2 LOW PRESSURE INSERT MOLDING Henkel, the global leader in adhesives, and The Cavist Corporation, application engineering and equipment experts in the field of low pressure insert molding, have partnered to offer a complete solution for the gentle over-molding and encapsulation of delicate electronic components. Low pressure molding is an innovative manufacturing process between injection molding and potting. It is injection molding at very low pressures with hot melt adhesives. It is a cost effective alternative to epoxy potting for protection of fragile electronic components. When used for cable and connector molding, it offers superior strain relief compared to conventional plastic injection molding. The Low Pressure Molding process provides many benefits. Complete sealing of the components, providing water-tight encapsulation Effective strain relief Low viscosity materials allow for low injection pressures of 20 to 500 psi Allows gentle pre-molding of connectors Components and wires are not damaged or dislocated in cavities Easy to encapsulate fragile components No hazardous fumes from materials or processing Short (15-45 seconds) cycle time to complete part Process Flow Advantage of Low Pressure Molding TRADITIONAL POTTING PROCESS FLOW LOW PRESSURE PROCESS FLOW

5 HENKEL MACROMELT LOW PRESSURE MOLDING MATERIALS Henkel is the world leader in high performance adhesive materials. The Macromelt OM line of low pressure molding materials are innovative, specially-modified thermoplastic polyamide hot melts made especially for low pressure molding. Macromelt products melt and flow at low viscosities (1,000 to 10,000 cps), allowing for the low injection pressure process. Macromelt offers very good adhesion to various substrates, including PVC, PA6.6, PUR, and PP. Since they are based on adhesive technology, they bond to form a watertight and chemical seal. These hot melts cure quickly by cooling so there are no toxic fumes and cycle times are short. The entire line of Macromelt OM products is UL94-V0 rated. The materials are available in amber, black and custom colors.
