Rubber Mold FAQ
Q: How do I properly store rubber molds when not in use?
A: Store rubber molds in a cool, dry place away from direct sunlight. Keep them flat or supported to prevent deformation. For long-term storage, apply a thin layer of talcum powder to prevent sticking and wrap in acid-free paper. Avoid folding or creasing the molds as this can create permanent deformation.
Q: What materials can I cast in rubber molds?
A: Our rubber molds are compatible with various casting materials including polyurethane resins, epoxy resins, polyester resins, low-melt metals (below 230°C/446°F), and wax. For materials requiring higher temperatures, we recommend our high-temperature resistant rubber molds (available upon request).
Q: How can I extend the lifespan of my rubber molds?
A: To maximize the lifespan of your rubber molds: 1) Always use appropriate mold release agents, 2) Allow proper cure time between castings, 3) Clean molds gently with mild soap and water after use, 4) Avoid using tools that might cut or tear the mold surface, and 5) Follow recommended demolding procedures for each specific casting material.
