0.1-100kg Steel Cast Construction Part encompasses a versatile range of precision-engineered components that form the critical infrastructure of modern construction machinery and structural systems.
Chifine
From small brackets (0.1kg) to large gearboxes (100kg), these castings deliver consistent performance across diverse applications, including crane booms, concrete mixer drums, scaffolding connectors, and machinery frames. Our ability to produce such a broad weight range—unmatched by many foundries—makes us a one-stop supplier for construction OEMs seeking consolidated supply chains and uniform quality standards. These steel cast parts replace traditional fabricated weldments with 30% weight reduction and improved structural integrity, while our ISO 9001:2015 certification ensures compliance with global construction safety standards, including EN 10204 3.1 material certification for critical load-bearing components.
The 0.1-100kg construction parts are manufactured using a range of high-performance steels tailored to specific weight and application requirements:
• Low-carbon steel (ASTM A27 Grade N-1) for lightweight components (0.1-10kg) requiring high weldability, with carbon ≤0.25% and tensile strength of 40-55 ksi (275-380 MPa).
• Medium-carbon steel (ASTM A27 Grade 65-35) for medium-weight parts (10-50kg) needing balanced strength and ductility, featuring 0.25-0.35% carbon and 65 ksi (450 MPa) minimum tensile strength.
• High-strength alloy steel for heavy components (50-100kg) such as structural brackets, alloyed with manganese (1.0-1.5%) and chromium (0.5-1.0%) to achieve 80 ksi (550 MPa) tensile strength and enhanced wear resistance.
All materials undergo appropriate heat treatment—annealing for machinability, normalizing for uniformity, or quenching and tempering for high strength—with mechanical properties verified through destructive testing of production coupons.
Our foundry equipment, including automated molding lines and large-format sand casting cells, handles parts from 0.1kg (precision brackets) to 100kg (structural housings), eliminating the need for multiple suppliers and ensuring consistent quality across component sets.
Advanced casting simulation software (MAGMAsoft) optimizes gating and riser design, reducing porosity to ≤1% in critical sections. Ultrasonic testing confirms internal soundness, with load-bearing components exceeding 120% of design load in proof testing.
Depending on weight and complexity, parts achieve ISO 8062 CT9-CT12 tolerances, with linear dimensions controlled to ±0.5 mm for parts up to 500mm and ±1.0 mm for larger components. This precision reduces machining requirements by 20-30% compared to conventional castings.
Options include primer coating for immediate painting, hot-dip galvanizing for corrosion protection in outdoor applications, and phosphate conversion coating for enhanced paint adhesion. All finishes meet industry standards such as ASTM B633 for zinc plating.
Our custom service capabilities are designed to support the entire product lifecycle, from concept to mass production. For prototyping, we offer rapid sand casting with 3D-printed patterns, delivering first articles in 2 weeks for design validation. Engineering support includes DFM (Design for Manufacturability) analysis to optimize part geometry for casting efficiency, potentially reducing production costs by 15-20%. Material selection is tailored to application requirements, with options for wear-resistant alloys (high-chromium cast iron) for abrasive environments and corrosion-resistant grades (weathering steel) for outdoor structures. Production volumes are highly flexible, supporting 50-piece prototypes, 1,000-piece pre-production runs, and 10,000+ piece annual production with consistent lead times. Quality documentation includes material certificates, dimensional reports, and non-destructive testing records, with optional FAT (Factory Acceptance Testing) for critical components. We also provide just-in-time (JIT) delivery programs and vendor-managed inventory to streamline our clients’ supply chains, ensuring construction parts are available when needed to keep projects on schedule.
