Precision plastic quality, digital intelligence casting the future: Dongguan Jingmu Mold Plastic Products Co., Ltd. drives excellent mold manufacturing with precise measurement
In the increasingly competitive field of precision manufacturing, quality is the lifeline of enterprises, and precision is the soul of quality. Dongguan Jingmu Mold Plastic Products Co., Ltd. has been well versed in this field since its establishment in 2003, engraving the word "precision" into the gene of enterprise development. The company is located in Changping Town, Dongguan City, with convenient transportation. It has over 2500 square meters of modern factory buildings and nearly 120 experienced professional teams, committed to providing global customers with one-stop precision mold solutions from design, manufacturing to injection molding. It is particularly worth mentioning that the crystal wood mold always adheres to a core principle throughout the entire processing process: all workpieces must undergo strict measurement and be 100% compared with the original 3D model to confirm accuracy before proceeding to the next process. This seemingly simple persistence is the cornerstone of the company's effective control of accumulated errors, ensuring that the final product perfectly matches the design intent, and thus winning the trust of well-known brands such as Ford, Haier, OPPO in the market.
1、 Build an accuracy defense line based on measurement
In mold manufacturing, errors are like shadows that accompany every processing step. Minor deviations in a single process, if not corrected, will be continuously transmitted and amplified in subsequent processes, forming irreparable cumulative errors, ultimately leading to mold scrap or product failure. Jingmu Mold deeply realizes that in order to break this "error chain", precise "checkpoints" must be set up at every key node.
To this end, the company has fully introduced a high-precision detection system based on coordinate measuring machines (CMM). For each completed workpiece, whether it is the core mold core, slider, precision guide column, or ejector pin, the inspection personnel will conduct systematic inspection on the coordinate measuring instrument based on the 3D digital model (digital model) and 2D drawings provided by the customer. This process is far from a simple size check, but a rigorous scientific process: first, a detailed analysis of the workpiece is conducted to clarify the benchmark and measurement requirements; Subsequently, select a suitable diameter (such as Φ 2mm to Φ 4mm) and angle ruby measuring needle for calibration; Next, by measuring benchmark features on the physical object (such as planes, circles, and lines) and iteratively fitting them with theoretical values in the numerical model, a high-precision coordinate system is established to ensure that the spatial position of the virtual model completely coincides with that of the physical object. Finally, precise measurements of points, lines, surfaces, and circles are carried out for the key positions marked on the drawings or numerical models.
The measurement data will generate detailed detection reports in real-time. In the report, the deviation between the actual value and the theoretical value of each measurement point is presented in the form of a visual chromatogram or data table. Green represents qualified, while yellow or red indicates a warning of exceeding the tolerance. Only when all testing items meet the strict tolerance requirements, will the workpiece be released and enter the next stage such as precision machining, discharge, or assembly. This closed-loop process of "measurement comparison decision" is like installing a pair of "smart eyes" for the production process, containing errors in their infancy and ensuring consistency in error transmission between processes. Even if there are inherent errors in the equipment during the processing, they are controlled in a known, controllable, and consistent direction and magnitude through timely measurement feedback and correction, avoiding the accumulation and outbreak of random errors.
2、 Systematic support, making precision a habit
Accurate measurement practice cannot be separated from a strong technical system and strict management system as a backing. The precision of crystal wood molds is reflected in the following three aspects:
Firstly, there is a continuous investment in software and hardware technology. The company's engineering design and development department has 10 senior engineers who fully adopt internationally leading CAD/CAM/CAE computer-aided technology for product design and simulation analysis, ensuring the rationality and manufacturability of the design from the source. In the testing process, not only is a high-precision three coordinate measuring machine equipped with the Haixkang universal type, but more advanced digital measurement technology is also actively explored. For example, for large automotive molds with complex surfaces or workpieces that require analysis of overall deformation, the company has introduced 3D scanning technology. This technology can quickly obtain full-size 3D point cloud data without touching the surface of the workpiece, and compare it with the original CAD model to generate a global deviation chromatogram. It is particularly skilled in discovering surface deviations and assembly interference problems that are difficult to reach with traditional contact measurements, providing irrefutable data basis for virtual assembly and mold modification.
Secondly, there is a standardized operating procedure (SOP) that runs throughout the entire process. The company has obtained ISO9001 quality management system certification and established a complete "Mold Production Process Operation Specification" and "Mold Work Management System". These systems clarify the responsibilities and standards for the entire process from mold drawing review, processing and manufacturing, first article inspection to final factory delivery. The Technical Sales Department is responsible for reviewing the mold structure and tracking trial mold issues, the Production Technology Department is responsible for developing detailed operation manuals and process materials, and the Quality Department is dedicated to establishing inspection standards and supervising the quality of the production process. Each operation has rules to follow and evidence to rely on, making "measuring and comparing 3D" not a temporary requirement for a certain link, but a mandatory step embedded in the daily work instructions of each employee.
Thirdly, it is the profound accumulation of talents and experience. Mold manufacturing is an industry that highly integrates experience and technology. Jingmu Mold has a group of design and development personnel with rich mold making experience and high-quality mold manufacturing elites. They are not only proficient in equipment operation, but also have a deep understanding of material properties and process principles. When abnormal measurement data occurs, they can quickly determine whether it is caused by machine tool errors, tool wear, or stress deformation based on experience, and develop the most effective compensation or correction plan. This ability to combine quantitative data with expert experience makes error compensation more accurate and efficient. In fact, academic research also supports this model, which obtains deviation information through online measurement and adjusts CNC machining programs in real time based on it, which is an effective technical approach to improve the machining quality of complex curved parts.
3、 Accurate value, empowering customers to succeed
The paranoid pursuit of "zero error" has brought tangible value to Jingmu Mold and its customers:
Reliable quality and on-time delivery: Through layers of quality control in the manufacturing process, the number of mold trials and subsequent modifications and rework have been significantly reduced, ensuring the stability of mold delivery time and the consistency of the final injection molded product quality.
Cost optimization and strong competitiveness: Identify and correct problems in advance, avoiding huge losses caused by mold scrap or mass production of defective products. The ability to do things right the first time constitutes the core competitiveness of the company in serving domestic and international markets, and exporting its products to the United States, Japan, Europe, and other places.
The cornerstone of trust, win-win cooperation: rigorous data reporting and stable quality output have become the most powerful language for communicating with customers. Whether providing automotive parts molds for Ford and Renault, or developing electronic consumer product molds for Skyworth and HP, Jingmu Mold has established a solid trust bond with accurate data.
Looking ahead to the future, with the deepening development of Industry 4.0 and intelligent manufacturing, Jingmu molds will continue to deepen the application of digitization and intelligence in precision control. We plan to further integrate measurement data into the Manufacturing Execution System (MES) to achieve predictive compensation for machining errors and full lifecycle quality traceability, pushing "precision manufacturing" to a new height of "intelligent precision manufacturing".
Skilled in craftsmanship, skilled in heart, skilled in action. Dongguan Jingmu Mold Plastic Products Co., Ltd. will continue to use 3D digital modeling as the blueprint, precision measurement as the cutting edge, continuously carve every set of molds, safeguard every commitment, and work together with global partners to shape a more precise and reliable industrial future.
