Plastic Wine Bottles Plastic Bottle House

PET bottle molding is carried out in two steps, blow molding is injection molding, then, the lower end of each PET bottle has a note material mouth, take a look at it to know. PVC is used blow molding, does not require injection, so there is no material injection port. So take a bottle up in the mouth of the injection material is PET, not the PVC. If it is mass production, then the total bottle steaming, steam at high temperatures becomes opaque PVC, PET, or transparent, sorting them both well known and easy, and steamed label tape will be after automatically unglued, light hand tear it removed. Bottle well known, only with boiling water or steam steaming, boiling water or steam through the steam into the opaque PVC, PET, or transparent, opaque voted out the characteristics of pure PET is a PET plastic bottles: ① Non-toxic, tasteless, health and safety, and can be directly used in food packaging. ② high transparency, light transmission rate of up to 90% of the packaged goods good display function. ③ high barrier and preserving flavor is good, PET for O2, CO2, water vapor permeation rate. ④ chemical stability, oil resistance fat resistance, weak acid, weak base resistance, resistance to most solvents. ⑤PET plastic bottle has excellent low temperature performance, long-term use at -30 ℃ -60 ℃.

Plastic bottle has a certain production processes and methods in production, wherein the plastic bottle processing method comprising: extrusion blow molding, injection molding, calendering, blow molding, laminating, casting, and so good in many ways. Plastic bottles are passed, blow molding, plastic is heated to melt and then pressed into a special mold and blow air pressure inside, pressure, mold plastic, form the shape of the final product, because the shape of the bottle outward pressure of time, so It emphasized that the bottle itself inwardly, the heating temperature reaches a certain level, will soften the plastic, the pressure resistance is reduced, so that the bottles will become smaller. In certain processing characteristics of the processing and production of plastic bottles, according to a grace period means processing mode for processing ,, to ensure good quality and performance of the production and processing usage. Here are the different aspects of processing characteristics in some plastic bottles: a characteristic shrinkage rate reinforced plastic shrinkage small plastic than the average pressure, which is mainly composed of chemical composition and structure of contracting shrunk. Contraction first plastic varieties of factors. Than the average epoxy phenolic, epoxy phenolic, unsaturated polyester, etc., should be large, the smallest shrinkage unsaturated polyester material. Then factors influencing shrinkage contraction of the shape and wall thickness of the plastic parts, large thick-walled, plastic and glass fiber filled contains a small volume shrinkage, volatile matter content is also very suitable for large contraction, the formation pressure, volume load contraction, heat large shrinkage colder than the lack of a large contraction of the cured release release. One of the important factors that affect the use of plastic bottles in order to prevent shrinkage and reduced shrinkage used are an important phenomenon atrophy effect in practical use. Characteristics Second, strong liquidity, and enhance the flow of plastic material is inferior to the average pressure, the liquid resin is prone to excessive accumulation and loss of glass respectively.
