On November 12, 2025, the 26th China (Chengdu) International Gas Equipment, Technology and Application Exhibition grandly opened at the Chengdu Century City New International Convention and Exhibition Center. As a core component of the concurrently held 3rd China International Hydrogen Energy, Hydrogen Refueling Station and Fuel Cell Equipment Exhibition, this year's exhibition brought together over 200 leading companies from around the world, with an exhibition area exceeding 20,000 square meters. On the first day, Chongqing Chuke Intelligent Machinery Equipment Co., Ltd. (hereinafter referred to as "Chongqing Chuke Intelligent") became the focus with its globally debuted patented gas cylinder clamp
Laser Marking Machine, attracting numerous exhibitors and over ten industry leaders for on-site discussions and technical cooperation negotiations that continued until the exhibition closed.
Chongqing Chuke Intelligent showcased its Sino-foreign language laser
Marking Machine for gas cylinders, addressing the pain points of low accuracy and efficiency in marking the curved surfaces of high-pressure gas cylinders. It achieves three core technological breakthroughs:
1. Dynamic Curved Surface Compensation System: Integrating a laser rangefinder sensor and multi-axis linkage algorithm, it adjusts the beam focus point in real time, ensuring a marking depth error of ≤0.005mm on curved surfaces, overcoming the limitations of traditional equipment where "flat markings are easily deformed and curved surface markings are unclear."
2. Modular Quick-Change Fixture: Its patented adaptive clamping structure supports rapid switching between 12 types of standard gas cylinders, including oxygen cylinders, hydrogen cylinders, and liquefied gas tanks, within 30 seconds, covering compatibility with over 90% of industrial gas cylinder models.
3. Intrinsically Safe Explosion-Proof Design: The entire machine has passed Ex d IIB T4 explosion-proof certification and is equipped with an inert gas protection device, allowing direct operation in flammable and explosive gas filling workshops, filling a gap in the industry.
Certified by the Special Equipment Safety Inspection Center of the State Administration for Market Regulation, this equipment reduces the marking time per cylinder by 80% compared to traditional mechanical stamping, and the marking corrosion resistance reaches 10 years (SGS standard).
At the exhibition, CIMC Enric signed a purchase agreement for three dedicated gas cylinder marking machines and introduced Chuke Intelligent's system to achieve millisecond-level identification and automatic rework of marking defects. "This technology will reduce our annual gas cylinder repair rate from 2.1% to 0.3%," said the technical director of CIMC Enric.
"We are currently increasing the overall equipment efficiency (OEE) from 82% to 88%," the company's general manager revealed at a press conference. In 2026, a dedicated
Laser Welding Machine for hydrogen fuel cell stacks will be launched, and a joint research project with Chongqing University will be undertaken to develop ultrafast laser nanoscale marking technology.
"Chuke Intelligent's breakthrough proves that SMEs can also build technological barriers in niche markets," the exhibition secretary-general pointed out during a tour of the exhibition halls. According to statistics, the number of visitors on the first day exceeded 8,000, of which overseas buyers accounted for 15%. Companies from Pakistan, Saudi Arabia and other countries placed orders for prototypes on-site and held discussions on localized production.
