Heating Device

Adopt 5-zone independently controlled ceramic heating plate

● Precise temperature control:

Partition control achieves stable temperature management, ceramic heating has uniform thermal conductivity, and comprehensive use achieves the purpose of precise temperature control;

● Energy saving and consumption reduction:

The efficiency of ceramic heaters is as high as 96%, saving about 10%-20% of electricity compared with traditional resistance heating;

● High safety:

The ceramic heater uses high-temperature resistant materials such as alumina, which has fireproof and corrosion-resistant properties;

● Low maintenance cost:

The ceramic heating element has a life of more than 100,000 hours, and there are no mechanical moving parts, which reduces the maintenance frequency.

Operation Screen

The machine is integrated with the operating table, saving space and easy to operate.

Changer Net Device

● Continuous production:

Adopting double-station channel design, two filters work at the same time, realizing non-stop filter change, ensuring continuous and stable production process.

● Stable working process:

When changing the filter, the spare filter is immediately switched to the working state, the pressure fluctuation is small, and the stability of the extrusion process is guaranteed.

● Automated operation:

Equipped with hydraulic system control, supports automatic filter change, and reduces the intensity of manual operation.

Die Head

● Uniform material distribution:

Hanger die head flow channel design makes the molten material flow out of each point of the die lip at basically the same time, theoretically avoiding the problem of material stagnation and ensuring the uniformity of the sheet thickness.

● Lightweight structure:

Compared with the traditional die head, the hanger-type structure is lighter and suitable for high-speed production;

● Precise thickness adjustment:

The dual throttling design and independent temperature control system can accurately adjust the thickness of the sheet, and the temperature difference control is accurate to ±1℃ to ensure flatness.

● Easy maintenance:

The die lip can be designed with a continuous unobstructed flow surface, combined with high-strength bolts and zoned heating system to simplify the cleaning and maintenance process

Three Roller Device

● Precise temperature control and stability:

The three-roll calender driven by the integral motor can achieve precise temperature control through the PID temperature control system, and the temperature error can be controlled within ±1°C to ensure the uniformity of the thickness and flatness of the sheet.

● Efficient production and flexibility:

The calender rollers are driven by servo motors, which support independent adjustment of the speed of each roller to adapt to different materials and process requirements and improve production efficiency;

● Precision control:

The worm gear adjustment system and mirror calender rollers can accurately adjust the sheet thickness (0-2mm range) and maintain surface finish;

Sheet Winding Device

Double-station sheet winding device, cylinder shaft winding core, easy operation and quick roll change.

Case Showcase

【Food package】Hullaf Turkey | Food tray thermoforming machine production line and PP PS sheet extrusion machine line

It's a new project business for feood package products production for this customer;

The client visited many suppliers in China, mainly to find a high-quality, good-service, and rich-experienced machine supplier who could provide the client's technical engineers with a two-month training program on equipment operation. From the start of the project, the client visited the factory, had three interviews, and held multiple meetings to finalize the equipment plan and place the order. It took about four months in total. Currently, the client's equipment is already being produced and used in the client's factory.
