High Acoustic Transparency
The speaker dust net is engineered with precision micro-porous fabric that allows air and sound to pass through effortlessly while blocking dust and small particles. This design maintains excellent sound quality and protects internal components, making it ideal for speaker, microphone, and earpiece openings in smartphones and other devices.
Reliable Dust and Moisture Protection
Using advanced acoustic dustproof mesh materials, ODT ensures that your product remains protected from fine particles and humidity. The mesh surface resists water droplets while maintaining sound performance. This dual-function protection improves device longevity, especially for portable electronics used in everyday environments.
Precision Die-Cutting and Adhesion
Each Acoustic Mesh Sticker is produced with automated die-cutting systems that maintain dimensional accuracy within ±0.01 mm. Adhesive performance is tested with peel and retention tests to ensure consistent bonding over time. The precise shape and clean edges make it suitable for high-end applications where tolerance and alignment matter.
Multi-Layer Material Composition
As shown in the product structure, the adhesive dustproof mesh typically consists of multiple layers — including a top liner with pull-tab, acoustic fabric mesh, adhesive layers, foam spacer, and a bottom liner. Each layer serves a specific purpose: the mesh ensures breathability, the foam provides cushioning and sealing, and the adhesives secure the assembly to the housing. This multi-layer construction is laminated automatically to maintain perfect alignment and consistent thickness across the roll.
Versatile Material Options
ODT provides a wide range of material combinations to meet different acoustic and environmental requirements. The mesh can be made from nylon, PET, or PU fabrics; foam materials such as EVA, PORON, or EPDM can be added for sealing and vibration control; and adhesives include acrylic or silicone types for various temperature and bonding needs. Liner materials can be PET film or release paper, allowing smooth processing and automated assembly.
Our Die-Cutting Equipment
ODT operates a modern die-cutting production line located in a 1000-class cleanroom, ensuring that every product meets the highest cleanliness and precision standards required for acoustic and optical components.
Our Automatic Roll-to-Roll Laminating Machine enables seamless bonding between mesh and adhesive layers, guaranteeing uniform lamination without air bubbles or wrinkles. This equipment is ideal for high-volume production while maintaining consistent adhesive accuracy across the entire roll.
The Automatic Waste Removal Machine enhances production efficiency by automatically removing excess materials after cutting. This system not only improves throughput but also minimizes contamination risks and manual handling errors. Finally, our Precision Die-Cutting Machines form the core of our production line.
They support both flatbed and rotary die-cutting, enabling the creation of highly complex mesh shapes and gasket structures with tolerances as tight as ±0.01mm. These machines ensure stable, repeatable accuracy even for ultra-thin materials used in acoustic mesh filters or adhesive dustproof stickers.
Our Die-Cutting Quality Control
ODT implements a comprehensive quality control process, combining advanced instruments and strict in-process inspection to ensure the highest quality for every acoustic mesh film we produce.
Our 2.5D Measurement System verifies the dimensional accuracy of each die-cut part, while the CCD and binocular microscopes detect even the smallest edge defects or fiber irregularities. The Dust Particle Counter continuously monitors cleanroom air quality to prevent contamination during manufacturing.
In addition, we perform peel strength and tape retention tests to confirm adhesive durability over time. The Constant Temperature and Humidity Chamber simulates extreme environmental conditions to verify that the product maintains stability in different climates. All inspection data are digitally recorded for traceability through our MES system, ensuring consistent product quality for every batch.
Our Inspection Team
Our professional inspection team operates entirely within the 1000-class cleanroom. Each member is trained to perform critical visual, dimensional, and functional checks on every batch of acoustic mesh covers before shipment.
Final inspections include acoustic permeability tests, adhesive strength verification, and visual inspection under high-magnification microscopes. This zero-defect commitment ensures that every piece leaving the facility meets ODT’s strict standards for cleanliness, precision, and performance.
Our Mold Management
ODT’s in-house mold department plays a key role in the precision of our die-cutting operations. Using advanced CAD software, CNC machining, and laser cutting systems, the team designs and fabricates molds specifically for complex products such as speaker dustproof mesh stickers and acoustic mesh gaskets.
Each mold is cataloged and maintained through a structured lifecycle management system, including periodic inspection, calibration, and refurbishment. This ensures every mold consistently produces high-accuracy cuts and supports rapid customization for new customer designs.
Our Product Cases
Acoustic Mesh / Dustproof Gasket:
Used in smartphones, tablets, and wearable devices to protect speakers and microphones. It provides excellent airflow, prevents dust intrusion, and maintains clear sound quality. The mesh is produced with high precision die-cutting and tested for acoustic transparency and adhesive performance.
Camera Foam Gasket:
Applied around smartphone camera modules to block dust and prevent internal light leakage. Made from high-density foam, it ensures a clean optical path and enhances image clarity. The product undergoes adhesion and environmental durability tests to ensure reliability in high-end camera assemblies.
PET/PC Protective Sheet:
Serves as an insulation and protection layer for screens, flexible printed circuits (FPCs), and display panels. It features excellent transparency, scratch resistance, and thermal stability. Every piece is measured with a 2.5D instrument and checked under a CCD microscope to guarantee surface perfection and consistent thickness.
An dust filter mesh sticker is a thin, breathable fabric that lets sound waves pass through while blocking dust and water droplets. It works by balancing pore size and air permeability, ensuring clear audio and physical protection at the same time.
No. The waterproof acoustic mesh is designed with high acoustic transparency (over 95% sound transmission). It minimizes distortion and maintains the natural sound profile of speakers and microphones.
ODT’s advantage lies in its precision die-cutting process, cleanroom production, and strict inspection standards. Our Adhesive Acoustic Mesh maintains consistent dimensions and adhesion, ensuring stable performance even under temperature or humidity variations.
Yes, ODT provides both standard and Waterproof Acoustic Mesh versions. The waterproof model includes a hydrophobic coating that prevents liquid ingress without affecting airflow.
