Aiwei QTJ4-40 Semi-Automatic Block Making Machine an Small and Medium-sized Machine for Making Building Material

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Block Production: Designed to manufacture hollow blocks, interlocking blocks, curbstone blocks, paving blocks, and interlock blocks using semi-automatic vibration technology.
  • Material Versatility: Processes raw materials such as concrete, cinder, fly ash, crushed stone, cement, and sand to produce durable building materials for construction projects.

Key features

  • 1. Corrosion-Resistant Metal Construction

    • With a robust steel frame and chemical-treated metal molds, you can ensure long-lasting durability in harsh outdoor environments*. The semi-automatic design resists rust and wear better than traditional all-steel models, maintaining structural integrity over years of use.

  • 2. Multi-Program Preset Controls

    • With touchscreen interface presets for hollow, interlocking, and paving blocks, you can switch production types effortlessly without manual adjustments*. This interactive design reduces setup time by up to 30% compared to fully manual systems.

  • 3. High-Output Semi-Automatic Operation

    • With a vibration-assisted compression mechanism, you can produce up to 200 bricks per hour—20% faster than manual brick-making methods*. The semi-automatic process balances speed and control for small-to-medium-scale operations.

  • 4. Versatile Material Adaptability

    • With compatibility for concrete, cinder, fly ash, and recycled aggregates, you can optimize brick strength and cost for diverse construction projects*. This flexibility outperforms single-material machines in mixed-use scenarios.

  • 5. Commercial-Grade Safety Compliance

    • With OSHA-compliant safety guards and pressure-regulated hydraulics, you can ensure operator safety during high-pressure compression cycles*. Meets industrial safety standards for continuous commercial use.
