When mass casting a part without a flat side, you must create a two-part mold. We create a two-part silicone rubber mold with a clean parting line and then cast the part with Repro.
When a project requires a complex parting line, it is often easier to pour the entire mold in one process with clear rubber, then cut your parting line. This process also saves at least a day in creating the mold.
Ideal for smaller models/molds with a flat side, fast-cast urethanes are widely used for their ease of use, low cost, and quick demold times. However, their use requires careful application of release agents.
Ideal for smaller projects (less than 12" x 12"), this is the easiest process for creating parts, patterns, tools, & molds. We demonstrate creating a silicone rubber mold and then the casting of parts with Repro, epoxy casting resins and polyurethane elastomers.
Ideal for working on medium and large projects, this process invloves creating a thin layer of flexible material and backing it up with a stronger, rigid material.
Urethane Rubber molds are widely used when a flexible mold material is required and a more expensive or less abrasion-resistant silicone rubber is not desired. However, their use requires careful application of release agents.
This process is for working on medium to large projects, this is a labor-saving process for those who need a large, strong tool in the least amount of time possible. This video also demonstrates three-part mold construction.
Ideal for working on medium-sized projects, this process of pouring a high quality material around a lower quality core creates a highly accurate, yet economical part.
