About This Case
Renowned mold manufacturer Taiwan Sekiguchi Industry Co., Ltd. deployed the MiDFUN SPC Statistical Process Control system, and through a customized file-conversion program and the QIR Intelligent Reporting module, successfully consolidated quality data scattered across many locations onto a single platform. After deployment, quality control staff no longer need to manually copy and paste to produce COA reports; they now achieve one-click export of customized reports while automatically generating the monthly reports, quarterly reports, and Cpk analysis charts that management requires.
Customer Profile: Taiwan Sekiguchi Industry Co., Ltd.
Taiwan Sekiguchi Industry Co., Ltd. is a well-known domestic precision mold manufacturer specializing in the design and production of high-precision molds. Molds have long been hailed as the “mother of industry,” and their quality directly affects the precision and reliability of downstream products. Facing customers’ ever-increasing demands for transparency in quality data, Taiwan Sekiguchi Industry actively sought a digital solution to improve quality management efficiency and strengthen customer trust.
Project Background: Scattered Data Like a Complex COA Jigsaw Puzzle
Before deploying the MiDFUN SPC system, the biggest challenge Taiwan Sekiguchi Industry faced was “data integration.” Inspection data within the plant was stored separately across various Excel files and computers, creating a classic case of data silos.
Whenever a shipment required producing a COA (Certificate of Analysis) to provide to the customer, quality control staff had to open multiple files, manually locate the corresponding lot-number data, and then copy and paste it into the report one entry at a time. This “piecing-it-together” way of working not only consumed a great deal of labor hours but also concealed the risk of human key-in errors.
Even more serious, because the data was not systematically centralized, conducting long-term quality trend analysis or process capability studies often required days of data preparation, and was sometimes difficult to carry out at all. Managers could not grasp the full picture of product quality in real time, and decisions could only rely on experience rather than data.
Three Major Pain Points Before Deployment
Data silos: Inspection data was scattered across different Excel files and computers, with no unified management platform.
Time-consuming report production: COA reports required manual copy and paste — a tedious, error-prone process.
Limited analytical capability: Long-term trend analysis required days of data preparation, and management decisions lacked real-time data support.
Why Choose the MiDFUN SPC System
Customized File-Conversion Program: Building an Automated Data Workflow
To resolve the difficulties faced by frontline staff, the MiDFUN team conducted in-depth interviews with Taiwan Sekiguchi Industry’s IT and quality assurance units, and ultimately adopted a more flexible approach — developing a “customized Excel file-conversion program.”
With this solution, Taiwan Sekiguchi Industry only needs to place the data files generated by inspection instruments into a designated folder on the computer, and the MiDFUN SPC system automatically detects them, converts the format, and imports them. This change delivered immediate results, dramatically reducing the time staff spent manually keying in data and allowing quality control personnel to return to their professional analytical work.
One-Click COA Export: Goodbye to Copy-Paste Hell
The MiDFUN SPC system integrates the report formats specified by each customer. Now, staff simply select the template for whichever customer the shipment is going to, and the system can generate a polished COA report with one click via the “custom format export” function. Quality control personnel have completely left behind the tedious copy-paste work of the past, investing their time instead in more valuable quality improvement analysis.
QIR Intelligent Reporting Module: Automating Management Reports
Beyond the everyday shipping reports, in 2025 Taiwan Sekiguchi Industry’s internal user units further raised a requirement to optimize management reports. In the past, the monthly and quarterly reports needed by production unit managers and quality review meetings were often the month-end nightmare of the quality control department.
After deploying MiDFUN SPC’s “QIR Intelligent Reporting Management module,” the system can regularly and automatically organize data and plot analysis charts according to preset conditions (such as a specific time range), including defect-rate trend charts, Pareto charts, Cpk analysis, and more. More importantly, the system automatically sends these reports by email to designated managers for review, ensuring that the management team receives accurate, real-time quality decision-making evidence.

| COA custom format export | Generates a Certificate of Analysis with one click based on the customer template | Significantly improved report production efficiency |
| QIR Intelligent Reporting module | Automatically generates management reports and sends them by email | Real-time management decision-making |
| Cpk process capability analysis | Automatically calculates and tracks process capability indices | Quality trends seen at a glance |
Conclusion: The Transformation Journey from Data Silos to Intelligent Quality Control
The Taiwan Sekiguchi Industry case fully demonstrates the strength of the MiDFUN SPC system in solving the quality-data management pain points of the manufacturing industry. Through a customized solution, it not only resolved the daily difficulties of frontline staff but also provided management with real-time, accurate decision-making evidence.
This not only addresses the manufacturing industry’s widespread labor shortage but also ensures that management receives accurate quality decision-making evidence in real time, truly delivering quality management that is both immediate and efficient. For the mold manufacturing industry, which pursues the utmost precision, quality data is not merely an inspection result but a commitment to the customer — and the MiDFUN SPC system is the best partner for fulfilling that commitment.

Frequently Asked Questions (FAQ)
Q1: What is the SPC Statistical Process Control system?
SPC (Statistical Process Control) is a management method that uses statistical techniques to monitor the stability of a production process. Put simply, just as you might weigh yourself daily to track your health, the SPC system continuously collects inspection data, automatically plots control charts, and calculates process capability indices such as Cpk, allowing quality control staff to detect anomalies in real time and take corrective action. The MiDFUN SPC system goes a step further by integrating functions such as automatic file conversion and report export, helping the manufacturing industry achieve quality management automation.
Q2: What concrete results did Taiwan Sekiguchi Industry gain after deploying the MiDFUN SPC system?
Taiwan Sekiguchi Industry gained three major results after deployment: first, the customized file-conversion program eliminated the repetitive work of manually keying in data; second, COA reports went from copy-and-paste to one-click export; third, management reports are automatically generated and sent via the QIR module, allowing managers to grasp quality decision-making evidence in real time.
Q3: Can the MiDFUN SPC system integrate with existing inspection instruments?
Yes. The MiDFUN team conducts in-depth interviews to understand the customer’s existing instruments and data formats, then develops a customized file-conversion program. In the case of Taiwan Sekiguchi Industry, staff simply place the data files generated by the instruments into a designated folder, and the system automatically detects, converts, and imports them — with no need to replace existing equipment.
Q4: How long does it usually take to deploy the MiDFUN SPC system?
The deployment timeline varies with customer requirements and complexity. Generally, deploying standard functions takes about 2-3 months; if it involves a customized file-conversion program or integration with other systems, it may take 4-6 months. MiDFUN conducts a thorough requirements interview at the start of the project and provides a clear deployment schedule.
