Mdi was proudly featured on the cover of Mold Making Technology
The cover image shows the new Anti-Drool Sprue Bar Device specially designed for stack molding. The patented Sprue Bar Shut-off Device prevents plastic drooling, is compact and easily installed even when retrofitting onto existing nonfunctional systems. No internal springs or other components to contaminate. Dual engagement surface action assures perfect alighnment between the sprue bar and molding machine. Mdi’s patented, Anti-Drool Sprue Bar Device stops material drool through use of a specially designed machine nozzle tip that, upon decompression, employs a steel ball check to automatically seal off material flow, preventing any material leakage from the sprue bar. The result is a cleaner and lower maintenance system that also lowers product cost due to material waste.
