Blow molding machine purchase precautions
Blow molding machines are mainly used to blow preforms into finished bottles. Domestic blow molding machines can be divided into pet blow molding machines and other plastic blow molding machines according to the different plastic materials. There is no unified specification for domestic blow molding machines, and the technical level is also uneven. What should I pay attention to when using a blow molding machine? 1. Output When purchasing a blow molding machine, attention should be paid to the actual output of the blow molding machine. In the blow molding machine industry, the output of the blow molding machine can be divided into theoretical output and actual production output. Most manufacturers falsely report the theoretical output, and the output cannot reach the actual production use. In addition, pay attention to the stable output of the blow molding machine. Some manufacturers open the machine at a high rate during the test machine. After one month, the blow molding machine equipment cannot bear the high load, and the failure rate increases. 2. Stability The stability of the blow molding machine is the core factor in choosing a blow molding machine. Whether the blow molding machine can stabilize the production directly affects the production and profit of the enterprise. 3. Bottle blowing process There is no unified standard in the blow molding machine industry itself, and the design institutions are similar, but the core technology is quite different. The blowing process is related to the design organization, technical ability and process accuracy of the blowing machine. For example, most machines in Huangyan area have no problem blowing 18 grams of preforms. When blowing 13 grams of preforms, other blowing problems will occur, such as bottle bursting. 4. After-sales service After-sales service is also an important factor that should be considered when choosing a blow molding machine manufacturer. The principle of proximity is generally adopted, but the above three principles should be given priority. Otherwise, the equipment cannot be produced stably, and the after-sales service is not good either. However, a pain point in the blow molding machine industry is also after-sales service. Some manufacturers promise after-sales service, but the after-sales service is delayed. The after-sales service is perfect, and at the same time, the cancellation or replacement of wearing parts has been considered in advance when designing the blow molding machine, so as to reduce the failure points of the blow molding machine. 5. Energy consumption and after-sale maintenance cost The production cost of the enterprise directly determines the final profit and sustainable development of the enterprise. When purchasing a blow molding machine, it is also necessary to consider the energy consumption and after-sales maintenance cost of the blow molding machine. After the blow molding machine of some domestic manufacturers has passed the warranty period, the maintenance cost of parts and components is high, which increases the production cost. The blow molding machine equipment of individual manufacturers The maintenance cost is 30,000-50,000 yuan/year. Summary: The above points are the precautions for users when purchasing a blow molding machine. When purchasing a blow molding machine, users should not only pay attention to the price of the blow molding machine, but also pay attention to the output, stability, blowing technology, after-sales service, maintenance costs.
