Introduction

A vacuum type block molding machine is an essential piece of equipment in the manufacturing process of expanded polystyrene (EPS) blocks. This machine utilizes vacuum technology to mold EPS beads into blocks with precise dimensions and consistent quality. The integration of vacuum ensures that the blocks are void-free and possess enhanced mechanical properties.

Operation of a Vacuum Type Block Molding Machine

The operation of a vacuum type block molding machine involves several critical steps:

  1. Pre-expansion of the EPS beads to achieve the desired density.
  2. Filling the block mold with the pre-expanded beads using a pneumatic or mechanical filling system.
  3. Application of steam to soften the beads and weld them together.
  4. Introduction of vacuum to extract air and ensure tight packing of the beads.
  5. Cooling and demolding of the solidified block.

The entire cycle time ranges between 4 to 7 minutes depending on the size and density of the block.

Key Features

  • Capacity: Produces blocks with dimensions ranging from 500x500x3000 mm to 1200x1200x6000 mm.
  • Density Range: Supports densities from 8 kg/m³ to 35 kg/m³.
  • Steam Pressure: Operates with a steam pressure of 0.8 to 1.0 MPa.
  • Vacuum Level: Achieves vacuum levels of up to -0.06 MPa.
  • Cycle Time: Typical cycle time is between 4 and 7 minutes.
