For over 70 years, AIPHONE has been a globally trusted leader in intercom manufacturing, maintaining the highest quality standards in the industry. Commanding over 50% of the domestic market share and leading the global market, AIPHONE's commitment to excellence has earned widespread recognition across the globe. The key to this success? Superior quality. Let's explore the secret behind AIPHONE's "unbreakable intercoms," made possible through our comprehensive quality control system that spans everything from product planning and design to manufacturing and after-sales service.
Since our founding in 1948, AIPHONE's commitment to quality has been anchored in our founder's guiding principle: "Take full responsibility for everything we produce, from beginning to end." This philosophy has been our cornerstone for over 70 years, driving us to ensure our products perform reliably throughout their entire lifecycle.
We don't just manufacture products; we strive to earn and maintain our customers' trust. In the 1960s, we revolutionized the industry with our "unbreakable intercom," establishing ourselves as the quality and durability leader among Japan's numerous intercom manufacturers. Our dedication to excellence has continued to grow, as evidenced by our ISO 9001 certification and two times of prestigious Deming Prizes - the highest global recognition for Total Quality Management (TQM).
Our quality philosophy extends far beyond durability. We maintain rigorous quality control at every stage: from customer-focused design prioritizing safety and security, through component selection and manufacturing, to post-installation maintenance. This unwavering commitment to quality has earned us widespread recognition both domestically and internationally. We've maintained over 50% market share in Japan for many years and achieved global market leadership with a 12.2% share (as of 2021).
In today's fiercely competitive global market, AIPHONE's exceptional quality continues to be our defining advantage, setting us distinctly apart from our competitors. This commitment to excellence has become our signature strength, earning us a unique position in the international marketplace.
AIPHONE's commitment to quality exemplifies the finest traditions of Japanese manufacturing. This isn't merely a corporate directive - it's woven into our company's DNA, where every employee actively contributes to quality improvement and embraces the pursuit of continuous refinement. This approach stems from Japan's deep-rooted manufacturing philosophy and the exacting quality standards of the Japanese market.
In Japan's housing industry, intercoms are considered long-term infrastructure rather than consumer electronics. Unlike household appliances that are replaced every few years, intercoms must maintain reliable functionality for extended periods. This understanding shapes AIPHONE's design philosophy - we engineer our products for exceptional longevity: 15 years for apartment building systems, 12 years for commercial, medical, and facility equipment, and 10 years for single-family home systems. To achieve such durability, our designs focus on long-term operational stability. Our components must not only comply with domestic and international standards - including ISO, JIS, UL, CSA, and the Electrical Appliance and Material Safety Law - but must also pass AIPHONE's own stringent testing criteria.
By consistently meeting the demanding requirements of the Japanese market, we've maintained our position as the domestic market leader while earning continued trust from customers worldwide.
At AIPHONE, we've established the AIPHONE Technical Standard (ATS), an extensive framework of over 600 design criteria developed specifically for products with a lifespan exceeding 10 years. These standards haven't remained static - they've evolved through rigorous analysis of customer feedback and incident reports from both domestic and international markets, ensuring we prevent recurring issues through continuous improvement.
For instance, when we encountered frequent speaker failures, we responded by implementing new structural standards for voice coil design and materials, accompanied by comprehensive quality testing protocols to verify compliance. This exemplifies our approach: as our products evolve, we continuously review and enhance our standards to meet emerging challenges.
Within the ATS framework, we've identified our "10 Safety Articles" - the most critical safety-related standards that form the cornerstone of our design philosophy. These articles establish crucial safety protocols, such as fail-safe designs that prevent smoke or fire even if a single component fails, and circuit protection systems that safely interrupt power in case of abnormal current flow. We've taken fire prevention particularly seriously, incorporating flame-resistant materials in our product casings. This unwavering focus on safety guides every aspect of our design process.
Rigorous component selection is a cornerstone of AIPHONE's quality philosophy. Our commitment to delivering products that maintain stable performance over many years drives our meticulous approach to choosing every part.
At AIPHONE, we select components based on a fundamental understanding: our intercoms operate continuously, 24 hours a day, 365 days a year. This demands parts that can withstand constant use while maintaining exceptional reliability.
AIPHONE's components don't just meet industry standards like ISO, JIS, UL, CSA, and Electrical Appliance and Material Safety Law - they exceed them. Every part and auxiliary material must pass AIPHONE's own rigorous durability testing, reflecting our uncompromising commitment to quality.
For outdoor equipment components, we conduct comprehensive environmental testing that goes beyond basic temperature and humidity trials. Our tests account for real-world conditions including UV exposure, dust infiltration, and corrosion resistance. Components are only approved after proving their reliability in actual operating conditions.
We take the same meticulous approach with auxiliary materials. For example, when soldering components with different thermal expansion coefficients, temperature fluctuations can potentially cause solder cracks due to varying expansion and contraction rates. To mitigate this risk, we manufacture prototype circuit boards and subject them to extensive heat shock testing - repeatedly exposing them to extreme temperature variations to verify their thermal resilience. We select only auxiliary materials that demonstrate exceptional performance under conditions even more demanding than real-world usage.
AIPHONE's standards transcend conventional compliance. Our selection criteria for both components and auxiliary materials reflect decades of expertise and technological innovation. This rigorous selection process ensures our products maintain stable operation for over a decade - the foundation of what has become known globally as "AIPHONE quality."
Beyond our rigorous component and material testing, AIPHONE conducts extensive additional testing to ensure our products perform reliably across all operating environments.
Our operational testing simulates real-world usage conditions with thoroughness. Take our button durability testing, for instance: we design for over 10 years of use, then subject the buttons to several times that number of actuations to verify their longevity. For new product development, we conduct large-scale system integration tests involving up to 1,000 interconnected units to verify system stability. These tests far exceed industry standards, reflecting our commitment to exceptional quality assurance.
This comprehensive testing approach enables us to create products that perform reliably even in challenging conditions. Behind every AIPHONE product's proven durability lies our meticulous attention to quality standards and controls at every level.
AIPHONE's reputation for superior quality is based on our comprehensive quality control system, spanning from component selection through manufacturing to final inspection. This isn't simply part of our process - it's the foundation of our product reliability. Our commitment is demonstrated through stringent component standards, electrostatic discharge (ESD) protection, and 100% inspection protocols.
Our factories in Thailand, Vietnam, and Japan operate under the AIPHONE Working Standard (AWS), a rigorous set of production guidelines that ensures consistent quality across all facilities.
Pivotal to these standards is our comprehensive ESD protection protocol, which is crucial for maintaining product integrity. Our manufacturing environments implement complete ESD protection systems through multiple safeguards. Personnel are required to wear conductive gloves and grounding straps while working with sensitive components. Each workstation is equipped with ionizers and conductive mats to prevent static buildup. Furthermore, all ESD protection equipment, including power outlets, undergoes regular inspection and maintenance to ensure optimal performance at all times.
AIPHONE maintains rigorous quality control through comprehensive inspection systems across our manufacturing processes.
In the circuit board assembly phase, every board undergoes automated inspection using specialized equipment: Solder Paste Inspection (SPI) verifies solder printing quality, while Automated Optical Inspection (AOI) examines component placement and soldering integrity. Each board must meet strict specifications before advancing. Following these inspections, boards undergo functional testing using specialized probe equipment to verify electrical performance. Only boards that pass these stringent tests move forward in the production process.
The assembled products then undergo thorough functional testing, where we verify proper operation of key video, audio, and operational features through powered testing of every unit. Our quality control system ensures thorough inspection from individual board testing through final product verification. Before shipment, each product undergoes a final quality check against all standards, and only units meeting every criterion leave our facilities.
This commitment to comprehensive quality control has earned AIPHONE international recognition, including two times of prestigious Deming Prizes. The Deming Prize, awarded only to organizations demonstrating exceptional total quality management across their entire operation, requires rigorous on-site auditing by the award committee. This honor represents achievement beyond mere compliance with standards - it recognizes an organization's genuine dedication to quality excellence throughout every aspect of its operations.
We maintain comprehensive quality control and support systems to ensure our customers can rely on their products with complete confidence long after purchase.
At AIPHONE, repair services continue even after a product line is discontinued. Understanding that our customers rely on our products for more than a decade, we maintain critical parts for approximately seven years after discontinuation, focusing on our most essential product lines. In the rare event of a significant product issue, our network of sales subsidiaries and authorized distributors provides on-site repairs and replacements, demonstrating our commitment to thorough after-sales service and earning our customers' trust.
For essential components that directly impact product safety and performance, such as power supply parts and fuses, we employ a centralized lot management system that tracks both finished products and individual parts. This comprehensive tracking system enables us to quickly identify and address any issues that may arise, pinpointing affected units for rapid and precise response. This robust infrastructure ensures we can continue providing our customers with the reliability and peace of mind they expect from AIPHONE.
