properties of pet plastic bottle mould
PET preform mould,preform mould design and price from China.
PET preform mould PET, also called poly ethylene terephthalate, is also known as polyester.At present, the most used kind is PET-GF; it is mainly for bottle PET preform manufacturing. The rheological property of PET is better in molten state, and the pressure effect on the viscosity is greater than that of temperature.
problem and solution about PET injection molding
PET material is usuallly used for injection molding for plastic bottle preform,such as mineral water bottle,coca-cola bottle,juice bottle,etc. Characteristics of PET raw materials Excellent transparency of over 90%, excellent surface gloss and a glassy appearance. good aroma and air tightness.

PET chemical name is Polyterephthalate alcohol ester, also known as polyester. At present, the most used by customers is the GF-PET, mainly for the bottle preform. The rheological property of PET is better in the melting state, and the influence of pressure on the viscosity is larger than that of the temperature.
Properties of rPET-containing bottles | Food Packaging Forum
Properties of rPET-containing bottles. Scientists examine effects of recycled PET (rPET) on bottles’ properties, propose generic model to calculate acceptable rPET content for different scenarios; bottles from mono-collection systems have less particle contamination, more favorable optical properties, lower accumulation of contaminants, and therefore recommended to allow higher recycled content
What is PET blowing moulding & PET preform moulding.
Because PET (polyethylene terephthalate) has good mechanical properties, heat-resistant filling, and re-use, it is widely used: PET plastics are light in weight, high in transparency, resistant to impact and easy to break. They also prevent carbon dioxide gas and keep the soda air.
How to design PET preform mould Plastic mold,custom plastic.
A PET preform mould may be defined as a form for shaping a plastic material ”PET” into a finished product-here is PET preform. PET preform moulds are made of plain carbon steel or of alloy steels, and are hardened to provide compressive strength and hard surfaces to take and maintain a high polish under severe wearing conditions.
Properties of PET What is PET Plastic? Polyethylene terephthalate (PET or PETE) is a general-purpose thermoplastic polymer which belongs to the polyester family of polymers. Polyester resins are known for their excellent combination of properties such as mechanical, thermal, chemical resistance as well as dimensional stability.
Custom PET | Custom Blow Molding of Plastic Bottles.
PET containers are generally fabricated with natural crystal clear walls, but we also offer additional color and tinting options. The unique properties of PET make it an ideal material for applications requiring durability and light weight. PET plastics can be molded into simple containers or complex forms, like our popular Honey Bear Bottle.
What is a PET preform mould? - Quora
A PET preform is a test tube shaped piece of plastic that is made by a process called injection moulding, using a plastic called PET. Meanwhile a mould is a shaped hollow piece of metal, a tool, that is used to control the shape of the item being moulded.
