Core Advantages
1. Servo-Driven: Energy-Efficient and Precision
The equipment is equipped with a servo motor, servo pump, and closed-loop controller, reducing energy consumption by over 30% compared to traditional hydraulic presses and lowering noise by 15 decibels. Utilizing high-precision pressure and displacement sensors, it enables dual closed-loop precision control of both pressure and position. Pressure fluctuation is stabilized within ±1%, and the slide's repeat positioning accuracy reaches ±0.01mm, meeting the demands of precision micro-structure molding.
2. Multi-Stage Process, Flexible Programming
Incorporating brand PLCs (such as Siemens or Omron) and a touchscreen control system, it supports flexible programming for multi-stage pressure, temperature, and stroke. Users can freely set complex processes—such as "slow mold closing - low-pressure preheating - high-pressure molding - dwell cooling"—based on the product curing curve. Parameters can be saved as recipes and recalled with one touch, enabling intelligent production.
3. High Vacuum Level, High-Quality Molding
An integrated high-efficiency vacuum system, featuring a high-quality vacuum pump, can rapidly evacuate the vacuum chamber to below 50 Pa. The vacuum environment effectively prevents material oxidation at high temperatures, significantly promotes resin flow and wetting, and eliminates pores and short shots in products. It is particularly suitable for the one-shot molding of complex-shaped structures and multi-layer composites.
4. Uniform Temperature Field, Precise Temperature Control
Employing thermal oil circulation heating or electric heating tube zone control, combined with an intelligent PID adjustment algorithm, it ensures uniform surface temperature distribution on the hot platen during prolonged operation. Typical parameters include: maximum operating temperature 200°C–400°C (customizable), temperature control accuracy ±2°C, hot platen flatness ≤0.03mm, and parallelism ≤0.05mm. This guarantees uniform force distribution across the workpiece and minimal thickness tolerance.
