Brief introduction to the development status of domestic blow molding machines Blow molding is a common method for manufacturing hollow thermoplastic products. The main products are tubular membranes and hollow containers. The blow molding machine can plasticize the preformed product by heating, and then enter the mold to blow into the mold. This method is mainly used for the production of high-speed and high-yield PET bottles and BOPP bottles, that is, two-step process; blow molding can also be combined with The injection molding process is combined into a blow-in-blowing machine, which is also a common method for producing containers in PET; the blow molding process can also be combined with the extrusion process, and the extrusion blow molding equipment can be adapted to a wider range, and the products that can be produced are also More abundant, the products include multi-layer composite film 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 processes are mainly used for forming PET and BOPP hollow containers. Both have their own characteristics and are widely used. The two-step method is more suitable for the production mode of concentrated production of preforms and dispersion bottles, and the one-step method is more suitable for online production of beverage companies. Therefore, at present, the main users of China's two-step equipment are professional PET bottle production plants, while the one-step equipment is mainly beverage manufacturers such as Master Kong and Wahaha.

The PET bottle blowing machine is divided into two types, rotary type and straight type, according to the conveying mode when the preform is heated. The rotary blow molding machine has high productivity, high speed, complicated design and high price. The automatic rotary blow molding machine of the automatic blow molding machine is the SBO series of SIDEL of France. The SBO24 type blow molding machine produces more than 20,000 bottles per hour. The typical representative of the linear blow molding machine is Japan's ASB and AOKI. In fact, this mechanical design is relatively simple, but the production will create a bottleneck, it is difficult to exceed 6000 bottles / 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 hot runner also determine the quality of the product.
At present, the injection-blowing equipment used in PET bottle production in China is basically the world of imported products, especially in the production of high-speed and large-volume products, domestic equipment can not compete. It is worth mentioning that there are few manufacturers that can produce large-capacity PET hot-fill bottle blowing machines. It seems that only ASB's multiple blowing process has achieved satisfactory results.
With the rise of the cold aseptic filling process, a new round of blow molding machine market battle will be opened. At present, Sipa's one-step blow molding machine has established 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 various materials such as PE, PS, PVC, PC, etc., and the application fields of the products are also wider. Three-quarters of the blow molded articles on the market are manufactured by extrusion blow molding. The extrusion method can produce a few milliliters of eye drops, and can process more than 1000L trays or tons of barrels.
At present, China's extrusion blown hollow container production equipment is fully satisfactory. For example, Yaqi's extrusion blow molding equipment has formed a sequence of equipment, which can produce blow molding containers of various specifications below 200L, and has developed an in-mold labeling extrusion blow molding machine, which is widely used in cosmetics and lubricant oil fields.
Wood Texture Car Wrap Film
The material is soft and flexible allowing it to conform to contours and bend easily. After applying the Vinyl Sheet, you simply trim the excess vinyl with a sharp blade or hobby knife (not included). What you have left is a customized look without the head aches and costs associated with painting.
COLORS AND PATTERNS MAY VARY FROM PICTURES AND VIDEOS. IT IS VERY HARD TO CAPTURE PICTURES OF THE VIVID COLORS, DIFFERENT SHADES, AND TEXTURES OF THE VINYL. WE RECOMMEND ORDERING A SAMPLE.
