Equipment Overview:

The GB-MM100 Hot Melt Machine is a specialized device designed for recycling waste foam (such as EPS, EPP, etc.). Its core function is to efficiently convert bulky, hard-to-handle foam waste into high-density, easy-to-transport and store molten blocks (commonly known as "cakes" or "blocks") through a series of mechanical and thermal processes.


key components:

1.Frame: Forms the main structural framework and support.

2.Feed Hopper: Receives and temporarily stores waste foam feedstock.

3. Crushing System: Located below the feed hopper, responsible for initially breaking large foam pieces into smaller fragments.

4. Extrusion System: The core component, consisting of one screws. It receives the crushed foam fragments, conveying, compressing, and generating friction heat via screw rotation, ultimately extruding the molten material.

5. Heating System: Integrated externally around the extrusion system, providing auxiliary thermal energy to ensure the material fully and uniformly melts and plasticizes within the screw.

6. Electrical Control System: Includes the power distribution cabinet, operator panel (buttons, switches), temperature controllers, motor drives, etc., responsible for power supply, logic control, parameter setting, and monitoring.


Operating Procedure:

Switch on the power, check whether there is any exception,press the heatingswitch,heat the temperature forhalf an hour after reaching theset value,then press the startingmotor switch to start the machinerunning;after running for5minutes,then put in the wastefrom the inlet. The waste foam iscrushed into pieces,screw heatedand extruded.


Equipment Features:

1. Frame and Structural Features:

Fabricated from Profiles: The main frame is constructed from high-strength structural steel profiles (e.g., square tubes, channels, I-beams) welded together.The robust welded frame provides high rigidity and stability, effectively withstanding vibrations and impact loads during crushing and extrusion, ensuring long-term smooth operation.


2. Temperature Control System Features:

  •  For first temperature control :Set Range: 150°C - 200°C. Near the feed inlet, material is in solid fragment form. The relatively lower setting prevents premature softening and sticking ("bridging") at the inlet causing blockages, while providing sufficient heat to initiate softening.

  •  For second temperature control:Set Range: 200°C - 250°C. This is the core zone for intense compression, friction heating, and melting/plasticization. The highest temperature setting provides ample external heat, ensuring material melts fully and uniformly here, achieving good plasticization and venting any trapped gases or volatiles.

  • For third temperature control:Set Range: 180°C - 200°C. Near the extruder die. Material is largely melted and plasticized. The slightly lower setting (vs Zone 2) allows the melt to cool slightly, increasing viscosity and strength. This ensures stable shape and smooth surface of the extruded strips/blocks, preventing breakage or excessive deformation, and avoids material degradation (charring) from excessive heat.

  • Process Advantage: This zoned independent temperature control allows precise, flexible adjustment of heat input based on the material's physical state (solid -> softening -> melting -> homogenizing) and thermal requirements at different points along the screw. This optimizes melting efficiency, plasticizing quality, and prevents issues like overheating degradation or insufficient plasticization, making it crucial for the final "block" quality.
