Design for Machining Fiberglass and Composites
Machining Composites poses unique challenges for manufacturing and design engineering to meet an end items requirements. Composites are group of materials that include Random Fiber, Prepreg, intermediate Layers and Vacuum Bag construction.
Design for Thermoforming Vacuum
The process of evacuating air from the sealed space between the hot sheet and the mold, thus allowing atmospheric pressure (14.7 p.s.i .) to force the sheet to conform with the contour of the mold.
Projection Welding Review and Design Considerations
Projection welding is an electric resistance welding process that produces welds by the heat obtained from the resistance to the flow of the welding current. The resulting welds are localized at predetermined points by projections, embossments, or intersections
Cost of Welding Review Equation and Calculator
Welding costs can be estimated using one of three basic approaches : Cost per unit. Cost per length. Cost per weight.
Die Casting Dimensional Design and Tolerances
High pressure die casting tooling and component design and dimensional tolerances.
