Typically, PET mold preforms are crafted using hot runner molds. These molds, along with the injection molding machine templates, are mounted between insulation plates, ideally with a thickness of 12mm, which are capable of enduring high pressures.
When it comes to PET plastic injection molds, their design is crucial. Adequate venting is essential to prevent localized overheating or shattering, but it's important to note that the exhaust port depth should not exceed 0.03mm to avoid the creation of burrs.
Furthermore, to ensure optimal performance, the mold gate should be positioned on thicker parts of the PET, avoiding melt injection issues. This strategic placement helps mitigate high flow resistance and rapid cooling, ensuring that the mold cavity is filled effectively.
Additionally, the mold gate's opening orientation can be directly opposed to the cavity wall or thick core. This configuration alters the flow direction and reduces the flow rate, enabling the melt to fill the cavity uniformly and preventing surface defects.
PET bottle mold is a type of mold used to create plastic bottles out of Polyethylene Terephthalate (PET) material. The PET bottle mold works by injecting molten plastic material into a hollow cavity, which takes the shape of the mold, eventually forming the desired plastic bottle.
There are several benefits of using PET bottle molds. Firstly, PET bottles are lightweight, durable, and shatter-resistant, making them a popular choice for packaging various food and beverage products. Additionally, PET is a recyclable material, which makes it an environmentally friendly option.
The mold design plays a crucial role in determining the shape and size of the plastic bottle. The mold can be customized to create bottles of different shapes, sizes, and capacities, making it a versatile option for manufacturers. Furthermore, the mold can also include additional features such as labeling and embossing, providing branding opportunities for businesses.
The PET bottle mold typically comprises two halves, referred to as the core and cavity. These halves fit together with precision, creating a seal that prevents the molten plastic from escaping. The molten plastic material is injected under high pressure into the mold through an injection gate, which is then cooled, solidified, and ejected from the mold as a finished product.
Overall, the PET bottle mold is an essential component in the production of plastic bottles. It is a cost-effective option that allows manufacturers to create bottles of various shapes and sizes. The widespread use of PET bottle molds has made it possible for consumers to enjoy their favorite beverages in lightweight and shatter-resistant bottles, while also contributing to a more sustainable environment.

What are the Conditions for PET Injection Molding Process ?
PET injection molding is a prevalent technology in plastics manufacturing, and achieving optimal results hinges on adhering to specific process conditions.
Drying Treatment
PET macromolecules contain lipid groups, making them hydrophilic. The pellets are highly sensitive to water at high temperatures. When the moisture content exceeds the limit, the molecular weight decreases during the injection molding process, leading to discoloration or brittleness in the final products. Therefore, it is crucial to dry the PET pellets before injection molding. The recommended drying temperature is between 100-120°C, with a drying time of 3-4 hours. Additionally, the use of recycled PET material should not exceed 25%.
Injection Molding Machine
PET has a short period of stability after melting and a high melt temperature. Therefore, it is essential to choose an injection molding machine with multiple temperature-controlled segments and minimal self-friction heat generation during plasticization. The actual weight of the injection-molded PET product, including the sprue material, should not be less than two-thirds of the machine's injection volume.
Cylinder Temperature
The molding temperature range for PET is narrow, and the temperature directly affects the product's performance. The cylinder temperature should be controlled between 240-280°C for standard PET and 250-290°C for glass fiber-reinforced PET, with a maximum limit of 300°C. The nozzle temperature should generally be 10-20°C lower than the cylinder temperature.
Mold Temperature
The mold temperature significantly impacts the cooling rate of the melt and its crystallinity. Different crystallinities result in varying performance characteristics of PET plastic parts. Typically, the mold temperature should be controlled between 100-140°C. For molding thin-walled plastic parts, a lower value can be used, while for thick-walled plastic parts, a higher value is recommended.
Injection Pressure
PET melt exhibits good fluidity and is easy to mold. Therefore, medium pressure is usually sufficient, ranging from 80-140 MPa for standard PET and 90-150 MPa for glass fiber-reinforced PET.
