Compression molding is a manufacturing process used to create solid objects from thermosetting materials, such as plastics and rubber. For example automobile rubber tires, Rubber gaskets, and gears and bearings.

The process involves heating the material until it becomes soft and pliable, then placing it between two halves of a mold and applying pressure until the material cures and takes the shape of the mold.

Examples of Compression Molding

Here are 10 main examples of products and materials that can be produced through compression molding:

1. Bakelite Handles

The bakelite handle is the best example of compression molding. Bakelite is a thermosetting plastic that is often compression molded to create handles for cookware and tools due to its heat resistance and durability.

2. Brake Pads

Brake pads for automobiles are commonly made using compression molding with materials like friction compounds and resins.

3. Electrical Insulators

Compression molding is used to produce electrical insulators made from materials like melamine or glass-reinforced epoxy.

4. Rubber Seals

Sealing components, such as O-rings and gaskets, are manufactured through compression molding using various rubber compounds.

5. Fiber-Reinforced Composites

Composite materials like fiberglass or carbon fiber composites can be compression molded to create strong and lightweight parts for aerospace and automotive applications.

6. Toilet Seats

Plastic or thermoset toilet seats are often produced through compression molding for their durability and ease of cleaning.

7. Melamine Tableware

Plates, bowls, and other melamine-based tableware items are commonly manufactured using compression molding due to their heat resistance and durability.

8. Urethane Bushings

Suspension and automotive bushings are made through compression molding using polyurethane materials for their durability and vibration-damping properties.

9. Rubber Tires

The tread patterns on rubber tires are created through compression molding to ensure good traction and wear resistance.

10. Phenolic Resin Components

Various parts, such as electrical connectors and circuit boards, can be made using compression molding with phenolic resin materials for their electrical insulating properties.

These examples demonstrate the versatility of compression molding across different industries and materials for creating a wide range of products.
