Xiamen DingZhu Intelligent Equipment Co., Ltd. is a professional manufacturer of intelligent manufacturing equipment, specializing in robotic grinding and polishing systems, foundry equipment, and customized automation solutions.

With more than 25 years of industry experience, DingZhu integrates R&D, engineering, manufacturing, quality control, installation, commissioning, and after-sales service to provide complete production solutions for manufacturers worldwide.

Our equipment is widely used in sanitary ware, plumbing hardware, automotive components, valves, electronics, and general metal manufacturing, helping customers improve production efficiency, surface quality, workplace safety, and manufacturing consistency.

From a single automated polishing machine to a complete robotic finishing line, DingZhu provides solutions designed around the customer's product, production volume, factory layout, and finishing requirements.

Our robotic finishing systems are designed for complex metal components with curved, irregular, or difficult-to-process surfaces.

Using multi-axis industrial robots, adaptive force control, abrasive tools, rotary polishing systems, and customized fixtures, our solutions can automate processes that traditionally depend heavily on manual grinding and polishing.

Typical applications include:

• Stainless steel faucets

• Brass sanitary ware

• Shower components

• Valves and plumbing hardware

• Door handles

• Automotive components

• Aluminum alloy wheel hubs

• Zinc alloy components

• General metal castings

The system can be configured for grinding, deburring, surface preparation, polishing, buffing, and other finishing operations.

DingZhu automatic polishing machines are developed for manufacturers looking to increase production capacity while maintaining consistent surface quality.

Depending on the product and process requirements, automatic polishing systems can reduce manual operations, improve process stability, and create a more consistent surface finish across production batches.

They are suitable for products including sanitary ware, plumbing hardware, metal fittings, and other mass-produced components.

Our low pressure die casting machines are designed for efficient and stable production of high-quality metal castings.

The equipment can be configured with advanced hydraulic and control systems to improve production stability, energy efficiency, and operational reliability.

Typical applications include:

• Faucets and sanitary ware

• Automotive components

• Aluminum alloy components

• Hardware castings

• Other precision metal castings

The system can also be integrated with automated handling and downstream finishing equipment to create a more complete production process.

DingZhu gravity die casting machines provide a practical solution for manufacturers producing aluminum, brass, and other non-ferrous metal castings.

The equipment can be customized according to casting size, mold structure, production requirements, and automation level.

For customers seeking higher production efficiency, casting equipment can also be combined with automated material handling, trimming, grinding, and polishing processes.

Our automatic sand core shooting machines are designed to improve the efficiency and consistency of core-making operations.

Automation helps manufacturers achieve more stable core production while reducing dependence on manual operations.

The equipment can be configured according to core size, mold structure, production capacity, and customer-specific process requirements.

Our automatic CNC sprue cutting solutions are designed to remove casting sprues and excess material with improved consistency and repeatability.

By integrating automated positioning, CNC machining, and customized fixtures, the system can reduce manual trimming operations and improve production efficiency.

The solution is suitable for applications in sanitary ware, automotive components, hardware, and other casting industries.

Automated grinding and polishing solutions for faucets, showerheads, valves, bathroom accessories, and other sanitary hardware.

Our robotic systems are particularly suitable for products with complex curves and multiple surface geometries where manual finishing can be difficult to standardize.

Robotic grinding and polishing systems can be configured for aluminum alloy wheels, cast automotive components, exhaust components, and other metal parts requiring consistent surface finishing.

Multi-axis finishing systems can be adapted for aluminum, zinc alloy, and other metal housings and components requiring precise surface treatment and high-quality cosmetic finishes.

Automation solutions are available for deburring, grinding, polishing, and surface preparation of valves, fittings, handles, and other industrial metal components.

Designed for high-volume sanitary ware production, this robotic polishing solution can process complex stainless steel faucet geometries while maintaining consistent finishing quality.

Typical solution highlights:

• High-speed automated polishing

• Multi-axis robotic movement

• Customized fixtures and abrasive tools

• Consistent surface finishing

• Reduced dependence on manual polishing

• Integration with existing production processes

For specific faucet models and production requirements, the system can be engineered and tested before delivery.

Our six-axis robotic grinding systems can be equipped with adaptive force control to maintain stable contact between the abrasive tool and the workpiece.

In a customer application involving aluminum alloy wheel hubs, the finishing process achieved a target surface roughness of Ra ≤ 0.4 μm, while rework requirements were significantly reduced.

Actual results depend on the workpiece material, geometry, abrasive system, process parameters, and required surface finish.

For zinc alloy components such as electronic housings and consumer-product casings, DingZhu can develop multi-axis polishing solutions for high-quality cosmetic finishing.

A customized system can combine:

• Robotic handling

• Multi-axis polishing

• Customized abrasive tools

• Offline programming

• Automatic process control

• Precision fixtures

For suitable applications, the system can be configured to achieve mirror-like surface finishes with target roughness levels as low as Ra ≤ 0.15 μm.

Not every manufacturer has a large factory floor.

DingZhu therefore offers compact robotic finishing cells designed for workshops with limited available space.

The modular structure allows key components such as the robot, grinding system, polishing unit, fixtures, dust collection system, and control cabinet to be integrated into a compact production cell.

• Compact footprint

• Modular design

• Easier installation

• Flexible production configuration

• Future upgrade potential

• Reduced manual finishing operations

For certain customer applications, energy consumption can also be reduced compared with conventional equipment, depending on the production process and machine configuration.

Grinding and polishing processes generate metal dust and abrasive particles. A properly designed finishing cell therefore needs to consider both production efficiency and the working environment.

DingZhu can provide enclosed robotic grinding cells equipped with dust extraction and filtration systems.

Depending on the application, the system can include:

• Fully enclosed grinding area

• Industrial dust extraction

• HEPA filtration

• Real-time emission monitoring

• Safety interlocks

• Automated process control

The final configuration is designed according to the customer's local safety, environmental, and workplace requirements.

Automation is not simply about installing a robot.

A successful robotic finishing project requires the entire process to be engineered around the actual product.

At DingZhu, our engineering process typically includes:

Every factory has different products, production volumes, labor conditions, and space limitations.

That is why DingZhu does not rely on a one-size-fits-all approach.

Our engineering team can customize:

• Robot configuration

• Grinding and polishing tools

• Abrasive systems

• Workholding fixtures

• Rotary positioning systems

• Automatic loading and unloading

• Dust extraction

• Safety enclosures

• PLC and HMI systems

• Production line integration

• Offline programming

• Inspection and quality control systems

Whether you are automating one production process or building a complete automated finishing line, our engineers can develop a solution based on your actual requirements.

Over the years, DingZhu has worked with customers and industrial groups across sanitary ware, automotive, hardware, and other manufacturing sectors.
