What is DFMA?

DFMA stands for Design for Manufacturing and Assembly. DFMA is designed to ensure product design at lower cost, shorter time and higher quality by improving product manufacturability and assimilability on the premise of taking product functionality, appearance and reliability into consideration.


Manufacturability refers to the ability of a part to be manufactured at a lower cost and higher quality. If the manufacturability of a part is high, then it means that the part meets the design requirements of the manufacturing process, it is easy to manufacture, the manufacturing efficiency is high, cost is low, defects are few, and quality is high.


Assemblability refers to the ability of a product to be assembled at a lower cost and higher quality. The high assemblability of a product indicates that the design of the product satisfies the design requirements of the assembly process. The product is easy to assemble, has high assembly efficiency, low assembly failure rate and assembly cost, and high assembly quality.


Fewer Product Design Modification Times

The core of applying DFMA during product development is “design fully considering manufacturing requirements.” and “doing things right at the first time.” Then it could reduce the design modification times at beginning.

Higher Product Quality and Sustainability

DFMA makes products with high manufacturability and assemblability. Product design has been optimized and improved in the initial stage of product development, so as to avoid the quality problems in the later manufacturing and assembly of products and greatly improve the quality of products.

Lower Product Cost

DFMA could save more than 70% money for new production development. Through reduce the design modification times, part numbers and shortens assembly time reach to save money.

Shorter Product Development Cycle

Compare with the traditional production development, DFMA could save more than 30% times.

Case for DFMA at RPWORLD

Technical issue: Part have a shrinkage risk at red pointed area, we suggest that add 2x grooves on core side to weaken the defects.

Technical issue: Pointed groove is too narrow, which will let mold structure don’t have enough strength, we suggest that enlarge them to 1.5mm to weaken the defects.

Technical issue: 4x kiss-off positions don't have draft angle, which will decrease the mold's lifecycle, we suggest that add draft angle for them as showed as proposal.

Technical issue: Part can hang up in right angle, we suggest the slope instead of right angle to let the part fall into the place.

Technical issue: Part must be released before it is located, making it difficult to align, we suggest that the part is higher than the container, as it will be located before releasing.
