The plant
Wei County, Hebei — 10 sealant production lines, 10,000 tonnes a year, and a team of over seventy. Everything from mixing to cartoning happens on one site.
What happens on site
Mixing
Polyurethane, STP and PUR systems are batched separately. Pigment and filler dispersion is where colour consistency is won or lost — the same RAL looks different if the filler load moves.
Filling
310 ml cartridges, 400 and 600 ml sausages, 200 L barrels and 5 ml–1 L cans. Filling is where air entrapment shows up, so the line is set per pack format rather than run at one speed.
Testing
Batch samples are checked against the properties listed on the model page — tensile, elongation, skin time, hardness, density. The methods are on the quality page.
Packing
Cartons to the approved artwork, pallets mixed across models for distributors, and export packing agreed with you at quotation stage.
Where it ships
Export orders leave from Hebei; tell us the port you want quoted and the documentation your broker requires. Labelling and origin paperwork differ enough between markets that discovering the gap at loading costs a week.
