The Ultimate Buying Guide for PET Blow Machine

Stretch Blow Moulding Machine of PET Bottle FST-12000 3

PET blow machine refers to the machine that blows PET bottles. The most simple explanation is that the finished PET bottles can be blown into bottles by certain technological means. The bottle blowing machine is convenient and fast, and has a large amount of formation. after it appeared, it replaced most of the manual bottle blowing and was adopted by most beverage enterprises. We also call it PET bottle blowing machine or PET bottle blow molding machine. PET bottles are widely used in food packaging, pure water and mineral water filling, fruit juice filling, soft drink filling and other fields. Its excellent economy has won very good market feedback. The birth of PET bottle blow machine has also greatly promoted the rapid development of the beverage and bottled water industry.

Most PET bottle blowing machines are two-step bottle blowing process, that is, plastic resin must be made into PET bottle preform before blowing. Nowadays, the commonly used material is PET, which is environmentally friendly plastic. The PET preform is heated to the softening state and placed in the open mold. After closing the mold, compressed air is injected into the preform immediately, so that the PET preform is inflated and clings to the inner wall of the mold. After cooling and demoulding, various PET empty bottles are obtained.


The PET preform is irradiated through an infrared high temperature lamp tube to heat and soften the body part of the preform. In order to maintain the shape of the bottle mouth, the preform neck does not need to be heated, so it needs a certain cooling device to cool it.

Blow bottle forming.

In this stage, the preheated bottle preform is placed in the blow mold, which is inflated under high pressure, and the bottle preform is blown into the required bottle.

Bottle blowing machines on the market are generally divided into fully automatic and semi-automatic. The fully automatic bottle blowing machine completes the two operations of bottle blowing together through the operation of the manipulator, eliminating the process of putting the preheated preform into the blowing mold. The rate of production is greatly accelerated, and of course the price is higher than that of semi-automatic ones.

How to choose the type of bottle blowing machine you need must also be the topic that everyone pays the most attention to. Generally speaking, choose the model of the bottle blowing machine according to the products you need. For different manufacturers, the general concern is the number of cavities, the size of the bottle volume, and the output per hour. It is critical to choose the model that meets your needs according to your own needs.

For 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. Different bottle sizes need separate bottle moulds to produce. Many customers think that one bottle blower and one mould can produce all bottle types, which is wrong.

Under normal circumstances, PET bottles less than 2L can be produced on the same bottle blowing machine.

300ml 2l bottle water production line

PET bottles of sizes ranging from one gallon to 15 liters need a separate high-capacity bottle blower.

3l 15l bottle water filling line

If it is a 5-gallon bottle used in the water dispenser, it is a different kind of bottle blowing machine.

5 Gallon filling line

After determining the bottle type, you can tell the manufacturer the production capacity you need (how many bottles per hour). The greater the production capacity of the machine, the higher the degree of automation and the higher the price.

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.

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

(1) The moving parts must be lubricated once before each shift is started. (manipulator, manipulator guide, opening and closing die guide).

(2) The arm swing can be added once every 3 to 4 days. The big chain and small chain of the heater can be used once a month. Always check whether the main engine reducer and heater reducer are short of oil. The main engine bearing can be added once every 3 months.

(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.

(4) Check whether the high pressure gas source, low pressure gas source, power supply and water source are normal.

(5) Check whether the emergency stop switch, safety door switch and protective device check whether the switch is normal.

(6) Check whether the heating head is in the preform and whether the preform is working normally. If the preform is not in place, the nut of the preform pressing device can be adjusted.

(7) Check whether the lamp tube is damaged or broken. It should be replaced in time.

(8) Check whether the pneumatic components are leaking and whether the action is sensitive.

(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.

(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).

According to the degree of automation, there are fully automatic PET bottle blowing machine and semi-automatic PET bottle blowing machine.

four cavity bottle mold

According to the number of mold cavities, it can be divided into two-cavity bottle blower, four-cavity bottle blow molding machine, six-cavity PET blowing equipment, 8-cavity stretch blow molding machine and so on.

The price of PET bottle blowing machine is related to many factors, such as bottle size, production capacity, degree of automation and so on.

In water bottling plants, juice bottling plants, PET bottle blowing machine is a very special existence. It cannot run independently and requires other auxiliary equipment to be connected together to complete the bottle blowing process.

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. The following figure is a schematic diagram of a conventional linear stretch bottle blowing machine system.

bottle blow molding system process

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 smallest semi-automatic PET bottle blowing system also requires a price of more than $10,000 (excluding packaging freight). If it is a high-speed rotary stretch blowing machine system, it requires an investment of millions of dollars.

Although 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.

Reduce production costs and increase the input-output ratio. In fact, when the market is good enough, you can quickly recoup the investment in bottle blowing machines and take the lead in the market.

As a China PET bottle blowing machine manufacturer, we are well aware of customers’ pain points and the most real needs of customers.
