Deep drawing
How is leak tightness achieved in a deep drawn housing?
Answer
Solenoid Valve Housing: How Deep Drawing Removes The Weld Seam A deep drawn solenoid valve housing is seamless: how the weld seam disappears, what the draw ratio allows, and when a welded shell is still right. A solenoid valve housing that is machined from tube or fabricated from welded sheet starts life with a seam. The difference shows up in the leak test, in how uniform the wall is around the circumference, and in how much secondary work the part needs before it can be assembled. This guide explains how the seam is eliminated, what drawing can and cannot do, and how to write the requirement so a supplier can quote it.

- Leak-Tight Deep Drawn Housings: What Decides It | BalfordA drawn housing is leak-tight when the wall has no through-thickness defect and no seam, and when the surfaces that seal against an O-ring, a gasket or a mating part are sound. Unlike a housing welded up from tube and end caps, a deep drawn housing is one piece of metal, so there is no weld to leak,...

- Deep Drawn Solenoid Valve Housing Stock Parts | BalfordSolenoid valve housings are made by deep drawing rather than welding or casting: a flat blank is drawn into a cup and then redrawn or ironed until the wall is thin and straight enough for the coil, which is what gives a seamless housing with no weld seam to leak or to disturb the magnetic circuit.

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
