III. Market Pain Points and Solutions

Currently, most companies producing high-end protective products have significant shortcomings in waterproof reliability testing. Conventional rain‑spray and shallow‑immersion equipment can only meet the lower IPX3 to IPX7 waterproof rating standards; they cannot simulate the sustained deep‑water pressure conditions required for IP68 or higher ratings. As a result, test results fail to meet the required standards and cannot be used for certification of premium products or for market acceptance. Furthermore, some rudimentary deep‑water testing devices lack pressure‑stabilization mechanisms, leading to large fluctuations in water pressure during testing, non‑standard operating conditions, substantial data deviations, and poor reproducibility—making it difficult to support product redesign and quality improvement.

Meanwhile, traditional pressure‑immersion equipment commonly suffers from poor chamber sealing, high‑pressure water leakage, structural deformation, turbid water quality, and clogged pipelines. These issues lead to a high equipment failure rate, cumbersome operation and maintenance, and frequent shutdowns that disrupt testing schedules. Moreover, the lack of robust safety safeguards poses significant risks during high‑pressure operations. In addition, many companies cannot independently perform IP68‑rated high‑level waterproof testing and must rely on external third‑party labs, resulting in long testing cycles, high costs, and low efficiency—seriously hindering product iteration and time‑to‑market.

The Four Core Pain Points of the Industry
1. Insufficient testing level; unable to meet the requirements of high-end products. Conventional waterproof equipment only supports medium- and low-grade waterproof testing and cannot perform IP68 deep-water constant-pressure immersion tests. It fails to meet operational requirements and cannot satisfy the protection certification and quality inspection standards for high-end products.
2. The hydraulic pressure conditions are unstable, rendering the test data unreliable. : Simple pressure vessels lack a precise pressure stabilization system; during testing, pressure fluctuates significantly, test conditions vary from run to run, and the data cannot be reproduced, making it unsuitable for product structural optimization or compliance verification.
3. Poor device stability; cumbersome and time-consuming operations and maintenance. : Older equipment has poor pressure resistance and sealing, leading to water leakage and deformation under high-pressure conditions. The water often becomes turbid, clogging the pipelines and requiring frequent cleaning and maintenance, which severely impacts batch testing efficiency.
4. External testing is costly and time-consuming. : Companies lack their own IP68 testing equipment and rely on third-party agencies, which not only incurs high testing costs but also results in long turnaround times, delaying new product development, corrective actions, and market launch schedules.

2. Accurate regulation of constant pressure ensures that test data is compliant and valid. The intelligent pressure-regulation system maintains a constant test pressure throughout the entire process, ensuring stable water pressure, immersion depth, and test duration. This standardizes test conditions, making the data traceable and reproducible, thereby providing accurate data to support improvements in product sealing designs and quality upgrades.
3. High-strength sealing structure reduces operational and maintenance burdens. : A thickened pressure-resistant chamber combined with multiple high-pressure sealing technologies eliminates high-pressure water leakage and chamber deformation; a closed-loop water circulation filtration system keeps the water clean, reduces pipeline clogging and equipment failures, ensures stable long-term operation, and simplifies routine maintenance.
4. Self-directed routine testing reduces costs and improves efficiency. After enterprises independently configure their equipment, they can conduct IP68 high-grade waterproof testing at any time without relying on third-party agencies, significantly shortening the testing cycle and reducing testing costs, thereby accelerating new product R&D iterations and time-to-market.
