Corrugated Hollow Sheet Extrusion Line

Description

Let’s introduce the corrugated hollow sheet extrusion line for you.

Introduction of corrugated hollow sheet

Corrugated hollow sheet, also known as hollow grid board, corrugated board.
It is a board with light weight and hollow structure.

Application fields of corrugated hollow sheet:

Electronics, packaging, machinery, home appliances, advertising and health and other industries.
It’s well known that, it is a new type of environmentally friendly packaging material.
Hollow boards are generally made of environmentally friendly and pollution-free recyclable PP, HDPE resin and various auxiliary materials (From Wiki Article).

Main uses of corrugated hollow sheet:

1. Turnover boxes, parts turnover boxes, food turnover boxes, beverage turnover boxes, pesticide packaging boxes, inner packaging of precision instruments, backing plates and partitions for electronic components packaging, and transportation and storage turnover boxes, etc.;
2. Industrial boards, outer packaging protection for various items, backing boards, racks, partitions, bottom boards, cross boards, etc.;
3. Electronic industrial packaging. The purpose is to prevent other electrified items from coming into contact with it and causing spark damage to the parts due to electrified friction.
4. Advertising decoration: display boards, commodity identification boards, billboards, light boxes, window shapes, etc.;
5. Household use: Temporary partitions of houses, wall panels, ceiling panels, container covers, etc.;
6. For construction engineering: foundation construction drainage board, house wall sound insulation board, indoor ceiling, etc.

Main Features of corrugated hollow sheet extrusion line：

1.Extruder parts: High speed, energy-saving, stable screw, and can increase capacity by more than 25%, compared to other similar machines. The screw unique design can ensure an excellent plasticizing effect and stable extrusion.
2. Screen changer+melting gear pump: hydraulic quick change for the screens can effectively stop the impurities of the raw material and guarantee the sheets quality. The melting pump can make the raw material pressure stable to guarantee the stable extrusion.
3. co-extruder design and feed-block for different colors or different raw material co-extrusion
4. The T die mold is made of high quality alloy mold steel, specially designed flow channels for PP hollow profiles,a highly portable throttling device can guarantee the distribution pressure of the raw material flow inside T die uniformed to ensure the sheets thickness uniformed.
trimming according to customer need.
5. Specially designed for calibration devices: vacuum adjustment system and vacuum display system to make the vacuum on the board uniform and stable.
6. There are two sets of haul off machines. The first set is equipped with 12 pics of wear-resistance rubber rollers and high power, which can simultaneously and uniformly pull the sheets from the vacuum calibrating table. The second haul off machine assists to remove the sheet stress.
7.Transverse cutter: Equipped with precise instant fixed-length cutting, special alloy wear-resistant blades with heating device to ensure the plate’s quality of the cut surface.
8.Corrugated hollow sheet extrusion line adopts fully automatic Siemens PLC touch screen control; the electronic control equipment effectively optimizes the whole line operation and achieves high quality and high output.
