Pet cosmetics packaging production of cosmetics packaging production the brief analysis of embryo transfer program

PET( Polyester) Beverages cosmetics packaging production development in China is only more than a decade, and hot filling beverage PET cosmetics packaging production in China's history is shorter, only for six years, but the development momentum of the more than most other packaging container. As is known to all, tea drink, fruit juice beverages is the key point of the development of the beverage, most of which container are choose PET hot filling cosmetics packaging production, and the proportion is rising trend. PET beverage general production of cosmetics packaging production process is: injection into cosmetics packaging production are cosmetics packaging production embryos after a heated vertical stretching a transverse stretching a cosmetics packaging production molding. If the final shape in the process of production using mechanical cold stereotypes, PET son cosmetics packaging production in use once temperature reach PET glass transition temperature ( 78℃) , its molecular chain can relax, cosmetics packaging production zi chan serious shrinkage, so this kind of cosmetics packaging production child filling is only suitable for cold drinks. The hot filling cosmetics packaging production in the process of stretching to finalize the design process, always at a higher temperature ( About 140 ℃) , PET molecular chain was high temperature to finalize the design in flabby condition, eventually produce a lot of cosmetics packaging production, dense knot, knot degree can reach 30% ~ 45%, the production of cosmetics packaging zi chan had high heat resistance, and become the hot filling cosmetics packaging production of practical significance. Initially, consumers just focus on the quality of the drinks, beverage and now also gradually begin to pay close attention to the outer packing. PET cosmetics packaging production depends on the quality of the supplied cosmetics packaging production quality of embryo, embryo cosmetics packaging production injection molding was divided into two kinds, one kind is long gate, the other is a short gate. Domestic cosmetics packaging production embryo manufacturers choose short gate cosmetics packaging production of embryo is more, and choose a long gate more abroad. Long gate of cosmetics packaging production due to cut off the gate at the bottom of the embryo, the tension in the process of cosmetics packaging production were distributed evenly, so out of cosmetics packaging production quality will be better, also can cut off part of the recycling, it helps to save raw material costs, in today's increasingly scarce oil resources, domestic manufacturers would prefer Yu Changjiao cosmetics packaging production of embryos. Embryo in the process of production of cosmetics packaging production quality control depends on the cosmetics packaging production embryos in the process of conveying the degree of control to avoid scratches. Now most of the domestic manufacturers of cosmetics packaging production of embryo transfer using belt conveyor, this is a more ancient way of conveying process. This transport shortcomings are as follows: cosmetics packaging production out of the embryo in the injection molding machine, temperature 45 ℃ - 55℃。 Directly into belt can cause bumps between embryo cosmetics packaging production. & U % N * | 'd8 ^ and cosmetics packaging production embryo chaotic pile up on the belt, cosmetics packaging production embryo is not very uniform cooling. + k, n4 ? 。 N4 interchange q cosmetics packaging production embryo out of the plastic injection machine, there may be a single cavity injection into the embryos have quality problem, stacked together which is difficult to judge with chaotic cavity of cosmetics packaging production problems. Injection molding in the injection molding cosmetics packaging production embryo when a cavity may form a cavity, so chaotic is arranged, if still according to the injection molding cavity number to count, the count will be inaccurate. - Q# d# T# A- V !

Cosmetics packaging production embryo is out by manipulator, not directly, avoid scratches. Because the position of each cosmetics packaging production embryos have serial number, when occurrence problem of injection molding machine injection embryos, can accurately find out the problems which cavity. 2, through the clamp plate chain of cosmetics packaging production of embryo, embryo neck to transport cosmetics packaging production in the cosmetics packaging production embryo orderly transportation in a certain order.
