Certificates & Quality Control
Hongli Stamp uses practical production inspection steps to help wholesale buyers reduce quality risk before shipment.
Quality Control Process
If a buyer needs formal documents, we can discuss available business license, material safety information, inspection records, brand authorization or project-specific test requirements before order confirmation.
Incoming Material Inspection
Stamp housings, rubber sheets, pads, ink and packaging materials are checked before production.
Printing & Impression Test
Logo artwork and rubber plate output are checked through sample stamping before bulk production.
Stamping Life Test
Selected models can be tested for repeat stamping performance and stable impression quality.
Ink Leakage Test
Ink pads and finished self-inking stamps are checked to reduce leakage during packing and shipment.
Pre-Shipment Inspection
Quantity, color, model, packaging and carton marks are checked before delivery.
OEM Order Confirmation
Logo, private label packaging, barcode and carton requirements are confirmed before final shipment.
