Explore our internationally certified, high-performance machinery designed to automate castings processing and surface finishing.
Xiamen DingZhu (DZ) Intelligent Equipment Co., Ltd. was founded in 2016. Since our inception, we have been principally engaged in the research, development, and manufacture of automatic equipment for the global foundry industry. Our engineered systems are widely deployed in the plumbing hardware, sanitary fittings, automotive spare parts, and industrial valves sectors.
We provide a comprehensive product suite that covers the entire casting production cycle: from automatic sand core shooting machines and gravity die casting machines to advanced double-head Low-Pressure Die Casting (LPDC) systems and fully integrated robotic cell grinding and polishing stations. We empower factories to shift from hazardous manual grinding to highly efficient, intelligent automated finishing.
In the contemporary landscape of high-precision metal manufacturing, surface finishing has transitioned from a labor-intensive operational bottleneck to a core competitive differentiator. Historically, manual grinding and polishing stood as one of the most volatile processes in manufacturing, characterized by high rejection rates, safety liabilities, and severe inconsistencies in surface roughness parameters (Ra, Rz).
At Xiamen DingZhu (DZ) Intelligent Equipment Co., Ltd., our China Factory 4.0 infrastructure addresses these operational inefficiencies. By leveraging vertical integration—ranging from initial raw casting design assistance to the commissioning of CNC automatic polishing machines and robotic workstations—we provide global industrial buyers with unmatched supply chain resilience. Our manufacturing ecosystem ensures stable lead times and raw material reliability, buffering clients from global volatility.
Traditional manual polishing exposes operators to toxic metallic dust, leading to severe health hazards such as pneumoconiosis. Additionally, tool-wear degradation, fatigue-induced pressure deviations, and complex geometry profiles result in high scrap rates. Automated robotic systems mitigate these issues through:
Modern components demand distinct chemical and physical surface treatments. Xiamen DingZhu’s intelligent polishing systems are engineered with adaptive material intelligence, designed to optimize surface finishing across critical metallurgical families:
Zinc alloys are lightweight and complex, commonly used in decorative hardware and locksets. The polishing of zinc castings requires absolute force control to prevent breaking the delicate, dense skin layer of the casting. Our systems employ micro-pneumatic active force compliance to deburr parting lines without compromising structural dimensions.
Widely utilized in automotive motor shells, communication filter cavities, and electronic computer casings, aluminum alloys are susceptible to thermal deformation during aggressive grinding. Our high-efficiency automatic polishers combine dynamic rotational speeds and continuous dust-cooling systems to eliminate thermal distress and maintain geometric tolerances.
Plumbing sanitary fixtures and industrial valves are dominated by brass casting. The finishing of heavy lead-free brass faucets requires robust torque and multi-axis coordination. DingZhu’s robotic systems are designed with heavy-load configurations, utilizing highly resilient abrasive belts and polishing wheels to achieve flawless surfaces prior to electroplating.

Direct visualization of our robotic solutions deployed in key industry segments.
The manufacturing landscape is evolving rapidly, driven by advanced computational control, artificial intelligence, and ecological compliance. The technology roadmap for Xiamen DingZhu's automated metal polishers is designed around these transformative trends:
Future iterations of robotic polishing systems will rely heavily on integrated 6-axis force-torque sensor arrays. Rather than executing a pre-programmed spatial path, the robot dynamically measures the contact resistance against the polishing wheel. If a casting variation is detected, the controller instantly adjusts tool positioning to maintain identical contact pressure, guaranteeing uniform metal removal rates and avoiding surface gouging.
Manual path programming for complex geometries remains highly complex. Our upcoming software architecture implements automated visual inspection. High-resolution 3D blue-light scanners capture the physical geometry of raw castings, mapping parting lines and casting flash. The control software automatically generates the optimized grinding and polishing path without human intervention, reducing changeover programming times from days to minutes.
Global environmental mandates necessitate a clean factory environment. We are integrating wet dust collectors with cyclonic separators directly into our enclosed robotic cells. Heavy metallic dust and abrasive waste are instantly precipitated into inert sludge, preventing atmospheric pollution and minimizing explosion hazards linked with lightweight aluminum and zinc residues.
Deploying heavy machinery internationally requires adherence to localized safety frameworks and rapid maintenance response mechanisms. Our global distribution network ensures that every exported system operates under rigorous safety guidelines, backed by engineers fluent in local compliance standards.
With localized service centers operational across major trade corridors—such as Egypt, Turkey, India, and Iran—we eliminate the friction of technical language barriers and customs clearance delays for replacement parts. Our localized support ensures that on-site engineers arrive within 24 hours of notification, minimizing downtime and ensuring smooth operational workflows.
Our commitment to rigorous design parameters and occupational safety is validated by global industrial certifications. Every machine exported meets CE specifications and ISO quality control structures, proving the reliability of our automated platforms.
Technical and procurement answers designed for manufacturing engineers and purchasing executives.
Our automatic metal polishing systems achieve a range of finishes depending on product specifications. Through progressive multi-station grinding using specialized abrasive belts and cotton wheels, our robotic cells can achieve a mirror finish with a surface roughness of Ra < 0.2μm, ideal for electroplating sanitary fittings and automotive hardware.
Our systems integrate pneumatic and electrical active compliance modules. By measuring surface resistance in real-time, the robot compensates for micro-dimensional variances in casting thicknesses. This maintains stable tool pressure, preventing over-grinding and safeguarding the delicate exterior layer of zinc and aluminum alloys.
Xiamen DingZhu has fully operational service hubs in India, Egypt, Turkey, and Iran. These facilities are staffed with specialized technicians and hold over 80% of standard wear items (such as contact wheels, pneumatic actuators, and pulleys). We commit to dispatching on-site support within 24 hours of notification, increasing maintenance speed by 60% compared to traditional importing schemes.
Yes. Our polishing workstations feature adaptive offline programming and rapid-changeover modular clamping systems. Switching between different product lines—such as door handles, brass faucets, and automotive components—requires only a simple tool plate replacement and loading the appropriate digital program, making it perfect for high-mix, low-volume production.
All automated cells handling aluminum and zinc alloys are equipped with localized explosion-proof wet dust collectors. The grinding chamber instantly extracts micro-dust and forces it into a water-spray filtration unit, safely precipitating the highly volatile dust particles as heavy sludge before they can reach dangerous concentrations in the air.
