Our plastic curb stone molds are specialized precision tools for manufacturing uniform, durable cement prefabricated curb stones. Designed for heavy-duty commercial and industrial construction applications, these reusable molds provide a reliable, cost-effective alternative to cumbersome steel molds.
Wangzu operates a complete digital quality control system covering every stage from raw material inspection to finished product testing. Every batch of molds undergoes rigorous performance verification to ensure consistent quality and long service life, making them ideal for large-scale infrastructure projects and high-volume precast production facilities.
Primary material is food-grade virgin engineering polypropylene (PP), with optional ABS plastic available for specialized high-impact requirements. This material offers exceptional properties tailored for construction use:
Non-toxic, odorless and 100% recyclable, compliant with global environmental standards
High tensile strength, excellent stiffness and superior hardness
Heat resistance up to 100℃, suitable for use in most climate conditions
Outstanding anti-aging properties, maintaining performance over repeated use
High electrical insulation and moisture resistance
All molds are manufactured using state-of-the-art injection molding technology with strict process control:
Quantitative feeding of raw materials to ensure consistent material composition
High-temperature melting and plasticizing at 200-280℃ for uniform material flow
Precision pressure injection into precision-machined mold cavities
Controlled cooling to prevent warping and ensure dimensional accuracy
Automatic mold lifting and finishing inspection
This fully monitored process guarantees a cavity size error of ≤ 0.5mm, ensuring every curb stone produced meets exact engineering specifications.
Our molds feature a convex letter-shaped single parting surface design, optimized for easy demolding and structural integrity. This design supports production of various complex curb stone profiles, including arcs, chamfers, curved edges and custom decorative patterns to meet diverse project requirements.
Every feature of our molds is designed to solve the most common pain points of precast concrete producers:
Ultra-fast demolding: Smooth, non-porous cavity surface minimizes concrete adhesion. Demolding time is only 1/4 of steel molds, allowing for multiple production cycles per day
Lightweight and labor-efficient: 65-80% lighter than equivalent steel molds, easily moved by a single worker. Eliminates the need for cranes or heavy lifting equipment, reducing labor costs by up to 50%
Long service life: Can be reused for -100 concrete pouring cycles with proper maintenance (regular application of demolding agent)
Low total cost of ownership: 30-50% lower initial cost than steel molds, with no rust prevention, painting or frequent repair requirements
