Pet Fully Automatic Stretch Blow Molding Machine

PET fully automatic stretch blow molding machine, the injection molding machine is divided into plunger injection molding machine and screw injection molding machine. According to the transmission mode of the machine, it can be divided into hydraulic, mechanical and hydraulic mechanical (connecting rod) type. According to the operation mode, it can be divided into automatic, semi-automatic and manual injection molding machines.

(1) Horizontal injection molding machine: This is the most common type. The mold part and the injection molded part are on the same horizontal centerline, and the mold is opened in the horizontal direction. Its characteristics are: short body, easy operation and maintenance, low center of gravity, relatively stable installation. After ejection, it automatically descends by gravity, realizing fully automatic operation. At present, most of the injection molding machines on the market use this model.

(2) Vertical injection molding machine: The mold part and the injection molded part are on the same vertical centerline, and the mold is opened in the vertical direction. Therefore, the area is small, the insert is easy to place, the mold is easy to load and unload, and the hopper can be fed evenly. However, it is not easy to automatically pull down on the top of the product, it must be operated manually, and it is not easy to realize automatic operation. This machine is suitable for small vertical injection molding machines, generally 60 tons (60 tons is the clamping force), and is widely used in the following injection molding machines, large and medium applications.

(3) Angle injection molding machine: its injection direction and mold interface are on the same surface. It is especially suitable for the processing of flat parts that do not allow door printing. Its area is smaller than that of a horizontal injection molding machine, but the insertion on the mold tends to drop. This injection molding machine should be used on small machines.

(4) Multi-mode phono injection molding machine: It is a dedicated injection molding machine for multiple operations. Its characteristic is that the mold closing device adopts a turntable structure, and the mold rotates around the rotation axis. This type of injection molding machine pet full-automatic stretch blow molding machine can make full use of the injection device, shorten the production cycle, and improve the production capacity of the machine. Therefore, it is particularly suitable for producing a large number of products that require long-term cooling or more More auxiliary time because of the insertion position. However, due to the large and complex model system, the clamping force of the clamping device is often small, so injection molding machines are used more in the production of plastic shoe soles and other products.

Ordinary injection molding machines include injection molding machines, clamping devices, hydraulic systems and electrical control systems. The basic requirements of injection molding are pet full-automatic stretch blow molding machine and injection molding. PET fully automatic stretch blow molding machine is the prerequisite for the realization and guarantee of product quality. In order to meet the molding requirements, injection must ensure sufficient pressure and speed. At the same time, due to the high injection pressure, the pressure in the mold cavity is very high (the average pressure of the mold cavity is usually between 20-45MPa), so there must be sufficient clamping force. It can be seen that the injection device and the clamping device are the key components of the injection molding machine.
