Water lubricated air compressor pet bottle blowing air compressor purchase plan

The medium pressure air compressor produced by Grencklin Group is widely used in the PET bottle blowing industry. The compressed gas of the water-lubricated air compressor does not contain oil, and the bottle blowing is more in line with the requirements of food safety production.

PET is the most widely used beverage packaging material today. PET bottles originated in the early 1980 s. Because of its light weight, easy forming, low price, and easy mass production, it has developed rapidly with an unstoppable momentum since its inception. In just 20 years or so, it has developed into the world's most important form of beverage packaging. PET is not only widely used in the packaging of medicines, carbonated beverages, bottled water, condiments, cosmetics, liquor, dried fruit candies, edible oils, pesticides and detergents, but also specially processed special filling bottles can also be used in the packaging of juice and tea drinks.

PET material is how to make a plastic bottle?

It is roughly divided into two steps: injection molding and blow molding. First, the PET particles are melted at high temperature to make the preform. The preform is like a test tube with a bottle mouth. There is a protruding ring on the bottle mouth, which is called a supporting ring. This part is very important in the blow molding process. This supporting ring can be used to hold the preform. After blowing out the bottle, the filling machine also needs to fix the bottle by the supporting ring for filling.

The process of blow molding can be imagined as blowing a balloon. The heated preform is inserted into the mold, a metal rod is inserted into the preform, and high-pressure air is injected into the bottle instantly. The preform is blown up until the edge of the mold is stuck and a specified shape is formed. After demoulding, a plastic bottle is completed.

To blow up the test tube-shaped PET bottle blank instantly, high-pressure air is required to complete it. Therefore, the air compressor matched with it must be a medium and high-pressure series, and the recommended pressure is 3-4Mpa. If PET bottles are used for filling food, medicine, and beverages, there are higher requirements for air cleanliness-sterile, dust-free, and oil-free.

granklin water-lubricated air compressor uses pure water as the medium for lubricating, sealing and cooling the main engine of the air compressor head, which can ensure that the produced air does not contain a drop of oil. The air will pass through the air filter element before entering the compressor chamber to remove most of the dust. Higher sterility and dust-free requirements can also be completed by supporting post-processing equipment. The pressure of GW series medium pressure oil-free screw air compressor series can reach up to 4Mpa, and the displacement range covers 2.8m & sup3;/min-22m & sup3;/min, meeting the needs of most bottle blowing industries.

The safety of food and drugs is the most important point for every production enterprise. Whether it is the production process of food and drugs, or the filling and packaging process, every careful equipment selection is responsible for the customer. Because we are not only producers, but also users. Granklin will always adhere to the initial heart, do not forget the mission, and advocate more enterprises to use truly oil-free air compression equipment!
