In fact, at present mainly include four kinds of different ways of molding. Vacuum plastic molding in, this way, the first production has single-sided and double-sided plastic tray. Single type blister tray euro plastic pallet for small motor and wire disc packaging, transport, etc. Double blister tray is packaged, divided into two forms: the upper piece for fixed-length, fixed width plastic sheet extrusion, the second half of the piece for a large vacuum suction plastic products; On, the second half of the pieces are large vacuum suction plastic products.
The second way is called extrusion - hollow blow molding molding in, by comparison, this kind of product is bigger, plastic tray type and is a double sided, need larger extrusion machine, molding machine and mold, etc., but the mold, the equipment investment than injection molding is small, the cost is relatively low, the disadvantage is that its products not dense, flatness is poorer, uniform wall thickness control is more difficult.
The third kind is called injection molding in, in heavy duty plastic pallet this way molding plastic tray products has the advantages of smooth, bright and clean, crisp, compact, can be divided into two kinds of type double integral and packaged trays. Monolithic tray form complex, high cost, but the product quality is better. Many manufacturers use packaged tray, the tray type double integral divided into fluctuation two parts, injection molding respectively before assembly.
Logistics industry in our country belongs to the emerging industry, and the application of the plastic box make the development of logistics industry got faster. It reduce logistics of our country capital, expand foreign trade and economic resources conservation and maintenance of the ecological environment is the ideal of great significance. At present, in addition to the wide, consumption enterprise operation management level is advanced, ordinary material handling fee of the products up to 40% of the total capital.
From the application situation, plastic box is mainly used in stackable plastic pallets the warehouse and transport links between the handling operation. This product non-toxic tasteless, uv resistance, not easy to change color, smooth surface, easy to clean, heat preservation effect is good, not afraid fell to touch, can be used for life. Widely used in machinery, automobiles, home appliances, light industry, electronics industry, acid and alkali resistant, oil resistant, non-toxic tasteless, can be used for serving food, clean convenient, parts turnover, and neatly stacked, facilitate management.
And in practical application, the plastic box with a variety of logistics, containers and tools to complete the scene of the requirements. In today's logistics management is the enterprise more and plastic pallet box more attention, the plastic box help complete logistics container generalization, integration management, is the production and circulation enterprises are essential to the modern logistics management.
Finally a method is called extrusion molding in, that is, using equipment of extruder, head, extrusion as upper and lower panels with slats and as support in connection with the complex wing of i-section connecting plate, and then assembled. At the same time, with the emergence of wood plastic composite, promote the development of the extrusion molding in the plastic tray. This type of plastic tray has woodiness sense, water resistance, the advantages of the pest, but also saw, dig, nail.
