Product Description
Haichen automatic pet preform water bottle injection moulding machine
Preforms are made by PET injection molding machine. Beverage bottles, mineral water bottles, oil bottles, cosmetic bottles, plastic packaging boxes and so on, which are often seen in daily life, are made of preform blow molding.
What is pet preform manufacturing process?
Step1: Designing and manufacturing the preform mold
Step2: Injecting the plastic into the preform mold
Step3: Cooling the preform mold
Step4: Blowing preforms into bottles
Step5: Testing for PET bottles
Step1: Designing and manufacturing the preform mold
1. The first step in the design and production of a mold is to define the size of the neck of the preform, the weight and the output each day. With this information in hand, we will design and manufacture the injection mold according to the specific situation.
After the plastic is injected and fills the preform mold cavities, the product is cooled and shaped inside the mold. After cooling, the preforms are hard enough to be ejected from the mold.
However, the point to note here is that if the cooling effect is not good, the preforms will appear to be whitened. Because if the injection pressure is small, low injection speed, the first injection failed to fill the cavity, the first injection of the material flow front will be because of poor contact with the mold wall so that the temperature does not fall below the glass transition temperature, thus forming a large number of nuclei.
Step4: Blowing preforms into bottles
The process of blowing the preforms made by the injection molding machine into bottles is called blow molding.
Place the preform in a blow mould. Inject compressed air into the preform to inflate it until it is close to the cavity wall, and maintain the blowing pressure until the bottle cools. The plastic bottles are then removed after cooling.
2. After the customer has negotiated the product information of the preform, our designers start to design the molds, and after the molds are completely designed, we start to manufacture them.
3. After the molds are made, we test them thoroughly. Like check cooling system, geometry, surface roughness, common indentations, etc.
Step2: Injecting the plastic into the preform mold
Before making plastic bottles, the preform is produced using an injection molding process (injection molding machine). Once the plastic is molten, a screw mechanism injects the molten PET plastic into a preform cavity in the shape of a preform. PET preforms are much more compact than fully molded bottles.

Once the plastic is molten, a screw mechanism injects the molten PET plastic into a preform cavity in the shape of a preform. PET preforms are much more compact than fully molded bottles.

Place the preform in a blow mould. Inject compressed air into the preform to inflate it until it is close to the cavity wall, and maintain the blowing pressure until the bottle cools. The plastic bottles are then removed after cooling.
Rigorous testing of PET bottles on the production line is the final step before packaging to ensure compliance with industry standards. Tests include: impact test, pressure test, permeability test, transparency check.
