Why is the weight of the bottle blowing machine unstable?
A blow molding machine is an empty container equipment that mainly uses the blow molding process to make plastic particles into containers. The more common machine types include hollow extrusion blow molding machines for one-step molding of PP and PE, injection stretch blow molding machines for secondary molding of PET, PC or PP, and newly developed multi-layer hollow extrusion blow molding and stretch blow molding.
At present, most blow molding machines are still two-step blow molding machines, that is, the plastic raw materials are first made into bottle blanks, and then blown. Environmentally friendly plastics made of PET are commonly used now, that is, blow molding machines. Blow molding machines are a type of blow molding machine, that is, hydraulic blow molding machines, which use the wind force blown by the machine to blow the plastic body to a certain shape of mold cavity after the liquid plastic is sprayed out to make a product.
Usually, when producing fully automatic blow molding machines, the product weight is unstable and the product weight exceeds the specified deviation. The characteristic of unstable weight is that the water outlet material at the bottom of the bottle is of different lengths. In severe cases, the product cannot be blown into shape due to insufficient length of the material pipe. The main reasons for unstable weight are as follows:

Some precautions for blow molding machines when making plastic bottles
When people use various plastic products and equipment in life, especially plastic bottles, they not only have good performance characteristics, but also are easy to use. Compared with glass bottles, they are not only small in size and light in weight, but also will not break, etc., so they are widely used by people and widely used in life or other fields. Most of these plastic bottles are made by bottle blowing machines. Bottle blowing machines are mainly a kind of equipment that makes plastic particles into hollow containers through the blow molding process. Therefore, it is not only simple to use and easy to operate, but also saves more time. The following are the precautions before using the bottle blowing machine:

Solution to the problem of unformed bottle bottoms blown out by bottle blowing machines
The bottle blowing machine is mainly used to blow bottles on preforms. Most users report that the bottle bottom of the bottle blowing machine is not formed. There are many reasons for the unformed bottle bottom. Yucheng bottle blowing machine manufacturer shares with you the reasons and solutions for the unformed bottle bottom.
1. Reasons for bottle bottom heating
At present, most automatic pet bottle blowing machines are heated by infrared lamps. The heating box is divided into several independent areas, and the temperature is independently controlled. If the temperature is not enough or the heating is too low, the bottom of the blown bottle will not be formed.
Solution: Adjust the bottle bottom to the appropriate bottle bottom heating temperature. For specific temperature adjustment, please consult the pet bottle blowing machine manufacturer after-sales.

How to choose a bottle blowing machine
The market of bottle blowing machine industry is vast, and all kinds of bottles needed in daily life are made by bottle blowing machine. With the continuous advancement of science and technology, bottle blowing machine is characterized by green environmental protection, low price, brand sales, excellent and high energy. How to develop the bottle blowing machine industry around the subject of "safety, health and environmental protection" is an urgent problem that all manufacturers need to solve. Manufacturers who go against the mainstream direction will eventually be eliminated by the gradually improved market competition system. Therefore, domestic related enterprises should actively follow the mainstream development of the industry and develop more products that customers need, so that enterprises can develop well.

Reasonable selection method of bottle blowing machine
With the continuous improvement of people's living standards, people often use many different bottles in their lives. Take some beverage bottles as an example. They are not only convenient for people to carry, but also very convenient to use. These bottles are mainly made by bottle blowing machines. They mainly use various plastic particles to soften and convert them into liquids, and then blow them into bottles of different shapes according to different molds, which brings certain benefits to people's use in life. So, how should people choose a suitable bottle blowing machine?

Common technical problems of PET bottle blowing machine
The blow molding process is a bidirectional stretching process, during which the PET chain is bidirectionally extended, oriented and arranged, thereby increasing the mechanical properties of the bottle wall, improving the tensile, tensile and impact strengths, and having good air tightness. Although stretching helps to improve strength, it should not be overstretched. The stretch-blow ratio should be well controlled; the radial ratio should not exceed 3.5-4.2, and the axial ratio should not exceed 2.8-3.1. The wall thickness of the preform should not exceed 4.5mm.
