ISO
Stone Plastics is fully compliant with ISO 9001:2008 Quality Standards. We know how important it is to follow a quality system to ensure that the parts we produce are made right the first time, every time, on-time.
PROCESS CONTROL
Whether it is mold temperature or injection parameters, our molding process is continuously being monitored. By monitoring the process and comparing it to a standard we can determine the acceptability of the part being produced. This system helps us to differentiate ourselves from our competitors.
TOOLING PREVENTIVE MAINTENANCE
Stone Plastics has its own in-house mold repair and preventive maintenance department allowing us to maintain and repair all of the injection molds we run.
