Although modern mechanical engineering relies extensively on 3D CAD programs for design, engineering drawings still rule the day for manufacturing and documentation control. Even when a 3D file is used directly by a manufacturer, the drawing is still used to relay important information such as material types, part markings, tolerances, and more.
Everything begins with the 3D model that represents the part we need to produce. We do not typically create a drawing for the part until there is a need. In most cases its because we need to have the part manufactured.
Mechanical Drafting Services
Here at Zalaco, we can provide drawings for any type of part that you need to have produced. Whether its re-creating legacy drawings from old documents, reverse engineering existing components, detailing a partially complete design, or starting from a blank piece of paper – we can help.
Detailed Fabrication Drawings
This is the core of mechanical drafting. The goal is to clearly communicate what we need to a potential supplier. Good engineering drawings help you get quotes back faster. They also ensure that your supplier understands exactly what you need and no one gets a surprise down the road. These drawings include all of the information necessary to manufacture the part – dimensions, tolerances, materials, finishes, and any other appropriate information.
This includes drawing for machined parts, molded parts, sheet metal parts, formed parts, and castings.
