The stainless laser-drilled screen series pairs 120–800 µm holes with 1.5–2.0 mm plate for polymer-melt screening. Each configuration records inlet diameter, outlet diameter, plate thickness and flow direction. A straight passage has equal nominal end diameters; a tapered passage has separately dimensioned ends. Hole diameter is the geometric opening; separation performance is defined by the particle test and the sealed assembly.

The stainless laser-drilled screen series pairs 120–800 µm holes with 1.5–2.0 mm plate for polymer-melt screening. Each configuration records inlet diameter, outlet diameter, plate thickness and flow direction. A straight passage has equal nominal end diameters; a tapered passage has separately dimensioned ends. Hole diameter is the geometric opening; separation performance is defined by the particle test and the sealed assembly.
The outside diameter, active hole field and unperforated sealing ring share one centre datum. Specify pitch, solid bridges, locating holes and orientation marks on the same drawing. Keep fasteners and gasket compression within the solid land. A backing plate supports the active field while its passage pattern leaves the laser holes open. Mounting dimensions include the finished plate and any retaining rim.
Inspect hole diameter on the named working face, exit profile, pitch, blocked holes, residual recast, flatness and rim condition. Cleaning direction follows the marked passage profile and equipment flow path. Inspect the sealing face and support contact after cleaning so reassembly restores the same active field and edge seal.

The outside diameter, active hole field and unperforated sealing ring share one centre datum. Specify pitch, solid bridges, locating holes and orientation marks on the same drawing. Keep fasteners and gasket compression within the solid land. A backing plate supports the active field while its passage pattern leaves the laser holes open. Mounting dimensions include the finished plate and any retaining rim.
Inspect hole diameter on the named working face, exit profile, pitch, blocked holes, residual recast, flatness and rim condition. Cleaning direction follows the marked passage profile and equipment flow path. Inspect the sealing face and support contact after cleaning so reassembly restores the same active field and edge seal.
Specify inlet and outlet diameters, thickness and flow direction together. This identifies the narrowest passage and the two faces used for measurement.
The active diameter bounds the perforated field. Solid rims, locating features and support contact areas are separate from this field; the hole pattern determines its open-area fraction.
