Built Around Your Testing Needs
Solution Overview
KINGDA provides automated door opening and closing durability testing solutions for refrigerators, washing machines and kitchen appliances. Our systems simulate repeated door operation to evaluate the durability of doors, hinges, handles, seals and related components during product development and mass production.
With programmable motion control, adjustable fixtures, automatic data logging and multi-station configurations, the equipment can be adapted to different appliance models and testing requirements.
The Challenge
Industry Challenges
- 01
Inconsistent Manual Testing
Manual testing is time-consuming, operator-dependent and difficult to scale for high-volume durability testing.
- 02
Limited Test Conditions
Basic testing equipment may not reproduce real-world door operation, making it difficult to identify potential issues with hinges, seals and moving components.
- 03
Limited Equipment Flexibility
Equipment designed for only a few appliance models can increase investment, floor-space requirements and operating costs.
- 04
Insufficient Data Traceability
Without automatic data recording and reporting, manufacturers may face difficulties tracking test results and supporting quality audits or certification documentation.
From Control to Traceability
Our Testing Solution
- 01
Servo-Controlled Durability Testing
Precise servo-driven motion enables repeatable door opening and closing cycles while reducing operator-related variation.
- 02
Multi-Condition Testing
The system can be configured to evaluate the durability of appliance doors, door hinges, door handles, sealing components, door locking mechanisms and related moving structures.
- 03
Adjustable Fixtures
Flexible fixtures and programmable parameters allow one system to support different appliance models and door configurations.
- 04
Automatic Data Recording
Test cycles, operating parameters and abnormal conditions can be recorded automatically. Data export and alarm functions support quality traceability and test analysis.
- 05
Long-Duration and Batch Testing
The equipment is designed for repeated, long-duration testing in appliance R&D laboratories and manufacturing quality-control environments.

Applications
The NB-IoT/4G IoT Water Meter is widely suitable for billing in urban water supply networks, residential water metering, commercial and industrial water monitoring, and upgrades to older residential communities. With deep NB-IoT network coverage, low power consumption and extensive connectivity, it is particularly suited to remote metering installations with dispersed locations, complex electromagnetic environments and limited power availability.
The product requires no wiring or concentrator and connects directly to the operator’s IoT platform. With low deployment costs and short installation times, it enables rapid, large-scale deployment of remote water meter reading and data management.
