'Cosmetic' manufacturer decryption plastic production and processing method for you!
plastic forming process is phenolic resin, urea formaldehyde resin, unsaturated polyester resin process of plastic products such as polymers. Recently often have friends boasts about plastic processing method, in fact, as a result of current cosmetics bottle is PETG materials, production enterprises and plastic bottles the same. Small make up today said, its processing method including molding, extrusion, injection molding, blow molding, calendering, etc. Next, suye will give the broad masses of netizens share the related information of taizhou plastic bottle manufacturer, the hope can help Internet users in need!
cosmetics bottle manufacturer of cosmetics bottles manufacturer to introduce to you the plastic bottle producing method, as shown in the following:
there are a number of ways for manufacturing polyethylene, one of the most common, is high temperature at 200 ~ 300 ℃ and 1000 ~ 2000 atmosphere pressure, will be made from ethylene polymerization. In polyethylene, not mixed with other substances. That of low density polyethylene, texture soft, for sunshine, air, water and chemical reagents, have higher stability, so no additional stabilizer, plasticizer, stabilizer and plasticizer is mostly toxic or to be toxic.
will be a bottle embryo through high temperature and light cosmetics packaging tube light, heating softening of the body of bottle embryo part, in order to keep the bottle shape, bottle embryo is don't need to be heated, so you need a cooling device for cooling operations.
2, bottle blowing molding
this phase is to place already preheated bottle embryo to already made cosmetics cosmetics packaging hose production mold, for its high pressure gas, blow the bottle embryo to form the bottle.
on the market generally divided into fully automatic and semi-automatic bottle blowing machine. Automatic bottle blowing machine through the operation of the manipulator will bottle blowing the two together to complete the operation, from among the artificial put preheated bottle embryo in cosmetics cosmetics packaging hose production mold process. Greatly speed up the production rate, and of course the price also is higher than semi-automatic.
cosmetics bottle manufacturer of cosmetics bottles manufacturer to introduce to you the plastic processing method, as shown in the following: 1, injection
injection and injection molding. Injection molding is the use of injection molding machine, Or the injection machine) Thermoplastics melt under high pressure injection to cosmetics cosmetics packaging hose production mold Canon of cooling and solidification get products. Injection molding can also be used for thermosetting plastic and foam plastic forming. Injection molding is the advantage of production speed, high efficiency, operation can be automated, to forming of complex shape parts, especially suitable for mass production. Defect is soft hose cosmetics packaging equipment and cosmetics production mould cost is high, the injection molding machine clean up more difficult, and so on.
2, press the
rolling is to pass through the expected processing (resin and all kinds of additives Kneading, filter, etc. ) By calender after two or more steering instead of rolling roller clearance processed into thin film or sheet, then falls off from the calender roller, then through cooling finalize the design of a forming method. Calender is mainly used in PVC resin molding method, can make film, sheet, plate, artificial leather, floor tile and other products.
to summarize: the above is suye summary for friends, about the decryption plastic production and processing method. 'All of the content, I hope to inspire you. Also want to know more information about plastic bottles please collect on this site. 【 。 】
