How do blow molding machine
manufacturers seize the international market? Blow molding can also be combined with injection molding process to become an injection stretch blow integrated machine, which is also a common method for producing PET containers; blow molding process can also be combined with extrusion process. The scope of application of plastic equipment is wider, and the products that can be produced are also more abundant. Products include multi-layer composite films and various polyolefin hollow containers, which are widely used in food, medicine and cosmetics industries. Hollow container forming machine, one-step and two-step blow molding process, mainly used for PET and BOPP hollow container molding. Both have their own characteristics and are widely used. The two-step method is more suitable for the * bottle factory production mode of centralized production of preforms and dispersed blown bottles; and the one-step method is more suitable for the online production of beverage companies. Therefore, the main users of the two-step equipment in China are professional PET bottle manufacturers like Zijiang and Zhongfu, while the one-step equipment is mainly beverage manufacturers such as Master Kong and Wahaha. �The PET blow molding machine is divided into two types: rotary type and linear type according to the conveying mode when the preform is heated. Rotary blow molding machine has high production capacity, high speed, complicated design and high price. A typical rotary blow molding machine is the SBO series of French SIDEL. Its SBO24 blow molding machine has an output of more than 20,000 bottles per hour. At present, Tech-Long in China has also successfully developed a rotary blow molding machine with a production speed of more than 20,000 bottles per hour. More than 8000 bottles per hour; the typical representatives of linear blow molding machines are Japan's ASB and AOKI. Generally speaking, this kind of mechanical design is relatively simple, but the output will form a bottleneck, and it is difficult to exceed 6000 bottles per hour. The BOPP bottle blowing machine developed by Hong Kong Huanbao Group Dongguan Hongjia Machinery Factory also adopts a linear design. �Temperature control is directly related to the uniformity of plasticization, which is the key to the success or failure of blow molded products. The design and accuracy of the mold and hot runner also determine the quality of the product. �At present, China's injection stretch blowing equipment for the production of PET bottles is basically the world of imported products, especially in the production of high-speed and large-volume products, domestic equipment is still unable to compete. It is worth mentioning that there are few manufacturers that can produce large-capacity PET hot-fill bottle blow molding machines. It seems that only ASB's multiple blow molding process has achieved satisfactory results. �With the rise of cold aseptic filling technology, a new round of battle for the bottle blowing machine market will start again. At present, SIPA's one-step blow molding machine has gained a firm foothold in Beijing Huiyuan Juice Factory, but it does not mean that the two-step blow molding machine has no chance. �The extrusion blown hollow container production equipment is more adaptable to materials, and can produce containers of PE, PS, PVC, PC and other materials, and the product application field is also wider. 3/4 of the blow molded products on the market are manufactured by extrusion blow molding. The squeeze blowing method can produce eye drop bottles of several milliliters, and can also process pallets or ton barrels of more than 1000L. �At present, China's extrusion blown hollow container production equipment can fully meet the needs. For example, Akei’s extrusion and blowing equipment has formed an equipment sequence that can produce blow-molded containers of various specifications below 200L, and has developed an in-mold labeling extrusion-blow molding machine, which is widely used in cosmetics and lubricating oils. Another example is the large-volume blow molding equipment developed by Shantou Jinming Plastic Equipment Co., Ltd. and Shaanxi Qinchuan has already occupied most of the domestic market. �However, the current extrusion and blowing equipment developed in China is not fully functional, especially some equipment with multiple composite functions cannot be produced, such as the bottle-filling-sealing triple combination which is widely used in liquid medicine packaging. One device. �Multilayer composite film production equipment� Plastic film produced by extrusion blow molding is another major category of products produced by the blow molding process. At present, about 40% of plastic packaging films in developed countries are multi-layer co-extruded films produced by extrusion blowing, and the proportion in China is slightly lower. In the past, the production of composite films in China mostly used the dry or wet composite process of single-layer films, but the products were gradually replaced by multi-layer co-extruded films due to unstable quality, poor hygiene using adhesives, and high costs. �Multi-layer co-extrusion compounding process is to use multiple extruders to form a new type of functional film through a special die in the molten state of the material. It can be made into a multi-layer, multi-layer and multi-layer film with only one processing procedure. The functional composite film can save about 30% of the production cost compared with other composite processes. This kind of film can be configured with different components according to user requirements to meet different barrier requirements and cost requirements. �Before the 1990s, China mostly used rotary heads to produce co-extruded films with two to three layers. However, with the development, three-layer packaging films gradually gave way to five-layer or even seven-layer films. Accompanying this process and catalyzing this process is the development of domestic multilayer composite blown film equipment. At present, a number of equipment manufacturers represented by Shantou Jinming Plastic Equipment Co., Ltd. and Kunshan Xinzhong Machinery have emerged in China, capable of producing 3-layer, 5-layer, 7-layer or even 9-layer co-extruded film production equipment. �Multi-layer co-extrusion blown film production equipment has many key technologies, and the die is the most important one. ?Additional die is the most commonly used die, which has the advantages of short runner, free combination of layers, and independent temperature control. The production of this type of die has formed some well-known professional manufacturers, regardless of whether it is imported or domestic production equipment, most of them need to introduce die.
