Our achievement for Telescope aluminum maintube

Since 1988 we create Hydraulic Casting method for making a maintube of a Telescope. Few years later,

more advanced improvement method received an application for U.S. Patent NO. 5.813.107 dated SEP29

1998.

Further R&D, more stronger maintube by forging procession guide into manufacturing line during Q1 2009

Accordingly we complex machining these maintube, add relative components, well done, well performance

totally. Directly or indirectly supply to advanced famous brand around the world.
