Recently, ESTUN's heavy-payload series of industrial robots successfully achieved the MTBF (Mean Time Between Failures) 120,000 hours certification with zero-failure performance, marking that ESTUN robots have reached the top industry level in stability, reliability, and durability.

In high-end manufacturing, MTBF is a core indicator for measuring the reliability of industrial equipment, directly reflecting the product's "anti-aging" capability and stable output under extreme operating conditions.

The 120,000-hour MTBF certification (365*24*13 years = 113,880 hours) demonstrates that ESTUN has joined the global peak camp of industrial reliability. It signifies a historic leap for domestic industrial robots from followers to leaders and symbolizes the core strength of Chinese intelligent manufacturing reaching world-class standards.

Core Highlights of the Heavy-Payload Series Robots

The ESTUN heavy-payload series robots that passed the MTBF certification adopt an innovative serial structure and modular design, laying the foundation for the derivation of multiple models.

Based on the new-generation JUMP trajectory transition algorithm, model adaptive acceleration and deceleration, optimized program scanning speed, and communication interaction efficiency, ESTUN heavy-payload robots comprehensively improve the operating cycle time by 15%, making motion transitions smoother and significantly reducing energy consumption, achieving dual optimization of performance and efficiency.

Furthermore, the wrist of the heavy-payload series robots adopts a fully sealed, fully geared dual-support structure, achieving IP67 protection rating. The main body has an IP54 rating (optionally IP65), adapting to more harsh environments.

Additionally, for the four major processes in the automotive industry—stamping, welding, gluing, and final assembly—the heavy-payload series robots can be expansively equipped with corresponding application software packages for stamping, spot welding, gluing, handling, SPR (Self-Piercing Rivets), and grinding/deburring.

Application Examples of Heavy-Payload Series Robots

Leveraging core features such as innovative modular architecture, high rigidity and low vibration structure, extended range of motion, and excellent protection rating, the ESTUN heavy-payload series robots provide efficient, reliable, and highly adaptable intelligent solutions for demanding application scenarios under complex working conditions like lithium battery manufacturing, automotive spot welding, automotive parts grinding, and die-casting part extraction.

The dedicated spot welding robot ER220-2700 meets the requirements of efficient, highly stable, and intelligent spot welding scenarios for auto bodies. It features load online identification, self-learning vibration suppression, and scenario-adaptive debugging. With precise pressure control, pressure error can be controlled within ±2%.

ESTUN offers two down-reach high-protection robots, models ER220-3100-DW and ER270-3100-DW, with wrist IP67 protection rating, main body IP65 protection rating, and special paint, meeting the application needs of the die-casting industry resistant to high temperatures, corrosion, and acids/alkalis.

High Reliability Supports the Rapid Development of Intelligent Manufacturing

As the first robot company in China to successfully obtain functional safety certification (compliant with EN13849 standards), ESTUN robots have received TÜV Rheinland CE certification, complying with ISO 10218-1, EN 13849 standards, and achieving Functional Safety Level: PL d, Cat. 3.

Furthermore, ESTUN has successfully obtained CR (China Robot Certification), cETLus (North American Safety Certification), and other mainstream global market access qualifications. It has also passed several industry-specific certifications such as cleanroom grade and explosion-proof, fully verifying the high reliability and stability of its products and supporting the rapid development of intelligent manufacturing in China.

With the 120,000-hour MTBF certification, ESTUN has set a new global benchmark for the reliability of industrial robots. This is not just a breakthrough in technical certification but also a concrete expression of ESTUN's vision to "become a respected international brand." In the future, ESTUN will continue to empower enterprises to upgrade their competitiveness and jointly advance towards new heights in intelligent manufacturing.
