Selected disclosures assembled into a continuing object history. Associated business context retains its own company, product or site scope. Source-page links provide optional verification; the English account is intended to stand on its own.
Read the dated construction and operating milestones below. An installation stage or an engineering-progress percentage does not establish actual production. A programme and its component lines may describe the same capacity at different levels.
Exact physical address and coordinates have not yet been verified for this record.
Verified site coordinates: unavailable. No city-centre point is displayed as a plant location.
The following sections retain the full available English descriptions and their source context. Associated business context describes its named product or base.
Chengdu base line 4, a 60,000-tonne medium-alkali glass fiber tank-furnace drawing line, entered production in July 2008. It has a different line number, chemistry and scale from the January alkali-free addition. Both developments belong to the Chengdu manufacturing base. Their commissioning milestones do not establish each line's full-year output or customer mix.
