Rohs/Reach Compliant/Halogen Free Compliance Multi-stroke forging is an efficient and fully automatic production method. After the material is multi-forged and processed, the strength and toughness of the material are improved due to the refinement of the grain and the effect of the shifting of the network structure. Manufacture of non-standard shaped parts. Multi-stroke cold forging screws have a wide range of uses, such as auto parts, bicycle parts, electrical appliances, bearing parts, gear parts, building materials and hardware, power tool parts, mechanical parts, etc.

Rohs/Reach Compliant/Halogen Free Compliance Adjusting Screws (including two-die two-blow screws, two-die four-blow screws, three-die two-blow screws, four-die two-blow screws, and five-die five-blow screws).  Using special progressive multi-stage machines, multi-blow cold forming is the go-to process for applications requiring components with complex internal and external part geometries. This process forms intricate shapes by deforming and splitting metal into the intended shapes, without any loss in material.

Multi-stroke screw (Bushing Nut) Customized 1. Material: Steel, Alloy steel, Stainless steel, Brass, Copper 2. Finish: according to you need (Cr3+Z,Cr3+ZY,CR3+BZ,CR+ Real Yellow Zinc, Ni, Bo, Tin, Passivation, ZnFe, ZnNi, ...etc.) 3. Process Capability: Diameter  M6 to M24 Length:5 to 70mm   4. High quality and competitive prices 5. Prompt delivery time 6. Country of Origin: China / Taiwan 7. Rohs/Reach Compliant/Halogen Free Compliance The bushing can separate two metal parts to avoid direct collision, friction damage or noise generation, while allowing metal objects to move within a certain range. The bushing is an insulator that can effectively block the energy transferred to the bushing. Therefore, when the vehicle is driving in a large pothole or raised area, it can absorb vibration and reduce noise. Products are widely cover bicycles, motorcycles, automotive and other types of products.

Under normal room temperature conditions, the metal is first cut by using a disc element or rod as a base material, and then the material is extruded and flowed in various ways by continuous extrusion. There are a series of molds inside. The metal forging is squeezed beyond the yield strength of the metal, thereby deforming the forging into the desired shape. Since the material properties of each metal are different, the compressive strength of the material cannot be exceeded when the metal is deformed, otherwise the forging will break.
