Dongguan Jingmu Mold: Revolutionizing Smart Manufacturing Standards for 3C Products Through Precision Mold InnovationAs a pioneering leader in high-end mold manufacturing within the Guangdong-Hong Kong-Macao Greater Bay Area, Dongguan Jingmu Mold Co., Ltd. (hereinafter referred to as "Jingmu Mold") has built deep-rooted expertise in precision mold manufacturing, specializing in the R&D and production of automotive connector molds, 3C electronic consumer product molds, and precision connector molds. By spearheading technological innovation, the company addresses industry challenges head-on, driving the evolution of domestic precision manufacturing toward smart, high-end, and refined technical standards.
Structural Innovation in 3C Product Design: Four-Slide Combination Design and Process OptimizationTo address the high-density, miniaturization demands of 3C electronic products, Jingmu Mold employs a four-slide combination design with multi-directional core-pulling mechanisms, enabling single-shot molding of complex cavity structures. This approach significantly enhances mold structural rigidity and molding efficiency. In the thermal vent process layout, the company innovatively adopts a sequential core-pulling mechanism, prioritizing thermal vent ejection before mold release. This method effectively eliminates defects such as plastic part lifting and flash, achieving a qualified rate exceeding 99.5%.
Structural Innovation for Aesthetic Surface Joint Precision: Visual Seamless Joint Clamping System with Advanced Material Processing
To address the aesthetic surface joint precision challenges in 3C product manufacturing, Jingmu Mold has developed a Visual Seamless Joint Clamping System. This system integrates precision laser positioning and a zero-flash design standard, ensuring joint gap ≤0.01mm and completely eliminating surface protrusion defects.
Mold Core:
High-grade Mold Steel S136: Selected for the main mold structure, ensuring dimensional stability.
ASSAB Imported S136 for Slides: Enhanced with vacuum hardening + cryogenic treatment (-196°C liquid nitrogen quenching) to improve toughness and wear resistance.
Core Components:
Mirror Polishing & Nitriding Treatment: Achieves surface hardness HRC50-52+ on cavity surfaces, reducing friction and prolonging service life.
Mold Base:
Lung Kee Mold Base: Provides robust structural support, enabling an actual mold lifespan of 800,000+ cycles, meeting stringent mass production standards for premium 3C products.
Closed-Loop Process Control System: Sequence-Based Machining and Digital Precision Management
Jingmu Mold has established a sequence-based machining and digital precision management system, enabling full-process quality control with sub-millimeter accuracy:
In-Process Coordinate Measurement:
Utilizes Hexagon Metrology systems to perform ±0.005mm-level inspections on critical parameters such as slide machining accuracy and cavity dimensions.
SPC Monitoring + Thermal Deformation Compensation:
Real-time data acquisition dynamically adjusts toolpath strategies, compensating for thermal distortion errors (e.g., mold temperature fluctuations ≤±2°C).
Cumulative Tolerance Band Control:
Strictly limits tolerances on parting surfaces, assembly interfaces, and other core areas to ±0.05mm, ensuring geometric consistency.
Precision Polishing & Assembly Process:
Combines mold temperature balancing (±2°C control) with mirror finishing to guarantee dimensional stability within ±0.03mm for mass-produced components.
Successfully applied to 5G communication module molds for supply chain partners including ASUS and Midea, achieving:
48-hour rapid delivery cycles
Million-unit stable mass production with 99.95% yield rate
