Great Magtech (Xiamen) Electric Co., Ltd is one of the most reliable manufacturers and suppliers of general rectangular electro-magnetic chuck for injection molding machine in China. We warmly welcome you to wholesale high quality general rectangular electro-magnetic chuck for injection molding machine from our factory. Good service and reasonable price are available.
Electro-Magnetic Chuck for Plastic Injection Machine
1. The electro-permanent magnetic chuck quick mold change system greatly improves mold change efficiency. It takes less than 3 minutes to change the mold of the general injection molding machine. For large-size machines, it will shorten the mold changing time from 2 hours down to 10 minutes.
2. The system requires just a single operator for a mold-changing job. Without any tool, the operator can easily handle this system beyond the safety distance of the machine.
3. Standard working temperature: 120℃(150/200/optional)
4. According to the brand and application requirements of the injection molding machine used by the customer, design the corresponding adjustment
Feature of General Rectangular Electro-Magnetic Chuck
Uniform clamping force distribution. The surface of the template is magnetically distributed, and the mold is evenly stressed, which will not cause deformation or damage to the mold
Diversity of magnetic pole types. A better magnetic pole arrangement method is adopted for injection molding machines of different tonnages, and the magnetic force is fully utilized without any magnetic force loss.
Strong suction. The maximum clamping force can reach 16kgf/cm.
Long service life. The template is a rigid structure as a whole, without any moving parts, and is not easy to cause damage.

Electro-Magnetic Chuck Working Principle
Magnetization
During the Mag phase, the magnetic flux is short-circuited outside the magnetic surface, safely clamping the mold with a very limited magnetic depth, so as not to affect any internal part of the engaged mold.
Demagnetization
During the Demag phase, the magnetic flux is short inside the magnetic module frame, perfectly releasing the mold for its changeover.
Clamping Force Uniformity
Traditional clamping focuses the clamping forces around the peripheral edges of the mold. Magnetic clamping generates clamping force over the entire surface of the mold. Once the mold is magnetized it is nearly a part of the machine platen. This increased rigidity equates to higher parts, increased repeatability, and less maintenance of the mold.
Application of Electro-Magnetic Chuck
Package of Electro-Magnetic Chuck
We have a separate wooden box for each production number of magnetic chuck. The wooden box has built-in foam to prevent the product from colliding during transportation. We wrap the wooden box with waterproof tape and cable ties to fix it. Please rest assured to buy it.

Electro-Magnetic Chuck for Injection Molding Machine
The return rate of small batches and multiple varieties after using the electric permanent magnet rapid mold change system is expected to be as follows:
Investment payback period (T) calculation, T= CI/(DC×M×TS); T=payback period (unit: month)
CI=capital investment (yuan); DC=number of mold changes per month; M=machine hourly cost
TS=time saved by magnetic template (unit: hour)

Example:
The capital investment (CI) of a 900-ton injection molding machine is ￥: 260,000
Average 10 times per month; M=1,000 yuan
TS=2 hours saved for each mold change
Payback period (month) T=260,000/(10×1000×2)=13 (months)
