Browse our top-tier precision components, manufactured to meet strict international tolerances using modern processes including Silica Sol Casting, Zinc Plating, and CNC Machining.
Ningbo Yinzhou Haochu Machinery Manufacturing Co., Ltd. (established in 2013) is a modern manufacturing enterprise specializing in the research, production, and service of casting and forging technologies. Driven by innovation, the company is committed to delivering high-precision machining solutions for industries such as automotive parts, agricultural machinery, valves, and industrial automation.
Over the past decade, we have optimized our supply chains and engineering layouts to deliver small machine parts with tolerances as close as 0.02mm. Our deep material expertise allows us to cast and machine complex geometries in carbon steel, 45# steel, alloy steel, and 6061 aluminum, with tailored post-treatments including zinc plating, anodizing, and anti-rust coatings.
By blending mechanical design expertise with certified quality management system, we minimize lead times, lower material waste, and guarantee structural integrity from prototypes to large-scale wholesale production runs.
We balance modern equipment with tight quality controls to satisfy stringent engineering blueprints. Our technical infrastructure is engineered to handle custom requirements for heavy-industry components and lightweight architectural components alike.
Our operation is built on skilled talent: over 30% of our workforce consists of certified technical staff, supported by 10 senior inspectors who maintain a 99.5%+ product qualification rate across all assembly lines.
Equipped with 40+ modern production units including multi-axis CNC machining centers, automated CNC lathes, and Coordinate Measuring Machines (CMM) to enable an annual output value exceeding RMB 30 Million.
Operating under strict ISO 9001 certifications, we enforce a strict three-tier inspection system (initial raw material inspection, process routing control, and final outbound audit) to ensure zero defect delivery.
Modern global procurement requires more than just low unit costs; it demands supply chain adaptability, risk mitigation, and digital tracking. At HAOCHU, we integrate traditional metal processing with digital casting and smart machining loops (Factory 4.0 principles).
By housing silica sol casting, forging, and secondary CNC precision machining in a unified regional ecosystem in Ningbo, we eliminate inter-factory transport delays, scrap miscommunications, and secondary processing alignment errors.
This vertical alignment enables us to optimize material utilization, reduce overall energy consumption, and guarantee structural integrity. For global buyers, this translates to stable pricing matrices, predictable production timelines, and complete material traceability back to the original heat number.
"Precision Crafts Quality, Innovation Defines the Future" - we deliver robust components for demanding industrial and engineering environments worldwide.
To stay at the forefront of the manufacturing industry, HAOCHU constantly advances its technical capabilities. Here is our strategic roadmap for integrating smarter systems and sustainable manufacturing processes.
Developing specialized micro-CNC machining processes designed for miniature medical, aerospace, and electronics components requiring tight tolerances down to 0.005mm.
Integrating high-efficiency metal 3D printing (DMLS) with CNC post-processing to create optimized geometries that are impossible to machine using traditional subtractive techniques alone.
Transitioning toward carbon-neutral casting operations by utilizing 100% recycled scrap metals, closed-loop water treatment systems, and low-emission electric induction furnaces.
We are committed to becoming a global innovation leader in high-end equipment manufacturing, driving precision engineering with smart technologies and empowering the future of industry through sustainable development. By advancing intelligent, digital, and green technologies, we aim to establish a world-class benchmark in machinery manufacturing that integrates R&D, production, and service.
Guided by our core philosophy of "Precision Crafts Quality, Innovation Defines the Future," we foster efficient industry collaboration and elevate customer value by delivering smarter, more reliable solutions for global industries. Upholding green manufacturing principles, we build a low-carbon, resource-efficient ecosystem, fulfill social responsibilities, support employee growth, and drive community prosperity to achieve our ultimate mission: "Intelligently Crafting a Better World."

Different operating environments require specific mechanical characteristics. We design custom parts to withstand high mechanical loads, thermal fatigue, and chemical degradation.
We supply lightweight structural components, engine valve mounts, and heavy-duty drivetrain couplers. Utilizing heat-treated 45# steel and high-tensile alloy compositions, our components withstand constant vibration and high mechanical loads.
Our valve bodies, pipeline fittings, and forged steel unions are cast using LCC alloy steel and silica sol techniques. This ensures zero internal porosity, allowing them to perform reliably in high-pressure, low-temperature, and corrosive chemical settings.
Engineered to resist abrasion and impact, our custom agricultural machinery parts are designed to handle dust, moisture, and variable mechanical torque. These parts are finished with advanced anti-rust plating for long-term field durability.
International sourcing requires careful planning around shipping schedules, tariffs, trade compliance, and quality documentation. HAOCHU supports global procurement teams by providing comprehensive logistics documentation, complete material test reports (MTR), and localized customer support.
We work closely with global logistics networks to offer flexible delivery terms (FOB, CIF, DDP, DAP) directly from the Port of Ningbo, one of the world's most active shipping hubs. This ensures predictable delivery schedules and simplifies customs clearance.
Whether you require early-stage prototype evaluation (7-12 days) or a ramped-up schedule for wholesale production, we offer low MOQ flexibility, reliable inventory buffering, and quick turnarounds to support your operations.
