Resin Coated Sand Cast Iron Casting with Smooth Surface, Precise Dimensional Tolerance and Less Post Machining Workload for Industrial Equipment

Our resin coated sand cast iron castings adopt precoated sand casting technology, supporting grey cast iron and ductile iron material grades for different industrial applications. Resin coated sand casting can deliver castings with smooth surface, precise dimensional tolerance and less post machining workload compared with conventional sand casting. These precoated sand cast machinery components are widely applied in engineering machinery, hydraulic equipment, machine tools, agricultural machinery and power transmission assemblies. We provide OEM and ODM services based on customer drawings, samples or part numbers, flexible for various sizes and complex inner cavity structures. All castings go through strict melting, molding, pouring, shakeout and cleaning processes, with full inspections including dimension checking, visual examination and material mechanical performance test before shipment. The castings own high rigidity, good wear resistance and stable mechanical properties, suitable for heavy load working environments. Secondary processing like milling, drilling, tapping and surface anti-rust treatment can be offered as requested. All items meet international casting standards, we can arrange mass batch supply with reliable lead time for global machinery manufacturers and spare parts traders. Whether you need brackets, housings, pump bodies or other complicated cast iron parts, our casting platform connects buyers with qualified foundries to realize cost-effective procurement, supporting both small trial orders and large volume production.
