Etched Fuel Injector Spray Plate is used for shaping gasoline and urea sprays at the injector tip with thin etched orifice plates, whose hole size, count and layout set droplet size and spray pattern. Injector OEM drawing is the reference cited for it on drawings, datasheets and purchase orders.
What Injector OEM drawing Means for Etched Fuel Injector Spray Plate
The dimensions in the table below are supplied to suit Injector OEM drawing. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

Specifying Etched Fuel Injector Spray Plate Beyond the Standard
- Hole count & diameter: 4–12 holes of 0.12–0.18 mm, matched to target flow.
- Spray angle: Set by hole position and wall taper on the etch exit face.
- Thickness & alloy: 0.1–0.15 mm SS316L or martensitic stainless for wear.
When Etched Fuel Injector Spray Plate Is Not the Right Choice
Not a filter screen — an inlet filter basket protects the injector upstream.
