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.
