How do you guarantee product quality?

We strictly follow full-process QC (IQC, IPQC, FQC). Equipped with advanced measuring tools such as 2D optical projectors, micrometers, height gauges, and pin gauges, we perform 100% inspection on all critical dimensions to ensure precise fit and tolerance.

Do you only make earphone shells, or can you take orders from other industries?

Absolutely. Our versatile CNC equipment is highly adaptable. While we specialize in Hi-Fi audio hardware, we also extensively undertake custom non-standard machining for 3C electronics, automotive parts, precision instruments, and medical devices.

What are your payment and shipping terms?

We accept T/T, PayPal, or Trade Assurance. The payment term is usually 30% deposit, and 70% balance before shipment. For shipping, small batches go via international express (DHL/FedEx/UPS), and large volumes by air or sea freight. We offer FOB, CIF, and EXW pricing terms.

AI-Powered supplier vetting

SummaryDongguan Wanxing Hardware Technology Co., Ltd. is a China-based limited company established in 2018, with 11 employees and three production lines. It supplies hardware and related metal, mold, aluminum, intelligent equipment, and automotive-part products, and reports domestic primary markets. The supplier demonstrates product-development capabilities, including an available SDK, private mold design, professional technical expertise, 3D software design, and sample-based customization. It reports procedures and records for corrective/preventive actions and customer complaints, but explicitly reports no quality assurance in quality-control processes. Financial records are indicated for recent years, but no financial results are provided. Export capability is a concern because the supplier reports no valid import/export license, despite a business scope that includes import and export subject to applicable requirements. Certification holdings, customer cases, and environmental or fire-drill status are not...

Supplier typeThe supplier is a China-based limited company established in 2018, operating as a combined research, development, production, sales, and processing business. Its stated scope covers hardware, metal products, intelligent equipment, molds, aluminum products, and automotive parts, while its primary offered product is hardware.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaint handling. However, the evidence does not describe response times, service coverage, staffing, or actual customer-service outcomes, so capability is supported only at the procedural level.

R&D capabilityThe supplier reports an available SDK, private mold design capability, professional technical-supplier status, and 3D software design services. Its business scope also includes research and development of hardware, intelligent equipment, and molds, providing explicit evidence of development capability.

Production capacityThe supplier operates three production lines and states that it performs research and development, production, sales, and processing across hardware and related products. It has 11 employees and reports an off-peak lead time within 15 working days, indicating an operating production base, although capacity volume and peak-season performance are not provided.

Customization capabilityThe supplier explicitly provides customization from samples, private mold design, and 3D software design services. Its stated scope includes molds and processing, which directly supports customized hardware development and manufacturing.

Product Q&A

Q:Are you a factory or a trading company?

We are a direct factory with our own CNC workshop and professional engineering team. We control everything from drawing evaluation, programming, processing, to quality inspection fully in-house.

Q:I don't have a drawing. Can you help me design it?

Of course! We provide ODM services. If you have a basic concept or sketch, our engineering team can handle structural design and 3D modeling, providing a full Design for Manufacturing (DFM) analysis.

Q:What drawing formats do you accept? What is your MOQ?

We accept 2D (PDF, DWG, DXF) and 3D (STEP, IGS, SolidWorks) formats. We have no strict MOQ. We support 1-piece prototyping as well as large-volume mass production orders.

Q:What is the lead time for prototyping and mass production?

Standard prototyping is usually completed within 5-7 working days (expedited service is available upon request). Mass production lead time depends on the specific quantity, generally 15-25 working days after order confirmation.

Q:What surface treatments do you offer? How do you ensure corrosion resistance?

We offer various surface treatments such as anodizing (natural/colored), sandblasting, wire drawing, high-gloss polishing, and electroplating. We are equipped with professional salt spray test chambers. All finished products undergo salt spray testing to guarantee excellent corrosion resistance of the surface finish in harsh environments.
