Reduce production costs and increase the input-output ratio. If it is a high-speed rotary stretch blowing machine system, it requires an investment of millions of dollars.Īlthough it costs more to buy a PET blow molding system, you can control the quality and supply of the bottle, and you can connect it directly to the filling line through the air conveyor. The smallest semi-automatic PET bottle blowing system also requires a price of more than $10,000 (excluding packaging freight). The price of the whole PET bottle blowing machine system will be relatively expensive, accounting for a high proportion of the entire production line investment, which requires you to plan in advance. The following figure is a schematic diagram of a conventional linear stretch bottle blowing machine system. Rather than buying a bottle blowing machine, you are actually buying a PET bottle blowing system, which includes a bottle blowing machine, bottle preform heater, high pressure air compressor, high pressure air storage tank, water chiller, air cooling dryer, air filter, bottle blowing mold and connecting pipes, etc. It cannot run independently and requires other auxiliary equipment to be connected together to complete the bottle blowing process. In water bottling plants, juice bottling plants, PET bottle blowing machine is a very special existence. The price of PET bottle blowing machine is related to many factors, such as bottle size, production capacity, degree of automation and so on. (10) If there is anything abnormal in the electromechanical solenoid valve of the fully automatic bottle blowing machine, it should be cleaned in time (3.5 million per bottle blowing). (9) Check whether the triplet is abnormal air leakage, whether it is blocked, and whether the water storage capacity of the water cup is too full. (8) Check whether the pneumatic components are leaking and whether the action is sensitive. (7) Check whether the lamp tube is damaged or broken. If the preform is not in place, the nut of the preform pressing device can be adjusted. (6) Check whether the heating head is in the preform and whether the preform is working normally. (5) Check whether the emergency stop switch, safety door switch and protective device check whether the switch is normal. (4) Check whether the high pressure gas source, low pressure gas source, power supply and water source are normal. (3) Before production, check whether the moving parts are firm, whether the screws are loose and fall off, especially where the impact force is strong, and whether the belt transmission part is abnormal. The main engine bearing can be added once every 3 months. Always check whether the main engine reducer and heater reducer are short of oil. The big chain and small chain of the heater can be used once a month. (2) The arm swing can be added once every 3 to 4 days. (manipulator, manipulator guide, opening and closing die guide). (1) The moving parts must be lubricated once before each shift is started. If you need a stable, cost-effective PET bottle blowing machine, you can contact us and we will customize a solution according to your needs The PET bottle blowing machine accounts for a large proportion of the investment in the entire production line, so you need to prepare a sufficient budget. The greater the production capacity of the machine, the higher the degree of automation and the higher the price. If it is a 5-gallon bottle used in the water dispenser, it is a different kind of bottle blowing machine.Īfter determining the bottle type, you can tell the manufacturer the production capacity you need (how many bottles per hour). PET bottles of sizes ranging from one gallon to 15 liters need a separate high-capacity bottle blower. Under normal circumstances, PET bottles less than 2L can be produced on the same bottle blowing machine. Many customers think that one bottle blower and one mould can produce all bottle types, which is wrong. Different bottle sizes need separate bottle moulds to produce. It is critical to choose the model that meets your needs according to your own needs.įor example, suppose you want to buy a PET bottle blowing machine for your own water bottling plant, then you have to determine how many bottle sizes you have, such as 500ml, 1L, 1.5L, etc. For different manufacturers, the general concern is the number of cavities, the size of the bottle volume, and the output per hour. Generally speaking, choose the model of the bottle blowing machine according to the products you need.
