In polymer sand technology, hydraulic machines of different capacities play a critical role in the production process by ensuring proper compaction, molding, and shaping of the polymer-sand mixture into durable products like tiles, pavers, or other components. Here's an explanation of their roles and how different capacities are utilized:

1. Compaction and Molding

• Purpose: Hydraulic machines apply uniform pressure to compress the heated polymer-sand mixture into molds. Proper compaction ensures the finished product's strength, density, and dimensional accuracy.

• Operation: The mixture is poured into molds, and the machine’s hydraulic system applies high pressure, enabling the material to take the desired shape and achieve a defect-free surface finish.

2. Capacity Variations

Hydraulic machines come in various capacities, typically defined by their pressing force, measured in tons (e.g., 50-ton, 100-ton, 200-ton machines). The choice of machine depends on:

• Product Size: Larger tiles or pavers require higher-capacity machines for adequate pressure and uniform compaction.

• Material Properties: Heavier and denser polymer-sand mixtures may require machines with greater force.

• Production Volume: High-capacity machines are often used for bulk production due to their ability to handle larger molds or multiple molds simultaneously.

3. Key Applications Based on Machine Capacity

• Low-Capacity Machines (e.g., 50-100 tons):

  • Suitable for small-scale production or custom-made products.

  • Ideal for lightweight items like decorative tiles or small pavers.

  • Used in R&D or pilot setups.

• Medium-Capacity Machines (e.g., 150-200 tons):

  • Used for medium-scale production.

  • Suitable for standard-sized tiles, interlocking pavers, or utility items.

  • Balances cost and productivity for small to medium industries.

• High-Capacity Machines (e.g., 300+ tons):

  • Designed for large-scale industrial operations.

  • Can handle larger molds, such as roof tiles or bulk production of heavy-duty pavers.

  • Necessary for durable and high-load-bearing products like industrial pallets or structural components.

4. Automation and Ejection

• Automatic Demolding: Hydraulic machines with ejection-based systems enhance productivity by automatically ejecting the finished product from the mold, reducing labor and cycle time.

• Consistent Quality: Higher-capacity machines with advanced controls ensure consistent pressure and temperature, resulting in uniform quality across batches.
