Green sand automatic foundry lines are ideal for mass production of small-to-medium-sized castings with relatively simple structures, primarily made of gray iron. While highly efficient and cost-effective, they have limitations in precision and complex geometries.
Suitable Casting Types:
Automotive Parts (Core Application):
Engine blocks/heads (simpler designs), crankcases, flywheel housings, transmission cases, clutch housings, intake/exhaust manifolds.
Brake drums, caliper housings, hubs, steering gear housings, differential cases, suspension arms.
Pump housings, brackets (engine/mounting).
Internal Combustion Engine & Machinery Parts:
Cylinder blocks/heads (small/medium), gearbox housings, valve/pump/compressor casings, motor end covers, flanges, pulleys.
Agricultural Machinery Components:
Tractor/harvester gearboxes, axle housings, gear chambers, brackets, counterweights.
Industrial Hardware & Fittings:
Pipe fittings (flanges, joints), low-pressure valve bodies, bases, covers, handwheels, simple structural parts.
Cookware components (stove panels, burners), hardware tools (hammer heads, wrench bodies).
Other Fields:
Simple plumbing fixtures (bases/brackets), small engineering machinery parts, elevator counterweights.
Key Limitations (Unsuitable Types):
Oversized Castings: >500kg–1,000kg (risk of mold swelling/deformation).
Complex/Thin-Wall Designs: Deep cavities, fine channels, or walls <3–4mm (prone to defects like incomplete filling or hot tearing).
High-Precision/Surface-Finish Parts: Inferior to processes like resin sand or investment casting.
Special Alloys:
Ductile Iron: Possible but requires strict sand control; prone to shrinkage/subsurface pores.
Steel: Rarely used (green sand lacks refractoriness for high temperatures).
Non-Ferrous (Al/Cu): Prefer gravity/low-pressure die casting or metal molds.
Core Advantages vs. Drawbacks:
Pros: Highest efficiency/cost-effectiveness, reusable sand, fast automation.
Cons: Limited strength/surface finish, strict sand management, unsuitable for complex/large/high-spec parts.
