DFM（Design For Manufacturability）
DFM is an acronym for “Design For Manufacturability”, which means we extensively study the 3D/CAD files you provide and make sure your design can be built as you intended. Then we will provide you a report for each part that summarizes the part information (size, weight, material, finish, color, etc.) and addresses any concerns regarding mould making or part design. Not only that, but the DFM we provide also includes our recommendations on how to resolve any issues best to help you revise the design if necessary. In every manufacturing process, it is essential to ensure that every stage is foolproof and executed appropriately. From material selection all the way to actual manufacturing, it is essential to find a balance between cost and quality. In the injection molding process, the injection molding design for manufacturability(DFM) is the process that ensures all the above is adhered to.
Injection molding design for manufacturability basically has to do with the improvement and enhancement of your part design. It ensures that your part is economically fit for production, easy to produce, and fulfills its functional duties. However, DFM doesn’t only deal with the injection molding design. It also covers selecting the suitable materials, the injection molding mould design, evaluating product lead time, quality, hazard associated with use, and so on.
Five principles of DFM:
Process, design, material, environment, compliance/testing.
Advantages of DFM:
* Quicker lead time
* Quicker time to market
* Reduction of production cost
* Higher quality of parts
* Reduces wastage
The importance of DFM:
* Guarantee of manufacturing feasibility
* Prevention of part failure
* Determination of the complexities of manufacturing
