Rubber Press – Symac System

The magnetic modules type SYMPAC feature a sturdy steel structure along with high-quality alnico and samarium cobalt magnets on its inside.
The magnets are arranged in a chessboard pattern by alternating north and south poles, this generating an adhesive force upon their magnetization.
The corresponding activation is carried out by means of an electronic device and is performed in less than one second. The magnetic module remains therefore magnetized if required, without any further energy supply.

Unlike traditional clamping methods, the magnetic system SYMPAC generates a uniform clamping force all over the mold surface, thus avoiding any tension and deformation. In this way, the mold preserves its mechanical features, guaranteeing at the same time a better quality and repeatability as far as the molded parts are concerned.

The SYMPAC system is suitable for all kinds of injection molding machines with threaded holes or T-nuts, thus allowing the exploitation of the entire platen surface. No matter their shape or size, the molds can be easily clamped without having to modify the sub-plate.

The magnetic structure of the SYMPAC module, made completely out of metal, enables an extremely uniform distribution in terms of force and heat all over the surface, thus increasing its versatility. No matter the mould shape to be anchored, both magnetic flux and heat will be able to flow through it smoothly, obtaining on one hand a reduced flux dispersion, and on the other an enhanced force and thermal performance.

As the SYMPAC modules are obtained by machining a single steel block, they offer an extremely high mechanical resistance and ensure a homogeneous heat distribution of 300°C.
Thanks to this advanced temperature technology in combination with our well-established expertise in the field of magnets and their applications we were able to design an extremely sturdy and highly performing magnetic system.

Mold clamping in just a few seconds!

The SYMPAC system offers the possibility of a considerably reduced mold change time as well as of simplified and therefore user-friendly clamping operations.
1. Mold centering of the stationary platen with molding machine open.
2. Closing on the mold.
3. Activation of the SYMPAC system by key-switch.
4. Magnetization by pressing simultaneously the SAFE and MAG button of both stationary and movable platen.
5. Molding machine ready for operation after jut a few seconds.
