special function:

1. Multi-mode vacuum regulation: suitable for various product forming needs
In response to the differentiated requirements of vacuum action time for products with different structures and materials, the equipment is designed with a triple adjustment mode of delayed vacuum, primary vacuum, and secondary vacuum: the vacuum start timing and duration can be flexibly set according to product characteristics (such as deep cavity structure, thin-walled material), ensuring that the plastic sheet is uniformly stressed and tightly adhered to the mold during the molding process, avoiding product deformation, bubbles, and other problems caused by improper vacuum adjustment, covering the molding needs of products from simple to complex.

2. Efficient demolding solution: Overcoming the difficult demolding problem of high difficulty products
For the industry pain points of difficult demolding of high difficulty products (such as irregular structures and deep cavity designs), the equipment is equipped with dual demolding technology:
Multiple bottom air demolding: By using multiple pulse bottom air blowing, gradually loosen the bonding surface between the product and the mold to avoid product damage caused by one-time demolding.
Pre-demoulding and blowing: Pre-set the blowing program before the demoulding action starts, forming an air gap between the product and the mold in advance to reduce demoulding resistance. The combination of the two can efficiently solve the problem of difficult demolding of high difficulty products, improve the yield rate, and ensure production continuity.

3. Rapid heating technology: Shorten preheating time, save energy, and reduce consumption
The device achieves dual breakthroughs in heating efficiency and energy consumption control, greatly optimizing the startup process:
Rapid preheating: The electric furnace can enter production mode within 5 minutes of overall preheating. The latest energy-saving heating brick only needs 1 minute of rapid preheating, and then stabilizes at a constant temperature for 2-3 minutes before it can be officially produced (traditional old electric furnace preheating takes about 20 minutes), significantly reducing the waiting time for start-up and improving the effective production time per day.
Energy saving advantages: The new energy-saving heating brick saves about 20% of electricity compared to traditional heating bricks, and long-term use can significantly reduce the energy consumption cost of enterprises, combining efficiency and economy.

4. General control voltage regulation system: precise temperature control, easy operation
Adopting a dual stage temperature control design of "master control+independent", balancing temperature control efficiency and flexibility:
Main control module: One main temperature control module can simultaneously manage the basic temperature settings of 60 heating bricks, reducing repetitive operations and improving parameter setting efficiency.
Independent temperature regulation: 60 heating bricks support independent temperature adjustment, which can accurately adapt to the heating needs of different areas of the electric furnace (such as near the edge and center of the mold), avoiding uneven product molding caused by local high or low temperatures.

5. Temperature probe monitoring: Real-time monitoring of temperature control status inside the furnace
Equipped with high-precision temperature probes to achieve visual management of furnace temperature:
Real-time display of the actual temperature inside the furnace, visually observing whether the electric furnace has reached the preset constant temperature state, facilitating operators to adjust parameters in a timely manner.
To avoid heating instability caused by temperature control blind spots and provide a reliable temperature basis for the production of products with different materials (such as PLA requiring precise constant temperature and PET requiring high temperature stability), ensuring batch production consistency.

6. Front and rear dual spray silicone oil device: balancing demolding and anti-static requirements
Design segmented spraying functions for different stages of sheet processing to improve product quality and processing convenience:
Front-end spraying (cow's milk solution): Spray cow's milk solution before the sheet enters the forming process to enhance the surface lubrication of the sheet, reduce the adhesion between the formed product and the mold, and assist in easy demolding.
Back-end spraying (anti-static liquid): After the sheet is formed and processed, anti-static liquid is sprayed to effectively eliminate static electricity on the surface of the sheet and prevent dust adsorption or static electricity from affecting electronic products (such as electronic tray packaging) in subsequent processes.

7. Secondary molding function: ensuring demolding quality and optimizing product form
Add a secondary upper mold action in the demolding process to improve product forming accuracy and integrity:
During demolding, additional pressure is applied through secondary molding to assist in separating the product from the mold and reduce the difficulty of demolding. On the other hand, slight shaping can be applied to the edges and details of the product to avoid deformation during demolding, ensuring a more perfect shape and precise size of the finished product.
8. Rapid molding technology: breaking through the bottleneck of difficult product vacuum forming
Develop rapid molding technology for products with complex structures and high difficulty in forming, such as multi-cavity and deep stretching products
By optimizing the driving structure and pressure control logic of the upper mold, precise and rapid response of the upper mold action can be achieved, ensuring that the sheet can quickly adhere to the mold after heating and softening, and reducing the shape deviation of the sheet before cooling and hardening.
Effectively solve the problems of "loose fitting and poor detail molding" in the process of high difficulty product vacuum forming, and broaden the processing capability of the equipment for complex products.

9. Delayed cold air and water spray: accelerates cooling and improves production efficiency
Through active cooling design, the cooling cycle of the product is shortened, helping to improve production speed:
Delayed cold air: Delay the start of the cold air system after the product is formed, continuously taking away the surface heat of the product and accelerating the solidification and shaping of the product.
Spray cooling: For products with thick walls or slow thermal conductivity, the spray function can be activated to quickly cool down through water mist, further shortening the cooling time. The combination of the two can significantly increase the production quantity per unit time and adapt to the needs of large-scale mass production.

10. Vibration demolding: Efficient production of difficult products, ensuring demolding safety
Specially designed for high difficulty products (such as deep cavities and irregular curved surfaces) with vibration demolding function:
During demolding, high-frequency and low-amplitude vibrations are used to gradually break the adhesion between the product and the mold, avoiding product damage or mold damage caused by forced demolding.
The vibration parameters can be flexibly adjusted according to the characteristics of the product, which can ensure safe and rapid demolding, as well as ensure the integrity of the product form, and improve the production stability and yield rate of difficult products.

11. Sheet pulling: optimizing material utilization and reducing loss costs
To address the issue of material waste during sheet processing, design a sheet retraction function:
During production gaps or mold changes, the reverse recycling of sheets can be controlled to avoid excess cutting losses caused by excessive sheet transportation.
Effectively improving the utilization rate of sheet materials, minimizing raw material waste, and promoting long-term use can significantly reduce material costs for enterprises and enhance production efficiency.
