Guangzhou plastic bottle manufacturer for you decrypt plastic production and processing methods
Plastic bottles is part of the rubber and plastic industry, no matter what plastic bottles, after forming.
Plastic forming process is phenolic resin, urea formaldehyde resin, unsaturated polyester resin process of plastic products such as polymers.
Its processing method including molding, extrusion, injection molding, blow molding, calendering, etc.
Next, the constant win packaging will give the broad masses of netizens share some information about guangzhou plastic bottle manufacturer, the hope can help Internet users in need!
Guangzhou guangzhou plastic bottles manufacturers producing method of plastic, introduce to you is as follows: 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.
A high temperature, preheat the bottle embryo by lamp irradiation, 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 operation.
Second, bottle blowing molding this phase is to place already preheated bottle embryo is ready to die, 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 two operations together to complete, from the middle of artificial will be preheated bottle embryo in mold process.
Greatly speed up the production rate, and of course the price also is higher than semi-automatic.
Guangzhou guangzhou plastic bottles manufacturers to introduce you to the plastic processing method, as shown in the following: 1, injection molding is also called injection molding.
Injection molding is the use of injection molding machine,
Or the injection machine)
Will thermoplastics melt under high pressure into a 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 equipment and mould cost is high, the injection molding machine cleaning is difficult, etc.
2, rolling 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.
Above is to win constant to the broad masses of netizens packaging manufacturers to share information about guangzhou plastic, hope to be able to help better understand netizens plastic bottle production method and processing method.
