Product Process Guidelines:

Nowadays automotive body parts use advanced high strength steel to effectively improve protection from collision, and ensure the safety, main body parts are made from high strength steel materials are lighter and fuel efficient.

Refer to automotive body parts, like beam, roof. High strength steel has been widely used, and spring back is one of the most difficult problems to overcome.

High strength steel (HSS) forming factors, die design simulation and consideration, lubrication and hardness.

Die design preparation and consideration

Generally, the beneficial properties of higher-strength materials, high yield strength, high tensile strength and high level hardness The higher stress require additional cutting clearances between the punch and die as compared to those required for mild and common steel.

Higher-strength steels require careful preparation and consideration before choosing draw forming process.

High strength steel forming requires good lubricants.

As the higher strength steels become hotter and hotter, many lubricants intend to increase their friction characteristics and retard material flow. Use correct lubricants is very important to change temperatures.

Heat treatment and surface coating for forming steel and die should be also considered fully and clearly.

Before making the virtual die, during design, we need to calculate the forces requires for forming, cutting, piercing and trimming, bending, flanging and drawing. Throughout die design, for the original layout and process, CAE simulation have to go ahead, spring back is a common problem for high strength steel and high strength alloy steel. Spring back and spring back compensation should be better to consider before design. yield strengths for mild steel and high strength steel are different, in the range of 25 to 100 ksi.

More and more auto body parts are made from high strength steels, from old 590mpa to current 1180mpa, all our plants have experience from design to trial, if you have similar products, please contact with us.
