How To Making Plastic Bottle

Plastic bottle processing is defined by the synthetic resin manufacturing plant polymers made the final plastic products process. The processing method includes plastic pressure, extrusion moling, injection molding, blow molding, calendaring molding and other.

1 .plastic pressure

Plastic pressure mainly for phenolic resin, urea-formaldehyde resin, unsaturated polyester resin and thermosetting plastic injection molding.

2 .extrusion molding

Extrusion molding is the use of extrusion die heating continuous resin through the mold, extrusion of the desired shape of the products method. Extrusion and sometimes in the thermosetting plastic injection molding, and can be used for foam molding. Extrusion can extrude a variety of shapes of products, high production efficiency, and can be automated, continuous production; drawback is not widely adopted the method of thermosetting plastic products processing, easy size deviation.

3. injection molding

Injection molding is the use of injection molding machine thermoplastics melt under high pressure is injected into the mould after cooling, solidification process for obtaining a product. The injection can also be used for thermosetting plastic and foam molding. Injection molding has the advantages of fast speed, high production efficiency, operation can be automated, forming the shape of complex parts, particularly suitable for mass production. Disadvantage is high cost of equipment and tooling, plastic injection molding cleaning is difficult.

4. blow molding

Blow molding is the use of blowing mold with the aid of the pressure of the compressed air so that the closure in the mold of hot resin parison is a method of hollow products, blow molding including blown film and hollow blow molding products of two kinds of methods. By a blow moulding method can produce film products, all kinds of bottles, cans, pots containers and toys for children.

5 .calender molding

Rolling is the resin and various additives by expected after treatment through rolling machine two or more steering opposite calendering roll gap is processed into a film or sheet, then from the rolling mill roller and stripped down, after cooling and shaping a molding method. Calendering is mainly used in PVC resin molding method, can make the film, sheet, plate, artificial leather, floor tiles and other products.

6. calendering

Foamed material adding foaming agent, the plastic to produce a microporous structure process. Almost all of the thermosetting and thermoplastic plastics can be made of foam. According to the pore structure is divided into open pore foam and closed-cell foam, which is mainly composed of manufacturing method of decision.

Plastic bottle processing in the first is bottle design. Plastic bottle manufacturing is completed using a filling machine, inject the liquid inside, then you can get the finished product packaging.
