Magnetic quick-mold-change systemsMagnetic quick-mold-change systems

Using magnetic power to clamp tools in place in one or two seconds, a new quick-change system for molds has technology specifically for injection, elastomer, and thermoset molding. The Hilma M-TECS 130 uses electricity to create permanent magnets that hold tools in place, marking Carr Lane Roemheld's entry into the quick-change market. There are no moving parts, and overall wear and maintenance, as well as mold-change time, is said to be reduced. After magnetizing the clamp, no electrical power is needed to keep the system magnetized, which works even in the event of a power failure. The minimum holding force of the M-TECS 130 is 18 kg/sq cm or 256 psi. To demagnetize the system, electricity is reapplied.

For processing molding elastomers or thermosets, a higher temperature M-TECS 210 offers temperature stability up to 210C (410F). Since handling is minimized, tools can be preheated, and because there are no T-slots between the heating element and the mold, greater thermal consistency throughout the tool is achieved. An integrated heater is available, and the magnetic system is able to hold the tool in place, while only penetrating 15 to 20 mm (.59 to .79 inch). Hilma Div.
