Changhui Metals | Professional Custom Processing of Automotive Dashboard Mold Bases from Your Drawings
Dear Client,
Greetings!
Changhui Metals Company, as a professional manufacturer of precision mold bases, hereby formally undertakes the custom manufacturing and processing of automotive dashboard mold bases according to your supplied drawings and materials. We fully understand that the automotive dashboard, as a core interior component, demands extremely high standards for appearance, texture, and assembly precision. The foundation for achieving all this lies first in the "skeleton" that carries its formation—the mold base. We pledge to utilize professional engineering expertise and precision manufacturing capabilities to transform your design blueprint into accurate, reliable, and high-quality mold bases.
I. Why Choose Changhui for Your Automotive Dashboard Mold Base?
We are not just manufacturers, but your in-depth partners in mold solutions. Undertaking processing from supplied drawings means we will strictly adhere to your design specifications and technical requirements, while providing full-process support from drawing review and process optimization to precision manufacturing, ensuring the mold base performance integrates seamlessly with your mold design and injection molding production.
II. Core Technical Strength, Overcoming High-Precision Mold Base Manufacturing Challenges
To meet the stringent demands of automotive dashboard mold bases for dimensional stability, surface flatness, and long-term durability, we have established a mature manufacturing system:
- Scientific Material Selection: Based on your product material (e.g., PP, ABS, PC/ABS) and mass production requirements, we accurately recommend and select premium mold steels, such as P20 or 718 for high polishability, or pre-hardened 2738, S50C for high wear resistance, ensuring the mold base possesses sufficient strength, toughness, and polishability.
- Precision Machining, Ensuring Extreme Accuracy:
- Equipment Matrix: Supported by our equipment fleet of over 64 processing machines, with 35 advanced CNC machining centers at its core, we possess robust capabilities for precision milling, turning, and drilling.
- Accuracy Control: Key areas employ high-precision processes like slow wire cutting (accuracy up to ±0.003mm), combined with large precision grinding, ensuring the mold base's plate flatness, parallelism, and perpendicularity (controllable within 0.01mm/m²), laying a solid foundation for subsequent mold assembly and product forming.
- Stability Treatment, Eliminating Post-Processing Deformation:
- All core plates undergo vibration aging treatment after rough machining, effectively eliminating residual stress generated during machining, preventing deformation during long-term use or storage, and guaranteeing lasting dimensional stability.
III. Standardized Operational Process, Ensuring Consistent Delivery Quality
From the moment we receive your drawings and requirements, a rigorous process is initiated:
- Drawing Review & Process Planning: Engineering team对接, analyzes drawings, confirms technical details, and develops a customized machining process plan.
- Material Preparation & Inspection: Procure as needed or use your supplied standard blanks, followed by strict initial inspection for material and dimensions upon arrival.
- Rough Machining & Stress Relief: Perform processes like milling six sides, roughing, and lifting hole processing, followed by vibration aging treatment to enhance material stability.
- Precision Forming Machining: Core procedures. Utilize CNC for precision milling of cavities, guide pin holes, cooling channel holes, etc.; use precision grinders for fine grinding of plate surfaces; process deep cooling holes via gun drilling, ensuring smooth and uniform water channel flow.
- Finish Machining & Final Treatment: Complete all detailing including fine finishing of sides, drilling and tapping screw holes, and chamfering.
- Full Inspection & Shipping: QC department conducts final full inspection of dimensions and accuracy using high-precision equipment like CMMs. After qualification, products are cleaned, rust-prevented, packaged properly, and delivered on time.
IV. Our Commitment
- Custom to Print, Precise & Reliable: We treat your drawings as the highest production order, ensuring 100% conformity between the physical product and the design.
- Full Collaboration, Rapid Response: A dedicated project liaison is assigned to provide efficient and transparent service, from technical communication to progress updates.
- Quality Traceability, Clear Accountability: Each mold base comes with complete machining and inspection records, ensuring full traceability.
Changhui Metals, backed by the expertise of over a hundred professionals and dozens of precision machines, is committed to being your most reliable partner in mold base manufacturing. Your Blueprint, Our Precision Mold Base. We are here, ready to receive your drawings and discuss collaboration.
