本发明描述了一种用于制造用于液体模塑的短切纤维预制件的独特工艺。一家公司从现有的浆料预成型技术开始，并对其进行了改进，以在穿孔金属筛上快速沉积纤维。该工艺具有许多优点，包括成本低、周期短、废料最少、材料选择的灵活性，以及最小的预制件放样。

A UNIQUE PROCESS FOR MANUFACTURING CHOPPED FIBER PREFORMS FOR USE WITH LIQUID MOLDING IS DESCRIBED. A COMPANY STARTED WITH EXISTING SLURRY PREFORM TECHNOLOGY AND REFINED IT TO PROVIDE RAPID DEPOSITION OF FIBERS ONTO A PERFORATED METAL SCREEN. THE PROCESS OFFERS A NUMBER OF BENEFITS INCLUDING LOW COST, SHORT CYCLE TIMES, MINIMAL SCRAP, FLEXIBILITY IN MATERIAL SELECTION, TOGETHER WITH MINIMAL PREFORM LOFT.
