Resin Sand Casting Machines
The resin sand casting process line (resin sand casting machines)involves mixing furan resin with sand, filling the mixed sand into sand boxes, and tamping it to shape. Afterward, the mold surfaces are coated with paints, which are burned to harden the sand molds. Once solidified, liquid iron is poured into the molds to create the desired castings.
This production line utilizes resin sand as the primary material. The process involves forming sand molds with molding machines, pouring molten iron into the molds, and ultimately producing finished workpieces. Resin sand is a mixture of natural silica sand, resin, and hardener.
The entire line consists of two key systems:
- Sand Reclamation System: Processes used sand by crushing and screening it, making it reusable.
- Molding System: Fills the mixture of resin sand into the molding machine to create sand molds for pouring.
This integrated approach ensures efficient production and sustainable use of resin sand materials.
Material
The resin sand casting process primarily uses resin sand as the molding material, complemented by alcohol-based paints.
Equipment
The process requires specialized equipment to mix the resin sand and fill it into the sand boxes.
Suitable Casting Products
Resin sand casting is ideal for producing large iron castings, typically weighing from several kilograms to several tons.
Significance of resin sand casting machines
- Environmental Impact: The process minimizes environmental pollution by enabling the recycling of more than 90% of waste sand.
- Cost Savings: Due to the smooth surface of regenerated sand particles, with uniform particle size distribution and minimal micropowder, it reduces the need for expensive resin by over 20%.
- Quality Improvement: Regenerated sand exhibits excellent thermal stability, low thermal expansion, and stable chemical properties. This enhances casting quality and reduces defects like veining and mechanical sand sticking.
Features of Furan No-Bake Resin Sand
- High Strength & Good Collapsibility: Ensures dimensional accuracy and smooth surface quality of the casting.
- Improved Fluidity: Enhances mold (core) filling, improving mold quality and labor productivity, while reducing worker effort.
- Energy Efficiency: The molds (cores) only require baking to meet pouring requirements, saving energy.
- Recyclability: Used sand can be regenerated and reused, helping further reduce production costs.

Resin Sand Molding Production Line
Foundry Machinery: China Resin Sand Reclamation Casting Machines
The resin sand molding and core-making process utilizes sand mixed with a specific amount of resin glue, which hardens naturally within a certain timeframe at room temperature. This self-hardening sand technology is widely adopted in modern foundries, with commonly used types including furan resin sand, ester-hardening alkaline phenolic resin sand, and pep-set resin sand.
Key Features:
- Self-Hardening Technology: The molding and core sand harden naturally at room temperature, with the hardening rate and final hardness influenced by ambient temperature and humidity.
- Versatile Applications: Ideal for single-piece production, small batch runs, and various medium to large-scale castings.
- Industry Usage: Widely employed in industries such as general machinery, heavy equipment, shipbuilding, locomotive manufacturing, and motorcycles.
The resin sand molding process offers excellent adaptability and is well-suited for creating high-quality molds and cores for complex castings.
