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. It has quite low permeability to gases and humidity increasing shelf-life of products.The preform moulding die (extrusion die, injection die) has been mentioned above. Due to high sustaining capability, it is ideal for storing carbonated products. It is unbreakable, tough and incredibly convenient for production and storage. It complies with most of the food materials and do not affect the physical appearance, taste or odor. Sparkling bottles with almost glass like finish can be produced using it. PET or PolyEthylene Terephthalate is a great material for producing pure, healthy and food grade containers. Since we are also manufacturer of outstanding quality bottles, Caps. We have expertise of creating preforms and blowing to make it a finished product. Aim Technologies (Dhimahi Pet Plast) is a leading designer and manufacturer for renowned brands of India and abroad. Preforms revolutionize PET manufacturing process and bring considerable benefit in cost, impact to the environment and operational efficiency and flexibility. All the Preforms are engineered to perfection and no compromise has been done on the quality of the PET Preform. We at Aim Technologies (Dhimahi Pet Plast ) are taking account of all the factors which are a big problem in blowing stage later on. There are various methods to form a Preform and there are many factors which affect it. Preforms play a very vital role in deciding the strength of the PET Bottle. These preforms are developed from premium grade virgin quality PET resins and can be ordered from us at a competitive price. Further, the offered preforms are developed in extremely hygienic environment with strict adherence to quality regulations. Specially developed with zero A level, the offered preforms become most suited for beverage applications. We are well known enterprise engaged in developing highly viable Transparent PET Preforms(Virgin). We Aim Technologies are Supplier of 18.35 grams Pet Preform for mineral water bottles of 1 Litter.
