Foshan Dijie Hardware Mold Co., Ltd. specializes in the design and manufacturing of high-precision, heavy-duty aluminum extrusion dies for the demanding automotive industry. Our dies are engineered to produce robust, complex, and tight-tolerance aluminum profiles that meet the rigorous standards of safety, performance, and efficiency required in modern vehicles. From electric vehicle (EV) battery enclosures to structural body members, we provide the tooling foundation for innovation and quality.

Key Features & Advantages:

• Unmatched Precision & Consistency: Utilizing state-of-the-art CNC machining centers, CNC wire-cutting EDM, and Swiss/ Taiwanese slow wire-cutting technology, we guarantee exceptional dimensional accuracy and surface finish for every profile, ensuring consistent performance across long production runs.

• Superior Die Longevity & Stability: Crafted from premium, heat-treated alloy steels and employing advanced die design principles, our extrusion dies offer extended service life and remarkable stability under high-temperature and high-pressure conditions, reducing downtime and cost per part.

• Optimized for Automotive Performance: Our engineering team possesses deep expertise in material flow and thermal dynamics. We design dies that ensure uniform mechanical properties and precise grain structure in the extruded profiles, critical for automotive strength and durability requirements.

• Comprehensive Solution Provider: We offer an integrated service from initial design consultation and prototyping to mass production and technical support. Our team works closely with clients to optimize profile design for manufacturability and cost-effectiveness.

• Rigorous Quality Assurance: Every die undergoes a stringent inspection process, coordinated with our ISO 9001:2008 certified quality management system. We utilize precision measuring instruments like CMMs and profilometers to ensure every detail meets specifications.

Technical Specifications:

• Die Material: Premium H13 hot-work steel, SKD61, or other customized alloys, vacuum heat-treated for optimal hardness and toughness.

• Manufacturing Process: CNC machining, Precision Grinding, CNC Electrical Discharge Machining (EDM), Slow Wire-Cutting.

• Typical Tolerance: ±0.05mm or as per customer's specific requirements.
