Changhui Company: A Professional Manufacturer of Injection Mold Bases
In the field of precision mold manufacturing, the mold base serves as the "skeleton" and foundation of a mold. Its precision, stability, and reliability directly determine the quality and production efficiency of the final injection molded product. Changhui Company is precisely such a professional enterprise specializing in the R&D, machining, and manufacturing of high-quality injection mold bases. We are committed to providing a solid and reliable core support for mold-making enterprises.
1. Core Strengths, Forging a Professional Foundation
Integrating R&D, production, and sales, Changhui Company has become a trusted mold base supplier for numerous partners, relying on strong technical expertise and large-scale production capabilities.
- Scale Operations: The company employs over 100 staff, including an experienced engineering R&D and technical team of more than 30 professionals, as well as over 60 specialized CNC technicians. This provides powerful technical support for the entire process from drawing evaluation to finished product delivery.
- Advanced Equipment Cluster: Equipped with more than 60 sets of advanced production and machining equipment, this forms the robust guarantee for quality and efficiency. Core equipment includes 35 high-precision CNC machining centers, and large gantry machining centers (maximum machining range: X-axis 3500mm, Y-axis 2500mm, Z-axis 1500mm). Notably, the company possesses special equipment like deep-hole drills capable of machining water channel holes up to 1450mm deep, excelling in handling the cooling systems of complex molds.
- Stable Delivery Capacity: Relying on a mature supply chain management and efficient production system, the company boasts an average monthly output value exceeding 8 million RMB, possessing strong capabilities for undertaking large-scale orders and ensuring stable delivery.
2. Precision Manufacturing Process, Interpreting the Philosophy of Quality
We deeply understand that "precision determines everything." Changhui not only possesses advanced machining equipment but also adheres to a rigorous manufacturing process and a comprehensive quality control system throughout production.
- Premium Material Selection: We use customized mold steels characterized by high hardness, high surface brightness, and strong corrosion resistance. All steel materials undergo a 90-day natural aging process upon arrival to fully release internal stresses, followed by strict spectroscopic analysis and flaw detection testing. This ensures stable material performance from the source, laying the foundation for a high product yield rate (achieving over 99%).
- Standardized Process: We strictly follow over ten key procedures including sawing, rough milling, cavity roughing, heat treatment (quenching and tempering), precision grinding of reference surfaces, finish milling, CNC precision machining, drilling and tapping, and benchwork finishing. Among these, the precision grinding of reference surfaces after heat treatment establishes the sole, ultra-high precision positioning datum for all subsequent machining.
- Inspection as the Core: We firmly believe that "precision is achieved through inspection." The company has established a comprehensive inspection system covering raw materials, the manufacturing process, and finished products:
- Incoming Material Inspection: Conducting hardness tests (e.g., Rockwell hardness, compliant with relevant standards) on raw materials.
- Process Monitoring: Utilizing equipment like laser interferometers at key process stages for real-time dimensional monitoring.
- Final Verification: Ultimately relying on high-precision equipment such as Hexagon CMMs for full-dimensional inspection, ensuring critical mold base dimensions and positional tolerances are strictly controlled within 0.02mm, guaranteeing consistency in assembled machining. This system has enabled us to complete all-item precision inspection for complex orders like new energy battery case mold bases within 6 hours, strongly supporting rapid delivery.
3. Comprehensive Services, Meeting Diverse Needs
Changhui Company is customer-centric, offering flexible and comprehensive products and machining services:
- Wide Product Range: Professional manufacturing of various standard and non-standard mold bases, including Big Gate molds, Pin Point Gate molds, Two-Color/Multi-Color molds, and Large molds.
- Comprehensive Machining Capabilities: In addition to providing complete mold bases, we also undertake various customer-supplied material processing, including: machining plates, cavity milling, slider machining, processing of water channel holes/KO (knock-out) holes/spring holes, making support pillars, guide pillar bushings, wear plates, stop pins, and other full-range machining services.
- Customized Solutions: Whether you require standard LKM, FUTABA, or other system mold bases, or have special 2D/3D design drawings, our engineering team can quickly evaluate your needs, optimize solutions, and provide competitive quotations.
Changhui Company has established stable cooperative relationships with excellent enterprises such as Guangdong Keda Intelligent Manufacturing Co., Ltd. and Shenzhen Qunda Xing Precision Mold Co., Ltd.
