what is stainless steel bending service?

If the stainless steel bending service radius is smaller than the thickness of the material, a punch with a radius at the front end smaller than the thickness of the material must be used, and resort to the imprint bending method. In this way, it requires 10 times the pressure of free bending.

As far as free bending is concerned, the punch and die are processed at 85 ° or less (smaller is better). When using this set of molds, pay attention to the gap between the punch and the concave mold at the bottom of the stroke, and enough to compensate for the springback and keep the material bent excessively about 90 °.

For bottomed concave mold bending, the mold angle is generally 86 ~ 90 °. At the bottom of the stroke, there should be a gap between the male and female dies slightly larger than the thickness of the material. The forming angle is improved because the tonnage of the bottomed die is larger (about 4 times that of free bending), which reduces the stress that usually causes springback within the bending radius.

The embossing bending is the same as the bending of the bottomed concave mold, except that the front end of the punch is processed to the required bending radius, and the gap between the convex and concave molds at the bottom of the stroke is less than the material thickness. Due to the application of sufficient pressure (about 10 times of free bending) to force the front end of the punch to contact the material, springback is basically avoided.

In order to select the lowest tonnage specification, it is best to plan for a bending radius greater than the thickness of the material, and use the free bending method as much as possible. When the bending radius is large, it often does not affect the quality of the finished part and its future use.

Below is some questions you may want to know:

Questions: How to know the chemical composition of stainless steel deep drawing parts according to our requirements?

Answers: When we offer samples or batch parts, we will also send you our material list from our material factory, it shows more detailed.

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.
