GWELL PP hollow board extrusion line Feature

1. Extruder

As a manufacturer of plastic extruders in China, Gwell employs a specialized single-screw extruder designed for producing PP hollow materials, in addition to utilizing a twin-screw extruder for co-extrusion processes. The production lines for PP hollow boards are categorized into white and black variants, and occasionally, the white material may manifest in the center of the board. To address this, Gwell incorporates the use of two extruders in their operations.

2. T-die

The design of the template has evolved from its original O-shaped hollow configuration to various forms, including M-shaped, V-shaped, and N-shaped structures, ultimately stabilizing in a well-shaped design. Consequently, Gwell advises customers to opt for a well-shaped T-die.

3. Vacuum Setting Table  

China Gwell is dedicated to the development of setting units. The Vacuum Setting Table not only provides efficient cooling capabilities but also enhances the forming process significantly.

4. Cooling part

"Utilize Gwell's innovative cooling rollers and stress-relieving cooling beds to ensure that the board operates seamlessly and achieves its optimal shape."

5. Automatic operation

"The entire system utilizes PLC automatic control to facilitate seamless interaction between the operator and the machine interface, ensuring that operations are both user-friendly and automated."

6. PP hollow board extrusion line screen changer

A hydraulic quick screen changer is designed to facilitate a rapid and efficient screen-changing process. Featuring a dual-station setup and a specialized sealing mechanism, it ensures the stable operation of the screen changer. Additionally, this equipment is utilized in the production line for PP hollow packaging boards, specifically catering to manufacturers of hollow lattice board products.

7. Tractor

The advanced PP hollow board extrusion line features two sets of tractors. The primary tractor boasts high power and a substantial reduction ratio, employing a multi-roller design that ensures excellent low-speed performance and significant tractive force. This allows it to uniformly extract the board from the vacuum setting table simultaneously. The secondary tractor is specifically designed to relieve any stress in the product. Furthermore, the line is equipped with edge trimming machinery to ensure both the effective width and the quality of the board's edges are maintained.

8. Stress relief equipment

The advanced PP PC PE Hollow Sheet Extrusion Line employs a large-area conduction heating mode, which significantly alleviates board stress and enhances the overall flatness of the sheets.

9. Electric control of the whole line

"Advanced technology enables the comprehensive control of all parameters across the entire production line through the utilization of a microcomputer (PLC). This capability effectively enhances the operational characteristics of the entire production process. GWELL proudly stands as a leading supplier of plastic extruders in China."

10. Extrusion die

The high-quality alloy used in the extrusion die lip and choke rod ensures a steady pressure drop from the die inlet to the die lip. Furthermore, meticulously engineered molds are instrumental in producing extruded sheets of exceptional quality.

11. Vacuum calibration table

The thermal convection system of the calibration bench is designed with a cross arrangement, which guarantees the effective cooling of the hot PC resin stream. This configuration ensures that the final extrudate attains the desired shape and precise dimensions. Regarding the forming process, our multi-layer sheet extrusion machines facilitate rapid formation by utilizing setting and cooling methods that do not require cold water. This approach not only conserves energy but also enhances overall efficiency.

12. Dry Vacuum Calibrator

The vacuum calibrator comprises two distinct subsystems, each featuring multiple closed-loop vacuum channels.

Advantages of the PP hollow board

1. Good water resistance. Even if it is completely immersed in water for several days, it will not be deformed by moisture. Acid and alkali resistance, corrosion resistance, no decay, no rust, especially suitable for basement projects, highway and railway bridge piers, and other humid environments.
2. "Cement does not easily adhere to surfaces. Once the formwork is in place, it can be easily removed without the risk of deformation caused by cement sticking."
3. The surface of the plastic template is smooth, and there is no need to brush the release agent, which reduces the cost of cleaning and maintenance. The surface of the construction building is smooth and flat, and no secondary modification is required.
4. Lightweight, high efficiency, easy to open and dismantle the mold, low labor intensity of the handling operation, and high construction efficiency.
5. High support strength, not easy to deform, impact resistance and wear resistance.
6. Low cost. The service life is long, and the number of cycles used can reach more than 100 times. In addition, the used waste boards and leftover materials can be recycled and reused, saving costs and reducing pollution. The comprehensive use cost can be saved by more than 30% compared with traditional wooden formwork.
7. "With a long lifespan and the ability to endure repeated use, the ultimately worn-out plastic template can still be crushed and reprocessed into a new template. This process not only conserves resources but also aligns with the principles of a 'green industry'."
8. "Effective thermal insulation plays a crucial role in reducing the construction timeline."
9. The method of combining with wood can be used for various treatments, and welding can also be carried out, so secondary processing can be carried out flexibly on the construction site.
