Compression molding uses heat and pressure to shape rubber into the desired shape. A heated mold tool and the clamping pressure of a press are used to form the rubber. Before cooling and extraction of the final portion, the rubber undergoes chemical changes known as the curing or vulcanization process.
Compression molding has the benefits of a less complicated procedure, entails cheaper tooling expenses, ideal for making huge products and parts with a lot of thickness. It’s a terrific option for multi-color molding and inserts molding and for short production runs, it is cost-effective.
Injection molding and compression molding are comparable procedures that both employ heat and pressure. Injection molding, on the other hand, uses a screw and a hooper to transport the material, whereas compression molding does not.
Molding is the process of pushing a block of rubber into a metal chamber to create rubber pieces. The rubber inside the cavity is then heated, causing a chemical reaction to occur. Rubber injection molding, compression molding, and transfer molding are the 3 most popular techniques.
The global rubber consumption is expected to expand at a CAGR of 4.8 percent from 2019 to 2023, with production reaching 17MMT (million metric tons) by 2022, up from the present level of 12.43 MMT.
The global industrial rubber market size was valued at $29.8 billion in 2018 and is predicted to reach $44.6 billion by 2026, rising at a CAGR of 5.2% from 2019 to 2026.
Rubber is one of the most significant polymers for human society. Natural rubber is an essential raw material utilized in the manufacturing of more than 40,000 goods. It is utilized in medical gadgets, surgical gloves, aero-plane and automotive tires, pacifiers, garments, toys, etc.
