Technological Development of Blow Molding Machine
The PET bottle blowing machine is divided into two kinds of rotary and linear according to the preform heating mode. Rotary blow molding machine capacity, high speed, complex design, the price is also higher. The typical rotary blow molding machine is the French SIDEL SBO series. Our SBO24 blow molding machine produces more than 20,000 bottles per hour; the linear blow molding machine is a typical representative of Japan's ASB and Aoki. Generally speaking, this machine design is relatively Simple, but the production will form a bottleneck and it is difficult to exceed 6000 bottles per hour. Temperature control is directly related to plasticization uniformity, and is the key to the success of blow molding products. The design and precision of the mold and heat flow also determine the quality of the product. China's current basic equipment for PET blow molding and injection production is imported from the world, especially in high-speed and mass production, domestic equipment cannot compete. It is worth mentioning that, among the manufacturers of blow molding machines capable of producing high-volume PET hot-fill bottles, it seems that only ASB has achieved satisfactory results with the repeated blow molding process. With the rise of aseptic cold filling technology, a new round of battle and blow molding machine market will be opened. Now the one-step blow molding machine in the west has a foothold in Beijing Huiyuan Juice Factory, but this does not mean that the two-step blow molding machine has no chance. The material of extrusion blow hollow container production equipment is more flexible, it can produce PE, PS, PVC, PC containers, various materials, such as product application fields are also more extensive. Three-quarters of blow molded products on the market are extrusion blow molded. The crowded blow method can produce ophthalmic bottles of a few milliliters and can handle more than 1000 l trays or ton barrels. At present, China's crowded production equipment for blowing hollow containers can fully meet the needs. Take Yaqi as an example, the company's crowded blowing equipment has formed a series, which can produce various blow molding containers under 200 l, and develop mold label extrusion blow molding machines. The products are widely used in cosmetics and lubricants, research, etc. Currently, China's development of extrusion and blowing equipment is not perfect, especially some equipment and various compound functions cannot be produced, such as widely used in liquid medicine packaging bottles, filling and sealing equipment.
