Conventional Injection Molds

Simple or single-core/cavity molds are the most popular and where molding originated. There are still many uses for a “simple mold” and A1’s experience ensures a reliable, dependable and efficient mold that will last decades when properly maintained.  Conventional molds have evolved and may include multiple cavities, side actions, lifters, various materials (such as copper alloys), unique cooling methods, 3D printed parts, or conformal cooling inserts — all engineered to improve the mold’s performance.
