QC Profile
Our Certifications & Patented Technologies
ISO 9001:2015 Quality Management System Certification

Our ISO 9001:2015 certification (Certificate No. 00125Q32720R0M/3502, valid until April 26, 2028, issued by CQC, an IAF/CNAS-accredited body) is our commitment to consistent, reliable quality for every order. This internationally recognized system governs every stage of our manufacturing process, ensuring your membrane switches, capacitive touch films, and custom control panels meet strict quality standards, no matter the order size.

Our ISO-compliant quality control process includes:

  1. Incoming Quality Control (IQC): All raw materials (PET/PC films, conductive inks, adhesives) undergo rigorous testing before production to eliminate defects at the source.
  2. In-Process Quality Checks: Every production step—from screen printing and lamination to CNC cutting and assembly—includes mandatory inspections with standardized SOPs to ensure batch-to-batch consistency.
  3. Final Product Verification: Before delivery, every product undergoes performance testing (durability, electrical function, environmental resistance) to confirm compliance with specifications.
  4. Continuous Improvement: Regular internal audits and process reviews refine our system, supported by our R&D team’s expertise.

Beyond standardized quality control, our in-house innovation capabilities are backed by two core invention patents that address key industry challenges, enhancing the performance and reliability of our products:

Anti-Static Membrane Switch and Its Manufacturing Method (Patent No. ZL 201910844959.6)

This patented technology solves static interference issues common in electronic applications, significantly improving the stability, durability, and operational reliability of membrane switches. The anti-static design prevents electrostatic discharge (ESD) damage, making our switches ideal for sensitive electronic devices and industrial environments where consistent performance is critical.

Anti-Fingerprint Surface Treatment Process for Touch Panels (Patent No. ZL 201910844960.9)

Our patented anti-fingerprint treatment creates a durable, low-friction surface that repels fingerprints, oil, and smudges. This ensures clear visibility, smooth touch operation, and long-lasting appearance even with frequent use, while also enhancing scratch resistance for touch panels in consumer electronics, home appliances, and smart devices.

These certifications and patents reflect our dual commitment to quality consistency and technological innovation. Whether you need standard membrane switches or custom touch panels, our ISO-compliant processes and patented technologies ensure products that meet global quality expectations, reduce your risk of defects, and deliver reliable performance for your applications.

National High-Tech Enterprise Certification

Our National High-Tech Enterprise certification (Certificate No. GR202335100045, issued in November 2023, valid for three years by Chinese government authorities including the Xiamen Science and Technology Bureau) is a formal recognition of our commitment to innovation, R&D, and advanced manufacturing. This prestigious qualification reflects our consistent investment in cutting-edge technologies and design capabilities, ensuring we can deliver innovative, high-performance solutions for your membrane switches, capacitive touch films, and smart home glass touch panels.
