Choosing the right sand casting manufacturer is essential for consistent quality, precision, and cost efficiency. When evaluating partners, consider the following:

  • Process Capability – Greensand, no-bake (resin-bonded), shell molding, and CO₂; in-house coremaking; 3D-printed cores/patterns where applicable.
  • Material Range – Aluminum (e.g., 319, 356/357, 535), gray/ductile iron, carbon & low-alloy steels, stainless, bronze & brass.
  • Part Size & Weight Window – Minimum/maximum casting envelope, single-pour weight, and gating strategy for your geometry.
  • Dimensional Tolerances & Surface Finish – Typical sand casting tolerances; achievable Ra; draft, fillet, and wall-thickness guidance.
  • Pattern Tooling & Lead Time – Pattern type (wood/urethane/metal/3DP), maintenance policy, expected lifespan, and build schedule.
  • Core Complexity – Capability for intricate cores, core assembly, and core prints; venting and wash compatibility.
  • Heat Treatment & Finishing – T6/T7 for aluminum, normalizing/annealing for iron & steel, shot blast, vibratory finishing, impregnation, coating/painting.
  • Machining & Integration – In-house CNC machining, fixturing, and CMM verification to deliver fully finished parts.
  • Quality & Certifications – ISO 9001/IATF 16949, PPAP, APQP, FMEA; NDT (X-ray, UT, MT, PT), spectrographic analysis, sand control.
  • Commercials – MOQs, unit pricing breakdown (metal, melt, mold, cores, finishing, machining), tooling amortization, payment terms.
  • Program Management – DFM/DFX support, sampling plans, first-article validation, and sustained on-time delivery performance.

Industries That Rely on Sand Casting

Sand casting is critical to sectors that require durable, precise, and scalable metal components:

  • Industrial & Heavy Equipment – Gear housings, pump bodies, bearing caps, brackets
  • Automotive & Commercial Vehicle – Housings, manifolds, brake components, knuckles
  • Agriculture & Construction – Counterweights, covers, hubs, structural castings
  • Energy & Power – Turbine housings, valve bodies, compressor components
  • Oil & Gas / Fluid Handling – Valve/valve bodies, impellers, pump casings
  • Marine – Propellers, strainers, deck hardware (bronze/brass)

What is Sand Casting?

Sand casting is one of the oldest and most adaptable metal casting methods. It involves creating a mold cavity in sand, pouring molten metal into the mold, and breaking the mold away once the metal solidifies.

This process supports a wide range of metals and is especially cost-effective for low to medium-volume production, large parts, and prototyping. With proper pattern design and core placement, sand casting can produce both simple and complex geometries.

Modern sand casting combines traditional techniques with advanced simulation software and process control, resulting in greater consistency, dimensional accuracy, and surface quality than ever before.
