Analysis of Bakelite Injection Mold Design Points

Bakelite mold design differs significantly from thermoplastic molds. Key points: 1) Mold must be heated (not cooled), typically with electric cartridge heaters or oil circulation, 2) Material is abrasive, so mold steel must be wear-resistant (hardened tool steel), 3) Venting is critical for gas evacuation during curing, 4) Draft angles of 3-5 degrees minimum for demolding, 5) Hot runner or insulated runner design for thermoset materials.
