Learn about rubber compression molding, its process, advantages, types of rubber used, and its applications in industries.
Rubber compression molding is a process that is used to make custom rubber parts. This process involves putting a rubber material into a mold and heating and pressing it to make it take the shape of the mold. This method is used in many industries, including the automotive, aerospace, medical devices, and consumer goods industries.This guide will talk about how rubber compression molding works, its advantages, the materials it uses, and how it is used.
What is Rubber Compression Molding?
Rubber compression molding is a process where rubber is placed into an open mold that has been heated. The mold is closed, and the rubber is subjected to both pressure and heat. This causes the rubber to cure and take the shape of the mold.Compression molding is particularly well-suited for producing rubber components that require high precision, durability, and strength.
How Does Rubber Compression Molding Work?
The process of rubber compression molding involves several key steps:
Material Preparation: Rubber, often in the form of a pre-measured amount of raw material such as rubber compounds, is prepared for the molding process. The rubber can be in solid form, granules, or preformed into a slug.
Loading the Mold: The rubber material is placed in the open cavity of the mold. This is typically done manually or automatically depending on the manufacturing setup.
Closing the Mold: The mold is closed, and heat is applied. The rubber material begins to flow and spread to fill the mold cavity completely.
Curing: The heat causes the rubber to harden, transforming it from a soft, malleable material into a solid part. The curing time depends on the type of rubber and the mold temperature.
Opening the Mold: Once the curing time is complete, the mold is opened, and the finished part is removed. In some cases, extra material (flash) may be trimmed off to give the part a clean finish.
