Our industrial-grade cement block mold line is engineered for high-cycle production and dimensional accuracy across all major block formats. These molds are fabricated from heat-treated Q345B steel plate with weld zones subjected to ultrasonic inspection, ensuring structural integrity under compaction forces up to 18 MPa. The cavity surfaces receive a precision grinding treatment to maintain surface roughness below Ra 1.6 μm, which reduces concrete adhesion and simplifies demolding. For producers targeting diversified product catalogs, we offer interchangeable hollow blocks mold configurations that support cavity heights from 100 mm to 240 mm and web thickness adjustments without replacing the main frame. The paver brick mold series is designed with case-hardened stripper shoes and tungsten carbide wear tiles along the compression edge, delivering a service life exceeding 200,000 cycles when processing semi-dry mixes with river sand and crushed aggregate. Integrated vibration synchronization mounts allow the same mold set to be deployed on stationary block machines and mobile egg-laying machines. Complementary to these molds, the paving blocks molder accessory kit includes adjustable height limiters, chamfer inserts, and face mix divider plates that can be retrofitted without welding. Material certifications and dimensional inspection reports accompany every shipment, and the bolt-on segment design allows individual cavity replacement in case of localized wear.
The Cement Block Mould construction adopts a modular five-plate assembly consisting of a base plate, two side plates, and two end plates that are precisely aligned with dowel pins and secured by M20 grade 12.9 fasteners. Below is a summary of the standard technical parameters.
| Mold Type | Cavity Profile | Max Block Height | Cycle Rate | Wear Life Estimate |
|---|---|---|---|---|
| Hollow block mold | 2-core or 3-core | 240 mm | 8–12 cycles/min | 180,000–250,000 cycles |
| Solid block mold | Flat or frogged | 200 mm | 10–14 cycles/min | 200,000–300,000 cycles |
| Paver mold | Rectangular, zigzag, or I-shape | 120 mm | 12–16 cycles/min | 160,000–220,000 cycles |
| Curbstone mold | Slipform or channel | 300 mm | 5–8 cycles/min | 140,000–200,000 cycles |
| Custom mold | Per customer drawing | Up to 400 mm | Subject to testing | Project-specific validation |
Optional upgrades for the Cement Block Mould include bolt-on chamfer strips producing 2 mm, 3 mm, or 5 mm edge radii, pneumatic core pullers for deep-face textured pavers, and polyurethane-faced stripper shoes that prevent surface marking on colored face mix products. Each mold is factory-tested for parallelism and squareness using a coordinate measuring machine, with a tolerance envelope of ±0.15 mm across the pallet plane. When ordering, please specify the target block machine model, pallet size, cavity layout, and the desired block density range so the engineering team can optimize the plate thickness and stiffener rib pattern accordingly.
