SMED Electro Permanent Magnetic Chuck For Punching Machine Mold Changing System
Electric control permanent magnetic chuck for quick mold changing system is mainly to improve the efficiency of traditional injection molding machine, puching machine, and mold clamping machine. The system adopts the magnetization and demagnetization action of the electronic permanent magnetic chuck to clip and replace the mould, you can change the mould within 3 minutes. It can either be installed in a new machine, sold as a standard configuration to the end customer, or be retrofitted to the machine in use, it’s both practical and convenient.

Advantages of Magnetic Clamping System
1. Easy Installation
It does not require any changes to the molds,no need to change the appearance and structures, no need punch, just fix the magnetic plate by bolts in the rear panel threaded hole or T-slot of the injection molding machine.
2. High Safety
The Magnetic quick mold change is controlled by Electro-permanent magnet system which is an electrical pulse activates the system in a second (Magnetization): the mold is held by the natural force of the permanent magnets. The clamping force remains constant even in the absence of a power supply, it is still keep strong and continuously magnetic force when power off and does not disappear or loss by time and temperature factors.
3. High Efficiency
Use Magnetic quick mold clamping system can greatly improve the mold change efficiency, drastically reduces mold changeover times (up to 90%) compared to a conventional procedure. QMCS guarantees a uniform mold clamping, that is held using the whole contact surface. Clamping the mold with uniformity allows obtaining good quality parts even with the first molds. The two mold halves are perfectly aligned: friction is minimized, preserving wear of molds and the machine. Generally the mold change and mold clamping only need 3 minutes, large mold change only needs 10 minutes.
4. Save Space
The thickness of Magnetic plate is about 37-50mm, space is small. The magnetic quick mold clamping system does not use platens and other pneumatic and hydraulic components,save more space and make all the peripherals of the mold in the injection molding machine are easy for maintenance and operation.
5. Easy Operation
Magnetic quick mold clamping system clamps molds of any shape and size with strength. A single operator easily and safely performs the operation, without working inside the machine.
6) Economical and Practical
Use Magnetic quick change mold system means eliminating the cost of maintenance and management of brackets, consumables, fasteners.Electricity is only used to fix and release clamping, once the mold is safely held to the correct position, will no longer need to use the electricity. Magnetic chuck application temperature can maximum up to 150°C, machine weight up from 60 tons to 5000 tons.
