ECR-Fiberglass Direct Roving for LFT-D/G
LFT-D Process
The polymer pellets and glass roving are melted and extruded through twin-screw extruder. Then the extruded molten compound will be molded directly into injection or compression molding.
LFT-G Process
The continuous roving is pulled through a pulling equipment and then guided into melted polymer for good impregnation. After cooling, the impregnated roving is chopped into pellets of different length.

ECR Fiberglass Direct Roving for Wind Power
Weaving Process
Weaving is the process of making unidirectional, multi-axial, compound fabric and other products by crossing two sets of threads over and under each other at weft, warp direction or +45° on weaving machine tor crossing ECR-glass direct roving and chopped strand mat together on stitching machine.

ECR-glass Assembled Roving for Spray Up
The assembled fiberglass roving for spray-up is coated with based sizing, compatible with unsaturated polyester and vinyl ester resins. Then it’s cut by the chopper, sprayed with the resin on the mold, and rolled, which is necessary to soak the resin into the fibers and eliminate air bubbles. In the end, the glass-resin mixture is cured into the product.
