Rivi Thermosetting - Rubber (M-Tecs R / H-Tecs R) Magnetic Mold Clamping Systems
Safe, Fast, and High-Temperature-Resistant Magnetic Technology for Thermoset and Rubber Presses
Developed by Rivi Magnetics, the M-Tecs R and H-Tecs R systems are high-temperature-resistant magnetic mold clamping and heating solutions specifically designed for thermosetting plastics and rubber applications. These systems represent a patented technology developed for use in injection, compression, and transfer presses, suitable for both vertical and horizontal press configurations.
In thermoset and rubber processing, high operating temperatures, long curing times, and heavy molds make mold changeover operations time-consuming and potentially hazardous for operators. The M-Tecs R system eliminates these challenges by completely replacing mechanical clamping devices, ensuring safe and uniform mold clamping through magnetic force.
The H-Tecs R range complements the magnetic clamping system with fully compatible integrated or standalone heated platen solutions, significantly improving process stability in rubber and thermosetting applications.
Operating Principle and System Design
The M-Tecs R magnetic mold clamping system generates a full-surface magnetic field between the mold and the press platen. This allows the clamping force to be distributed evenly across the entire mold surface rather than being concentrated at specific points. Such homogeneous force distribution significantly reduces internal stress, deformation, and mold deflection.
The system is available with three different magnetic pole technologies:
Square Pole
Long Pole
Combined Pole (Square + Long)
These configurations enable a wide application range, from small molds to very large and heavy tooling, while ensuring maximum utilization of the press platen surface.
H-Tecs R heated platens can be used either in combination with magnetic platens or as standalone heating solutions. Heat distribution is engineered to be extremely uniform across the platen surface.
