Foshan Dingyi: 0.01mm Precision Control + Full Traceability Redefining High-End Sheet Metal Standards

Published: April 13, 2025 | Category: Technology Insights | Source: Foshan Dingyi Industrial Technology

In the high-end equipment manufacturing sector, the precision stability and quality traceability of sheet metal components directly determine the operational reliability and troubleshooting efficiency of entire equipment systems. As industries such as photovoltaics, medical devices, and semiconductors continuously raise quality requirements for components, traditional processing models relying on manual experience can no longer meet the stringent demands of high-end fields. Foshan Dingyi Industrial Technology, through the dual empowerment of mechanical precision optimization and digital process upgrading, has established an industry-leading "micron-level precision control system" and "full-link digital traceability system", providing quantifiable, traceable, and reproducible high-quality sheet metal processing services for customers in high-end manufacturing sectors.

Mechanical-Grade Precision Control: Triple System of Equipment, Process, and Inspection Ensures Stable 0.01mm Precision Output

Foshan Dingyi Industrial Technology abandons the extensive model of "relying on experience and feeling" in traditional sheet metal processing, and constructs a three-layer precision control system based on "top-level equipment as foundation, standard process as framework, and precision inspection as guarantee", achieving stable mass production with 0.01mm processing precision.

1. Top-Tier Hardware Configuration: Guaranteeing Precision Upper Limit from the Source

The company has invested over 50 million RMB to introduce world-class processing equipment and establish high-precision processing units with the highest industry standards:

• Cutting Process: Equipped with Swiss Bystronic ByStar Fiber 6025 laser cutting machine, with positioning accuracy of ±0.003mm, repeat positioning accuracy of ±0.001mm, cut surface roughness Ra ≤ 1.6μm, no slag, no deformation, and cutting precision stably controlled within 0.01mm.

• Bending Process: Configured with Japanese Amada HG series CNC bending machines, equipped with grating scale closed-loop control system, bending angle accuracy ±0.1°, position accuracy ±0.01mm, enabling high-precision mass processing of complex multi-fold parts.

• Welding Process: Adopting German Carl Cloos welding robots, weld positioning accuracy ±0.05mm, welding deformation controlled within 0.1mm/㎡, solving the industry pain points of large deformation and poor consistency in traditional manual welding.

2. Standardized Process System: Achieving Stable and Repeatable Precision in Mass Production

For parts of different materials, thicknesses, and structures, Foshan Dingyi has established a standardized process database containing more than 1200 sets of process parameters, realizing automatic matching of processing parameters:

• According to the characteristics of different materials such as stainless steel, aluminum alloy, and galvanized sheet, pre-store optimal parameters including cutting power, feed speed, and bending pressure to avoid manual adjustment errors;

• Develop proprietary anti-deformation processes for high-precision parts, reducing processing deformation by more than 80% through combined measures such as segmented processing, stress relief, and tooling fixation;

• All process parameters have been verified through more than 1000 batches of production, with precision qualification rate stably above 99.8%.

3. Full-Dimension Inspection System: Preventing Non-Conforming Products from Leaving the Factory

Establish a three-level inspection system of "process self-inspection + patrol inspection + finished product final inspection", equipped with more than 30 sets of professional testing equipment to achieve full-dimensional precision control:

• Dimensional Inspection: Three-coordinate measuring machine (accuracy 0.001mm), 2D image measuring instrument, laser interferometer and other equipment cover full-size inspection requirements, with 100% full inspection of key dimensions;

• Appearance Inspection: Adopting machine vision inspection system, which can identify surface scratches, dents and other defects above 0.02mm, with appearance qualification rate reaching 99.5%;

• Performance Testing: Salt spray test chamber, vibration test bench, waterproof and dustproof test system and other equipment verify product reliability under extreme working conditions.

Full-Link Digital Traceability: ERP + MES System Integration Enables Full Life Cycle Traceability for Every Product

Foshan Dingyi Industrial Technology has invested 12 million RMB to build a digital workshop, and through the deep integration of ERP system and MES system, established a digital traceability system covering the entire life cycle from "raw material entry - production process - finished product delivery - after-sales service", realizing rapid positioning and closed-loop improvement of quality issues.

1. Raw Material Stage: 100% Traceability of Batch Information

All raw materials are bound with unique QR codes upon entry, recording the following information:

• Supplier information, material certificates, furnace batch numbers, and incoming inspection reports;

• Warehousing time, storage location, and collection records;

• Traceable to the production batch information of upstream steel mills, enabling reverse traceability of raw material quality issues.

2. Production Stage: Real-Time Collection of Process Data

Each production order generates a unique production process card, and full-process production data is collected in real time through workshop IoT devices:

• Operator, processing time, equipment number, and process parameters for each process;

• Inspection data, inspector, and qualification status for each process;

• Abnormal problem records, corrective measures, and verification results, realizing fully transparent management of the production process.

3. Finished Product Stage: Full-Dimension Information Association

Unique product identification codes are generated when finished products leave the factory, associated with the following information:

• Raw material batch information, full production process records, and factory inspection reports;

• Customer information, order number, delivery time, and logistics information;

• After-sales maintenance records, problem feedback, and improvement measures, realizing information closed-loop throughout the product life cycle.

Flexible Production Capacity: Balancing High Precision and High Efficiency to Meet Diverse Order Requirements

While ensuring high precision and traceability, Foshan Dingyi has established a production system that combines scale and flexibility through automated equipment configuration and flexible production layout:

• Large-Scale Production Capacity: 17,000㎡ standardized factory building, more than 200 sets of automated equipment, monthly production capacity covers 300+ sets of rack sheet metal, 1200+ sets of cabinets, and 100,000+ precision sheet metal parts, capable of undertaking stable delivery of million-level large orders;

• Urgent Order Response: Establish a 72-hour urgent order green channel, equipped with a dedicated rush order production team, supporting 24-hour shift operations, enabling sample order delivery in 48 hours and small-batch urgent order delivery in 72 hours;

• Flexible Production Capability: Through the digital scheduling system, it can simultaneously adapt to two modes: "small-batch multi-variety customization" and "large-scale standardized production", with production changeover time reduced by 60% compared to the industry average.
