Quality assurance
Approved samples, written specifications and agreed acceptance criteria create the shared standard for production and inspection.
Four-stage control
Across a 40,000 m² factory with eight production machines, the exact inspection scope depends on the product, decoration, intended use and buyer requirements. Third-party inspection can be coordinated when agreed before production.
Glass components, closures, accessories, packing materials and order documents are checked against the agreed requirements before use.
Critical dimensions, capacity, appearance, forming, color and decoration are checked during production against approved references.
Finished goods are reviewed using the agreed sampling plan and acceptance criteria for appearance, function and packing readiness.
Quantities, protective packing, carton marks, pallet plan and shipment documents are verified before dispatch.
Quality in context
These factory views show where in-process observation, finished-product review and outgoing preparation fit into the order workflow.




Before production
Inspection is most useful when the order specification states the measurable or visible requirements in advance.

Quality requirements
Include product drawings, defect limits, testing requirements and any third-party inspection instructions with your inquiry.
