We attach more and more value to high quality products that are sustainable. This includes the production process, which must be as sustainable as possible. Maybe you have read our article about Design for Assembly
and Design for Disassembly
. This article is about Design for Manufacturing (DFM), a crucial part of product development. From metal plastic casting to cleaning and logistics, DFM is used in all kinds of processes. But what is the difference between DFM and DFA?
What is Design for Manufacturing?
Minimizing the complexity of manufacturing operations and reducing costs. Design for Manufacturing (DFM), literally: designing for the manufacturability, is a methodology where the focus is on the manufacturability of the design. It is the technical practice that focuses on the effective and efficient production of parts that form a complete product after assembly. It looks at minimizing the complexity of a part. By optimizing production, quality is improved and production costs can be kept to a minimum.
DFM is crucial for parts that need to be produced in large numbers or when multiple production processes are required. In small quantities, DFM helps to achieve a final design with fewer repetitions and prototypes.
The main advantages of Design for Manufacturing
There are several important advantages of DFM. The first is that without a DFM approach, production problems are revealed when a product is already in production. The right DFM tools can identify problems in the product while it is still in the design process. The second is that DFM not only provide warnings, but also recommendations for solving production problems. Another important advantage is that the potential for lower costs can be seen without affecting the design. Optimizing designs can also help shorten the production and distribution timeline. Finally, Design for Manufacturing can speed up the production development timeline. Instead of waiting for feedback from suppliers on the manufacturability of each design, engineers can analyze this in-house.
Difference Design for Manufacturing and Design for Assembly
It can be useful to know the difference between Design for Manufacturability (DFM) and Design for Assembly (DFA). Design for Assembly (DFA) focuses on designing a product so that it can be easily assembled and disassembled (DFD). This approach focuses on principles such as minimizing the total number of parts, ensuring that parts are easy to insert, and limiting assembly requirements to simple, repeatable movements.
The focus at DFM is on individual parts with the goal of reducing or eliminating complex or unnecessary features that would make production difficult. DFA is focused on reducing and standardizing parts and (sub) assemblies. The goal is to reduce assembly time and costs.
DFM and DFA are both important at an early stage of product design. The primary goal of both methods is to make a product and the associated process as efficient as possible.
Design for Manufacturing is a method to effectively and efficiently produce parts that, after assembly, form a complete product.
Design for Assembly is a design method for a product with the ease of assembly with fewer parts in the product.
Design for Disassembly is a design process that allows products, parts and materials to be easily recovered for reuse.
