Compression & Hot-Press Molding

Large-format, thick-section and composite-reinforced parts — compression molding with a 500T four-column hydraulic hot press.

Process Overview

Compression Molding — When a Part Is Too Large for Injection

Compression molding applies heat and pressure to a pre-placed charge of material in an open mold, forcing it to fill complex cavities in one controlled stroke.

Large-Format & Thick-Section Capability

Our 500T four-column hydraulic hot press handles large-format and thick-walled parts that exceed the limits of conventional injection molding — ideal for CF-PEEK composite laminates, plates and structural profiles.

  • 500T four-column hydraulic hot press
  • Large-format and thick-section parts beyond injection limits
  • Excellent for CF-PEEK composite and laminate molding
  • High dimensional and density consistency
Why Compression Molding

Key Advantages

How compression molding delivers for demanding applications.

Large Format

Parts and plates beyond the platen limits of injection molding.

Thick Wall

Thick cross-sections molded consistently without sink or voids.

Composite-Ready

Ideal for CF-PEEK and fiber-reinforced laminate molding.

Consistency

High dimensional and density repeatability part to part.

Applications

Typical Compression-Molded Parts

Where compression molding is the right choice.

Large PEEK sealing components

Large Sealing Components
