The first: vacuum plastic molding in. Vacuum plastic molding in the production of plastic tray type also have single and double type two kinds. More than single type blister tray for small motor (such as a vacuum cleaner motor, electric tools, etc.) as well as the wire disc packaging, transport, etc , the recent development of faster, and give priority plastic pallet supplier to with special. Type double blister tray are packaged, in two forms: the upper piece of fixed length, width of the plastic panel, the second half of the piece for a large vacuum suction plastic products; On, the second half of the pieces are large vacuum suction with molding Product. The plastic molding need large vacuum equipment, lower equipment cost, mould cost is lower, but the product thickness is not uniform.
The second: extrusion - hollow blow molding in the. Plastic tray extrusion - hollow blow molding and blow molding hollow products in general is similar to, but because of its product is bigger, and the double type, need larger extrusion machine, clamping machine and mould, etc.
But the mold, the equipment investment is much smaller than injection molding, process is simple, low cost, but products not dense, flatness is poorer, uniform wall thickness control more difficult.
The third: extrusion molding in the production of plastic pallets are packaged. Namely, using equipment of extruder, head, respectively extrusion as upper and lower panels with slats and as support in connection with the complex wing of i-section connecting plate, and then carry on Assembly. The emergence of wood plastic composite, promote the development of the extrusion molding in the plastic tray. It is a natural plant fiber (including wood powder shells, straw, rice husk, etc.) and waste plastic as main raw material, make plastic tray has woodiness feeling already, again Has the advantages of resistance to water, the pest and planing, sawing, nailing.
Fourth: injection molding in. Injection molding in the production of plastic tray products smooth, bright and clean, crisp, and close-grained, product design degrees of freedom is bigger, can be divided into double integral plastic tray and double packaged plastic tray.
Double-sided packaged type tray, the tray type double integral is drum spill containment divided into two pieces, molding and then assembled respectively. Although this product should be 2 vice mold, mold structure is greatly reduced, mold the total investment is still cheaper than integral, at the same time to lock equipment Requirements also reduces the mold force, clamping force 1500 tons or more, general plastic processing plants are relatively easy to do. This way of production may become the mainstream of plastic tray production.
Styles of plastic tray: grid light plastic tray, flat light plastic tray, grid, nine horn plastic tray, plate nine plastic tray, plastic tray grid sichuan words, the tablet of sichuan plastic tray, grid field words plastic trays, plastic flat field words Plate, grid, double-sided plastic tray, such as flat-panel double-sided plastic tray type.
See here most of the new buyer may have dizzy, how should choose? First determine plastic tray to grid or flat surface, then determine what style. Light plastic tray is characterized by: cheap, can be nested, savings Space. Nine feet plastic tray is characterized by: standard load, all can advance hydraulic car, more convenient.
Sichuan word plastic tray is characterized by: the standard load, can be spill plastic pallet built-in steel pipe, can be on the shelves, two sides can use hydraulic car, forklift used all around, suitable for turnover shelves or ground. Tian word plastic tray features are: the standard load, can stack, all around Can use hydraulic cars, but push to have 2 road slope, relative is not very convenient. Double-sided plastic tray is characterized by: load is better, can use stacking, cannot use hydraulic car, can only be used machinery forklift truck.
