Established in 2013, Ningbo Yinzhou Haochu Machinery Manufacturing Co., Ltd. has evolved from a specialized casting workshop into a premier Household Appliance Stamping Die Supplier. We integrate advanced forging and stamping technologies to serve the ultra-competitive global appliance market.
Our facility houses 40+ modern CNC lathes and high-precision machining centers. We specialize in stamping die design that ensures structural integrity for refrigerators, washing machines, and HVAC systems. With a technical team comprising 30% of our workforce, we guarantee 99.5% product qualification.
ISO 9001:2015 certified, we apply a three-tier inspection system. Our commitment to Information Gain means we don't just provide dies; we provide metallurgical consultancy and design optimization to reduce material waste by up to 15% for our clients.
Leading the shift from traditional tooling to Intelligent Stamping Systems.
As a leading Household Appliance Stamping Die Factory, we recognize that the future of appliance manufacturing lies in "Smart Tooling." Our roadmap involves integrating IoT sensors within the die blocks to monitor real-time pressure and temperature, preventing tool fatigue before failure occurs.
Micro-Precision Stamping: With the miniaturization of smart home electronics, our technical focus has shifted to micro-stamping capabilities, achieving tolerances within 0.02mm. This is essential for the high-density internal components of modern premium appliances.
Sustainable Tooling: We are pioneering the use of eco-friendly lubricants and vacuum heat treatments to extend die life cycles, aligning with global ESG (Environmental, Social, and Governance) goals. This ensures that our global partners receive the most "resilient" tooling solutions available in the China market.
Unlike standard suppliers, Haochu controls the entire value chain—from raw material sourcing and casting to final precision machining. This reduces lead times by 25% compared to outsourced competitors.
Our "7-12 Days Fast Proofing" protocol allows appliance manufacturers to iterate designs rapidly. We handle multi-size and multi-type sampling simultaneously, crucial for "Time-to-Market" strategies.
By leveraging Ningbo's world-class port logistics and a robust local supply network, we ensure zero-delay delivery, even during global supply chain fluctuations.
Heavy-duty progressive dies for washing machine drums and refrigerator panels requiring aesthetic surface finishes and structural durability.
High-thermal conductivity aluminum components and copper tube sheets, stamped with precision to ensure maximum energy efficiency in air conditioning units.
Cost-effective, high-speed stamping solutions for coffee machines, blenders, and smart home hubs, focused on high-volume production efficiency.
Navigating international standards is a core competency at Haochu. We ensure all Household Appliance Stamping Dies exported to Europe, North America, and Southeast Asia meet local safety and material regulations. Our technical team provides on-site installation guidance and virtual maintenance support to bridge the geographical gap.
We are fully compliant with RoHS and REACH standards, ensuring that no hazardous substances are used in the die manufacturing process. For our North American clients, we offer tooling documentation that simplifies customs clearance and ensures seamless integration into local production lines.
A: We typically use high-grade tool steels like D2, SKD11, and DC53, depending on the production volume and material being stamped (stainless steel, aluminum, or cold-rolled steel).
A: Yes, our factory is equipped for mass production. We design progressive dies capable of hundreds of thousands of cycles with minimal maintenance, optimized for high-speed stamping presses.
A: Our QC process includes CMM (Coordinate Measuring Machine) inspections of the die components and "First Article Inspection" (FAI) of the stamped parts before the die leaves our factory.
A: Absolutely. Over 80% of our business is custom OEM/ODM. We work directly from your CAD files (STEP, IGES, DWG) to create bespoke tooling solutions.
The company has a technical team and professional quality control personnel, ensuring product quality and consistent performance across all batches.
ISO 9001 certified, with a three-level inspection process, ensuring reliable product quality and adherence to international manufacturing standards.
The company has modern machining equipment and high-precision inspection instruments, meeting strict precision requirements of 0.02mm.
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.
