Why We Ask Our Customers to Provide 3D CAD Models with RFQs

Providing 3D CAD models with rfqs removes ambiguity and results iN more competitive pricing

When we receive a request for quote (RFQ) from a customer, if they only provided 2D drawings, unless it is something very simple, we are going to ask for a 3D model.


Asking customers for 3D models when providing machining quotes offers several advantages and benefits. Here are some reasons why it is a common practice:


Accuracy: 3D models provide a precise representation of the customer's desired part or component. They contain detailed information about dimensions, geometries, and features. By working with an accurate 3D model, we can better understand the complexity of the part, enabling us to provide the most competitive quote possible by removing as much ambiguity as possible.


CNC Simulation: Often the best way to accurately determine how long it would take to machine a part is to perform a digital simulation using CAM software. The input for our CAM software in a 3D CAD model.


Saves Money and Reduces Risk: If our customer does not have a 3D CAD model, most likely we will have to create one. Not only does that add engineering costs to the quote, but it also adds risk as there is a possibility for error or misunderstanding the 2D geometry when we created the 3D CAD model.


Visualization: 3D models allow both the customer and the us to visualize the final product before it is manufactured. This visualization helps ensure that everyone involved has a clear understanding of the design intent, reducing the chances of miscommunication or misunderstandings. It also enables the machinist to identify any potential issues or challenges in the machining process, allowing for early problem-solving and revisions if necessary.


Feasibility Assessment: Machining a part involves various processes such as milling, turning, drilling, EDM, or grinding. Having a 3D model helps us evaluate the feasibility of manufacturing the part based on its design and geometry. We can assess if the required features can be achieved with the available tools and machinery, identify potential areas of difficulty, and propose alternatives or optimizations to improve manufacturability and reduce costs.


Time and Cost Estimation: A 3D model provides essential information for estimating the time and cost involved in machining the part. We can analyze the complexity, material requirements, and machining operations needed to produce the component accurately. This allows us to determine the necessary resources, machine setup time, tooling requirements, and labor costs, resulting in a more reliable and detailed quote.


Quoting Efficiency: Requesting 3D models as part of the quoting process streamlines communication and reduces back-and-forth exchanges with the customer. With a 3D model at hand, our machinists can evaluate the part more comprehensively, provide a quicker response, and generate a more precise quote. It saves time for both parties involved and helps expedite the overall quoting process.


By asking for 3D models when providing machining quotes, we can ensure accuracy, improve communication, assess feasibility, estimate time and costs more effectively, and enhance overall efficiency in delivering a competitive and reliable quote to the customer.

The Declining Population of China: Implications for Global Supply Chains and Consumer Prices I  China's population has been shrinking since 2022, and the United Nations has predicted that it could drop to 1.3 billion by 2050 and 770 million by 2100. This is due to fewer newborns and more deaths from an aging population. The population is expected to fall by 20 million to 1.39 billion by 2035 Understanding the Decline China, known for having the world’s largest population, is experiencing a decline that could reshape its economic and global trade role. The decline is attributed to several factors, including lower birth rates, aging population, and stringent past policies like the one-child policy. The effects of this demographic change are beginning to ripple across various sectors, particularly impacting manufacturing and the global supply chains that depend heavily on Chinese labor and production capabilities. Impact on Global Supply Chains 1. Increased Production Costs: China has long been the world’s factory, known for its cost-effective labor which has enabled lower production costs globally. However, as the working-age population shrinks, there will likely be a shortage of labor which could drive up labor costs due to the increased competition for workers. Higher labor costs in China could lead to increased manufacturing costs, which might force companies to reassess their production and supply chain strategies. 2. Shifts in Manufacturing Hubs: With rising costs in China, companies might look to diversify their manufacturing locations to other countries with younger populations and lower wage expectations, such as India or Vietnam. This shift could lead to a reconfiguration of supply chain networks, which may result in initial disruptions and increased costs as new systems and infrastructures are put in place. 3. Technological Investment and Automation: To counteract the labor shortage, there might be an accelerated investment in automation and robotics. While this could mitigate the impact of reduced labor availability in the short term, it also requires significant upfront investment and could lead to a greater concentration of technical expertise rather than widespread labor benefits. Effect on Consumer Prices 1. Increase in Product Prices: As production costs rise due to higher labor costs and potential tariffs from diversified supply chains, consumer prices are likely to increase. Products that are heavily dependent on Chinese manufacturing, such as electronics and textiles, could see significant price hikes. 2. Fluctuations in Supply and Demand: A reduced population also means a decrease in domestic consumption within China. For international businesses, this represents a dual challenge: navigating the increase in production costs and adjusting to a potentially reduced Chinese consumer market. However, this could also lead to an excess of goods, which might temporarily lower prices in other markets until supply chains adjust. 3. Global Market Adjustments: The global market will need to adjust to these shifts. Countries and companies that adapt quickly, diversifying their markets and supply sources or investing in automation, will likely fare better. Consumer prices will stabilize over time, but the initial impact could be significant depending on the industry and the speed of demographic changes. Conclusion The declining population in China is a harbinger of significant changes in global supply chains and economic structures. As companies and countries navigate this new demographic landscape, the impacts on production costs, supply chain logistics, and consumer prices will become increasingly apparent. Adapting to these changes will require strategic planning, investment in technology, and diversification of supply and market bases. The global economy is on the brink of a significant transformation, and understanding these dynamics is crucial for stakeholders at all levels.
