Product DescriptionProduct DescriptionProduct Description of Precision Sand CastingsWe specialize in manufacturing high-precision, complex-geometry sand castings using advanced processes such as resin sand, sodium silicate sand, shell sand, and cold-box/hot-box core making. Integrated with digital simulation (CAE) and smart foundry technologies, our castings deliver exceptional dimensional accuracy, smooth surface finish, and sound internal structure—widely used in aerospace, power generation, rail transit, industrial pumps & valves, and construction machinery.Our "Precision Sand Casting" goes beyond conventional sand casting. Through precise pattern design, strict process control, and full-process quality traceability, we achieve sand casting accuracy close to investment casting, especially suitable for medium to large complex components (5kg – 20 tons per piece). This offers high performance at a significantly lower cost.Core Manufacturing ProcessesProcess TypeTechnical FeaturesResin Sand MoldingExcellent dimensional stability for complex and large parts; casting tolerance up to CT8–CT9.Shell Core MakingHigh-strength, smooth-surface cores with low gas generation—ideal for precision internal cavities.Cold-Box / Hot-Box CoreFast curing, high dimensional accuracy—suitable for mass production of complex cores.Lost Foam CastingNo parting line; enables extremely complex geometries; surface roughness Ra 12.5–25μm.Numerical Simulation (CAE)Optimizes gating system via ProCAST/MAGMA to reduce shrinkage, porosity, and defects.Typical ApplicationsAerospace: Engine brackets, housings, connectorsEnergy: Valve bodies, pump casings, turbine housings, wind turbine gearboxesRail Transit: Brake components, bogie parts, gearbox housingsIndustrial Pumps & Valves: Impellers, bonnets, bodies, sealsConstruction Machinery: Excavator teeth, track pads, slewing bearing housingsCompany ProfileQingdao Dingli Machinery Co., Ltd.Qingdao Dingli Machinery Co., Ltd. is a company specializing in the production of casting machinery equipment.
