Little knowledge about PET bottle embryos!

PET bottle preform is a typical injection molding product, which is easy to transport. Most of it is made of plastic material, with uniform texture and good insulation. It is an intermediate product of plastic bottles and oil drums. Under a certain temperature and pressure, the mold is filled with raw materials, and under the processing of the injection molding machine, it is processed into a preform with a certain thickness and height corresponding to the mold.

Polyethylene terephthalate is the most important variety of thermoplastic polyesters. The English name is Polythylene terephthalate, abbreviated as PET or PETP (hereinafter referred to as PET), commonly known as polyester resin. It is a polycondensate of terephthalic acid and ethylene glycol, and together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester. PET is a milky white or pre-yellow highly crystalline polymer with a smooth and glossy surface. It has good creep resistance, fatigue resistance, friction resistance and dimensional stability, low wear and high hardness, and has the largest toughness among thermoplastics; good electrical insulation performance, small temperature influence, but poor corona resistance. Non-toxic, weather resistant, good chemical stability, low water absorption, weak acid and organic solvent resistance.

PET bottles are often used for packaging, and the packaging is often stacked in layers during transportation or inventory. At this time, we will take into account the pressure tolerance of the bottom layer of Z. During the PET bottle compression test, place the PET bottle in the two horizontal pressure plates of the machine, and start the PET bottle compression machine of Suzhou Ouyi, and the two pressure plates will pressurize at a certain test speed. The instrument stops automatically when it crashes and saves the data automatically. The routine inspection of PET bottles includes bottle wall thickness inspection, compression resistance inspection, and bottle cap opening fatigue inspection.

PET bottles have strong applicability and are widely used in daily necessities, daily chemical packaging and other fields. From mold processing to machinery and equipment, they are extremely picky, easy to get started, and difficult to do. PET preforms are reprocessed by blow molding to form plastic bottles, including bottles used for packaging of cosmetics, medicine, health care, beverages, mineral water, reagents, etc. A method of forming a PET plastic bottle through blow molding.

4 Cavity Bottle Mould
