PP/PC hollow lattice plate extrusion machine

Plastic hollow sheet has a wide range of applications and is an ideal substitute for wooden materials, so it is widely used in product packaging, construction and other industries. PACKER's hollow sheet extrusion production line has high reliability and strong adaptability, and can be applied in different production scenarios.

 

  • Detail Introduction

1. What is hollow sheet

Plastic hollow board is also called hollow grid board, double-wall extruded board. It is a product that is extruded from polypropylene as the main raw material. It has the characteristics of light weight (hollow structure), non-toxic, non-polluting, waterproof, shockproof, anti-aging, corrosion-resistant, rich in color, etc. Its superior environmental protection performance is more and more recognized. Now it has been widely used in electronics, packaging, machinery, optomagnetic technology, bioengineering medicine and health and other industries.

 

2. Hollow sheet extrusion production process

The PP/PC pellets and chips are transported to the hollow template extruder through the hopper. Heat the material to 160~170°C under automatic stirring to soften the material. Little organic waste gas will be generated in this process. The softened material is extruded in the hollow template extruder and transported to the cooling system through the conveyor belt. The formed product is cooled to complete the form. After this, final product enters the warehouse after being cut and trimmed.

 

3. Components of plastic hollow sheet extrusion line

Main components of the extrusion line are extruder, quick screen changing device, mold, calibrating table, primary tractor and trimming device, heat oven, laminating device, secondary tractor, cutting device, conveyor, material rack, etc.

 

4. Advantages of PACKER hollow sheet extrusion line

1)High efficiency:
Maximum width can reach 3200mm, and the maximum line speed can reach 15m/min.
2)Production flexibility:
Controllability of product thickness and quality. Same equipment and the same mold can produce 2~6mm products.
3)Strong adaptability:
Our equipment can use recycled materials, leftover materials, and crushed materials for direct production, saving more than 30% of production costs.
4)Extruder:
Specially designed screw, advanced temperature control system to ensure stable plasticizing performance and extrusion efficiency, the motor power is reduced by 20%.
5)Mold:
High-quality alloy die lip and adjustable choke block to provide uniform pressure. High-precision molds are the guarantee for the production of high-quality hollow board products.
6)Vacuum shaping table:
The heat convection system is arranged in a staggered manner to ensure high-precision shaping and cooling.
7)Electrical control system:
Micro-processing unit (PLC) is used to control precise parameters and optimize operating characteristics.

 

5. Application range of PACKER hollow sheet extrusion line

1. Turnover boxes for various parts, instruments and beverages. The backing plate and partition of the inner packaging of precision instruments.
2. Lining boards for various boxes and travel bags.
3. Advertising decoration boards, display boards, product identification boards, billboards, light boxes, window modeling boards, etc.
4. Anti-static turnover boxes and cardboard series products are more suitable for the electronics industry, especially microelectronics companies. Due to their flexible size, structural changes and excellent static discharge performance.
