315 Ton Four Pillar Hydraulic Press Machine
The 315-Ton Four-Column Hydraulic Press line integrates auto-loading, extrusion mixing, and water-cooled molding to transform recycled waste plastics and foundry sand into durable composite floor slabs. This automated setup optimizes heat distribution, high-pressure compaction, and rapid chilling to produce high-strength, weather-resistant snow-melting slabs efficiently.
Use Case
The integrated 315-Ton press line melts, mixes, and high-pressure compacts waste plastics and sand into void-free composite slabs, while an industrial chiller rapidly cools the mold from 200°C to 60°C for fast demolding.
- Core Applications: Heavy-duty outdoor paving, snow-melting pedestrian walkways, anti-skid driveways, and sustainable urban infrastructure solutions.
- Material: 70% post-consumer waste recycled plastics, 30% foundry waste sand, along with targeted color pigments and protective UV additives.
- Products Processed: Multi-color, waterproof, impact-resistant, and lightweight plastic-sand composite snow-melting floor slabs.
Why 315 Ton Hydraulic Press
- High Compaction Density: Delivers up to 315 tons of clamping force to squeeze out air pockets, eliminating internal voids and ensuring uniform structural strength throughout the dense sand-plastic matrix.
- Precise Slab Geometry: Holds precise dimensional tolerances across large surface areas, ensuring perfectly flat, interlockable floor slabs with consistent load-bearing capability.
- Optimized Thermal Transfer: Maintains rigid surface contact with the water-cooled mold during the cooling cycle, maximizing heat transfer efficiency to cure the molten composite quickly without warping.

04 — Product Application
Where Plastic Sand Composite Snow Melting Floor Slabs Are Used
Plastic sand composite snow melting floor slabs provide a durable, eco-friendly heating solution designed to automatically prevent ice build-up in critical foot and vehicle traffic zones. They replace traditional energy-intensive snow removal methods by integrating efficient thermal technology directly into robust outdoor paving.
Industry Applications
Urban Pedestrian Walkways and Sidewalks
These slabs keep high-foot-traffic city pathways, plaza walkways, and public building entrances entirely ice-free during severe winter conditions. Their slip-resistant surface prevents pedestrian falls while eliminating the need for harsh chemical deicing salts.
Commercial Transit Platforms and Bus Stops
Installed across railway platforms, bus boarding zones, and airport passenger concourses to maintain clear boarding environments. The continuous snow-melting capability prevents dangerous ice packing caused by heavy transit commuter traffic.
Residential Driveways and Outdoor Steps
Ideal for home entrances, steep driveway inclines, and exterior staircases where manual shoveling is difficult or hazardous. They provide immediate heat distribution to maintain clear access routes without damaging surrounding landscaping.
Industrial Loading Docks and Logistics Parks
Deployed in high-capacity freight yards and warehouse loading bays to ensure uninterrupted material handling operations. By keeping ramp surfaces free of frost and slush, they minimize heavy vehicle slippage and operational downtime.
