GWELL Analysis Of Pc Hollow Board Extrusion Line Process


PP PC PE Hollow Sheet Extrusion Line is a new type of hollow sheet extrusion line. It is a new type of hollow sheet extrusion mainly used in the PC and additive manufacturing industries.

As an extruder manufacturer, China GWELL’s pc hollow board extrusion line is mainly manufactured with high temperature plastic technology, which can produce parts with small size and high stability. The processing range is large, and a variety of parts can be easily made, such as plastic plates, plastic fans, etc.

A twin-screw drive drives two rollers, which push in opposite directions, producing a two-piece product from a single die plate. Two different sizes of rollers are available; each with a different size factor to ensure high quality output of multi-batch end products and fast processing times for multiple runs in one run.

What is PP hollow board production line

PP hollow board production line is a material with excellent mechanical properties, good coating and good thermal conductivity. The higher surface area of ​​the PP hollow sheet is a big advantage of high temperature printing. PP hollow board has high transparency and low hygroscopicity.

Therefore, when you want to make a mold, it is better to use this material because it has transparency; it is also better than ABS or ABS-like material because the surface of PP hollow board will be smooth, better than ABS or ABS-like material because PP The surface of the hollow board will not have roughness.

The PP Hollow Board Extrusion Line uses two extruders: two small single screw extruders and two large twin screw extruders. Therefore, China GWELL can make products in various colors according to the needs of customers.

The benefits of PP hollow sheet extrusion line

The pc hollow board extrusion line is co-extruded with PP hollow boards (white and black). The advantages of PC hollow board extrusion line are as follows:

1) Wide range of applications, can be used in food processing, pharmaceuticals, electronic appliances, automotive industry, electronic components, etc.

2) Use small screws to reduce production costs.

3) Products can be easily manufactured from standard equipment using metalworking machines.

4) The structure of the hollow plate is firm, the turning operation is simple, and the turning operation does not produce vibration.

5) High quality products can be easily sold to customers.

Features of PP Hollow Board Extrusion Line

1. The wear resistance, dust removal and shaping properties of the vacuum setting table make it easier to operate.

2. High-speed screw, high-rotation speed matching the deceleration pump and stable pressure for low energy consumption; the extrusion output is 25% higher than other brands, due to the special design of its shaping plate.

3. The unique design of the cooling system and vacuum system of the PP Hollow Board Extrusion Line sizing board ensures high-speed extrusion sizing.

4. The special annealing furnace design makes it easier to control the flatness of the sheet than other brands of extrusion lines.

5. China GWELL As a plastic extruder manufacturer, the softness of the traction roller is designed according to the customer’s requirements.

6. The air volume and low pressure of the hollow plate should be adjusted and easy to operate.

7. The special module is specially designed by Jingcheng Mould for PP Hollow Board Extrusion Line. The double wall thickness of the hollow panel should be in the range of 2mm to 10mm. The edges between the double walls should be in the shape of right angles and diagonals.

8. The anti-UV co-extrusion layer can be single-sided or double-sided, and the outer layer should be sandblasted or smoothed according to structural requirements.

Advantages of pc hollow board extrusion line 

1. Good mechanical properties: The special structure of the plastic hollow board makes it have good toughness, impact resistance, high compressive strength, cushioning and shock resistance, high stiffness and good bending performance.

2. Light weight and material saving: The plastic hollow board has excellent mechanical properties and can achieve the same effect year-on-year. The use of plastic hollow board has less consumables, low cost and light weight.

3. Heat insulation and sound insulation Due to the hollow structure of the plastic hollow board, its heat and sound transmission effect is obviously lower than that of the solid board, and it has good heat insulation and sound insulation effect.

4. There are various types of pc hollow board extrusion line: anti-static type, conductive type, flame-retardant type, modification, mixing, surface spraying and other methods can make plastic hollow board have anti-static, conductive, or flame-retardant properties.

5. The chemical properties of Hollow Extrusion Line are stable: the plastic hollow board can be waterproof, moisture-proof, anti-corrosion, insect-proof, fumigation-free and has obvious advantages compared with cardboard and wood board.

6. The surface is smooth and beautiful, and the color is complete. Due to the special molding process of the plastic hollow board, any color can be achieved by the color matching of the color masterbatch, and the surface is smooth and easy to print.

7. The environmental protection effect is obvious: the plastic hollow board has the characteristics of non-toxicity and non-polluting, and the disposal is simple and will not cause pollution to the environment.

China GWELL As a plastic extruder manufacturer, pc hollow board extrusion line is a new type of environmentally friendly product, which is non-polluting and non-toxic, and meets the requirements of green environmental protection. The product has the advantages of high internal quality, flat surface, high breaking strength, flame retardant, good moisture resistance, zero surface water and steam transmission, thermal insulation, and good energy saving effect.
