? Detailed Recommendations
? Class 100 cleanroom, standard geometry: Directly consider machine-formed cleanroom panels — better airtightness and surface precision. SAMZOON provides free samples for physical verification.
? Complex shapes, non-standard openings: Hand-formed panels may be necessary — but verify worker skill and quality control.
? Large-volume standard cleanroom: Machine-formed panels offer lower cost and faster production.
?️ Combination approach: In some projects, machine-formed panels are used for standard walls, while hand-formed panels are used for complex openings.
? Key Takeaways
? Machine-formed panels offer better airtightness (±0.5mm joint tolerance), consistent surface precision, and faster production — suitable for Class 100 cleanrooms.
? Hand-formed panels offer flexibility for complex shapes and non-standard openings — but quality depends on worker skill.
? Airtightness: machine-formed panels have better airtightness — critical for Class 100 cleanrooms.
? Surface precision: machine-formed panels have consistent thickness and flatness; hand-formed panels may vary.
? Scenario-based selection: machine-formed panels for standard cleanroom walls; hand-formed panels for complex shapes.
? SAMZOON provides both machine-formed and hand-formed cleanroom panels, with selection guidance based on cleanroom class and geometry for South China projects.
