Centrifugal Casting Process
The raw materials, including resin, chopped reinforcement (fiberglass), and filler, are fed into the interior of a rotating mould according to a specific proportion. Due to centrifugal force the materials are pressed against the wall of the mould under pressure, and the compound materials are compacted and deaired. After curing the composite part is removed from the mould.
Storage
It is recommended to store glass fiber products in a cool, dry area. The glass fiber products must remain in their original packaging material until the point of usage; the product should be stored in the workshop, within its original packaging, 48 hours prior to its utilization, to allow it to reach the workshop temperature condition and prevent condensation, especially during cold season. The packaging is not waterproof. Be sure to protect the product from the weather and other sources of water. When stored properly, there is no known shelf life to the product, but retesting is advised after two years from the initial production date to ensure optimum performance.
