VINACNC - Expert in High-Precision DIN 9845-A Guide Bushes for Die Molds

In the mould and stamping industry, a guide bush is a core component that determines the precision and lifespan of a die mold. VINACNC is proud to supply high-precision DIN 9845-A guide bushes with high hardness and tight tolerances, ensuring superior performance and durability even under harsh production conditions.

Technical Specifications, Materials, and Applications

• Materials: The products are crafted from high-quality tool steels such as SKD-11, M2, or premium materials like Tungsten Carbide. These materials are known for their high hardness, wear resistance, and toughness after heat treatment.

• Standards:

  • DIN 9845-A: The guide bushes are manufactured to the international standard DIN 9845-A, ensuring high compatibility and quality.

• Technical Properties:

  • High Precision: The products are CNC machined with extremely tight diameter tolerances, ensuring a perfect fit with the guide pin and a smooth mold closing/opening process.

  • Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 58-62°), allowing the guide bush to withstand high pressure and friction during continuous operation.

  • Surface Finish: The surface is specially treated to achieve high smoothness, which reduces friction and extends the lifespan of the components.

• Applications: Guide bushes are indispensable components in stamping dies for cutting and punching holes in sheet metal or plastic parts. They are widely used in industries producing automotive parts, electronic device housings, and precision machinery.

Product Advantages

• Superior Durability: With high-quality steel materials, the guide bushes resist repetitive force and friction, significantly extending the mould's lifespan.

• Absolute Precision: Dimensions are strictly controlled down to the micrometer level, ensuring the components operate in perfect conjunction, minimizing the risk of product defects.

• Optimized Performance: The smooth operation helps to reduce the stamping cycle time and enhances overall production efficiency.

• International Standard Compliance: Manufacturing according to DIN 9845-A standards ensures high compatibility and quality, making it easier for clients to integrate our components into their existing systems.

Post-Machining Product Inspection Process

1. Hardness Test: We use a professional hardness tester to verify the hardness of the heat-treated material.

2. Dimensional and Tolerance Check: We use a Coordinate Measuring Machine (CMM) to verify all critical dimensions and tolerances against the technical drawings.

3. Surface Inspection: We use a surface roughness tester and visual inspection to ensure there are no cracks, scratches, or other defects.

4. Functional Test: The components are test-fitted with related parts to ensure a perfect fit and smooth operation.

Packaging and Storage Process

• Cleaning and Rust Prevention: The guide bushes are cleaned and coated with a specialized anti-rust oil to protect their precision surfaces.

• Secure Packaging: Products are carefully packed in rigid plastic boxes or cardboard crates with foam to prevent damage during transport.

• Information Labeling: The packaging is clearly labeled with product information, including the product code, dimensions, and handling instructions.

• Storage Instructions: We recommend storing the products in a dry, cool environment, away from high humidity and corrosive chemicals.
