To ensure dimensional accuracy, structural stability, and consistent bonding quality of cleanroom panels, our company implements strict process control throughout the entire handmade panel production process. Key control points are as follows:
Control of Plate Cutting Dimensions:
Before production, all steel coils released from the warehouse are verified to ensure consistency with the production order, including steel mill name, furnace batch number, thickness, and size specifications.
Prior to mass production, a first-piece self-inspection is conducted. Inspection items include:
Overall dimensions
Diagonal accuracy
Edge quality and cutting burrs
Only after the first piece passes inspection is mass production allowed to proceed. During production, continuous in-process inspections and random spot checks are implemented. If any nonconforming products are identified, corrective action is taken immediately, and production is adjusted or suspended when necessary. Defective products are strictly prevented from entering the next process.
2. Control of Structural Frame (Keel) Cutting Dimensions
Steel coils used for internal structural frames are also verified against the production order prior to release, including material source, batch number, thickness, and specifications.
A first-piece inspection is carried out before batch processing. Key inspection criteria include:
Dimensional accuracy
Straightness
Groove size
Uniformity of cold-bending angles to ensure proper fit with installation profiles
Upon approval, mass production is conducted according to production requirements. Enhanced inspection management is applied throughout the process, with continuous sampling inspections. Any detected defects are addressed promptly to prevent nonconforming components from flowing into subsequent processes.
3. Control of Templates and Fixtures
Templates and fixtures play a critical role in handmade panel production and directly reflect the level of manufacturing craftsmanship. Proper application and maintenance are essential for achieving consistent product quality.
Regular maintenance of templates is strictly enforced, including:
Clean and dust-free surfaces
No rust or residue
Proper flatness of scraper surfaces
Maintaining template flatness ensures uniform adhesive application, which is critical for achieving stable bonding strength and controlled curing time of the composite panels.
4. Production Environment Control:
Environmental control is particularly critical during adhesive mixing and application, where dust and humidity have the greatest impact on product quality.
Excessive dust may contaminate adhesive composition
High humidity can disrupt adhesive ratios, extend curing time, and reduce bonding strength
Extreme humidity conditions significantly affect production efficiency and final product quality
Our company strictly implements 6S management standards in workshop operations. Comprehensive cleaning is carried out prior to production, and humidity levels are closely monitored. To ensure bonding stability and curing performance, production is avoided under unsuitable environmental conditions, such as during rainy or high-humidity weather.
