Product Details ofPaving Block Moulds
paving block moulds
In the world of blocks production,paving block moulds are often the most overlooked yet crucial component. The quality of a brick-whether it is square and durable, has precise and uniform dimensions, and resists chipping and breaking-ultimately depends on the professionalism of mould design and manufacturing. A complete set of block moulds includes multiple parts such as the upper mould, lower mould, press head, and cavity inserts. The structure of moulds varies greatly depending on the type of brick (e.g., hollow bricks, interlocking bricks, kerb stones, permeable bricks). To accommodate various brick types, we adopt a modular design approach. Customers can quickly switch between different modules based on production needs, significantly enhancing the versatility and efficiency of the moulds. Moreover, our moulds are compatible with multiple brands of brick-making equipment, easily adapting to different block machine production lines.
Specialized Technical Capabilities
Beyond standard paving block moulds production, we excel in complex structural solutions that challenge conventional manufacturing:
Horizontal Core-Pull (Draw-Bar) Moulds: Our paving block moulds engineering team designs sophisticated horizontal pulling mechanisms enabling undercut geometries and internal voids impossible with conventional fixed-core systems. These specialized paving block moulds create hollow units with superior strength-to-weight ratios and enhanced thermal performance.
Adjustable Curb Stone Moulds: Live-plate technology allows rapid profile modification without complete tooling replacement. These versatile paving block moulds adapt to varying curb heights, batter angles, and reveal dimensions from a single base configuration.
Integrated Cavity Machining: For grass-grid pavers and ecological slope protection units, our paving block moulds incorporate monolithic cavity machining combining beam structures, lifting anchors, and planting voids in unified precision-manufactured assemblies. This integration eliminates tolerance stack-up and ensures perfect alignment between structural and functional elements.
Two Decades of Quality System Development
Nearly twenty years of continuous improvement has established our comprehensive quality management system. This maturity translates into paving block moulds products with proven process technology and consistently reliable quality. From raw material verification through final inspection, every paving block moulds production stage follows documented protocols ensuring traceability and performance validation. Our vacuum-degassed alloy steel preparation, multi-directional forging, and advanced heat treatment processes guarantee paving block moulds service life exceeding 80,000-100,000 cycles.
Interlocking Paver block Mould Technical Highlights
Choose the plan that suits you best.
Mould frame
low-carbon alloy, high-strength carburizing steel → superior wear resistance after case-hardening
Die clearance
0.5–0.6 mm → ensures clean demolding and sharp edges on every grass slot
Suspension plates
imported high-strength structural steel → long service life, minimal deformation
Mould cores
wire-cut EDM machining → perfectly square corners and mirror-smooth sidewalls for both aesthetic appeal and reliable function
