How to Choose a PET Bottle Blowing Machine

PET bottle blowing machine is mainly used for PET plastic bottle blowing. It is completed by a series of actions such as feeding, heating, conveying, stretching, mold clamping, etc. In this process, the PET chain is bidirectionally extended, oriented, and arranged, thereby increasing the mechanical properties of the bottle wall, improving the tensile, tensile and impact strength.

Although stretching helps to increase strength, it should not be stretched too much. It is necessary to control the stretch blow ratio. Bottle blowing is performed between the glass transition temperature and the crystallization temperature. In this interval, PET shows a high elasticity and it is quickly blown and cooled to become a transparent bottle.

How to choose a PET bottle blowing machine:

1. Yield:

According to the requirements of its own production output, choose one-out two-, one-out four-parameter machines and buy the machine according to the factory parameters.

2. Whether it is hot-filled:

I don't know if your fruit and vegetable drinks need to be sterilized or something, but for hot-filled drinks, the bottle blowing machine needs a heat-resistant bottle blowing machine, this machine has special PET bottle Handle to prevent deformation during the filling process.

3. Price:

PET bottle blowing machine price varies because of many factors.

While choosing it, it’s better to compare between several suppliers.

4. After-sales service:

It is inevitable that some situations will occur in the running machine. Good suppliers have good after-sales service and follow-up parts update capabilities.

5. Air source:

The bottle blowing machine needs to be used with air source, because it contains pneumatic devices. I don't know if you already have an air compressor and buy a blow molding machine, or do you all need to buy it. The combination of the two is also important. It is necessary to meet each other, save insufficient air pressure, or excessive waste of resources cannot reach the goal of maximizing energy efficiency and saving costs.

Today, there are a lot of domestic manufacturers of blow molding machines. Selecting a fully automatic PET bottle blowing machine china manufacturer with a good brand based on the appropriate price of the blow molding machine should also be the key to consider.

For some large beverage, mineral water or cosmetics manufacturers, because of the large amount of packaging used, they are often integrated with the product filling. This type of blow molding machine should choose a fully automatic, high speed, stable and reliable blow molding bottle machine. Only such a blow molding machine will not affect other links in the later production process, affecting the overall production efficiency. For some small and medium-sized manufacturers, a semi-automatic, two-step blow molding machine can be considered. On the one hand, it can reduce the cost of the first purchase of the blow molding machine. Because the plastic bottles produced by the blow molding machine are hollow products, if they are stacked in large quantities, it will put a lot of pressure on storage. For some individual or family workshops, you can consider using a second-hand blow molding machine from the beginning. The price of this type of blow molding machine is relatively low. If you understand the parameters of various aspects before buying, there are still many cost-effective machines to choose.
