Cold forging is a high-precision shaping technology. It is a closed mold, so the tolerance for the amount of material supply shall be 10, and the average error shall be +/-1 gram. When it is flattened, the roundness error used by the external diameter shall be within 30-40 strips. If the external diameter is too big, work-pieces cannot be placed in. If the external diameter is too small, when it put into the mold to forge, work-pieces’ size will be different, so it cannot meet our requirements. Therefore, we recommend using the automatic cutting and flattening machine.

We produce all parts as required by our clients and we incorporate machinery manufacture with mold design.
