What is a Furan Resin Sand Molding Line?
A furan resin sand molding line is a type of chemical sand casting process where furan resin is used as the binder to harden silica sand. The system forms molds for pouring molten metal into desired casting shapes. The process is known for:
- Excellent mold strength
- High dimensional accuracy
- Smooth surface finish
- Ability to mold large and complex parts
How It Works
The basic steps in a furan resin sand molding process include:
- Sand Preparation
Fresh or reclaimed sand is mixed with furan resin and an acid catalyst in a continuous mixer. - Mold Forming
The resin-bonded sand is compacted into a pattern or mold box. Chemical reactions harden the mold quickly at room temperature. - Core Setting and Assembly
Cores, if needed, are placed inside the mold cavity for complex internal geometries. - Pouring and Cooling
Molten metal is poured into the mold. After cooling and solidification, the mold is broken away. - Shakeout and Sand Reclamation
Sand is separated from the casting and sent through reclamation to be reused.
Key Components of a Furan Molding Line
- Continuous Sand Mixer: Mixes sand, resin, and acid catalyst uniformly.
- Molding Station: Manual, semi-automatic, or fully automatic stations for mold making.
- Mold Compaction System: Vibrating tables or pressing devices ensure mold integrity.
