Production Flow

Seven stages, one production line.

Basalt Melt
01

Basalt Melt

Selected basalt and slag are melted in a cupola furnace at 1500 °C — the chemistry is the foundation of every property the finished product offers.

Fiberisation
02

Fiberisation

Molten rock is spun on a four-roller wheel into long, thin fibres while a binder and water-repellent agent are atomised onto the fibre curtain.

Pendulum Layering
03

Pendulum Layering

Fibres are laid into a thick mat. Pendulum oscillation cross-laps the layers — this is what gives our facade boards their dimensional stability.

Curing Oven
04

Curing Oven

The mat passes through a curing oven where the binder cross-links and the product reaches its final density and strength.

Cutting & Lamella
05

Cutting & Lamella

Boards are cut, lamella-rotated for sandwich-panel cores, film-faced or mould-formed into pipe sections for industrial insulation.

QC Laboratory
06

QC Laboratory

Every batch is tested in our on-site lab — density, tensile strength, water absorption, thermal conductivity, fire and chloride content.

Packaging & Logistics
07

Packaging & Logistics

Finished goods are wrapped, labelled, audited and prepared for export through Ningbo, Shanghai or Shenzhen.
