Dynamically Balanced
"A balance test was performed on the 2 x24 70mm spout hot runner manufactured by MDI. The calculations show that the system is 97% balanced with all tips at the same temperature."

John Tauber // Berry Plastics Corporation

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
"We re-tested the “LCP connector” mold which has the special nozzle from MDI. The nozzle performed perfectly and we achieved perfect parts. Your advice was absolutely correct and I thank you for the help. I declare this nozzle to be LCP approved."
