Plastic injection molding is a method of plastic products, using the pressure of the molten plastic injected into the mold of plastic products, and cooling molding to obtain the desired variety of plastic parts. Specialized machinery for injection molding injection molding machine

Plastic Injection mold

The mold is obtained after the resin material is injected into a metal mold apparatus of the products having a certain shape. Although not indicated in the drawings, in fact, in order to control the temperature of the mold, on the mold so that refrigerant (warm water or oil) through the cooling holes, such as a heater means. Melt the material has become the mainstream Road, injected into the cavity through the shunt, the gate. After cooling stage to open the top of the mold, molding machine the top of the device will be the peak of the staff, the product launch.
The resulting shape is often the final product in the installation or as a final product before use is no longer the need for other processing. Lot of detail, such as the convex portion, the ribs, threads, can be molded in the operation of the injection ...
... molding step.

Plastic Injection molding machine

Plastic Injection molding is the heat to melt the material by a high pressure enters the mold cavity, after cooled and solidified to obtain a molded article. The plastic injection molding process can be divided into the following six stages clamping, injection, packing, cooling, mold products remove.

The plastic injection molding machine has two basic components: the injection means and a mold clamping device for melting and feeding the plastic into the mold. The role of the mold clamping device in that: the mold under the live injection pressure case closed. Remove the article to the injection apparatus in the plastic injection mold prior to its melting and then control the pressure and velocity of the melt is injected into the mold. The two designs: the screw preplasticator or dual-level device, as well as reciprocating screw injection device. The screw preplasticator pre-plasticizing screw (first-class) and then melt the plastic injection material rod (second-class).

Plastic material

What are the types of plastic injection molding? Many different types of plastic, generally divided into thermoplastic and thermosetting plastics, thermoplastics after when heat softened or melted knot hard after cooling, again antipyretic still softened or melted. Is a kind of plastic, polystyrene (PS) (applied to transparent products and foam, etc.), polyvinyl chloride (PVC) (used in building pipe, etc.), polyethylene (PE) (used in day-to-day supplies more), polypropylene (PP) (applies to repeatedly force the product), acrylonitrile butadiene styrene (ABS) (uses extensively), polycarbonate (PC) (commonly known as the bullet-proof glass, widely used require high impact strength of the transparent product); poly phthalazine amine (PA) (used in self-lubricating property parts); poly of formaldehyde (POW (like PA); polytetrafluoroethylene (PTFE) ( applied the anti-corrosion products). thermoplastics with high production efficiency, good mechanical properties and dielectric properties of the advantages of lower heat resistance and stiffness, and some have reached new thermoplastic thermosetting plastic heat resistance.
