block molds

Our comprehensive line of block molds is engineered to deliver precision and durability across multiple concrete product applications. The range includes a high-performance cement block mould ideal for solid load-bearing walls, a versatile cement block mold that adapts to various aggregate mixes and compaction cycles, a lightweight hollow blocks mold configured for rapid production of voided units, and a specialized paver brick mold designed to create consistent interlocking shapes with crisp edges. Every mold is built inside a rigid steel frame, heat-treated for uniform hardness, and finished with a low-friction coating that minimizes wear while assisting fast demolding. Whether producing standard rectangular blocks, decorative pavers, or complex hollow sections, these molds maintain dimensional accuracy even under high-frequency vibration and heavy compaction pressure.


The <产品名字> are manufactured using thick-gauge structural steel plate that undergoes double stress-relief treatment before CNC machining. This process removes residual tension, keeping the mold block faces perfectly flat and parallel over thousands of production cycles. Core pins and divider plates are fabricated from alloy steel with hardened surfaces, and the cavity walls are polished to a mirror-grade finish to reduce sidewall friction. Every unit is shipped with a calibrated inspection report that documents cavity dimensions, parallelism, and surface hardness readings.

  • Frame material: Q345 low-alloy structural steel with 8–12 mm wall thickness
  • Wear components: Cr12MoV or SKD11 tool steel with HRC 58–62 surface hardness
  • Surface treatment: electrophoretic anti-corrosion coating plus PTFE-impregnated seal layer
  • Joining method: full-penetration welding with post-weld vibration aging
  • Vibration compatibility: rated for 2,800–4,200 rpm table vibration without fatigue cracking
  • Demolding clearance: 0.15–0.25 mm per side, adjustable upon request
  • Customization: cavity count, block shape, logo engraving, and mounting plate pattern can be tailored

Production-grade steel plates are laser-cut to minimize edge deformation, and every weld seam passes ultrasonic testing on critical joints. The semi-automatic polishing station ensures cavity surface roughness stays below Ra 0.4 µm. These molds integrate directly with egg-laying concrete block machines, stationary multi-layer presses, and hydraulic paver lines. Wear plates are bolted rather than welded at high-abrasion zones so that individual parts can be swapped without discarding the entire mold. The balanced design distributes compaction energy evenly across all cavities, which leads to uniform density and strength in every product. Operating with standard pallet sizes of 1,100×500 mm or 1,400×700 mm, the molds achieve consistent block height tolerance of ±0.5 mm after 150,000 cycles. Routine maintenance involves cleaning the cavity surface with a copper brush and applying a release agent mist every 500 cycles. Under normal conditions, the mold body delivers over 10 years of service before major refurbishment.
