Compression Molding

Compression molding is the most fundamental method for molding rubber. It is implemented by placing a cut-to-weight quantity of uncured rubber into the cavities of an open mold. The mold is then closed, as far as possible, and placed into a hydraulic press. Pressure from the press causes the uncured rubber to form into the shape of each cavity, as heat from the hydraulic press vulcanizes the product.

Advantages of Compression Molding:

• Inexpensive tooling
 -Molds are generally simple.
• Less compound waste
 -Unlike transfer molding, there is no pot-rind.
• Excellent choice for bulky and high durometer parts
 -To avoid flow problems.
• Good for low production runs.

Disadvantages of Compression Molding:

• Longer compound preparation time
 -A compound segment must be prepared for each cavity.
• Labor-intensive finishing
 -The product flash is generally thick.
