Quality Assurance
Zero Defects:
Inside Bestway’s QC Protocol
Quality isn’t an accident. It’s the result of strict adherence to the 4M1E (Man, Machine, Material, Method, Environment) standard.

1. Incoming Inspection
MATERIAL
Before First Piece Confirmation
TPE Sheet Inspection: Must be free of impurities and agglomeration (no black dots).
Physical Properties: Hardness must be uniform; Thickness must meet the specific gauge standard.
Sensory Check: Zero Odor test and strict color consistency check.
2. Vacuum Forming
MACHINE & METHOD
The most critical stage. We perform a strict First Piece Confirmation before mass production begins.
A-Surface (Appearance)
No Water Marks/Stains
No Over-cutting/Flash
Texture must be 100% sharp
Key Area Thickness Check
B-Surface (Back Side)
Minor tooling marks or paint indicators are acceptable on the non-visible side, provided they do not affect structural integrity or fitment.
3. Trimming & Assembly
MAN
Hand-Finishing Standards
Trimming: Edges must be smooth. No jagged “burrs” or flash remaining.
Clip Installation: Hole diameter must be precise. Clips must be installed tightly with zero play.
Durability: Clips are stress-tested to ensure they are not fragile.
4. Packaging & Dispatch
ENVIRONMENT
Identity: Logo sticker installation is verified for alignment.
Protection: Plastic seal bag applied for dust isolation.
Traceability: Shipping Marks checked against order manifest.
Final Random Inspection: A final sample check is performed before sealing the carton.
