DFM & Design for Assemble

We, at On Hing Metal will provide a Design for Manufacturing (DFM) analysis before quoting any assembly process. This will result in manufacturing time and costs. 

DFM (Design or Manufacture) or DFA (Design or Assemble) is a design process or concept where a product contains as few parts as possible, fewer pieces to fabricate, and less cost. With a minimal number of pieces, it is easier to assemble a product, which in turn, is time-saving and cost-saving.

Reducing time-to-market and total production costs by prioritizing both the ease of manufacture for the product's parts and the simplified assembly of those parts into the final product. For example, even something as simple as changing a draft angle on a specific feature on a product or changing a hole to a different place can impact the production time significantly. In addition, using the proper material or a mixture of materials for a particular function for a specific technical detail would also save material costs.

In terms of accuracy for small parts, a reproducible dimensional tolerance3 of less than 0.03-0.06mm can be maintained with zinc castings, and aluminum castings are 0.07-0.10mm. Knowing the tolerance can decrease the areas for CNC machining.
