How can your design reduce manufacturing costs without sacrificing quality?

Selecting the right material is crucial for reducing manufacturing costs without compromising quality. Engineers should consider materials that offer a balance between performance and cost. Utilizing materials that are readily available and easy to process can significantly cut down on production expenses. For instance, using high-strength alloys or composites can reduce the amount of material needed while maintaining structural integrity. Additionally, sourcing materials locally can reduce transportation costs and lead times. Recycling and using sustainable materials can also be a cost-effective choice, aligning with both environmental and economic goals.

Reduce the number of parts and components where possible without compromising functionality Use standardized components to leverage economies of scale and reduce procurement costs Optimize designs for manufacturability (DFM) to minimize complexity and streamline production processes Choose materials that balance cost and performance requirements Optimize material usage to minimize waste and scrap during manufacturing Consider alternative materials that offer similar performance at lower cost Adopt automation where feasible to reduce labor cost and increase production throughput Negotiate favorable terms with suppliers for bulk purchasing or long-term contracts to secure cost savings Minimize rework and scrap with effective practices

When designing a product, selecting the right materials can significantly impact both cost and quality. Opting for readily available and easy-to-work materials can reduce processing time and waste, enhancing efficiency. Using standardized material sizes and grades allows for bulk purchasing, minimizing custom orders and lowering costs. Additionally, consider alternative materials with similar properties at reduced costs, ensuring they meet quality specifications for functionality and longevity. By carefully choosing materials, you can balance cost-effectiveness and high quality, leading to a more successful product.

So many existing strategies to optimize material selection! Engineering needs to design to ensure minimal mass while ensuring different performance criteria are met. Purchasing is pressured to ensure cost control through bulk buys, commonization across products, and supplier leverage. Logistics must manage supply, handling and transport from supplier to production. Ed Demming pointed out that “suboptimization” of each of these without consideration of overall impact is a real cost risk. Take the blinders off, and manage your project for best overall impact of material selection. This likely requires some sacrifice in a subprocess to ensure best overall performance. Don’t let group kpi drive poor decisions for the overall project!

Designing parts with the manufacturing environment and the end products environment in mind can significantly decrease the chances of defects. Every time the part changes hands is an opportunity for failure.

Keep It Simple Stupid! Just because you can design something does not mean you should. Again, focusing on the big picture is critical. For example, combining components in design to simplify assembly is generally a great idea, but if this drives exotic tooling that’s costly and difficult to maintain, you may need to consider multiple components. Highly skilled line workers can create great value for the customer, but clever design reduces the need for excessive finesse needs in production. Take advantage of skilled technical manufacturing when it is needed, and drive simplicity into manufacturing operations wherever possible to support best quality practices.

Too many designers only give DFM “lip service”, and fail to really drive the method into product and process development. Over time, DFM has been stressed and then forgotten in cycles. It remains an important method to ensure efficiency and quality by reducing risk of failure in production. The best way to reduce error in a process is to eliminate it, and DFM can keep the designer focused on simplifying and combining steps where possible. This is a really useful mindset.

Leveraging automation, our design reduces manufacturing costs without compromising quality by incorporating automated precision in production. Automated assembly lines and robotic systems ensure consistent accuracy, minimizing human error and reducing waste. Automation speeds up production, significantly lowering labor costs and improving efficiency. Advanced quality control through automated inspections detects defects early, ensuring only top-quality products proceed, reducing rework and scrap. Automation facilitates flexible production, allowing for rapid adjustments and scalability, aligning with market demands while maintaining high standards. This integration of automation streamlines operations and achieving cost efficiency.

Designing products with automation compatibility in mind can significantly reduce manufacturing costs while maintaining quality. Automation in manufacturing processes, such as robotic assembly and automated inspection, increases production speed and consistency. Engineers should design parts that can be easily handled by machines, with features that align with automated tools and systems. This includes considering the size, shape, and orientation of components to facilitate automated assembly. By ensuring that the design is compatible with automation technologies, manufacturers can achieve higher throughput, lower labor costs, and consistent product quality.

One thing I’ve learned is to measure quality as product is being built. Being able to detect defects early, finding root causes and using predictive analytics to model machine performance and tooling wear are key. Using techniques defined in Industry 4.0 enables not only design for manufacturing, but also the digital transformation of the entire line including AI technologies that improve inspection processes (machining processes is a great example). What will happen to the Defense Industrial Base over the next five years will have impact for the next thirty years.

Continuous improvement also involves looking at the factories hidden costs. If you can identify those costs, you will not only improve efficiency on the production floor, but also improve the cost to manufacture margins.
