First, locating materials takes a long time, cutting into productive working hours. Traditional storage methods involve placing various mold components on open shelving, where material labels are prone to oil stains, wear, and blurred lettering. When operators retrieve mold inserts or inspection gauges, they must manually search through a large number of storage locations, with each search taking an average of 15 to 30 minutes. In situations involving urgent mold trials or emergency repairs, delays in locating materials can easily lead to production line downtime and project delays. Industry data shows that in traditional mold workshops, the proportion of non-productive hours spent by operators searching for materials can reach 18% or more, continuously suppressing the effective utilization rates of machine tools and mold testing equipment.<\/p>\n\n\n\n
Second, the loss and misappropriation of high-value mold components are prevalent, making cost control difficult. Precision mold cores, custom inserts, and imported measuring tools have high unit prices, yet there is a lack of dedicated storage areas and issuance records. Under an open storage system with no access restrictions, mold components from different projects are easily mixed together or mistakenly taken; Some materials are not returned promptly after being issued and remain scattered across workstations for extended periods, resulting in hidden asset loss. Additionally, functional mold components are stored alongside those awaiting repair, and defective inserts are reused in assembly, leading to dimensional defects in trial-molded products and posing batch-wide quality risks.<\/p>\n\n\n\n
Third, inventory counting is inefficient, and there are persistent discrepancies between book and actual inventory levels. The mold shop typically handles over a thousand SKUs; relying on manual monthly inventory counts requires multiple managers to halt their work to verify the inventory, with the entire counting cycle taking as long as 2 to 3 days. Manual counting is highly prone to omissions and errors, with inventory discrepancy rates generally exceeding 3%. Since system inventory data cannot be updated in real time, managers find it difficult to accurately track remaining stock levels of mold components. This frequently results in shortages of urgently needed materials and long-term stockpiling of rarely used parts. As a result, procurement planning must rely on experience-based judgment, leading to a continuous increase in tied-up capital.<\/p>\n\n\n\n
Fourth, there is a lack of a complete traceability chain, resulting in inadequate maintenance management. Precision molds and inserts have a fixed service life and require regular maintenance. Traditional ledger records are fragmented, making it impossible to fully track the person who issued each set of mold components, the project for which they were used, the duration of machine operation, and their return status. When molds exhibit wear or precision deviations, it is difficult to quickly identify the specific usage scenario; furthermore, the system cannot automatically remind users of maintenance cycles, resulting in a large number of molds operating beyond their recommended service life, which shortens their lifespan and increases repair costs. During audits by high-end clients (such as those based on the IATF 16949 quality management system), the inability to provide complete material flow records negatively impacts the outcome of client factory inspections.<\/p>\n\n\n\n
Fifth, the warehouse layout is inefficient, resulting in a significant waste of space. Traditional heavy-duty racking requires a large amount of space to be reserved for pedestrian aisles, resulting in low space utilization. Mold components are stored in a scattered manner between the central warehouse and individual workstations, making the material transfer process cumbersome. Since the central warehouse is located far from the assembly and mold testing stations, operators spend a significant amount of time traveling back and forth to retrieve materials, making it difficult to achieve lean, line-side material supply.<\/p>\n\n\n\n
II. Technical Architecture and Operating Principles of Smart Storage Cabinets and the Smart Material Management System<\/h2>\n\n\n\n
The Smart Material Cabinet is an IoT-enabled smart hardware device designed for the management of high-value materials in manufacturing workshops. When paired with the\u914d\u5957 smart material management system, it forms an integrated \u201chardware sensing + software control\u201d solution that is widely applicable to the storage and management of molds, tooling, measuring instruments, and precision inserts. The entire system is divided into four major modules: the perception layer, the transmission layer, the application layer, and the data analysis layer. It can seamlessly integrate with MES (Manufacturing Execution Systems), ERP (Enterprise Resource Planning), and mold project management systems, thereby breaking down data silos on the shop floor.<\/p>\n\n\n\n
At the hardware level, the smart material cabinet features a modular design with independent compartments, each equipped with an electronically controlled lock, an RFID reader\/writer module, and status sensors. The unit is equipped with a touchscreen display and a card\/facial recognition terminal, supporting multi-factor authentication. The cabinet features a sealed, dust-proof structure and can be optionally equipped with a temperature-controlled dehumidification module to prevent precision mold components from becoming damp and rusting or developing surface oxidation spots, thereby safeguarding mold machining accuracy. The cabinet can be flexibly deployed in mold assembly areas, trial mold workshops, and alongside CNC lines to enable on-site material storage.<\/p>\n\n\n\n
At the software level, the Intelligent Material Management System serves as a digital control and management platform, handling functions such as material record management, permission assignment, control of issuance processes, real-time inventory updates, maintenance alerts, and data reporting and analysis. The system supports customizable material parameters, allowing users to enter information such as mold numbers, applicable projects, specifications and materials, maintenance cycles, and safety stock thresholds.<\/p>\n\n\n\n
The entire solution features clear operational logic: When mold components are received into inventory, a unique RFID tag is attached to each item, which is then entered into the system\u2019s database and stored in a dedicated compartment within a smart material cabinet; operators verify their identity via card swipe or facial recognition, and the system grants access to available compartments based on their job role permissions; After the material is retrieved, the system automatically records the person who retrieved it, the time, and the corresponding mold project; when the material is returned, the system automatically verifies its condition and updates inventory levels in real time; the system monitors inventory levels and maintenance due dates in real time, automatically sending alerts for material shortages and maintenance reminders. The entire process requires no paper documents, and all operations are automatically logged, enabling unmanned, self-service operations.<\/p>\n\n\n\n
Compared to automated warehouses and heavy-duty automated storage equipment, smart material lockers offer advantages such as low upfront costs, flexible deployment, no need for large-scale infrastructure upgrades, and a short deployment cycle. They are suitable not only for large-scale deployment in large mold factories but also for streamlined digital upgrades in small and medium-sized mold enterprises.<\/p>\n\n\n\n
III. Case Study: Details on the Implementation of Smart Material Cabinets at a Precision Electronic Mold Manufacturer<\/h2>\n\n\n\n3.1 Company Overview<\/h3>\n\n\n\n
The case study company is located in the Yangtze River Delta and specializes in the R&D and manufacturing of connectors for consumer electronics and precision injection molds for plastic housings. It currently has more than 420 sets of molds in production, along with over 2,600 SKUs of mold inserts, tooling fixtures, and precision measuring tools. All workshop materials were previously stored on traditional open shelving, leading to long-standing issues such as lost inserts, difficult inventory counts, low material issuance efficiency, and the haphazard mixing of mold components. As orders continued to grow, the manual management model struggled to support production capacity expansion. In late 2025, the company launched a digital transformation of its production workshop, introducing eight modular smart material cabinets and a corresponding smart material management system. These are used for the centralized management of mold inserts, precision measuring tools, and mold repair fixtures, establishing a smart material management system at the production line.<\/p>\n\n\n\n
3.2 Preliminary Research and Planning<\/h3>\n\n\n\n
In the early stages of project implementation, the project team completed a classification and organization of workshop materials: high-risk items such as high-value mold cores, custom inserts, and coordinate measuring machines were incorporated into the smart material cabinets for unified management; frequently used materials were distinguished from infrequently used components, and storage space allocation was optimized. Taking the workshop layout into account, the smart material cabinets were deployed in the mold assembly workshop and around the mold testing stations to create smart storage points right next to the production line, thereby reducing the distance personnel had to travel to and from the warehouse.<\/p>\n\n\n\n
At the same time, we completed the debugging of system interfaces, integrating the intelligent material management system with the company\u2019s existing MES mold project system. This enables synchronization between mold production work orders and material issuance, supports the aggregation of material consumption data by project, and allows for precise calculation of the manufacturing cost per mold set. Tiered access permissions were established for different roles: mold engineers, assembly fitters, and maintenance personnel were assigned differentiated material withdrawal permissions; time limits were set for the withdrawal of high-value tools, and warning notifications were automatically sent when items were not returned by the deadline.<\/p>\n\n\n\n
3.3 Implementation Process<\/h3>\n\n\n\n
Phase 1: Material Record Creation and Tag Assignment. Digital records were created for each of the more than 2,600 mold components subject to control, including information such as part number, applicable mold number, maintenance cycle, and procurement cost. RFID tags were attached to each component to establish a one-to-one correspondence between the materials and their storage locations.<\/p>\n\n\n\n
Phase 2: Hardware Installation, Commissioning, and Staff Training. Complete the network deployment of the smart material lockers, commission the lock control system, and test the identity recognition functions; organize operational training for workshop operators and warehouse managers; and clarify the standardized procedures for item retrieval, return, and reporting of anomalies.<\/p>\n\n\n\n
Phase 3: Trial Operation and Process Optimization. The new and old management models will operate in parallel for 30 days, during which time we will continuously optimize the system\u2019s alert rules and permission settings, collect feedback from the workshop, adjust the warehouse layout, and resolve practical issues encountered during material storage and retrieval.<\/p>\n\n\n\n
Phase 4: Full Transition and Routine Operations. Paper material requisition forms are eliminated, and the self-service smart material locker system is officially implemented. The system automatically generates daily material issuance reports, and managers use the backend to monitor inventory, issue maintenance reminders, and conduct cost analysis.<\/p>\n\n\n\n
3.4 Comparison of Key Metrics Before and After the Renovation<\/h3>\n\n\n\n
After 12 months of stable system operation, the company conducted a data review and found significant improvements in all operational metrics:<\/p>\n\n\n\n
- \n
- The average time to locate a material was reduced from 22 minutes to 1.5 minutes, and material issuance efficiency improved by 93%;<\/li>\n\n\n\n
- Incidents caused by lost or misclaimed mold components decreased by 87%, and the loss rate for high-value materials fell from 5.7% to 0.6%;<\/li>\n\n\n\n
- The inventory count for all product categories, which previously took 3 people 2 days to complete, has been replaced by an automated, real-time system, reducing the man-hours required for inventory counting by 90%;<\/li>\n\n\n\n
- Inventory data accuracy improved from 76% to 99.8%, effectively preventing production downtime due to material shortages and duplicate purchases;<\/li>\n\n\n\n

- A comprehensive digital traceability record easily meets the quality system audit requirements of downstream customers, with a 100% factory audit pass rate.<\/li>\n<\/ol>\n\n\n\n
From an economic perspective, reduced material waste, minimized downtime, and streamlined labor result in overall cost savings. The payback period for the complete smart material cabinet solution is 22 months, offering a favorable return on investment.<\/p>\n\n\n\n
IV. The Core Application Value of Smart Storage Cabinets in Precision Mold Management<\/h2>\n\n\n\n
Drawing on practical implementation experience, the combination of smart material lockers and the smart material management system delivers five core benefits tailored to the precision mold industry, addressing long-standing management challenges in the sector.<\/p>\n\n\n\n
First, it enables self-service, on-site material retrieval, thereby improving workshop operational efficiency. The smart material cabinets support 24-hour, unattended self-service material retrieval and are deployed in line-side areas, eliminating the need for operators to travel back and forth to the central warehouse. The system automatically locates material storage locations, and lighting guides operators to quickly retrieve materials, eliminating a significant amount of unnecessary walking and search time. This improves the continuity of mold assembly and trial runs, thereby increasing equipment utilization rates. New employees can operate the material retrieval system independently after minimal training, reducing reliance on the experience of senior workers and alleviating management pressures caused by staff turnover.<\/p>\n\n\n\n
Second, tiered access controls help prevent the loss of high-value mold assets. A dual-control system\u2014comprising a dedicated, electronically locked storage area and identity verification\u2014physically prevents unauthorized access. Every material transfer is linked to the operator and the corresponding mold project, creating a complete chain of accountability. The system supports the configuration of return deadlines and trade-in rules to prevent mold inserts and measuring tools from being occupied for extended periods without return. This effectively plugs loopholes that lead to asset loss and controls procurement costs for mold components.<\/p>\n\n\n\n
Third, real-time digital inventory management optimizes procurement and inventory structure. The intelligent material management system synchronizes material inbound and outbound data in real time and provides a visual representation of inventory status. Companies can customize safety stock thresholds; when material levels fall below these thresholds, replenishment alerts are automatically triggered, preventing mold project delays caused by urgent material shortages. Leveraging big data on material usage accumulated over time, managers can analyze the consumption rates of different types of mold components, optimize purchase batch sizes, reduce tied-up capital, and achieve lean inventory management.<\/p>\n\n\n\n
Fourth, full lifecycle traceability of molds ensures machining accuracy and quality compliance. The system comprehensively records data throughout the entire process\u2014from the receipt, issuance, machine setup, return, maintenance, and repair of mold inserts and measuring tools. When accuracy issues arise during mold trial runs, managers can quickly retrieve material usage records to pinpoint the root cause of the problem. At the same time, the system sends scheduled maintenance alerts to prevent precision mold components from operating beyond their service life, thereby stabilizing product processing yield rates. The comprehensive electronic ledger meets the audit requirements of quality management systems such as IATF 16949 and ISO 9001, enhancing the company\u2019s level of standardized management.<\/p>\n\n\n\n
Fifth, the lightweight digital transformation is suitable for mold manufacturers of all sizes. Compared to capital-intensive solutions such as automated high-bay warehouses, smart material cabinets do not require extensive facility renovations; they can be procured in phases and scaled up gradually. Small and medium-sized enterprises can start by managing their highest-value mold components and then continue to expand the scope of their management over time. The modular design of both hardware and software allows for future integration with AGVs, light-guided picking systems, and smart weighing racks, enabling a smooth transition to a complete smart warehousing system with exceptional scalability.<\/p>\n\n\n\n
V. Key Considerations for Implementation and Industry Outlook<\/h2>\n\n\n\n
For mold manufacturers deploying a smart material cabinet system to achieve the desired results, it is not enough to simply purchase hardware; they must focus on three key implementation points. First, develop a comprehensive material classification plan in the early stages, prioritizing the inclusion of high-value, high-turnover, and easily lost mold inserts and measuring tools within the control scope to avoid wasting resources by managing too many items; Second, prioritize system integration by connecting the interfaces of MES, ERP, and mold management software to enable data interoperability and prevent the creation of new data silos; finally, establish standardized workshop management systems to regulate the processes for material issuance, return, and exception handling. By ensuring synergy between hardware, software, and management processes, companies can maximize the value of their digital equipment.<\/p>\n\n\n\n
Competition in the precision mold industry continues to intensify, and product delivery cycles are constantly shrinking. Cost reduction, efficiency improvement, quality control, and digital capabilities have become core competitive advantages for mold manufacturers. Traditional manual warehousing models struggle to meet the demands of flexible production, making smart, line-side material management a key breakthrough for the digital transformation of mold workshops. Thanks to their flexible deployment, cost-effectiveness, and closed-loop traceability, smart material cabinets are rapidly gaining widespread adoption as a smart warehousing solution in mold factories.<\/p>\n\n\n\n
In the future, smart material cabinets will continue to integrate AI data analysis and IoT sensing technologies, combining them with mold production scheduling to predict material demand and dispatch materials to production lines in advance; at the same time, they will link with wear monitoring equipment to enable intelligent prediction of the service life of mold components. As hardware and software continue to evolve, smart material cabinets will no longer be merely storage devices but will become critical data collection nodes within the intelligent mold manufacturing system. They will drive the transformation of warehouse management in the mold industry from experience-driven to data-driven, helping precision mold manufacturers achieve lean production and high-quality digital transformation and upgrading.<\/p>","protected":false},"excerpt":{"rendered":"
