Engineering Design Services Information

Engineering design firms provide total design for components, products, and equipment. Companies and individuals that need design work done but do not have the capabilities or resources can turn to an engineering design service to provide the needed work. Finished product requirements are initially laid out and revisited periodically throughout the design process. The finished product can include drawings, bills of material, material specs, and testing standards.

Types of Design

There are a number of different types of design performed by engineering design companies.

Type of Design

Most design work is done using CAD (Computer Aided Design) tools. These tools allow for modeling, simulation, 3D scanning, machine tool integration and a variety of other tasks that would normally require separate operators or departments to handle.

Types of Services

Within each category of design, these service companies may provide a number of different services.

  • Certification documentation
  • Load analysis
  • Manufacturing drawings
  • Manufacturing support
  • Part and material specification
  • Product manuals


Location can be an important factor when selecting a design service company. Some applications may require collaboration of personnel or materials, making local companies much more desirable and convenient. There may also be complications when dealing with companies overseas or from other countries.
