Friends! Let's talk about filter screens today. Whether you're in the business of making air purifiers or industrial filtration equipment, you must have had these troubles: too single mesh hole type, insufficient hole-opening precision, and many burrs on the edges... Don't worry, get to know the laser-cut hollow filter screen!
1. What types of filter screens can be made by laser cutting?
Laser cutting can be said to be a "magic tool" for filter screen processing. Basically, it can make various hole types:
Round holes: The most common, with uniform filtration
Oval holes: Suitable for special fluid directions
Diamond holes/hexagonal holes: High strength and good filtration efficiency
Slotted holes: High-precision filtration
Irregular holes/pattern holes: Customized design
Gradual holes: The hole diameter gradually changes from the outside to the inside
No matter what shape you need, just send the CAD drawing and we can cut it!
2. In which fields are they used?
The application scope of laser-cut filter screens is quite wide:
Air purification field:
Air purifier filters
Air conditioner outlet filters
Industrial dust removal equipment
Primary filtration of fresh air systems
Liquid filtration industry:
Oil filters
Water treatment filter screens
Chemical liquid filtration
Food and beverage filtration
Automobile industry:
Automobile air conditioning filters
Engine intake filtration
On-board air purifiers
Electronic equipment:
Radiator filter screens
Dust covers
Ventilation holes of instruments and meters
3. Why do people like to use laser cutting for filter screens?
To put it simply, both traditional stamping and wire mesh weaving have quite a few drawbacks:
| Traditional processes | Advantages of laser cutting |
|---|---|
| Single hole shape | Free design of holes in any shape |
| Low precision | Precision up to ±0.05mm |
| Edge burrs | Smooth cut without burrs |
| Expensive molds | No need for mold opening, direct cutting with CAD |
| Difficult for small batches | Orders starting from 1 piece, flexible and fast |
Moreover, laser cutting is a non-contact processing method, and the material will not be deformed under pressure, which is especially suitable for thin plate filter screens.
4. What materials can be processed?
We can cut all the common filter screen materials:
Stainless steel mesh: 304/316/316L, corrosion-resistant and high-strength
Galvanized mesh: Low cost and decent rust prevention
Aluminum alloy mesh: Lightweight and good heat dissipation
Copper mesh: Good electrical conductivity, used in special environments
Plastic mesh: PP/PET/Nylon
Titanium mesh: High temperature-resistant and corrosion-resistant
We can process materials with a thickness ranging from 0.1mm to 3mm!
5. Common specification parameters
| Parameters | Range |
|---|---|
| Minimum hole diameter | 0.1mm |
| Hole pitch precision | ±0.05mm |
| Processing width | 1500×3000mm |
| Processable thickness | 0.1mm～3mm |
| Minimum line width | 0.1mm |
We can make single-layer meshes and multi-layer composite meshes according to customer requirements, and can also achieve the design of different hole densities in different areas!
6. What are the unique skills of laser-cut filter screens?
After years of making filter screens, we have summarized the following experiences:
✅ Precise aperture: The smallest hole that can be cut is 0.1mm, with an error control of ±0.05mm.
✅ Diverse hole shapes: Round holes, square holes, diamonds, and irregular shapes can be cut as you like.
✅ Smooth edges: The cut has no burrs and does not require secondary grinding.
✅ High opening rate: Compared with traditional stamping, a higher opening rate can be achieved.
✅ Flexible design: Holes of different densities and shapes can be made on the same plate.
✅ Small batches can also be made: Orders start from 1 piece, suitable for sampling and customization.
7. Customer case sharing

8. Frequently asked questions
Q: Can you cut filter screen holes that are too small?
A: Yes! The smallest hole we can cut is 0.1mm, but it also depends on the material thickness. The thicker the material and the smaller the hole, the more difficult it is to cut.
Q: What is the price for large quantities?
A: The price is definitely more favorable for large quantities! It specifically depends on the material, thickness, aperture, and quantity. Welcome to inquire with your drawings.
Q: How long is the delivery time?
A: Samples can be produced within 24 hours, and it takes 3 - 5 days for large quantities. It can be done within 48 hours for urgent orders!
