The Problem We Solve

Your challenge

Speaker and mic openings are open doors for dust and water — and a mesh that chokes airflow kills acoustic output while one that is too open passes particles.

↓ Our solution
ROTADIE solution

Mesh laminates engineered per opening: woven PET/nylon meshes with controlled aperture and open-area, laminated with adhesive rings that seal without bridging the acoustic path.

Dust-Proof Meshes & Acoustic Grilles

Dust-Proof Meshes & Acoustic Grilles

Precision die-cut dust-proof woven meshes and acoustic grille laminates for speaker, microphone, receiver and pressure-vent openings — airflow matched, adhesive-backed, ready to place.

Key Features

The difference between a good mesh part and a bad one is measured in decibels and microns. ROTADIE laminates mesh into adhesive-ring assemblies that drop straight into your opening geometry — and we verify open-area against your acoustic simulation targets before cutting production.

Dust-Proof Meshes & Acoustic Grilles

  • Woven PET / nylon mesh, aperture 30 – 500 μm, Open-area ratios tuned for acoustic output vs. dust ingress, Adhesive ring lamination — seals edges without covering sound path, Water-repellent treatment options for IPX ratings, Die-cut to aperture geometry including micro-ovals and slots, Multi-layer laminates (mesh + foam + adhesive) for vent designs

Typical Applications

  • TWS earphone speaker & mic meshes, Smartphone receiver and speaker openings, Smart speaker grille assemblies, Hearing aid & medical acoustic vents, Automotive microphone arrays, Pressure-equalization vent membranes

How to Order

① Define the application — describe the device, the function of the part and the environment it works in.

② Send the drawing — DXF / PDF / STEP, or a dimensioned sketch with tolerances marked.

③ Confirm quantities — prototype quantity and estimated annual volume.

④ Review the proposal — we reply with material options, unit price and tooling cost within 24 hours.

⑤ Sample & validate — typical parts sampled in 3–5 working days (quoted per drawing), then mass production after your approval.

FAQ

1. What information do you need to quote my die-cut part?
Three things: (1) a drawing — DXF, PDF or STEP, even a dimensioned sketch works; (2) the material requirement, or simply the application and environment so we can propose; (3) estimated annual quantity. Every drawing is reviewed by an engineer before quoting, and we return a material proposal, unit price and tooling cost within 24 hours.
2. How fast can I get samples?
Sampling lead time depends on part complexity and is quoted together with your quotation. Typical parts are sampled in 3–5 working days after drawing confirmation; parts requiring special material sourcing or multi-layer lamination take longer. The lead time for your specific part is confirmed before you commit — no vague promises.
3. What is your minimum order quantity?
For prototype and validation runs we accept single-run quantities — you do not need to commit to mass production to test our quality. For mass production, MOQ depends on material and part size; small-quantity production runs are supported with per-unit pricing clearly shown.
4. Do I pay for tooling? Is it reusable?
Custom parts require a die tool, quoted as a one-time cost shown separately on the quotation. The tool stays reserved for your part — repeat orders have no tooling charge. For simple shapes we may use etched or laser cutting with lower or zero tooling cost.
5. How do you control quality?
Three stages: incoming material inspection (thickness, adhesive, certs), in-process inspection during die-cutting, and 100% outgoing inspection before packing. Dimension inspection reports and material certificates are supplied with shipment on request.
6. Which material brands do you convert?
We routinely convert 3M, Nitto Denko, tesa, PORON-class urethane foams, Kapton-class PI films and NOMEX-class aramid papers, plus qualified domestic equivalents when cost matters. All material declarations (RoHS / REACH) are supplied with shipment.
7. Can you ship internationally?
Yes. We ship worldwide from Shenzhen by international express (DHL/FedEx/UPS) for samples and small runs, and by air or sea freight for mass production. Export-standard packing with humidity protection is standard.
8. Can you help if I only know the application, not the exact material?
Yes — that is the normal case. Describe the device, the function the part must perform (seal, bond, shield, insulate, protect), the environment, and any constraints (thickness, temperature, approvals). Our engineer proposes 2–3 material options with trade-offs, and sampling validates the choice before you commit.
