How Custom Sheet material fabrication work?
The Sheet material fabrication process involves feeding raw plastic materials into an Sheet material fabrication machine, melting them down, and then fabrication them into an aluminum or steel mold. Upon cooling, a production-grade thermoplastic part is formed and ejected for further use or assembly.
