stamping equipment to apply pressure to the sheet material to cause the plastic deformation or separation of the sheet material, thereby obtaining a certain shape, size and performance Parts (stamping parts).

The stamping forming process occupies an important position in the automobile body manufacturing process, especially the large covering parts of the automobile body, because most of the shapes are complex, the structure size is large, some are still curved surfaces, and the surface quality requirements are high, so the stamping process method Making these parts is unmatched by other processing methods. Almost all of the truck's cab, front sheet metal parts, freight car panels, various body covering parts of passenger cars and various skeletons of passenger cars are made by stamping processing methods.

Stainless Steel Stamping Parts

1: Definition of stainless steel stamping Parts
Stainless steel stamping parts refer to stamping parts made of stainless steel materials. The specifications and models of stainless steel vary, and the manufacturers vary. The general stainless steel stamping parts are all processed and produced.


2: Features of stainless steel stampings
(1) The yield point is high, the hardness is high, the cold work hardening effect is significant, and cracks and other defects are prone to occur.


(2) The thermal conductivity is poorer than ordinary carbon steel, resulting in large required deformation force, large punching force and deep drawing force.


(3) The plastic deformation hardens violently when drawing, and the thin plate is easy to wrinkle or fall when drawing.


(4) Deep-drawing molds are prone to sticking tumors, resulting in severe scratches on the outer diameter of parts.


(5) When drawing, it is difficult to achieve the desired shape

SUS304 Automotive Stamping Parts

Below is some questions you may want to know:

Questions: How to guarantee your final size can meet our drawing request?
Answers: we will make moulds according to your 3D drawing. And we also do sampling when batch production start, to make assure the final dimension can meet your request.
Questions: How to make sure the color after painting or powder coating can be correct?
Answers: We have color card with different color number, such as RAL9016, we will contrast the sample surface and color card, to make sure the final surface effect is correct.
Questions: Generally, how do you packing the goods?
Answers: normally, for inner package: the goods is nude, for outer package: carton + plywood. If you have special request for inner or outer package, pls indicate it when you send us new inquiry.
Questions: If we find the defect products exist in the batch parts, how to do?
Answers: Yes,your caution is very good, in fact, when batch production, we need do sampling. Before shipment, we also do testing to make sure the quality is ok. If you found several defect product exists, pls take photos and send your quality feedback, we will check and send you quality products. But pls be assured that our products is qualified, unless caused by the worker's mistake to place.
