Models & Replicas

Hapco has several formulations that are designed for mold making and part duplicating. In most cases, model makers will be hand mixing and pouring the casting resin into a mold cavity, typically silicone or polyurethane rubber, in order to duplicate a part. For model making applications demanding true “production part” characteristics, Hapco’s Ultralloy™ and Hapflex™ Series are popular choices. The Ultralloy™ Series includes several clear, white and amber materials that are available in different gel times depending on your processing needs. The Hapflex™ Series offers a wide range of durometers(20A to 72D) and fast or slow gel times depending on your process.
