Blow is the manufacture of hollow thermoplastic products commonly used method, the main product is the hollow tube membrane and the container. Blow molding machine can be heated to pre-Molded plastics, and then into the mold, Blow molding, this method is mainly used for high speed BOPP production of PET bottles and bottle production, that is, two-step process; blow molding and injection molding can also be technology combined into one injection stretch blow machine, and this is production of PET containers used in the method; blow molding process can also be combined with the extrusion process, extrusion blow molding equipment to adapt to? around more widely, can produce more products In order to enrich the product, including multi-layer composite films and various types of polyolefin hollow container, widely used in food, Medicine And cosmetic industry.
Hollow container forming machine
One-step and two step blow molding process, mainly for PET and BOPP molding hollow containers. Two different characteristics, are widely used. Two-step method is more suitable for concentrated production of preforms, bottles * distributed blowing bottle factory production model; and one-step device more suitable Beverages Online production company. Therefore, China is the main users of two-step devices such as purple river, in such a rich professional PET bottle production plant, and equipment was mainly one-step Master Kong , Such a beverage manufacturer Wahaha.
PET bottle blow molding machine heated by the transmission mode is divided into two kinds of rotary and linear. Rotary blow molding machine production capacity, high speed, design complexity, and higher prices. A typical rotary blowing machine is the French SIDEL SBO series, its SBO24 type blow molding machine production reached more than 20,000 bottles per hour, China's Tech-Long has successfully developed a rotary blow molding machine, the production rate per hour more than 8,000 bottles; linear blow molding machine is typical of Japan's ASB and AOKI, in general, this mechanical design is relatively simple, but will yield the bottlenecks, it is difficult more than 6,000 bottles / hour. Hong Kong Central, Hong Bao Jia Machinery Factory of Dongguan Development BOPP bottle blowing machine, too? With linear design.
Temperature control and uniformity are directly related to plastics, blow molding products is the key to success. Mold and hot runner design and precision, also decided the merits of product quality.
PET bottles currently produced in China for injection stretch blow equipment is basically dominated by imported products, especially in the high-speed and large volume production, the domestic equipment can not match. It is worth mentioning that, at present able to produce large-capacity hot-fill PET bottle blowing machine manufacturers rarely, it seems that only ASB multiple blowing process with satisfactory results.
Cold aseptic filling technology with the rise of a new round of blow molding machine market in turn opened the battle. The current one-step blowing machine SIPA has been in Beijing Huiyuan Fruit juice stand firm, it does not mean two-step method of blow molding machine will be no opportunity.
Extrusion blow hollow container production equipment adaptable to the materials, can produce PE, PS, PVC, PC and other materials in the containers, the product applications are wider. Market 3 / 4 by extrusion blow molding blow molding manufacturing. Extrusion blow method can produce a few milliliters of eye drops bottle, also can process more than 1000L Tray Or tons of barrels. China Extrusion Blow
current container production equipment has been fully meet the need. For example, extrusion blow molding equipment Akei equipment has been formed sequence, can produce all kinds of blow molding the following 200L containers, and developed in-mold labeling extrusion blow molding machine, the product is widely used in cosmetics and lubricants and oil fields. Another example Shantou Jinming Plastics Equipment Co., Ltd. and Shaanxi Qinchuan development of large capacity blow molding equipment has already occupied most of the domestic market.
However, the current development of China's extrusion blow equipment from the function is still not perfect, especially with a variety of complex features facilities can not produce, such as widely used in liquid pharmaceutical packaging bottle?? Filling?? Sealing three in one device.
Multilayer film production equipment
Extrusion blowing production Plastic Film is produced by blow molding process to another category of products. I am an expert from China Manufacturers, usually analyzes all kind of industries situation, such as digital security camera systems , remote control digital camera.
