Batching & cullet
Silica sand, soda ash, limestone and controlled cullet ratios are weighed to recipe. Batch consistency is where colour and clarity are won — flint, amber or green to specification.
Melting
Continuous furnaces melt and refine the batch, eliminating seeds and cords. Temperature discipline here determines the optical quality of every article downstream.
Press & press-and-blow
Molten gobs are delivered to precision moulds. Tumblers and heavy-base articles press; hollow-ware press-and-blows. Mould temperature control keeps weight and capacity inside tolerance bands.
Lehr cooling
Articles travel through annealing lehrs on a controlled cooling curve that removes internal stress. We verify with polariscope checks — stressed glass fails in service, so it never leaves the lehr unverified.
Finish & decorate
In-mould embossing comes free with the forming; frosting, screen print, decals and colour spray are applied post-anneal and adhesion-tested for dishwasher and commercial-wash conditions.
Inspect, pack, stuff
100% visual inspection plus dimensional sampling per lot, then packing to your agreed carton structure, palletisation if specified, and supervised container stuffing with photo/video evidence.
