- Forging is the shaping of metal using localized compressive forces. It can produce a piece that is stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, its internal grain deforms to follow the general shape of the part. As a result, the grain is continuous throughout the part, giving rise to a piece with improved strength characteristics.
- Production forging involves significant capital expenditure for machinery, tooling, facilities and personnel. In the process of hot drop forging, a high temperature furnace is required to heat the billets before it is pressed and deformed under the massive weight of over thousands of kilonewton (hundreds of tons) by large forging hammers.
- Forged pieces taking the general shape are trimmed before the second step of machining. In most cases the semi- finished pieces need to get deburred as in grinding pools following final checks and packaging.
- Drop forging is a forging process where a hammer is raised and then "dropped" onto the workpiece to deform it according to the shape of the die.
- Our brass alloy products are made by above mentioned drop forging method using 100t ~ 1.000t electric friction screw press machines. Certified copper alloy to China code #57-3 or similar German reference #CW614N and #CW617N are monitored throughout the whole production.
