Designing for Manufacture and Assembly (DFMA) – The Guided Approach



Products designed using DFMA principles are extraordinarily reliable than those which are developed through the traditional layout technique. DFMA ensures a unbroken, smooth and brief transition from design segment to manufacturing segment too

Advantages of the usage of DFMA

One of the primary blessings of the usage of DFMA is the decrease assembly cost and brief meeting duration. Also the time to marketplace time is short sufficient. DFMA permit you to lower assembly prices via using fewer components and removing the ones which are not as essential, thus reducing the labour effort too. With popular meeting practices together with vertical assembly and self-aligning components, the technique lessens assembly time involved too.

Steps to take for Efficient Manufacture and Assembly

  • Minimize Part Count

The very last rate of a product is proportional to quantity of elements and subsequently discount in range of components product great and reliability normally increase. With fewer components to worry about, there are reduced possibilities of misalignment.

One should ask whether the element can pass relative to other component while performing its function, whether or not the part can be made of various cloth than the others and additionally whether it have to be a separate element.

If the solution is "NO", then the possibility of mixing the component with others have to be considered.

  • Make all Parts Multi-Functional

Multi-purposeful parts supply several functions in one element which in turns reduces complexity substantially.

  • Reduce The Number of Screws and its Types

Using much less fasteners reduces meeting weight, the overall fee, and even its complexity. One have to instead contain self-aligning functions inside the layout. If fasteners are vital to the design, then the use of a not unusual length will assist.

  • Facilitate Better Parts Handling

Parts have to constantly be designed with efficient dealing with in thoughts. They have to reduce the overall ability for getting stuck collectively. Also it does not require special furnishings for assembly. The components need to be without problems identifiable too specially for speeds dealing with. Use uneven capabilities while precise orientation could be in pressure for proper alignment.

  • Use Standard Parts and Hardware

Use standard components as a part of the design in order that it reduces the wide variety of various gear required for the overall assembly and reduce its fees. It is better to by no means design a component that can be derived from a catalog. One can use diverse sources like preferred parts lists, vendor catalogs etc too.

  • Encourage Modular Assembly

Modular designs assist in simplifying assembly operations and identifying the troubles will become pretty smooth ultimately. It additionally eases the inventory system and boosts preservation and serviceability. The normal repair time is decreased in this context too.
