Health care Health Products HDPE Plastic Bottle molding methods which?

HDPE plastic bottle molding choice depends mainly on the health care Health Products HDPE Plastic Bottle type (thermoplastic or thermosetting), the initial form and the shape and size of the product. Processing of thermoplastic health care Health Products HDPE Plastic Bottles commonly used methods are extrusion, injection molding, rolling, blow molding and thermoforming, processing thermosetting health care Health Products HDPE Plastic Bottles are generally molded, transfer molding, but also with injection molding. Health care Health Products HDPE Plastic Bottle molding is a variety of forms (powder, pellets, solutions and dispersions) health Health Products HDPE Plastic Bottles made of the desired shape of the product or blank process. Forming up to thirty kinds of methods. Laminated, molded and thermoformed is made in the form of a health care product HDPE plastic bottle on a flat surface. The above-mentioned health care Health Products HDPE Plastic Bottle processing methods, can be used for rubber processing. In addition, there are liquid monomer or polymer as raw materials such as casting. In these methods, the use of extrusion and injection molding is much more, but also the basic molding method. Health Health Products HDPE Plastic Bottles are synthetic resin and a variety of additives as raw materials, injection, extrusion, pressing, casting and other methods made of. Health Health Products HDPE Plastic Bottle products in the molding at the same time, also obtained the performance, so health care Health Products HDPE Plastic Bottle molding is the production of key processes.

01

injection

Injection molding, also known as injection molding, is the use of injection machine will melt the health care Health Products HDPE Plastic Bottles into the mold quickly, and curing a variety of health care Health Products HDPE Plastic Bottle method. Almost all of the thermoplastic health care Health Products HDPE Plastic Bottles (except fluoride health Health Products HDPE Plastic Bottles) can be used this method can also be used for some thermosetting health care Health Products HDPE Plastic Bottle forming. Injection molding accounted for health care Health Products HDPE Plastic Bottle production of about 30%, it has a shape of a complex shape, size, accuracy, high productivity; but the equipment and mold costs higher, mainly for high-volume health care Health Products HDPE Plastic Bottles The production.

Injection molding machine commonly used are plunger and screw type two, injection molding principle: the powdery granular material from the hopper into the barrel, the plunger to promote, the raw material was pushed into the heating zone, and then through the shuttle shuttle, through the nozzle will melt Health care Health Products HDPE Plastic Bottles into the mold cavity, after cooling open health products that HDPE plastic bottles. Note HDPE plastic bottle parts removed from the mold cavity after the need for proper post-processing to eliminate health care Health Products HDPE Plastic Bottle parts in the formation of the stress, stability, size and performance. In addition, there are cut burrs and gates, polished, surface finish and so on.

02

Extrusion

Extrusion is the use of screw rotation and compression methods, continuous plasticized health care Health Products HDPE Plastic Bottles squeezed into the mold, through a certain shape of the die, get the shape with the mold to adapt to the health care Health Products HDPE Plastic Bottle profiles Process method. Extrusion of plastic products accounted for about 30% of HDPE plastic bottles, mainly for a certain cross-section, the length of a variety of health Health Products HDPE Plastic Bottle profiles, such as health Health Products HDPE Plastic Bottles, plates, rods, Cross section of the complex shaped material. It is characterized by continuous forming, high productivity, simple mold structure, low cost, close organization and so on. Fluoride plastic health Health Products HDPE Plastic Bottles, almost all of the thermoplastic health care Health Products HDPE Plastic Bottles can be extruded, part of the thermosetting health care Health Products HDPE Plastic Bottles can also be extruded forming. The right picture shows the spiral extrusion plan, the granular health care product HDPE plastic bottle from the hopper into the spiral propulsion room, and then by the rotating screw to the heating zone melting, and by compression; in the role of the screw force, forced by a certain The shape of the extrusion die, get the shape of the cross-section with the profile of the profile; fall into the conveyor belt after the jet air or water to cool it hardened to get cured health care Health Products HDPE Plastic Bottle parts.
