Plastic bucket in the production process of the case

 

    Plastic bucket in the production process there are special circumstances, require special attention. For example: plastic barrels processing temperature control in the production of transparent plastic bucket attention points and so on. Well-known plastic bucket itself is very widely used, and the user of the quality of the product is relatively high, the same requires manufacturers in the production process to avoid unnecessary loopholes.

    Special circumstances 1, plastic barrels injection process to pay particular attention to its temperature control, too high or too low will not be completed plastic barrels injection: mold temperature a significant impact on the intrinsic properties of products and apparent quality. Mold temperature is decided whether the plastic crystalline, size and structure of products, performance requirements; cylinder temperature: injection molding process requires temperature control of cylinder temperature, nozzle temperature and mold temperature. The first two major impact plasticization temperature and flow, the latter mainly affect temperature plastic flow and cooling; nozzle temperature: nozzle temperature is usually slightly lower than the maximum temperature of a cylinder, which is to prevent the melt in the pass-through nozzle may occur, "drooling phenomenon."

    Special Case 2, transparent plastic bucket production on the one hand, because high transmittance of transparent plastic, so it requires quality plastic surface to be strict, can not have any markings, whitening, pores, black spots, fog faint discoloration gloss poor and other defects, so the entire injection molding process for raw materials, equipment, molds, and even product design, requirements are very high. On the other hand, because the transparent plastic of high melting point, poor mobility so generally need to make minor adjustments in the injection pressure, high temperature machines, injection speed and other parameters, so that both full of plastic injection molding, and will not produce stress, thus avoiding product deformation and cracking.
