Q: What is the primary function of a GRP winding machine?

A: A GRP winding machine manufactures cylindrical fiberglass-reinforced plastic (FRP) products like pipes and tanks. It precisely winds resin-saturated glass fibers onto rotating mandrels under tension. This ensures uniform structural strength and custom laminate thickness.

Q: Which industries typically use FRP winding machines?

A: FRP winding machines serve industries requiring corrosion-resistant structures. Key sectors include water/wastewater treatment, chemical processing, and oil/gas. They produce storage tanks, pipelines, and pressure vessels efficiently.

Q: What materials do fiberglass winding machines handle?

A: Fiberglass winding machines process continuous glass fiber rovings or mats saturated with resins like polyester, epoxy, or vinyl ester. Optional components include silica sand for abrasion resistance or structural cores. Material combinations enhance product durability.

Q: What advantages do GRP winding machines offer over metal fabrication?

A: GRP winding machines create lightweight, non-corrosive products with high strength-to-weight ratios. Automated winding reduces labor costs and ensures consistency. Resulting FRP structures outlast metals in harsh chemical environments.

Q: How do operators control product specifications on an FRP winding machine?

A: Operators program parameters like fiber tension, winding angle, and resin ratio via PLC systems. Mandrel rotation speed and carriage traverse are adjusted for precise layer deposition. This allows customization of wall thickness and mechanical properties.
