Don’t Choose Rare Materials
When you’re trying to create something new, it’s easy to choose rare or unusual materials. Because you think they might be better, but doing so usually costs a lot of money.
Cost Implications: Using rare materials can make production costs go through the roof. Not only are these materials expensive to purchase, but they may also need to be handled and processed in specific ways, which adds to the cost.
Advantages of common materials: These materials are easy to find and have been in use for a long time. In addition to being reliable, they are easy to find. And the prices are often much lower than those of comparable materials in the West. In addition, improvements in processing methods have made these materials comparable to, if not better than, rarer materials.
The choice of material depends on more than just price. This decision has a direct impact on the quality of the product, its performance, and even its performance in the marketplace. Finding the right balance between reducing costs and ensuring results meet or exceed expectations is no easy task.
Focus on Material Market Dynamics
Like any other market, material markets have their ups and downs. A proactive strategy in when and how you acquire supplies can result in significant cost savings.
Monitoring Importance: Metal prices can change for a variety of reasons, such as global events or supply chain issues. If companies keep a close eye on these changes, they can make informed sourcing choices.
Supply Chain Dynamics: In addition to material prices, supply chain dynamics can affect the actual cost of acquiring materials. A deal that looks good at first can quickly turn sour if freight costs rise or deliveries are delayed for no apparent reason.
Additionally, planning advance orders can avoid rush fees, and communicating with suppliers ensures stable raw material delivery times. This helps stabilize costs and reduce unexpected expenses.
Design and Material Optimization
Optimize parts and material design to improve nesting efficiency and utilization, ensuring no over-design.
Maximize Material Utilization: Design parts for efficient nesting to reduce scrap. Even minor design changes can significantly improve material utilization and lower costs. For example, adjusting part shapes to optimize sheet layout can reduce scrap rates by 10-20%.
Choose Standardized Components: Use standard holes, slots, and thicknesses to leverage standard tools, reducing custom tooling costs. This not only simplifies production but also minimizes tool inventory needs.
Select Appropriate Materials: When quality standards allow, choose softer, less abrasive materials as they require less stamping force and are cheaper. Avoid using high-strength materials unless necessary.
Consider Material Thickness: Avoid over-designing by not selecting materials or thicknesses with excessive strength. This can directly reduce material usage and processing energy consumption.
Use Coining: Replace expensive secondary processes like edge grinding or deburring with coining to create smoother, stronger edges. This minimizes rework and improves process efficiency.
Reducing Waste
Waste is bad when it comes to machining parts or components. Not only does it mean lost materials and money, but it also has a much larger negative impact.
Financial impact: Scrap means a loss of resources. Anything that doesn’t make it into the end result costs money that can’t be used. It also costs money to dispose of or reuse trash.
Environmental Impact: Too much waste can damage the environment. Manufacturing already leaves a huge carbon footprint, and unwanted waste can make that impact even worse.
Ways to reduce waste:
- Use precision stamping techniques.
- Use computer-aided design (CAD) tools to make the most of available materials.
- Regularly maintain and adjust machines to ensure they are working properly.
Tool and Process Efficiency
Tools are the unsung heroes of metal stamping. They shape, cut, and mold the material into the desired product. To ensure the creation process runs smoothly, tools must be optimized.
Select Appropriate Tools: Using the right tools ensures accuracy, reduces the chances of error, and improves the quality of the end result. It’s not enough to have the right tool; it’s necessary to have the correct one.
Minimize Tool Changes: Design parts to reduce the frequency of repairs or reworking.
Tool Maintenance and Costs: Regularly maintain tools so they work better and avoid unexpected breakdowns that halt production. Maintenance costs money, but the cost of a damaged tool, replacement, or a faulty product can be even higher. Implement predictive maintenance using data analysis to determine when a tool needs servicing.
Simplify Processes: Minimize the number of part handling operations, as fewer steps usually lower costs.
Invest in Progressive Dies: For high-volume production, the initial investment in progressive dies can significantly reduce per-piece costs.
Optimization Tips: Follow tool usage instructions; store them properly to prevent wear; extend tool life to reduce unnecessary maintenance. Optimizing tools isn’t just about reducing maintenance costs. It improves productivity, reduces waste, and extends service life. It’s a long-term investment that pays off handsomely.
Realize Automation
Thanks to Industry 4.0, automation has become very important in production. This has many benefits, especially in the metal stamping sector.
Benefits:
- Efficiency: Automated processes can run 24 hours a day, so output rates remain constant.

- Safety: Automation allows for dangerous tasks to be performed, thus reducing the chances of injury on the job.
Cost Reduction:
- Labor Costs: Automation can reduce the need for labor, especially for repetitive jobs.
- Energy Efficiency: Most modern automated tools use less energy, which means you can save on your electricity bill.
- Waste Reduction: Accuracy means fewer mistakes and less material waste.
Automation can save time and money, but it costs money to install in the first place. In addition, too much automation can reduce flexibility and make it difficult to respond to rapid changes in the market or special orders.
Collaboration and Planning
A good manufacturing process depends on knowledge of production, tools, and materials, but also on the expertise of specialized engineers. Communicating with a manufacturing engineer is an important step in changing everything.
Benefits of Expert Advice:
- Process Optimization: Manufacturing experts can identify inefficiencies or bottlenecks in the production process and suggest improvements.
- Materials Insight: Their knowledge can help you choose the right materials to get the best results without spending too much.
- Tooling Advice: They can provide tooling changes or upgrades that can improve production quality and speed.
Working with a manufacturing engineer allows you to do more than just utilize their knowledge. They look at production workflow, material selection, and tooling use with fresh eyes, often identifying problems or opportunities that someone already working on the project may have missed.
Conduct DFM Analysis: Obtain Design for Manufacturability (DFM) analysis from your stamping partner to identify cost-saving opportunities early in the process.
Collaborate with Capable Suppliers: Choose a metal stamping supplier capable of handling projects from prototyping to high-volume production, ensuring they can help optimize designs for cost savings.
Advance Your Supply Chain: Communicate and plan with your suppliers to provide raw material lead times and avoid expensive rush shipments.
Large-Scale Production Optimization
Metal stamping is inherently cost-effective for high-volume production, so increasing production run sizes can dramatically lower per-part costs.
Leverage High Volumes: Increase production run scales to spread fixed costs, such as tooling and setup expenses.
Optimize for Production Runs: High-volume production provides opportunities to revisit designs and implement cost-saving modifications that may not be feasible for small batches. For example, adjusting tools or materials for higher efficiency.
Benefits: Improved efficiency, greater quality consistency, reduced errors and downtime.
Simple Improvements in Design
When we try to get things just right, sometimes the smallest changes can have the greatest effect. Designs that are continually evaluated and improved save money and make products work better.
Simple Design Changes:
- Reduce Materials: Make parts thinner or use alternative materials without compromising quality.
- Simplify Assembly: Reduce the number of parts or simplify the process to speed up production and reduce errors.
- Optimize Tooling: If the design is changed to better fit current tooling, custom tooling may no longer be needed.
Simple changes to the design can save a lot of money but must be done with caution. These changes may affect the product’s functionality, longevity, or user experience. It is important to reduce costs while ensuring product quality.
