![]() The product cavity should be polished for a high gloss, high transparency, and other special requirements.Ĭ. The container handle is generally set on the parting surface.ī cavity surface: low blowing pressure, low moulding temperature, plastic will not enter the trough of microscopic unevenness (roughness), relatively rough profile, not only will not affect the surface state of the product but also facilitate exhaust. For products with complex shapes, the parting surface can be a curved surface or a combination of multiple planes. For example, the extrusion blow mould has a blank opening and a remaining material slot the air inlet rod of the stretch blow mould is controllable and expandable, and so on.Ī Parting surface: usually, the plane passes through the most significant part of the profile of the product section. The specific structure of the blow mould varies with the design of the plastic part and the blowing method of the preform type. In addition, similar to other two-half cavity moulds such as injection moulds, compression molds, and transfer moulds, the blow mould also has a mould clamping guide positioning mechanism, a cooling system, and an exhaust system. This is a hallmark feature shared by blow moulds. There is only a cavity (regardless of unevenness) of the outer shape of the moulded product and no core there is an air inlet between the two mould halves Rod or intake needle. Therefore, the blow moulder’s moulds are mostly two halves or multiple moulds (when side parting is required). Only the blow moulder mould’s external structure size is limited, and the internal structure size depends on the shape. Here we mainly discuss the narrow sense.īlow molding process mould-blow molding mold is referred to as blow mould.As mentioned above, the hollow product is formed by injecting compressed air into the high-temperature preform and pressing it against the surface of the mould cavity by the air pressure in the preform. Yugong PET preform injection machine can make salad oil preforms, beverage preforms, wide-mouth preforms, cosmetic preforms, medicine preforms, three-gallon, five-gallon preforms, and other preforms.The preform moulding die (extrusion die, injection die) has been mentioned above.
