High Precision Stainless Steel Duplex Alloy Steel Investment Casting Parts

Core Processing & Customization Services

Lost Wax Investment Casting with Silica Sol

Our flagship Lost Wax Investment Casting process adopts advanced silica sol shell technology, achieving casting tolerance of CT4-CT7 (GB/T6414-1999) and VDG Merkblad P690 standards. The process supports ultra-thin wall casting with a minimum thickness of 2mm (1mm in micro-regions), round radius ≥0.3mm and internal fillet radius ≥0.5mm, and a maximum blind hole depth of 30mm (10mm diameter). Near-net-shape production minimizes material waste and subsequent machining work, reducing overall project costs while ensuring complex geometric shapes with integrated features (e.g., threaded holes, flanges) can be cast as a single unit.

Precision CNC Machining

All casting blanks are refined via professional CNC Machining services, including turning, milling, drilling, boring, threading and grinding. This post-processing step ensures the final product meets surface roughness of Ra1.6-Ra6.3, with tight dimensional accuracy for seamless assembly in machinery systems. Our CNC machining equipment is paired with professional testing tools to inspect every machined part, eliminating dimensional errors and ensuring consistency across batches.

Heat & Surface Treatment

We offer tailored Heat Treatment and surface finishing services to enhance the mechanical properties and service life of casting parts. Heat treatment options include annealing, hardening, normalizing, carburizing and aging, which adjust hardness, reduce internal stress and improve fatigue resistance for different working demands. Surface finishing solutions cover Black Oxide, black coating, Anti-Pollution Flashover Coating and Mirror Polish, providing targeted corrosion resistance, wear resistance and aesthetic effects for marine, petrochemical, medical and hardware applications.

Core Advantages & Application Scenarios

Core Competitive Advantages

High Load-Bearing Capacity: Reinforced rib designs and duplex alloy steel compositions withstand extreme forces without deformation, perfect for rugged mining, construction and heavy machinery applications.

Fully Customizable Geometry: Complex integrated shapes replace multi-part assembly, reducing failure points and assembly steps by up to 30% for improved machinery reliability.

Cost-Effective Durability: Near-net-shape casting minimizes machining waste, while professional heat treatment extends service life, delivering long-term value for industrial projects.

One-Stop Service Efficiency: In-house mold production, casting, machining and treatment ensure short lead times and seamless communication, solving the pain of multiple supplier coordination for clients.

Industrial Applications

Our casting parts are widely used in Machinery Hardware and industrial equipment across key sectors: heavy equipment linkages (excavators, loaders), industrial automation mounts (robotic arms, conveyors), power transmission components (gear housings, pulley frames), agricultural machinery (sealed bearing housings), energy sector equipment (wind turbine gearbox casings) and medical accessories—all adapted to harsh working conditions with stable performance.

One-Stop OEM Service & Quality Assurance

We provide a complete one-stop OEM Investment Casting & CNC Machining Service from project initiation to delivery: our engineering team offers design advice to optimize casting and machining efficiency for client drawings, and in-house mold production (paired with 3D printing for rapid prototyping) shortens project lead times. Quality control runs through the entire production process—3-step inspection (casting, machining, final) with professional testing equipment ensures 100% defect-free products before shipment. Backed by ISO9001:2015 and SGS certifications, we guarantee product quality and offer technical support and after-sales service for all custom projects.
