[VA Case] Cold forging of φ4×t0.8 pipe (L=70)

[VA Case] Cold forging of φ4×t0.8 pipe (L=70)

The project can be completed with cold forging processing only, allowing for short delivery times! There is no need to purchase pipe materials, ensuring stable material costs.

We will introduce a case of cold forging a φ4×t0.8 pipe (L=70). Until now, the longest size for φ4 in cold forging was L=55, and products longer than L=55 were processed by cutting pipe materials, which incurred costs for each process (4 processes) and quality-related items (foreign matter in the inner tube, burrs, etc.). By purchasing coil material (SWCH10A) and performing cold forging, we were able to process φ4 size cold forging with a length of L=70mm. By converting from pipe material to wire material, material costs were significantly reduced, and costs were cut through the automation of full-length inspection and inner tube gauge inspection. [Focus Points] ■ Reduction of man-hours ■ Reduction of material costs ■ Inadequate supply that matches costs due to size *For more details, please refer to the PDF document or feel free to contact us.
