With the development of the world automobile industry in recent
years the technology on rearview mirror is also greatly improved,
as demands a higher request on mold bricks in terms of its
performance and quality. We have been working on the research and
development. of Mold Bricks since 2000, and in March 2003 success
was achieved in the trial manufacture, in Sep 2003 a Mold Brick
production line was established, and we are now a factory
specialized on Mold Brick for Viewing Mirrors.
► MD Mold Bricks characterize as follows:
1. Low permanent linear change on reheating
Firing under the temperature of 1050 Degree. Ensures no distortion
and no permanent linear change on the mold bricks.
2. High dense structure
MD Mold Brick is manufactured from micron grade material, which is
pressed molding following being mixed by high speed blender. The
maximum rod is 1000 with extremely fine section structure. 3. Good
Thermal Shock Stability.
No cracks even chap would be happening after long service of the
4. Easy to be machined
The Mold Brick is manufactured based on the customer request, which
avoids waste from cutting of the big blocks.
We have established good fame among our customers since our mold
brick line was put into production with some performances superior
to similar products available in the market.
MD mold bricks could also be used in thermal bending glass, thermal
melting glass and art glass. We sincerely welcome the comments from
all our customers.
Besides the specifications as listed above we meet your
satisfaction based on customer requests, any problem don’t hesitate
