Quality Control
Good material. Clear standards. Repeatable results. A practical quality framework from material selection and in-process review through final packing inspection.
Quality is a process, not a checkpoint
We inspect at incoming, in-process and finished stages so problems are caught early and never reach your customers.
Incoming material control
Every batch of corrugated cardboard is checked for flute profile, density, moisture and odour before it enters production.
- Supplier CoA review
- Flute & density sampling
- Moisture & odour check
In-process inspection
Operators and line QC monitor die-cutting, sawing and printing in real time to catch deviations early.
- First-article approval
- In-line dimension checks
- Print colour matching
Finished product testing
Random and full checks on assembled goods verify structure, safety and pack readiness.
- Load & stability test
- Edge & safety check
- Drop & packaging test
Stay Focused,
Stay Professional.
A repeatable cat scratcher depends on paper structure, glue control, cutting accuracy, stability, artwork and carton protection.
Zhizao's workflow is presented around professional printing, controlled die-cutting and sawing, skilled mass-production workers, and considerate pre-sales and after-sales service.
Checks at every critical step
Each check answers a practical question: does the material behave, does the structure hold and does the packed product arrive as approved?
Material & moisture
Before production begins, the team checks the board's condition, thickness and surface consistency. Stable material makes downstream cutting, bonding and forming easier to control.
Die-cut accuracy
Cutting and forming are reviewed while the line is running. The aim is a clean profile, reliable fit and a repeatable shape across the approved production quantity.
Print consistency
Artwork and surface treatment are checked for legibility, placement and consistent coverage, so the product looks as intentional in a batch as it did in the approved sample.
Structure & edge finish
Before packing, finished pieces are checked for stable assembly, clean edges and the tactile details that make a cardboard scratcher feel ready for everyday use.
Packing readiness
Packaging is part of quality. We check protection, labelling and quantity before finished units move to the warehouse or into a customer-ready shipment.
Stringent final product inspection.
The final look brings the process together: structure, finish, artwork, packing and the small details that determine whether a product feels ready to use.
Certifications show our attitude.
Our factory and product documentation gives customers a clearer way to review management systems, responsible sourcing and material compliance.
