Add an appropriate amount of PVC stock solution and PVC special color paste into the injection machine, set to 170℃, and start heating.
After heating is completed, use the injection machine to inject material into the mold's injection port (push the plunger until it cannot be pushed further and hold for 3-5 seconds to remove larger bubbles).
After injection, wait 6-8 minutes to allow the PVC soft gel to cool.
After cooling is complete, open the mold and tap the entire tire out through the opening shown in Figure 2. Cut along the circled section in Figure 3, then remove the two center mold halves. When demolding, gently separate the soft rubber from the mold to avoid damaging the soft rubber model by excessive force.
