Case Study: Closed Mold Process Used on Innovative Combine Grain Extension Covers

The closed mold process is a method of working with resin that delivers many benefits. These include reduced waste and emissions, lower material and disposal costs, a more consistent, repeatable process, and reduced cycle times for higher productivity and lower labor costs. When dealing with composites, closed mold processes like light resin transfer molding (RTM), Read More…

Starting Resin Infusion

Before vacuum infusion processing (VIP or resin infusion), there was vacuum bagging. With vacuum bagging, a laminate is first wet out through an open mold type process, then covered in plastic and sealed. A vacuum is then pulled, which helps consolidate the laminate and pull out air and excess resin. From vacuum bagging came vacuum Read More…

Introduction to Vacuum Infusion

The vacuum infusion process (VIP) is a production process used to make parts out of fiber-reinforced polymers (FRP). Vacuum infusion uses negative pressure to pull-out air, while impregnating the reinforcement with resin. How VIP Works First, dry materials are place on either a male or female mold surface. Often, stitched or woven fabrics used, and Read More…
