The Importance of Design For Manufacturability

The Importance of Design For Manufacturability

In the Wikipedia, here is the introduction of  DFM(Design For Manufacturability):

Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering practice of designing products in such a way that they are easy to manufacture. The concept exists in almost all engineering disciplines, but the implementation differs widely depending on the manufacturing technology. DFM describes the process of designing or engineering a product in order to facilitate the manufacturing process in order to reduce its manufacturing costs. DFM will allow potential problems to be fixed in the design phase which is the least expensive place to address them.  Other factors may affect the manufacturability such as the type of raw material, the form of the raw material, dimensional tolerances.

Depending on various types of manufacturing processes there are set guidelines for DFM practices. These DFM guidelines help to precisely define various tolerances, rules and common manufacturing checks related to DFM.

Why is it important in a injection molding process? Here are three reasons to explain:

1.Ensure that your product can actually be manufactured.

After completing the design drawings and prototype to verify the design concept, DFM began. It reinvents the product in a production facility environment rather than in a research and development laboratory or computer simulation. In manufacturing, achieving the design features or system performance of a part can be very challenging. In the worst case, the product design may not even be manufactured, and must be returned to the drawing board.

2.Affect the look, feel, precision and function of the product.

DFM includes all designs for BOM (Bill of Materials) projects and final assembly, such as mold layout, heat transfer analysis, tool design and manufacturing process design. Only by using properly designed tools can the correct appearance, feel, accuracy and function of the product be achieved. For example, a part of the mold will leave parting lines and tool marks on the product. The location of these parting lines will affect the appearance of the product. As part of this process, product designers and tool designers will make and approve these types of decisions.

3.Greatly affect the molding schedule.

When creating a project schedule, we usually ignore the DFM, but this is not the case. Generally speaking, DFM can move back and forth from one week to several weeks, depending on the quality requirements and the complexity. Step by step, it is necessary to verify and confirm every detail of DFM with product designers as much as possible to eliminate potential errors, which may require a lot of time and money to recover at a later stage. It is important to understand that any adjustments during the design process of the manufacturing process will take time and affect the entire schedule. However, in the long run, the returns will be greater.
