Reliable Durability
"The 8 cavity mold from Melt Design was a custom tool built back in 2000. This tool runs 24x7x365 and has produced more than 40,000,000 pieces to date. The material we run is S.A.N. The MDI system has proven to be very reliable for us."

Bill Martz // Sun Star Inc.

Perfect Performance
