3 Types of Compression Molding and How They Work

compression molding

Did you know that carbon fiber molding plays a crucial role in the medical industry? Carbon fiber composites have changed how modern prosthetic devices are made in the medical field. Using carbon fiber has allowed for the production of prosthetics that are stronger, lighter, and more comfortable for patients to wear.

Compression molding is a popular manufacturing technique in the composite industry, particularly for carbon fiber products. It is a process of molding composite materials into a specific shape by applying heat and pressure. Below, we will discuss three types of compression molding and how they work.

1. Compression Molding: Cast Molding

Cast molding is a cost-effective and efficient way to produce large quantities of carbon fiber products. It is commonly used in the automotive and sports industries for creating high-performance parts such as the following:

  • Car body panels
  • Sports helmets
  • Tennis rackets

Cast molding is a compression molding technique. They pour the composite material into a mold and then compress it using a hydraulic press. The mold is made of two parts:

  • The cavity
  • The core

They pour the composite material into the cavity and place the core on top. The hydraulic press then compresses the mold. This pressure then forces the composite material to fill the cavity and take the shape of the mold.

2. Compression Molding: Bladder Molding

Bladder molding is commonly used in the aerospace industry to produce parts such as wing skins and fuselage panels. It is also used in the manufacturing of medical equipment such as prosthetics and braces.

Bladder molding is a technique that uses an inflatable bladder to apply pressure to the composite material. The bladder consists of a flexible material such as silicone or rubber.

They insert the bladder into the mold before the composite material. The mold is then heated, and the bladder is inflated, which presses the composite material against the mold.

3. Compression Molding: Transfer Molding

Transfer molding is a technique that uses a plunger to transfer the composite material from a pot into a heated mold. The plunger compresses the composite material and forces it into the mold cavity. The mold is then heated to cure the composite material and give it its final shape.

Transfer molding is commonly used in the electrical and electronic industries for producing parts such as circuit boards and electrical connectors.
