3 things to know about Design for manufacturing

Before getting into details, it is important to define the meaning of Design for manufacturing: this expression defines the design process of components or products whose goal is to produce them at the lowest possible cost, without affecting performance. This result is obtained thanks to simplification, optimization and completion of product design.

DFM or DFMA stands for ‘Design for manufacturing and Assembly’.

DFM is necessary for specific and precise operations, as it may be a rather expensive process if realized during the final steps of product development. In fact, improvements result more difficult and expensive to implement during late project development and planning.

Manufacturing design is usually accomplished after concept consolidation, prototype realization and positive test completion for final design purposes.

Why Design for manufacturing is so important?

Design for manufacturing  is essential for different reasons. Here are the main benefits, as follow:

  • Simple production process
  • Improved quality product
  • Reduced price
  • Shorter time-to-market
  • Greater production scalability
  • More sustainable product
  • Reduced production waste cost
  • Reduced risk for new product development: identification of possible production issues since the very beginning of project planning

Design for manufacturing factors

Five are the basic factors to take into consideration:

  • Production process: it must be proper to each product. Besides, it must be tuned on the order quantity, it requires the right choice of material, product specification, tolerances required and extra production processes if necessary.
  • Design: It must respect the principles of product compliance for proper product design and production process.
  • Material: it is important to select the right material for production and consult the Contract manufacturer for getting low-price materials easily, and reliable supply.
  • Environment: where it will be placed and subjected to.
  • Conformity: it must respect the principles of product compliance with security and quality standard.

Design for manufacturing influential factors

Some influential factors are significant for product performance and cost optimization, such as:

  • Number of product parts. Simplify the project with a limited number of product parts or less engineering requests, operations and materials needed.
  • Standard of parts and materials. Utilizing standard parts may reduce cost and time for production, guaranteeing a high-quality result.
  • Modular design creation. Modules simplifyany future product project re-plan, utilizing the same modules for other projects and standard parts.
  • Assembly of parts without screws, fasteners or adhesives. This allows significant savings as screws, for example, add only about 5% to the cost of the material, but 75% to the assembly labor. If fastening elements are required, it is advisable to use standard ones as much as possible;
  • Sales forecast. Estimating a more expensive production process in case of massive production.

Considering that:

  • 70% of production cost is estimated for initial project planning
  • A late product re-work is 13 times more expensive than an early project planning
  • DFM reduces time-to-market at 40%

Design for manufacturing is essential for creating a new product.
