Recommended Machining and Welding
Conditions
Polystone
®
G and P can be efficiently machined with all
known tools used in wood and metal processing.
Sawing
Fast-running circular and band saws are suitable. Smooth
surfaces can be achieved when the teeth are lightly set.
Saw blades with teeth more than 5/8" apart are sug-
gested. Especially with PP, fast chip removal is essential to
prevent melting.
Milling
Fairly high feed rates and revolutions work best with atten-
tion to reduce heat generation. Suggested 9,000-12,000
rpm with a feed rate of 250-350 inches per minute.
Welding
Quality welds are achieved with the appropriate tempera-
ture setting and air pressure. The welding rod must be
compatible, and along with the joint surfaces, both should
be clean before starting.
Thermoforming
A controllable heating system is required that is designed
to provide even heat to each point of the sheet. Typical
heat time is 10 minutes per 1/8" sheet thickness.
