How to make sheet metal parts cheaper?

Are you looking for ways to reduce costs in the manufacturing process, or are you exploring material and design changes?

To make sheet metal parts cheaper, consider optimizing your design for minimal material use, using standard sizes to reduce waste, and choosing cost-effective materials. Additionally, streamlining the manufacturing process and increasing production volume can lower unit costs.

If you’re sourcing sheet metal parts or thinking about it in the future, read on to see how to optimize costs from design to production.

You might want to explore techniques like reducing complexity in the design, using automated machinery for efficiency, and sourcing materials in bulk. Delve into cost-effective manufacturing methods and ensure your design aligns with standard production practices.

Designing sheet metal parts effectively involves several considerations to ensure cost-efficiency, functionality, and manufacturability. Here are some key steps and tips to help you design sheet metal parts:

1. Understand the Requirements:

Functionality: Define the part’s purpose and how it will be used.

Load and Stress: Consider any mechanical stresses the part will encounter.

2. Choose the Right Material:

Material Type: Select materials that meet strength, weight, and cost requirements (e.g., steel, aluminum, stainless steel).

Thickness: Choose the appropriate thickness based on strength needs and manufacturing capabilities.

3. Optimize Design for Manufacturing:

Standardize Dimensions: Use standard sheet sizes and thicknesses to reduce material costs and waste.

Minimize Waste: Design parts to fit efficiently on standard sheet sizes.

Avoid Complex Shapes: Simpler designs are easier and cheaper to manufacture.

4. Design for Fabrication:

Bending: Ensure that the part design allows for the bending process, including the bend radius and allowances.

Cutting: Design with cutting processes in mind, such as laser cutting or punch pressing.

Forming: Consider the capabilities of forming processes and design accordingly.

5. Incorporate Features Efficiently:

Holes and Slots: Design with appropriate sizes and locations for holes and slots to avoid excessive tooling changes.

Tabs and Slots: Use tabs and slots for alignment and assembly where possible to minimize additional fasteners or welding.

6. Consider Assembly and Joining Methods:

Rivets, Welds, or Screws: Choose joining methods that are cost-effective and easy to implement.

Tabs and Slots: Incorporate these to reduce or eliminate the need for additional hardware.

7. Use CAD Software:

3D Modeling: Use CAD software to create detailed models and simulations to assess fit, function, and manufacturability.

Prototype: Use rapid prototyping to test designs before full-scale production.

8. Review Tolerances:

Tolerances: Set realistic tolerances to avoid excessive rework or scrap. Tight tolerances can increase manufacturing costs.

9. Leverage Advanced Technologies:

Automation: Use CNC machines or automated presses to increase efficiency and reduce labor costs.

Advanced Techniques: Consider using techniques like hydroforming if they provide cost benefits.

10. Collaborate with Manufacturers:

Feedback: Work with manufacturers early in the design process to get feedback on potential cost-saving modifications.

Tooling: Discuss tooling requirements to ensure that your design is feasible within the desired cost constraints.

By following these guidelines, you can create sheet metal parts that are not only functional but also cost-effective to manufacture.
