Top-pressing hydraulic machines.
Bottom-pressing hydraulic machines.

Common mold types include:

Overflow molds
Non-overflow molds
Semi-overflow molds

The Process Flow of Compression Molding

The typical process includes the following steps:

Measuring: Accurate measurement is critical, using weight, volume, or counting methods.
Pre-pressing: Reduces compression ratios and improves thermal transfer.
Preheating: Increases curing speed and improves material flow.
Insert Placement: Ensures correct positioning for components like conductive parts.
Feeding: Accurate feeding is crucial for achieving desired product specifications.
Closing Molds: Rapid initial closing followed by a slower approach to prevent damage.
Ventilation: Essential for expelling gases and moisture during the process.
Curing: Achieved through controlled pressure and temperature.
Demolding: Typically occurs while the material is still warm, utilizing ejector rods.
Post-processing: Involves additional treatments to ensure product quality.
