In the pulp molding industry, the hot press forming machine heats the press plates to a set temperature while the hydraulic system applies strong pressure, shaping pulp molded products and giving them a smoother, more attractive appearance.

Paper trays shaped by the hot press forming machine have a smooth, dense surface, are less likely to deform, and improve the product’s quality.

This machine usesPLCcontrol, applies15 tons of pressure with high-temperature forming, and completes each cycle in just 6–10 seconds, quickly shaping various paper trays.

Hot Press Forming Machine के कार्य

The hot press forming machine is the core equipment in high-quality egg tray and paper tray production lines. Its forming effect directly affects the product’s structural stability and surface smoothness.

  • High-Temperature Heating:Heats the mold and material so that pulp or fibers soften fully, improving forming quality.
  • High-Pressure Forming: Uses hydraulic or mechanical pressure to compress the material, ensuring uniform density, strong structure, and stable dimensions.
  • Fast Cycle:Sets forming time to complete pressing, cooling, and demolding in a continuous operation, increasing production efficiency.
  • Automatic Control: PLC or touchscreen control allows precise adjustment of temperature, pressure, and time, with built-in safety features.
  • Multi-Material Compatibility: Can handle pulp, wood chips, fiberboard, plastic sheets, and other materials, flexibly meeting different product needs.

Working Principle of the Hot Press Forming Machine

The hot press forming machine quickly shapes and dehydrates semi-wet pulp products using high temperature and hydraulic pressure. Heat evaporates moisture in the pulp, while pressure flattens the surface, ensures even thickness, and strengthens the product with stable dimensions. The entire process is managed by a PLC intelligent control system, making operation simple, efficient, and stable. It is a key machine in producing paper trays, egg trays, pulp lunch boxes, and other pulp molded products.

Structure of the Hot Press Machine

The hot press machine consists of cylinders, guide rods, frame, adjustment plate, upper mold, lower mold, pressure regulating valve, and a hydraulic manifold (three-in-one unit).

  • Adjustment Plate:Adjusts mold distance or pressure height to fit different pulp thicknesses.
  • Upper Mold:Shapes the top surface of the product and applies pressure for hot pressing.
  • Lower Mold:Supports the bottom of the product and works with the upper mold to complete forming.
  • Hydraulic Manifold (Three-in-One Unit):तेल प्रवाह को नियंत्रित करता है, भेजना-छोड़ना, और हाइड्रोलिक दबाव का नियंत्रण।
  • Pressure Regulating Valve:Adjusts hydraulic pressure to ensure stable and safe forming.
  • Guide Rods:Keep upper and lower molds moving parallel during pressing, improving forming accuracy.

Position in the Workflow

Typicalegg tray production line:
Pulping → Forming →Hot Press Forming→ Trimming → Drying → Packaging

The hot press molding machine is located after the forming machine and before the trimming machine. It presses the semi-formed egg trays under high temperature and pressure.
