The Twincut beside-the-press granulator from Motan Inc. uses a two-shaft, patented cutter design.
The two-stage process progressively reduces the regrind down to an ideal size, making the Twincut well-suited for grinding glass-filled materials and soft thermoplastic elastomers.
The first stage pulls the sprue/part into the cutting chamber, to produce a medium-sized particle. The second stage reduces the particle size more, to give a consistent, dust-free chip. Swinging side-plates fold out, to expose the entire cutting chamber for cleaning, maintenance and inspection.
A force-fed control system in the hopper, called the Bridge-Buster, helps eliminate large runner bridging and material backup.
Twincut comes in three sizes. The TC 68 handles sprues and runners measuring up to 6 inches by 8 inches, designed for injection molding machines with clamping forces of 50 tons of less. It can granulate up to 12 pounds an hour. The TC 1013 accommodates sprues and runners up to 10 inches by 13 inches, for 250-ton presses and smaller, at a rate of 35 pounds an hour. The TC 1517 grinds sprues and runners up to 15 inches by 17 inches, molded on presses of 500 tons and smaller, at up to 65 pounds an hour.
Motan is based in Plainwell, Mich.
