Plastic bucket is an indispensable household appliance in daily life. Many plastic bucket manufacturers' plastic buckets have the advantages of light weight, good strength, non-toxic and tasteless. It is suitable for the packaging of various salty liquid foods, condiments, medical and health products, wines, and fine chemical products. Therefore, it has been widely used.

Household plastic bucket is different from ordinary plastic bucket. Because of their different materials and forming processes, their uses and functions are also different. The injection molding time often mentioned in the process refers to the time required for the plastic melt to fill the mold cavity, excluding the auxiliary time such as mold opening and closing. Although the injection time is very short and has little effect on the molding cycle, the adjustment of the injection time plays an important role in the pressure control of the gate, runner and cavity.

In the production process of plastic bucket, the materials of rotary molding method are generally crushed into powder, melted and flowing in the thermal cycle. By virtue of the unique properties of its chemical crosslinking grades, these grades have good fluidity at one stage of the molding cycle, and then crosslink to form its excellent environmental stress cracking, toughness, wear resistance and weather resistance.

another In addition, the cost of rotational mold is low - for products of the same specification and size, the cost of rotational mold is about 1/3 to 1/4 of the cost of blow molding and injection molding mold, which is suitable for molding large plastic products; The edge strength of rotary molding products is good - rotary molding can achieve a product edge thickness greater than 5mm, completely solving the problem of thin edges of hollow products; In addition, the shape of rotoform products can be very complex, and the thickness can exceed 5 mm. Rotationally formed products can be filled with foamed materials to achieve thermal insulation without adjusting the mold. The wall thickness of rotational molding products can be adjusted freely (more than 2mm).

The injection time is far less than the cooling time, about 1/10-1/15 of the cooling time. This rule can be used as a basis for predicting the whole molding time of plastic parts. In the mold flow analysis, the injection time in the analysis result is equal to the injection time set in the process conditions, only when the melt is completely pushed into the cavity by rotating the screw. If the pressure holding switch of the screw occurs before filling the cavity, the analysis result will be greater than the setting of the process conditions.
