Small brick machine mold

Small Brick Machine Mold: Precision Engineering for Reliable Brick Production

For small-scale construction projects and niche manufacturing needs, the right tooling can determine both output quality and operating costs. Our colored brick machine mold series delivers vibrant, consistent face bricks without secondary coloring processes, while the unburned brick machine mold allows eco-friendly, cement-stabilized block production using local soils and industrial by-products. For contractors integrating these molds into automated lines, our road brick machine solutions and dedicated colored brick machine packages offer turnkey compatibility. Every mold is CNC-machined from hardened alloy steel, ensuring interchangeability across major press brands and a service life exceeding 800,000 cycles under normal conditions. Below are the core technical specifications that enable such performance.

  • Mold body material: Hot-forged 45# carbon steel with vacuum quenching to HRC 48-52 on wear surfaces
  • Inner cavity plating: Hard chrome, 0.03–0.05 mm thickness, reducing friction and preventing corrosion
  • Hydraulic tolerance: ±0.1 mm across all critical dimensions, ensuring tight form fit on press platens
  • Brick dimension range: Length 200–400 mm, width 100–200 mm, height 50–200 mm; custom sizes on request
  • Applicable pressure: Up to 25 MPa static, suitable for dense concrete and fly ash mixes
  • Weight (standard single-mold): 28–65 kg depending on cavity layout, allowing manual changeover with lifting aid
  • Interchangeable wear inserts: Tungsten carbide wedges at high-abrasion zones, replaceable in under 30 minutes

Each assembly undergoes coordinate measuring machine (CMM) inspection before shipment, and the hard chrome layer is tested for uniformity using X-ray fluorescence. Bolt patterns and guide-bushing locations are documented with 2D drawings provided in the shipment dossier, simplifying installation. Lubrication grooves and a sealed edge design prevent slurry ingress, extending mould life even when processing abrasive mixtures like crushed granite aggregate.


When selecting a Small Brick Machine Mold for continuous production runs, attention to detail in the clamping system and ejection mechanism pays long-term dividends. The Small Brick Machine Mold comes standard with a quick-release T-slot base that aligns with most press beds, cutting setup time to under 15 minutes. Hardened steel stripper shoes travel within phosphor bronze bushes to eliminate metal-to-metal contact during the ejection stroke, while external wear indicators let operators schedule maintenance without disassembly. Multiple cavity configurations allow simultaneous production of full bricks, half bricks, and paving blocks in the same cycle—ideal for developers who need on-site variety without stocking multiple molds. The precision-ground parting line ensures a clean, burr-free finish on every brick, reducing the need for secondary trimming. By switching between the colored-brick and unburned-brick variants of the Small Brick Machine Mold, producers can quickly respond to regional demand for decorative landscaping products or affordable housing materials, all while keeping inventory light. Whether retrofitting an existing press or commissioning a new line, the Small Brick Machine Mold offers a balance of durability, dimensional accuracy, and ease of use that directly improves per-shift productivity.
