Why is the HYX thermoforming machine energy-efficient?

I. Heating System (Core of energy efficiency; accounts for the majority of total power consumption)

1. Three-zone independent temperature control (upper and lower sections) combined with high-efficiency far-infrared heating elements ensures precise heating only in the sheet forming area, eliminating the need for full-power heating of the entire oven. Linked oven movement and power control—heating occurs when the oven advances, and power cuts off automatically when it retracts—prevent energy waste from "dry heating" (idling).
2. Smart digital power regulation adapts to grid voltage fluctuations and automatically adjusts output power for higher thermal efficiency; overall energy savings exceed 30% compared to older models.
3. Built-in thermal insulation structure within the oven enables enclosed heating, minimizing heat loss and reducing the power required for continuous reheating.

Intelligent Temperature Control Principle: Heating bricks equipped with 4-wire K-type thermocouples serve as the master control points (Position C3), while 2-wire heating bricks in other zones adjust based on the master control. The master control zone utilizes a Japanese Yamatake temperature controller, achieving precision within ±1°C. The 2-wire heating zones can be individually adjusted based on specific product forming requirements. This design reduces the number of thermocouple probes, thereby minimizing signal interference and failure rates.

II. Fully Servo-Driven Power System

Servo motors drive sheet feeding, forming, and stacking, delivering power on demand and ensuring low power consumption during standby. Unlike traditional motors that run at constant power, this system significantly reduces energy waste during idling while improving positioning accuracy and saving electricity.

III. Process and System-Wide Energy Efficiency

1. Closed-loop circulating water cooling system offers high efficiency and shortens forming cycles; shorter equipment runtimes for the same output result in indirect energy savings.
2. HYX integrated multi-station positive/negative pressure system (heating, forming, cutting, and stacking) consolidates processes, eliminating the extra energy consumption associated with multiple machines and transfer mechanisms. This enables higher production speeds (fastest cycle: ~2 seconds per mold) and lower energy consumption per unit.
3. PLC-based intelligent system scheduling synchronizes vacuum, air-blowing, and heating sequences to prevent inefficient, unloaded operation of mechanisms and optimize overall energy consumption.

Illustrative Example (HYX-7161 Fully Automatic Positive and Negative Pressure 4 Stations Thermoforming Machine)

The unit has a rated power of 110 kW; however, thanks to the aforementioned energy-saving design, actual stable power consumption is only 30–50 kW/h. Rated power does not equal actual power consumption, resulting in significant electricity cost savings during long-term production.
