Plastic injection molding is the method when under high -pressure, the injection of melted plastics or resins is made into custom-designed molds to produce plastic items which can be used by various industries like automobiles, white goods, air conditioning etc. By custom designing molds, various shapes and sizes of the plastic products can be produced

A very high efficiency is achieved in this plastic injection molding process, enabling delivery of parts whose precision is very high and at the same time giving the manufacturer the benefit of high-volume production which leads to very high-cost effectiveness.

The step-by-step process to deliver a plastic part using the molding process is detailed below:

• First, the correct raw material is chosen – this is done based on the characteristics of the finished part.
• The molding operator feeds the selected compound(s) into a barrel heater that contains a reciprocating screw and heated runners to melt and direct the material.
• The reciprocating screw and/or runners heat the plastic(s) or resin into a molten liquid state, and the screw pushes the melted material down the barrel toward the injector nozzle.
• The nozzle injects the material at high speeds into a mold in the shape of the desired part or component. The mold is made out of steel or aluminium. The injector pressure and timing ensure that all sections of the mold are filled.
• The injected material cools into the shape of the mold and then ejects the solid part from the mold manually or through the use of ejector pins.
• Finally, if there are any pieces that need to be stripped off/cut, then this is done and the final part is delivered. The delivered part is very accurate in terms of its precision and its weight.

All of the parameters of the injection molding process-including the cycle and injection timing, injection pressure, and cooling time-are determined based on the material and product design.

1. Polyoxymethylene or Acetal – Acetal-also known as polyoxymethylene (POM)-is a durable and dimensionally stable thermoplastic with excellent chemical, creep, and wear resistance. It is often used for the manufacture of contacting parts such as belt buckles and engineering components such as bearings and bushes.
2. Poly(methyl methacrylate) or Acrylic Glass – Acrylic Glass also referred to as polymethyl methacrylate (PMMA)-is a transparent and rigid plastic valued for its light transmission and weathering properties. Typical applications include use as a more durable alternative to glass in pictures frames, car windows, and eyeglasses.
3. Acrylonitrile butadiene styrene (ABS) – ABS is a strong and rigid thermoplastic that offers excellent moldability and glossy, colour-fast surface finishes. It is suitable for the manufacture of a wide range of products that do not require high chemical, electrical, or UV resistance, such as indoor appliances, toys, and luggage.
4. High-impact polystyrene (HIPS) – Polystyrene is a low-cost plastic that is highly machinable and customizable and demonstrates good impact resistance and dimensional stability. As it readily accommodates printing, gluing, bonding, and decorating, it is often used in printing and other graphical arts applications, such as posters, signs, and displays.
5. Low-density and high-density polyethylene (LDPE/HDPE) – LDPE and HDPE are polyethylene variations. LDPE offers greater flexibility and a lower melting point, while HDPE provides greater rigidity and a higher melting point. Both materials are used for the manufacture of a variety of products, ranging from packaging to toys.
6. Nylon – Nylon-also is known as polyamide-is a highly durable plastic material with excellent chemical, temperature, and abrasion resistance. It is easily combined with other chemicals to enhance certain features for use in a wide range of industrial and consumer products.
7. Polypropylene (PP) – PP is a widely used thermoplastic valued for its durability, elasticity, transmissivity, and insulating properties. It is often used in automotive, household, and medical components.
8. Thermoplastic polyurethane (TPU) – TPU is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
9. Hytrel® thermoplastic polyester elastomer – TPE include mechanical and physical properties such as exceptional toughness and resilience, high resistance to creep, impact and flex fatigue, flexibility at low temperatures, and good retention of properties at elevated temperatures. thermoplastic polyester elastomer typically is used in demanding applications in the automotive, fluid power, electrical/electronic, consumer goods, appliance and power tool, sporting goods, furniture, industrial and off-road transportation/equipment industry.
10.  Santoprene® Thermoplastic Vulcanizate (TPV) – TPV material combines good physical properties and chemical resistance for use in a wide range of applications. This grade of Santoprene TPV is shear-dependent and can be processed on conventional thermoplastics equipment for injection molding, extrusion, or blow molding. It is polyolefin-based and completely recyclable.
11.  Polyvinyl Chloride (PVC) – Polyvinyl chloride is a thermoplastics material that consists of PVC resin compounded with varying proportions of stabilizers, lubricants, fillers, pigments, plasticizers, and processing aids. Different compounds of these ingredients have been developed to obtain specific groups of properties for different applications. However, a major part of each compound is PVC resin.
12. Polycarbonate (PC) – Polycarbonate is a high-performance tough, amorphous, and transparent thermoplastic polymer with organic functional groups linked together by carbonate groups and offers a unique combination of properties. Some of the common applications are compact disc, safety helmets, bullet-proof glass, car headlamp lenses, roofing, and glazing, etc.
13. Polybutylene Terephthalate (PBT) – PBT is high-performance engineering plastic that combine high strength and rigidity with excellent processing characteristics. PBT is well suited for a broad range of automotive, electrical & electronic, and consumer goods applications.
