Every procedure of making JACRAFT product is carefully designed and rigorously executed. Quality check goes through the whole production process.

Sophisticated Forging Skills

Hot forging, also known as hot stamping, is the process by which metal is heated and shaped by plastic deformation by suitably applying compressive force. Brass hot forging is the core technique of JACRAFT. It is not advanced technology, but essence of traditional skill which is extracted from JACRAFT's over-20-year-experience. Hot forging refines the grain structure and improves physical properties of the metal. With proper die design and forging parameter setting, the grain flow can be oriented in the direction of principal stresses, and grain structure can be improved. Physical properties (such as strength, ductility and toughness) are much better in a forging than in the base metal, which has crystals randomly oriented. Forgings are consistent from piece to piece, without any of the porosity, voids, inclusions and other defects. Thus, finishing operations such as machining do not expose voids, because there aren't any. Also polishing and coating operations (such as plating or painting) are straightforward due to a good surface.

CNC Machining

We pay close attention to the latest technologies which can optimize production process without lowering product quality. CNC machining technology was fast developing in last decade. CNC machinery has been employed to our machining process for best precision acquiring for years.

Polishing

Our sophisticated polishers master the brass polishing skills and understand how to make glossy surface without losing perfect curve and shape for best preparation to coating. Every piece of brass strictly goes through 7-stage polishing procedure from grit grinding to glossy polished surface.
