EPDM Vulcanizing Press Machine / EPDM Rubber Sheet Making Machine
Our EPDM Rubber Sheet Making Machine represents a complete production line solution for manufacturing high-quality EPDM sheets used in roofing, pond liners, gaskets, and automotive seals. This sophisticated system transforms raw materials into finished products through a carefully engineered multi-stage process.
Core Production Line Stages & Machinery
1. Raw Material Preparation & Mixing
The process begins with precise weighing of EPDM raw polymer, carbon black, oils, plasticizers, curing agents, and other additives. These materials are then loaded into specialized mixing equipment.
Primary Machinery: Weighing Scale, Internal Mixer (Banbury Mixer) or Open Two-Roll Mill
Process: Intensive batch mixing ensures uniform compound distribution, with the two-roll mill also serving to sheet out the mixed material
2. Sheet Formation / Calendering
This critical stage shapes the mixed compound into continuous, uniform sheets using two primary methods:
A. Calender Line - Ideal for consistent, wide, thin-to-medium thickness sheets
Key Equipment: Multi-roll Calender (L-Type, Z-Type, or Inclined Z-Type)
Features: Precision-heated rolls with adjustable gap control for thickness determination
Supporting Systems: Feed conveyor, roll heating/cooling systems, liner application unit
Reinforcement: For roofing membranes, includes polyester or fiberglass scrim insertion and lamination capabilities
B. Extrusion Line with Calendar or Roller Die - Suitable for thicker sheets or continuous vulcanization
Key Equipment: Rubber Extruder with wide flat die (sheet die or T-die)
Downstream Processing: Calender rolls or polishing roller train for final thickness calibration and surface finishing
3. Vulcanization (Curing)
EPDM undergoes vulcanization to develop its essential elastic properties, with method selection based on product requirements:
Rotary Hot Air Vulcanizer (Continuous): Sheet travels through multi-zone heated oven on conveyor system - ideal for continuous roofing membrane production
Press Vulcanization (Batch): Cut sheets cured in Flat-Bed Platen Press between heated plates - suitable for thicker sheet goods
Autoclave (Batch): Steam-heated pressure vessel curing for drum-wrapped or tray-placed sheets
4. Cooling, Inspection & Winding/Cutting
Cooling: Large water-cooled drums rapidly reduce sheet temperature
Note: Comprehensive due diligence recommended for supplier selection
An EPDM Rubber Sheet Making Machine represents a sophisticated production system where configuration depends entirely on sheet type (reinforced vs. pure, solid vs. foam), quality standards, and production volume requirements. Define your precise product specifications to guide optimal machinery selection.
