The Production Process of Formed Components
The forming system for parts begins with designing a mold – typically from steel . This tooling is then machined with extreme accuracy using computer control (CNC). Next, molten resin is pumped under high force into the confined cavity. The compound is allowed to solidify , adopting the form of the cavity. Once adequately hardened, the die releases and the item is ejected . Subsequently, parts may undergo subsequent steps such as deburring or coloring.
