- Introduction
In-depth interpretation of GB/T22350—2017 molded plywood standard
Background of standard formulation and analysis of technological evolution
The GB/T22350 series of standards has undergone many years of revision, reflecting the continuous progress of molded plywood manufacturing technology. The new version mainly makes important adjustments in the definition of terms, geometric deviation requirements and physical and chemical performance test methods to meet higher quality and diversified application requirements.

Case study: Application of multi-directional force-formed plywood
A furniture manufacturer uses the GB/T22350-2017 standard to accurately test the distortion and shape deviation to ensure that its products meet the quality requirements of high-end office furniture. They use a form and position deviation tester for strict testing and re-inspection of unqualified products, which significantly improves product quality.
Implementation suggestions
- During the procurement stage, choose testing equipment that meets the standard, such as an form and position deviation tester.
- Establish internal quality control processes and conduct inspections strictly according to the table parameters.
- Select appropriate classifications (unidirectional/multi-directional force, indoor/outdoor) for different application scenarios.
- Periodically conduct standard training for technical personnel to ensure correct understanding and implementation.
