Production process and applications of recycled plastics – Injection Molding 

Injection molding is a process that uses recycled plastics, either 100% recycled material or blended with virgin resins, to produce various products—especially household items, fruit crates, and other non-food-contact goods.

The process involves injecting molten plastic into molds of various shapes as specified by product packagers or consumers. The molded products are then cooled, removed, and prepared for distribution.

Applications by industry include:

• Packaging industry: boxes, cases, lids, etc.

• Electrical and electronics: fan blades, fan bases, refrigerator trays, refrigerator bases, and basic electronic components

• Automotive industry: interior consoles, bumpers, skirts, engine covers, etc.

• Construction materials: plastic wood (wood composites)

• Household products: stationery, office and home-use items

• Toys and leisure products: LEGO blocks, water guns, etc.

Common recycled plastics used:

• High Density Polyethylene (HDPE)

• Polypropylene (PP)
