Description:
1. Primarily used for manufacturing transformers, medium and high-voltage insulation components, and other products using epoxy resin produced by APG process. Compared to vacuum casting, this method offers shorter cycle times, higher precision, and fewer defects. Single-station and dual-station models are available based on production requirements, dual-station can be installed with two sets of molds for simultaneous production.
2. Maintains injection pressure during the gelation phase. Continuously feeding new material into the mold cavity compensates for defects caused by shrinkage during curing and reduces internal stress, resulting in high-precision parts with excellent surface quality.
3. The main frame of the equipment is constructed from 10 mm thick steel, with welded joints annealed to eliminate internal stresses, ensuring structural stability and resistance to deformation. Template movement uses high-precision linear guides for smooth operation. The entire machine can tilt horizontally by 5°, enhancing gas venting during molding and making it suitable for complex molds. Hydraulic clamping provides strong rigidity and high clamping force.
4. The hydraulic station features a multi-stage plunger pump and a three-phase asynchronous motor. Each oil circuit is equipped with five hydraulic valves working in coordination. Hydraulic pressure remains constant, while the oil tank and cylinders offer high sealing performance with no leakage. The hydraulic system is heat-resistant and fatigue-resistant, maintaining stable pressure without leakage or vibration under prolonged load.
5. The mold plates feature independent temperature control across multiple zones, allowing targeted temperature adjustment according to actual needs. Heating is achieved via heating tubes, with platinum resistance thermocouples monitoring temperature, ensuring a temperature deviation of ±1°C and uniform gelation.
6. The control system consists of a PLC and a 10-inch touch screen, enabling one-button start, automatic mold closing, pressure holding, and mold opening. All major electrical components use premium brands, ensuring precise control and simple, convenient operation.
7. Equipped with a set of epoxy resin dynamic mixing system.

Description:
1. A single-station APG machine includes one vacuum mixer and two 100L (80kg) vacuum mixing tanks (material feeding carts). A dual-station APG machine includes one vacuum mixer and three 100L (80kg) vacuum mixing tanks (material feeding carts).
2. The mixer features stepless frequency-variable speed control, combined with an 8L vacuum pump to rapidly evacuate air from the mixing tanks.
3. The mixing impeller is separated from the tank lid, helping maintain vacuum integrity after mixing. The impeller employs a thin-film degassing method, ensuring thorough mixing and complete degassing of the epoxy resin.
4. The mixing tanks are heated via thermal oil circulation, providing even heating throughout the resin. Compressed air (0.3–0.6 MPa) drives the injection of mixed materials into the mold. The mixing tanks are equipped with dual safety protection devices to ensure safe operation.
