6 selection criteria for automatic blow molding machines

The selection criteria for automatic blow molding machines are

1. Output: According to the production output requirements, choose a machine with parameters such as one output two, one output four, etc., and buy according to the factory parameters. At present, the output of two-in-one automatic blow moulding machines produced by blow making machine manufacturers with better technology in the market is about 2,500 sets, and the output of automatic molding making machines is about 4,500 sets.
2. Stability: The stability of the equipment is very important. Now the blowing mold machine works for a long time, usually not less than 10 hours. The equipment runs unstable for a long time, which affects the normal production of the enterprise.
3. Whether it is hot-filled: For hot-filled beverages, the blow molding equipment needs a heat-resistant blow molding product. This machine has special treatment for the bottle to prevent deformation during the filling process.
4. Price: Price is very important, but I firmly believe that one, one price, one product.
5. After-sales service: During the operation of the machine, there will inevitably be some situations, the after-sales service is thoughtful, and the ability to update subsequent parts is strong.
6. Air source: All blow molding machines need to be equipped with an air source, because the inside is a pneumatic device. The combination of the air compressor and the bottle blowing machine is very important. They must satisfy each other, and the lack of air pressure or the waste of excess resources cannot achieve the goal of high energy saving ratio and cost saving.

The principle of jerry can blow moulding machine

After entering the extruder barrel together with the hopper, as the screw rotates, the thread is forced to push it towards the direction of the machine head. Due to the resistance of the filter screen at the machine head, the splitter plate and the die of the machine head, and the capacity between the threads gradually decreases, the advancing material is subjected to great resistance, and at the same time is heated by the heat transferred by the material cylinder; on the other hand, when the plastic When subjected to compression, shearing, stirring and other forces during motion, the friction between the material cylinder and the screw and the friction between the plastic molecules will generate a lot of heat.

As the temperature of the plastic in the cylinder increases, its physical state gradually changes from a glass state to a highly elastic state, and finally to a viscous flow state, and is further fully plasticized. Due to the continuous rotation of the screw, the plastic is extruded from the mold under equal pressure, which is called a certain shape of the plastic product. After cooling, the extrusion work is done.

Production demand of blow molded products

First look at the type of product you want to make, and choose a plastic blow molding machine according to the choice of plastic products. For example, let’s take a large blow molding machine as an example! Plastic molding machines can produce products: barrels, water tanks, barricades, pallets, septic tanks, etc., considering how many L-volume plastic products they need to produce, choose different machines according to different production products, because in the design and production of machines, manufacturers The investment cost is different, and the natural price is different!

Blow molding machine manufacturers

It is more important to purchase a fully automatic blow molding machine manufacturer. After determining the product, you need to communicate with the manufacturer and compare with multiple manufacturers when choosing a manufacturer. It depends on the qualification and technical team of the manufacturer. For example, when choosing a large blow molding making machine, the requirements for the manufacturer are very high. At the same time, blowing molding machine accessories are also very important. When you get a quotation, you should ask whether it is the bare machine price of the blow molding machine or the price of the complete blow moulding machine equipment. When consulting the manufacturer, the basic requirements of product type, product production capacity and production consumption should be communicated with the manufacturer in detail.
