Hengxin PET Mould Uses 3d Computer Graphics Design

16 Oct 2017

PET is milky white or light yellow, highly crystalline polymer, the surface smooth and shiny. In a wide temperature range with excellent physical and mechanical properties, long-term use temperature up to 120 ℃, excellent electrical insulation, even at high temperature and high frequency, its electrical performance is still good.

PET Mould uses 3D computer graphics design, with a variety of domestic and foreign brands of machines, according to customer requirements, the production of a variety of blowing mold, such as: advertising bottles, shampoo, medicine bottles, soy sauce bottles, Easy to open cans, mineral water bottles, hot filling bottles, carbonated beverage bottles, liquor boxes and other molds.

Mineral water and other room temperature filling bottle blowing, PET mould is the need to cool, the temperature maintained at 50 degrees below, Coke is usually 20-30 degrees, mineral water for 10-20 degrees, and hot filling bottle blowing mold Is the need to heat around 130-145 degrees. PET plastic particles heated at different temperatures (below the melting point), the characteristics of great changes, such as higher than 150 degrees, PET particles will harden the crystal, which is the same PET bottles, mineral water bottles are not hot water, and The farmer's orchard can be heat-resistant.

The crystallization of the polymer is very incomplete, so that the polymer material of a product (of course, when the crystallinity is high), will certainly fog, turbid or opaque, in order to obtain transparent products, generally as much as possible to reduce its crystallization And the crystalline grains are as small as possible. The usual method is to control the rate of cooling, blending or addition of the resistance of the crystal and the like. Usually in the production process to control the cooling rate to adjust its transparency. PET mold opaque, and the preform is transparent, by the cooling.
