Chifine
Qingdao Chifine Machinery specializes in customized cast nodular iron (ductile iron) crane spare parts using resin coated sand casting technology. Our core materials include grey iron, ductile iron, and optional aluminum/copper alloys, with product compliance to GB, ASTM, SAE, ISO, EN, DIN, and JIS standards. We cater to industries relying on heavy-duty crane systems, offering parts with CT9-CT12 casting tolerance and a weight range of 0.5kg - 100kg (for steel/iron parts) to ensure compatibility with diverse crane models.
High-Strength Materials: Focus on nodular iron (ductile iron) and grey iron, with options like A356-T6 aluminum alloy and copper alloys (e.g., 65-45-12, 80-55-6) for specialized load-bearing needs. Nodular iron provides excellent tensile strength and impact resistance, critical for crane safety.
Precision Resin Sand Casting: Resin coated sand casting ensures smooth part surfaces, reduced porosity, and consistent mechanical properties. This process minimizes casting defects, making parts suitable for high-stress crane applications.
Comprehensive Heat Treatment: Services include annealing, carbonization, tempering, normalization, and surface tempering. These treatments enhance part hardness and fatigue resistance, allowing parts to withstand repeated heavy loads in crane operation.
Diverse Surface Protection: Options like oiled rust-proofing, electroplating, hot dip galvanizing, nickel/chrome plating, and powder coating. These protections extend service life in outdoor or dusty crane operating environments.
Professional Team Support: Four dedicated teams (Project, Engineering, QC, Warehouse) manage customer service, R&D, quality control, and logistics. This division ensures seamless order execution from inquiry to delivery.
For cranes used in construction sites or mines, we produce high-load bearing components such as hooks and pulleys using nodular iron with annealing treatment. Annealing reduces internal stress, ensuring parts resist impact and heavy loads—critical for lifting construction materials or mining ores.
Railway and port cranes operate in humid, corrosive environments. We apply hot dip galvanizing or nickel plating to parts like crane wheels, forming a protective layer that prevents rust and reduces maintenance frequency. This ensures cranes maintain stable operation in coastal or railway yard conditions.
Agricultural cranes require lightweight yet durable parts; we use A356-T6 aluminum alloy for components like boom connectors, reducing crane weight while maintaining strength. For industrial cranes operating indoors, we provide powder-coated parts that resist dust accumulation and maintain a clean appearance.
We are proficient in Pro/E, AutoCAD, and Solidworks to convert customer drawings into production-ready models. Our engineering team optimizes part structure for casting efficiency—for example, adjusting wall thickness to avoid shrinkage defects and adding fillets to enhance stress resistance.
Our production facility includes electric furnaces and cupola furnaces for material melting, sand mixing machines for resin coated sand preparation, shot blast chambers for surface cleaning, and CNC lathes/boring machines for precision machining. This equipment ensures consistent part quality and machining accuracy.
We use tools like CMM (Coordinate Measuring Machines) to verify dimensional accuracy, hardness testers to check material hardness, and metallographic microscopes to analyze internal material structure. These tests confirm that parts meet casting tolerance and mechanical property requirements.
With over a decade in metal casting, our team provides technical advice to optimize part designs for cost and performance. We recommend material selections and process adjustments based on crane type, load capacity, and operating environment.
We accept low to high-volume orders, from a few spare parts for crane maintenance to large batches for new crane production. We also offer flexibility to adjust specifications based on customer feedback, ensuring final products meet expectations.
We provide custom packaging using plywood cases or pallets to prevent damage during shipping. Our logistics team partners with reliable carriers to ensure parts arrive intact and on time, whether delivered to domestic factories or international customers.
