Polymer Filtration Plates

Laser micro-drilled metal filtration plates for plastics recycling and polymer processing, commonly described in the market as laser filter screens. We review suitable component geometry against the machine configuration, process conditions and filtration requirements.

80–400 µm Nominal aperture range; suitability depends on component geometry and application.

Final compatibility is confirmed against the machine model, existing component, drawing or physical sample.

Brand names are compatibility references only. Unless explicitly stated otherwise, EMC parts are not original or OEM parts from the named manufacturers; no manufacturer approval or commercial affiliation is implied. Final compatibility is confirmed against the machine model, existing component, technical drawing or sample.

Component definition

Component geometry and configuration

The component is defined through nominal aperture, micro-hole geometry, active filtration area, material and machine interface.

Filtration Geometry

Nominal Aperture
The nominal aperture range is 80–400 µm. Final aperture selection depends on component geometry and application requirements.
Micro-hole geometry
Inlet- and outlet-face geometry, including taper where required, is defined against the existing component and flow direction.
Hole Pitch & Pattern
Centre spacing and straight or staggered patterns are defined to suit the component geometry.
Filtration Surface
The micro-perforation pattern is reviewed together with the area exposed to process flow and the open-area ratio where required.

Micro-hole section and key geometric variables

We verify inlet and outlet geometry, aperture dimensions and taper against the existing component. Flow direction and the system interface are considered in the same review; the schematic shows one possible geometry.

Material & Thickness
Material and nominal thickness are reviewed against the existing component or drawing.
Machine Interface
Centre, perimeter, mounting and indexing features are matched to the existing equipment.

Plate Geometry & System Interface

Full component geometry is defined through the active filtration surface and the centre, perimeter and supporting regions that interface with the existing equipment.

Technical review

Let’s discuss your filtration requirements

A machine or system reference may be enough to begin an initial review. We’ll identify any additional technical information with you.

Information you can share for the initial review

You can start with the information you already have; not every item below needs to be ready.

Machine / System Reference

Machine make/model or, where known, the existing part reference.

Application / Filtration Requirement

Process context, target filtration level or the feature that needs to change.

Existing Part Information

Existing component, clear photographs and known critical dimensions where available.

Drawing / Sample — If Available

An existing technical drawing or physical sample can support the review.

A drawing or sample is not required to begin.
