What Is Injection Molding Used for?Injection molding is used for

manufacturing plastic, rubber and metal. Materials are fed through a heated barrel in the machine and forced into a mold where it will cool and take its shape. An injection molding machine can stamp out metal car shell parts, rubber valve steam seals, and even plastic toys for kids.

Injection Molding in RubberInjection molds make many rubber automobile parts. It makes valve steam seals and oil seals for the engine. It also makes earplugs, rubber hoses and telecommunications items.

Processes included:-Sand BlastingShot BlastingMachiningPhosphating

Sand Blasting:-Sandblasting is a process that is used for stripping away old paint and rust.In this compressed air having abrasive particles is stricked to material.

Shot Blasting:-Shotblasting is a method used to clean, strengthen (peen) or polish metal. Shot blasting is used in almost every industry that uses metal, including aerospace, automotive, construction, foundry, shipbuilding, rail, and many others.

Machining:-CuttingWeldingShaping

Phosphating:-Phosphating is a chemical process for

treating the surface of steel whereby metal-phosphate layers that are hardly soluble are formed on the base material. The layers created are porous, absorbent and are suitable without further treatment as a conversion layer for subsequent powder coating. It is done in 11 tanks.

Phosphating tanks:-Tank 1-3

Tank 4-6

Tank 7-9

Tank 10-11

Die Manufacturing Section:-A die is a specialized tool used in manufacturing

industries to cut or shape material mostly using a press. It is made by CNC machine.

Rubber Compounding Section:-Processes includes:-CurativesAnti-oxidantPigmentsReinforced fillersPlasticizers

Injection Moulding Process:-Material granules are melted down and injected into the mold.

The mold is held under pressure until the material cools and hardens.

Once the material hardens, the mold is opened and the part is removed.

And the process can be repeated.

Paint Section:-To protect material from corrosion

Done by spray or hand brush
