What factors affect the open area ratio of ventilation mesh?

The open area ratio (typically 20%-70%) depends on: Material type (stainless steel, aluminum, etc.) Hole geometry (round, square, slot, gradient patterns) Mechanical strength requirements Application environment For chemical etching parts, the achievable open area is also related to material thickness, since etching precision and structural stability are thickness-dependent.

AI-Powered supplier vetting

SummaryThe supplier is a limited company focused on precision metal solutions, supported by laser cutting and CNC. It offers prototype development, small-batch customization, mass production, multiple metal materials, and surface treatments. Evidence indicates ODM services, recent new-product activity, OEM service for well-known brands, and flexible customization. Production information reports 100,000,000 precision etched metal parts, while the manufacturing plant covers 150.0 m². Quality-control evidence is incomplete: test equipment is stated as 0, and quality assurance and traceability statuses are unknown. The supplier has one R&D engineer and 11–20 quality-control staff. It maintains an overseas warehouse and accepts several trade and payment terms, with stated lead times within 15 working days in both peak and off-season periods. Service-management procedures are weak or undocumented, including complaint handling and corrective/preventive actions. No certification information or specific customer cases is...

Supplier typeThe supplier is a limited company providing integrated precision metal manufacturing, including laser cutting, CNC-supported solutions, prototype development, small-batch customization, and mass production. Its listed materials and finishes indicate a metal parts manufacturer rather than a purely trading or service-only company.

After-Sales capabilityOne R&D engineer is responsible for technical support for after-sales service, and the supplier has an overseas warehouse. However, the supplier reports no written procedures or records for complaint handling and corrective/preventive actions, so formal after-sales management appears insufficiently documented.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and has one R&D engineer responsible for customer requirement confirmation, technical support, and new product development. However, it has no available SDK, so the evidence supports product-development capability but not broader development-platform capability.

Production capacityThe supplier reports 100,000,000 precision etched metal parts, supports prototype, small-batch, and mass production, and uses materials including stainless steel, copper, brass, aluminum, nickel, and beryllium copper. Its 150.0 m² plant and stated production information support manufacturing capability, although quality-control test equipment is reported as 0 in another slice.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, together with ODM services. It also supports varied materials, coatings, plating, and other customized surface finishes, providing strong direct evidence of customization capability.

Client casesThe supplier states that it provides OEM services for well-known brands, which is evidence of at least one type of customer engagement. No brand names, project details, product examples, or verifiable case descriptions are provided, limiting the depth of customer-case evidence.

Product Q&A

Q:What is the minimum hole size and typical open area ratio for ventilation mesh?

We can manufacture ventilation meshes with the following capabilities: Square hole (etched or perforated): minimum size: 0.10 mm Round hole: depending on material and thickness, we can achieve sub-0.10 mm features (<0.10 mm in certain thin materials and optimized processes) Typical open area ratio: 20%-70% Higher or lower open area ratios are available depending on airflow, strength, and structural requirements.

Q:What materials are available for protective ventilation screens?

We offer a wide range of materials depending on application requirements, including: Stainless steel (SUS304, SUS316) Aluminum alloys Brass and copper alloys Galvanized steel (for cost-sensitive applications) Material selection can be optimized based on strength, corrosion resistance, and cost targets.

Q:What is the typical thickness range for ventilation mesh parts?

Our standard thickness range is 0.05 mm to 2.0 mm, depending on material and application. For most appliance ventilation covers, the typical range is 0.1 mm to 1.0 mm.

Q:What surface finishing options are available?

We provide multiple surface treatment options, including: Deburring (standard for all parts) Polishing (matte or mirror finish) Black electrocoating (Black e-coating for corrosion resistance) Black spray coating / painting Passivation for stainless steel Anti-fingerprint coatings (for visible panels)

Q:Can you ensure burr-free and safe edges for protective screens?

Yes. Chemical etching naturally produces burr-free edges, so ventilation meshes made by etching are inherently smooth and clean. For parts produced by other processes (such as laser cutting or stamping), we apply additional deburring and surface finishing to ensure: No sharp edges Safe handling Clean appearance No interference with airflow or assembly.
