There's a new player in magnetic mold-clamping systems: the Hilma Division of Carr Lane Roemheld Mfg. Co.
Hilma, based in St. Louis, is known for its hydraulic mold clamping systems. Hilma is offering magnets made by Rivi Magnetics of Modena, Italy.
Hilma said the long-pole technology uses double magnets to provide up to 20 percent more clamping force than square-pole magnets.
With the permanent magnets, electric power is required for only two seconds to unclamp. Clamp capacity is not affected by any power loss, Hilma said.
The magnetic systems include safety features such as a mold clamp sensor, temperature probe and light signals.
