I. Standard Model and Tonnage (Commonly Used)

• XLB-D 600*600 / 1.00MN (100 tons)
  • Molding Force: 100 tons (Suitable for most rubber blocks, mold cavity pressure is approximately 2.8 MPa)
  • Hot Plate Dimensions: 600 * 600 mm
  • Number of Hot Plate Layers: 2 layers (three plates with two layers) or 4 layers
  • Plunger Stroke: 300–400 mm
  • Hot Plate Spacing: 125–200 mm (Adjustable)
  • Heating: Electric heating, power per layer is approximately 3.0–4.5 kW
  • Temperature: Room temperature to 200–250℃
  • Temperature Control Accuracy: ±1~2℃
  • Structure: Four-column type (Most commonly used)
• XLB-D 600*600 / 1.60MN–2.00MN (160–200 tons)
  • Suitable for large-sized, high-density, thick rubber blocks, or multi-cavity high-capacity molds
  • Greater clamping force, denser pressing, avoiding glue shortage and bubbles

II. Recommended Configuration for Rubber Blocks

• Number of Layers: Prefer 2 layers (standard) or 4 layers (efficient)
  • 4-layer machine: Can place 4 sets of molds at once, production capacity doubles
• Pressure:
  • Common rubber blocks (NR/SBR/EPDM): 100 tons is sufficient
  • High hardness, thick products, fluorine rubber blocks: Recommended 160–200 tons
• Heating Method: Electric heating (Precise temperature control, simple installation, low maintenance)
• Control:
  • Semi-automatic: Manual + automatic timing, exhaust, holding pressure, mold opening
  • Fully automatic (recommended): PLC + touch screen, automatic cycle, formula storage
• Additional Functions:
  • Automatic exhaust (3–5 times): Reduces rubber block bubbles
  • Automatic ejection: Convenient for taking parts, improves efficiency
  • Fast and Slow Hydraulic Cylinders: Fast mold closure, slow pressure increase, protects molds

III. How Large Rubber Blocks Can Be Made with 600*600?

• Single rubber block: ≤500*500mm (leave 50mm on each side for mold placement / exhaust)
• Multi-cavity in one mold: For example, 100*100mm block → One mold can hold 36 blocks (6*6)
• Height: ≤120–150mm (based on layer spacing of 125–200mm)

IV. Price Reference (2026)

• 100 tons 600*600 Semi-automatic: $5,000 - $8,000
• 100 tons 600*600 Fully automatic (PLC): $6,000 - $9,000
• 160–200 tons 600*600: $9 - $150,000 (depending on configuration)

V. Selection Points (For Rubber Blocks)

• According to mold size: Hot plate is 50mm larger than each side of the mold +
• According to product thickness: Layer spacing > product thickness by 30% +
• According to hardness / material: High hardness, thick wall → Tonnage is increased by 1.2–1.5 times
