Why can't the cull, sprue, and runners from a transfer molding operation be reprocessed as regrind like runners in an injection molding operation?
What will be an ideal response?
In a transfer molding operation the cull, runners, and sprue are made from thermoset materials that cannot be remelted, which is required for reprocessing as regrind material. In injection molding the runners and sprue are made from thermoplastics that can be remelted and reprocessed as regrind.
