Reveals common problems and solutions in PET bottle embryo production
Hello everyone, today we will talk about a few common problems in PET bottle embryo production, and discuss how to solve them. As a leader in the industry, Heyan Molds has been committed to improving the quality of bottle embryo production.
1. Bottle rim problem
Have you ever noticed that some bottles have a thin bump around the top of the bottle? This is known as the "lip of the bottle". This is usually due to mold wear resulting in inaccurate closing, which in turn produces too much material during injection molding. The high-precision manufacturing and wear-resistant design of the joint research mold can effectively reduce this problem.
2. Poor sealing of bottle embryo mold
Poor sealing of the bottle embryo mold, whether it is the bottle blank mold or blow molding mold, may lead to product quality problems. As with the lip of the bottle, this is mainly due to mold wear. Choosing a die means choosing a longer die life and a more stable production quality.
3. Excess shoulder material
Sometimes the shoulder of the bottle will have a circle of excess material, like a ring set in there. This is usually caused by uneven heating rotation and uneven stretching of the material during blow molding. The precise design and efficient heating system of Heyan mold can ensure uniform heating and reduce such problems.
4. Impurities in the bottle
There are black spots, foreign bodies, unmelted particles and other impurities in the bottle, often because of improper material handling before injection molding. The strict material control and cleaning process of the joint research mold can ensure the purity of raw materials and reduce the generation of impurities.
5. Color problem
For colored bottles, the shade is very important. Too deep or too light color may be caused by abnormal mixing of the color mother machine or screw. The advanced color machine system and precise screw design of the joint research mold can ensure the stability and consistency of color.
6. Bottom deviation problem
Bottom deviation means that the injection point does not coincide with the blow molding center, resulting in uneven thickness around the bottle. This may be due to mold design, uneven heating, or an abnormal blow molding process. The precision design and optimization of the heating system can effectively reduce the bottom bias phenomenon.
7. Fluorescence problem
The fluorescence usually appears on the bottom of the bottle or on the shoulder, and it appears that some areas are gray and bright. This can be caused by thin bottle walls or excessive blowing pressure. The precise control and optimal design of the mold can reduce the occurrence of fluorescence phenomenon.
8. Bubbles inside the bottle
There are bubbles inside the bottle, usually because of insufficient drying, resulting in the plasticized material containing gas. The strict drying process and quality control of the mold can ensure that the material is fully dried and reduce the formation of bubbles.
9. Other common problems
In addition to the above problems, the bottle may also appear white, opaque, strengthening the ring warping and other phenomena. These problems can be related to the production process and material handling. The choice of the mold is to choose a more stable production process and higher product quality.

The use of blow molding plastic bottles in the food and beverage industry has been regulated to ensure they are safe for consumption. This is done through strict quality control measures, including testing for chemical contaminants and ensuring the bottles do not leach harmful substances into the contents. Additionally, manufacturers are encouraged to use food-grade plastic for blow molding plastic bottles.
In conclusion, blow molding plastic bottles are an efficient and cost-effective way of packaging products, making them popular in various industries. With the ability to customize shape and size, blow molding plastic bottles are an attractive option for manufacturers looking to stand out among their competitors. As technology advances, we can expect to see further improvements in this area, including enhanced safety measures and greener materials.
