Centrifugal Casting
Centrifugal casting is used for cylindrical, hollow applications such as tanks, pipes and poles. Chopped strand mat or fabrics are loaded into a stationary mold which is then rotated at a high speed. Resin is applied to the interior of the mold and the reinforcements and resin are consolidated through centrifugal force to the internal profile of the mold. Chopped multi-end roving can be sprayed with resin into a cylindrical mold that is already rotating at high-speed.
Available resin vendors: Ashland( good resin and gelcoat ) -US advantage - have plant in china
DSM ( good resin and gelcoat ) -EU advantage - have plant in china
Scott Badder -EU advantage and Middle East.
Interplast -US advantage
Hexel (Eastman) -EU and US advantage
Addition: there is several resin vendors around the world, each composites exhibition you can make it to know them.
For this process, composites man utilizing :
1. Direct Roving ( tex or Yield 496052) .
2. Spray Up Roving( tex or Yield 496052) .
3. Continuous Filament Glass Fiber Mat. Chinese glass fiber vendor have not good tensile strength
for Continuous mat. the two problems are : one , the tensile strength not suffecient and result
in mat easy to tearse or broken , then entire composites will be waste. other is glass fiber can
not spray out ever uniform and have not steady average unite weight , this is make resin
could not be impregating well.
4. Multi-Axis Fabrics 600g/m2 and 850 g/m2 ( +/- 45) ,
roll width 1270mm. Describe as EMK 850(+/-45)-1270 . North American composites
monsters like use inch and Oz for dimension measure way.
5. Chopped Strand Mat ( European monsters like emulsion mat ,
**Northern American like powder mat) , unit weight :
225 / 300 / 450/ 600/ 900 g/m2
**roll width :
965 / 1000/ 1040 / 1250 / 1270 /1270 with trim / 1524 mm
( 50 / 60 inch is standard)
6 . Woven Roving
Unit weight : 300/450/ 600/900 g/m2
Roll width : the most as usual as CSM
7. Sometime, people use combomat, chopped roving with mat or woven roving with mat.
8. Surface tissue mat ( Surface Veil ) 30 g/m2 , 50 g/m2 , 60 g/m2 is usual type.
9. My passion: my passion help my customers to find most economy and compared good quality
from china. also, if somebody crazy, i can sell PPG fiberglass back to china .
