The published scope covers glass cloth, glass felt, kraft paper, and cotton-fiber webs, with impregnation, drying, rewinding, or cutting and stacking selected for the project.
Fiberglass Prepreg Lines
Vertical Fiberglass Prepreg Impregnation Line
The vertical prepreg impregnation production line is suitable for continuous impregnation, drying, winding or cutting of 7628, 2116, 1080 and other electronic-grade glass fiber cloth, felt, and paper. It adopts imported far-infrared heating panels with thermal-oil radiant heating and hot air drying, and multi-point temperature control on the left, middle and right sides. The prepreg surface is smooth, free of impurities and bubbles. The finishing adopts closed-loop servo control, multi-point tension control, and constant tension throughout the line.

Procurement guide
Buyer questions to resolve before quotation
Which process inputs define the line configuration?
Confirm web type and width, resin and solvent system, target resin content and gel time, line speed, drying profile, output form, and emissions treatment requirements.
How should shorthand values in the specification be handled?
Terms such as T/W, G/T, tension tolerance, and temperature tolerance should be expanded, assigned units, and linked to a stated sampling and test method in the technical agreement.
What evidence should be reviewed before acceptance?
Review the configured process diagram, supply boundary, control-point list, utility schedule, trial material plan, and agreed FAT criteria for the selected web and resin system.
