Four Common Problems and Solutions in Plastic Mold Forming
Problem One: Scorching Scorching is the premature vulcanization of plastic, where poor mold flow causes deformation or incomplete parts before the plastic flow is complete. To prevent or eliminate scorching, ensure the mold is fully filled before vulcanization begins and that the mold cavity is evenly heated.
Problem Two: Backflow This is the deformation of molded products at the mold parting line, often appearing as tears or rugged indentations. Backflow is usually caused by the sudden release of internal pressure when the mold opens. To prevent it, avoid rough or excessive openings at the parting line and maintain the molding temperature as low as possible with the vulcanizing agent used.
Problem Three: Entrapped Air Air trapped in the plastic mold or plastic can cause soft, discolored areas on the surface or cross-section of molded parts due to incomplete vulcanization. Solutions include: 1. Colliding the mold. 2. Increasing the amount of vulcanizing agent. 3. Using high-temperature vulcanizing agents with lower air reactivity. 4. Venting at sharp corners and undercuts of the mold.
Problem Four: Surface Discoloration This is often due to excessive buildup of release agent in the plastic mold cavity or too much dust or dirt in the preform. To prevent such issues, clean the mold regularly, keep preforms clean, and use release agents cautiously.
