The problems associated with compressed air in PET blow molding are mostly related to cleanliness. This is especially important, because the high-pressure air that is used in the process comes into contact with beverages and beverage containers. For this reason, compressed air dryers are common and sub-micronic filters are often placed on the air entry.
Stretch blowing
Stretch blowing with PET plastic blow molds is a process that uses PET plastic as a base material to produce plastic parts. The material is a self-leveling plastic, which makes it a good choice for blow molds. When PET is stretched, it will remain stable in sections, unlike other thermoplastic materials. As a result, the blown parts will have equal tensile properties throughout their entire length.
To start the process, the raw material is fed into the injection stretch blow molding machine. It is heated in the barrel to a temperature of approximately 280 degrees Celsius. The plastic molten material is then injected under high pressure into the blow mold, creating the preform. The preform is then cooled, and the molten plastic is then demolded. It is then moved to a stretch blow moulding machine, where it is formed into the desired shape.
Injection molding
When looking to buy a plastic injection mold, consider choosing one that is made from PET plastic. This lightweight thermoplastic exhibits excellent thermal performance and dimensional stability. If you're looking for an ideal injection mold for a pet product, you'll want to work with a company that specializes in this type of plastic. 
PET is an aromatic polyester that is made by polymerizing terephthalic acid, dimethyl ester terephthalic acid, and ethylene glycol. It has a crystallization temperature between 120 degrees and 220 degrees.
pet plastic blow molds are a reliable investment for manufacturers. The Low Pressure Base model is two times more expensive than standard mold bases, but offers a number of advantages. These benefits include respecting original mold base shape, reducing stress cracking risks, and increasing mechanical performance. In addition, Low Pressure Bases are suitable for applications involving high-temperatures.
developed by in 2013, is another alternative to standard blow mold machines. It contains multiple vents within its ribs, which improves the efficiency of the blow molding process. This design is especially beneficial for high-speed production.plastic blow molds are used to produce plastic bottles in various shapes and sizes. These molds can also be used for other products, including oil cans and larger plastic containers. However, these molds are not cost-effective for the production of plastic bottles with handles. Therefore, manufacturers are continuously trying to find new ways to produce PET bottles that have handles.
Polyethylene is the most common blow molding material because of its desirable properties. It is easy to process, tough, flexible at low temperatures, odor-free, and toxin-free. It also offers excellent water barrier and electrical insulation properties, as well as low cost. LDPE is available in different grades.
When sourcing EVA pet plastic blow molds, it is important to consider the quality and material of your product. PET plastic is a durable material that can be shaped into unique, sophisticated shapes. It is used in various industries, including construction elements, automotive parts, and jugueteria. Using this material in production will create products that your customers will notice.
The process of making PET bottles involves two stages: first, the preforma is injected and tempered by thermal sensors. Once this is done, the material is pulled into the mould. The second step is the blowing process. This method produces a container with a low density that is durable and able to withstand pressure and shock.
