Achieving weight reduction by forging eight closely spaced holes without deformation!!
▼Issues - It is necessary to create lightweight holes (Φ20mm x 8 holes) in the inner diameter of the gear. - Due to the thick wall and narrow spacing between the holes, deformation is likely to occur when drilling the holes. ▼Solutions - By clamping the product with a die during molding, we prevented deformation during hole punching. - Simultaneously punching the outer burrs improved production by 10%. - Normally, when punching 8 holes, the material in the gear section deforms and warps, but we solved this issue by innovating the previous process. ▼Specifications Material: SCR420H (steel) Weight: 3kg Dimensions: Φ130 x 148mm Accuracy: -0.5 to +1.5mm Equipment: 2500-ton forging press Quantity: 500 to 16,000 pieces/month ▼Mold We handle everything from mold design to mold production and maintenance in-house. Not only do we manufacture forged products, but we also take on mold design, ensuring product accuracy.
