Quality, by design

A production network built for ceramic mugs — and the checks that keep it consistent.

Our exclusive Liling production network brings together a 1994-built factory, six production bases, ten branch factories and twenty kilns. Every program runs through the same team, the same standards and documented QC.

Production is planned by kiln, not by promise. In-process checks, batch traceability and a photo QC report before shipment keep the batch visible to your team before it leaves Liling.

Quality in every step

Three checkpoints before a mug leaves the line

A custom mug is not inspected only at the end. The checks start before the sample and continue through every batch.

STEP 01

Pre-production

Artwork and technical assessment — body, capacity, decoration and packaging are reviewed before sampling. Material verification and master-sample approval happen before a line is booked.

STEP 02

In-production

Forming, glazing, printing and firing checks at defined intervals. Colour difference, print position and kiln records are logged for every batch.

STEP 03

Final-production

Dimensional and cosmetic inspection, drop test, food-contact test reports, packing verification and a photo QC report before shipment.

Manufacturing standards

What we control in-house

The process is managed as one system — from the body and glaze to the print, firing and final carton.

Quality management

A documented quality system covers every order — from approved artwork and master sample to final inspection and shipment release.

Material verification

Glaze, clay and decoration materials are checked against the approved specification, with batch records kept for traceability.

Process control

In-line checks at forming, glazing, printing and firing keep colour, print position and body dimensions within specification.

Final inspection

A defined inspection plan covers appearance, capacity, handle strength, drop test and packaging before cartons are sealed.
