Designing for Success: Optimal Part Design for Forging with WALKSON

Introduction:

At WALKSON, we believe that the journey to producing high-quality steel closed-die forging parts begins with design. The right design not only ensures manufacturability but also maximizes the inherent advantages of forging, such as strength, durability, and precision. Here’s how you can design parts for optimal forging outcomes, leveraging our expertise to turn concepts into robust components.

Key Design Considerations for Forging:

1. Material Selection:

Compatibility: Choose materials that are well-suited for forging. For steel, consider the forging temperature, final mechanical properties, and the part's intended use. WALKSON can advise on the best steel grades for your application.

2. Geometry and Shape:

Simplicity vs. Complexity: While forging can handle complex shapes, simpler geometries reduce tooling costs and potential defects.

• Avoid Sharp Corners: Use radii where possible to improve material flow and prevent cracking.

• Uniform Wall Thickness: Helps in even cooling and reduces the risk of warping or internal stress.

Draft Angles: Incorporate draft angles on all vertical walls to facilitate part ejection from the die, typically 3° to 7°.

3. Part Size and Proportions:

Size Limitations: Be aware of the capacity of the forging equipment. Larger parts might require multiple forging steps or specialized equipment.

Aspect Ratios: Long, thin sections can be challenging to forge uniformly; consider segmenting or altering the design for better material flow.

4. Flash and Trim Considerations:

Flash Lines: Design parts to minimize flash or ensure it's in areas where it can be easily removed without affecting functionality.

Trimming: Consider how the part will be trimmed post-forging; design should allow for clean, efficient removal of excess material.

5. Grain Flow:

Directional Strength: Design your part to leverage the natural grain flow of the forged metal, enhancing strength along load paths.

Avoid Cross-Section Changes: Abrupt changes can disrupt grain flow, leading to weak points. Use gradual transitions if necessary.

6. Tolerances and Machining:

Forging Tolerances: Understand that closed-die forging can achieve tight tolerances, but not all dimensions might be forgeable to final size.

•  Machining Allowance: Plan for minimal post-forging machining by designing parts close to final dimensions where possible, but include allowances for necessary finishing.

7. Heat Treatment and Surface Finish:

Design for Treatment: If heat treatment is required, consider how it might affect the part's shape or surface. Design to accommodate potential distortion.

Surface Texture: Specify the desired surface finish, knowing that forging can provide a good base but may need further treatment for finer finishes.

WALKSON’s Role in Design Optimization:

• Consultation: Our engineers work with you from the conceptual stage, offering insights on design for manufacturability and performance.

• Simulation: We use advanced simulation tools to predict how your design will behave during forging, allowing for preemptive design adjustments.

• Prototyping: We might suggest or create prototypes to test design concepts before full production, ensuring the design is forge-friendly.

• Custom Tooling: When necessary, we design and manufacture dies tailored to your part’s unique requirements, ensuring optimal forging outcomes.

Benefits of Designing for Forging with WALKSON:

• Reduced Production Costs: Effective design minimizes material waste, reduces machining needs, and optimizes tooling.

• Improved Part Quality: By designing with forging in mind, you enhance strength, durability, and part integrity.

• Faster Time to Market: Fewer iterations and less post-forging work mean quicker production cycles.

• Tailored Performance: Parts are not just made; they're engineered for their specific use case, leveraging forging's benefits.

Conclusion:

Designing for optimal forging is about marrying creativity with practicality. At WALKSON, we guide you through this process, ensuring that your steel parts are not only manufacturable but also perform at their best. Whether for automotive, aerospace, or any industry, let's design together for forging excellence.
