plastic injection

Plastic injection is one of the most widely used and easiest methods used to form polymers. It is generally considered a type of casting in which molten materials such as metals and glass, which are usually plastic, are injected into the mold under pressure.

For this, we need a plastic injection machine. After the production of plastic, the plastic injection machine came to the market so that we can easily make the plastic raw materials into the shape we like. Plastic injection is the best way to create plastic products. Plastic injection is used in the manufacture of many objects such as packaging industries, electrical and telephone wiring methods, liquid battery lids, parts and vehicles, toys, tables and chairs, boxes, etc.

 

The most important plastic raw materials include the following materials:
• PE
• Polypropylene
• Polystyrene

ABS plastic injection:

ABS plastic injection is a great choice for molding because it is relatively inexpensive and also has a high resistance to breakage. The question that arises is why ABS plastic injection is used. There are many reasons because one of the materials used in this model is acrylonitrile styrene butadiene, which is a material known for its high strength and impact and is resistant to scratches. be ABS has a low melting point and is a cheap material.

Advantages of using ABS plastic injection mold:

• Cost (it was mentioned in the previous explanation that this model is cheap)
• Paintable
• It has great strength to weight ratio
• The final product has more strength and rigidity

ABS molding parts are used in a wide range of industries such as manufacturing, medicine, automotive and marine. ABS is not recommended at all for food applications.

HIPS plastic injection:

HIPS plastic injection with high effect of polystyrene. It is versatile, economical and resistant to all kinds of plastic impacts. The properties of using HIPS plastic injection, impact and maintaining high strength in applications, can be recycled, can be painted, glue and fast assembly, easily used in all kinds of geometry models. The main and important application of HIPS plastic injection is in the storage of containers and sheets.

Polypropylene (PP) plastic injection:

Polypropylene plastic injection, which is called pp. It is widely used in product design and is used in production and packaging. Polypropylenes are from the thermoplastic family, which means they become softer when heated.

Polypropylene (PP) injection properties:

1- The low prices 2- The feature of combining metals such as metal cores and metal bushings during injection 3- The possibility of making composites with the feature of combining materials such as sawdust 4- Production of toys and entertainment devices for children because these materials are not at all They are not poisonous and are not dangerous.

 

Polystyrene plastic injection:

Polystyrene plastic is hard and relatively cheap, and due to its special features and the low cost of production, it has many uses today, for example, disposable food containers, disposable cups are made of polystyrene, and its characteristics are excellent color, hardness, It is transparency. The special application of polystyrene is usually extruded and injection molded items. Polystyrene is used in block and sheet form in electrochemical applications and lenses.

 

Advantages of polystyrene:

The insulation is good, it has excellent resistance to liquids and water.

 

Disadvantages of polystyrene:

The weakness of polystyrene is its breakage, low stability against UV light, it is flammable (which improves its flammability with the addition of halogen).

PVC extrusion:

PVC extrusion is a widely used method for forming profiles from plastic materials. Extrudes are divided into two types, single spiral and double spiral. The single-screw extruder has good and high flexibility, and its internal analysis is easier. According to the direction of rotation and the position of the two spirals, the twin-screw extruder can recognize various types of spirals, such as spirals with parallel and reverse movement, comb, non-comb and comb type spirals.
