Production process for small die-forged items

Higashi Nihon Tanzou Co., Ltd. manufactures both cold-, warm- and hot-forged products. Production process for small die-forged items

Open-die forging

Machining of aerospace component
Machining of aerospace components

Hand forging is suitable for large-scale and small-quantity production, because it is not confined to specific dies.

Our hand forging is the art of shaping aluminum metals by pressing
between flat or simple contour dies.

Forged Products

Guaranteeing the reliable quality of forged products requires the accumulation of material and forging technology, optimized processing equipment, and operators’ skills.

Forged Products

Closed die forging

Forging using dies close in shape to the final products

This forging method uses dies shaped almost like the final products, making it possible to minimize the machining process or omit it altogether.
It’s suitable for mass production because it produces few variations in quality or size discrepancies.
