Customer Background

Shenzhen LDROBOT Robotics Co., Ltd. (referred to as "LDROBOT") is a high-tech enterprise with the mission of "building the infrastructure of the intelligent machine era". It focuses on the research and development of robot motion perception technology and has 405 core projects and more than 200 inventions. Its products cover laser radar, 3D depth camera and robot control system, and are widely used in industrial AGV, medical disinfection and sterilization robots, logistics and warehousing and other fields. In 2025, Ledong Robotics will accelerate its IPO in the Hong Kong stock market and put forward higher requirements for product environmental adaptability testing. The stability of the sensor in the full temperature range of -40 ℃ to+150 ℃ needs to be verified through temperature and humidity simulation.

Collaboration background and demand upgrade

Since the purchase of the AP-HX-225D3 test chamber from Aipai Technology in 2022, Ledong Robot has highly recognized the performance of the equipment. In 2025, we will purchase the AP-HX-1000C6 from Aipei Technology. With the development of its new generation of high-precision sensors, the existing equipment is no longer able to meet the requirements in terms of temperature and humidity alternating rate, data traceability, and multi scenario compatibility. Specific pain points include:

Insufficient testing efficiency: A single temperature and humidity cycle test takes 72 hours, which restricts the iteration speed of new products;

Data accuracy deviation: Traditional equipment humidity fluctuates by ± 5% RH, resulting in a sensor performance data deviation rate of over 12%;

Scenario coverage limitations: It is necessary to simulate composite scenarios such as "high temperature and high humidity → low temperature and low humidity → rapid temperature changes", but existing equipment only supports single program settings.

Selection process and technical benchmarking

The Ledong Robot Technology Team spent 3 months comparing equipment from 6 domestic and foreign suppliers, and finally selected the Aipei Technology AP-HX-408C 408 liter constant temperature and humidity test chamber. The core advantages are as follows:

Full temperature coverage and precise control

Temperature range: -40 ℃ to+150 ℃, meeting the standard MIL-STD-810G;

Humidity uniformity: Adopting evaporator coil dew point temperature laminar contact dehumidification technology, humidity fluctuation is ≤± 2% RH, which is 60% higher than traditional equipment;

Temperature change rate: Under no-load conditions, the heating rate reaches 3 ℃/min and the cooling rate is 1 ℃/min. It supports the testing process of "85 ℃/85% RH continuous for 168 hours → -40 ℃ continuous for 24 hours".

Intelligence and Scalability

Controller: Equipped with a 7-inch touch programmable controller (AP-900 intelligent type), supporting 120 programs and 100 complex test designs per group, and can generate real-time test reports that comply with ISO 17025 standards;

Data interface: RS232/RS485 interface and USB drive export function, achieving seamless integration with LIMS system;

Remote monitoring: optional LAN module, supports PC remote control, reduces manual intervention.

Energy efficiency and reliability

Refrigeration system: equipped with French Taikang fully enclosed compressor and Japanese Hitachi spare compressor, using American DuPont R404A environmentally friendly refrigerant, energy consumption is reduced by 18% compared to imported brands;

Safety mechanism: equipped with six layers of protection including compressor high voltage protection, over temperature alarm, and leakage protection to ensure 24-hour stable operation;

Material and process: The inner box is made of 304 stainless steel material, combined with a polyurethane hard foam insulation layer, with temperature fluctuations of only ± 0.5 ℃ in a low temperature environment of -40 ℃.

Delivery and Service Assurance

Aipei Technology relies on the flexible manufacturing capabilities of its Dongguan production base to complete equipment production and debugging within 15 working days after the contract is signed, which is 40% shorter than the industry average cycle time. After delivery, a professional team will complete installation and training within 24 hours and provide the following services:

Warranty commitment: 365 day complete machine warranty, extended warranty period for core components (compressor, controller) to 2 years;

Response mechanism: 12 after-sales service outlets across the country promise to respond within 4 hours and arrive on-site within 24 hours;

Technical upgrade: Regularly push software update packages to support device function expansion and synchronization with industry standards.

Customer reviews

The R&D Director of Ledong Robotics said, "Aipei Technology not only provides a device, but also builds a full chain testing platform covering R&D, production, and quality inspection. Its fast response technical support and localized service network are the key factors for us to choose long-term cooperation

Industry Insights

This case reflects two major trends:

Domestic substitution acceleration: Local enterprises such as Aipei Technology have made breakthroughs in core technologies, branding in key indicators such as accuracy and stability, and the price is only 60% of imported equipment;

Deepening Service Ecology: From equipment customization, rapid delivery to full lifecycle maintenance, the technical response speed and service closed-loop capability of suppliers are becoming the core considerations for customer decision-making.

The deep cooperation between Aipei Technology and Ledong Robot not only helps China's intelligent perception technology break through environmental limitations, but also promotes the robot industry to move towards higher reliability standards with an integrated solution of "hardware+service".
