  • Ultrasonic edge sealing of sheet molding compound carrier film
    Patent number: 9937659
    Abstract: A process for manufacturing a sheet molding compound carrier film including a first layer of material and a second layer of material sealed with each other along an edge. The seal is formed using ultrasound transmitted by a weld horn as both layers of material move along an anvil portion. The seal on the edge is suitably formed to protect the edge and build a weld to ensure moldable sheet molding compound flows to the edges of the carrier sheet, while providing a homogeneous mixture of glass and resin and also allowing air to escape.
    Type: Grant
