Made of indoor and outdoor advertising exhibition display board, publicity posters, dairy drinks and wine display box and other products, this product has waterproof and moisture-proof, anti-aging, exquisite printing, long use time, beautiful and generous, overall vision and other characteristics.
5, Application of PP Plastic Hollow Corrugated sheet/Plate in Refrigerator and Washing Machine
PP plastic hollow plate is a new type of environmental protection products, no pollution, no harm, meet the requirements of green environmental protection. The product has large internal quality, flat surface, high breaking strength, flame retardant, good moisture-proof performance, zero surface water and steam penetration, heat insulation, good energy saving effect. Especially the refrigerator with external condenser has excellent adiabatic effect. The company can make all kinds of refrigerator, freezer, washing machine back and base according to customer's request
Plastic corrugated hollow sheet box making process
1,Raw material perpare
The PP filler masterbatch granulating machine for the raw material production.
The waste PP plastic sheet can be cutting into small chip to use directly,or the waste chip after granulating then for extruder.
The PP granules and filler masterbatch and coloe pigment can be mixing for the extruder.
2,PP hollow corrugated sheet production line
Tongsan professional for plastic PP hollow corrugated sheet making machine ,we can provide all series production line for the sheet width range from 1220mm to 2800mm ,the corrugated sheet thickness range from 2-6mm or 7-12mm.
3,Plastic corrugated box making machine
Corona treatment machine for the surface treatment
In order to improve the surface tension of the hollow sheet surface, and thereby improve the printing ink fastness, the hollow corrugated sheet surface will under corona treatment, so that the surface produces micro-concave dense holes, plastic surface roughening, increase the surface activity.
Box sheet printer machine
The printing machine generally consists of a mechanism such as plate loading, ink coating, embossing, and paper feeding (including folding). It works by first making a plate and image to be printed on a printing press, then applying the ink to the place where the text and image are printed on the printing plate by hand or by a printing machine, and then directly or indirectly Printed on paper or other substrates (such as textiles, metal sheets, plastics, leather, wood, glass, and ceramics) to replicate the same print as the plate.
Die cutting machine for the shape of corrugated box,
The working principle of the die-cutting machine is to use a die-cutting knife, a steel knife, a metal mold, a steel wire (or a template carved from a steel plate), and apply a certain pressure through the plate to cut the printed product or the cardboard into a certain shape. If the entire print is pressed into a single graphic product, it is called die cutting; if the steel wire is used to press a mark on the printed product or leave a bent groove, it is called an indentation.
Welding machine or bookbind edge sealing machine
Plastic welding machines are used to weld thermoplastic engineering plastic sheets or products such as polyethylene, polypropylene, polypropylene, and nylon. During operation, the plastic electrode is melted and melted, and the workpiece to be welded is fused and bonded. It is widely used in the welding and maintenance of plastic equipment, plastic floor laying, plastic pipe connection, plastic bottle sealing and so on.
