During the final trial test of the tile leveling system mold before shipment, the following key steps must be strictly followed to ensure mold quality and production stability:

Pre-Trial Preparation

• Mold Inspection

  • Verify that the mold has no damage from transportation or assembly (e.g., wear, deformation, rust), focusing on critical parts such as locating pins, ejector pins, and runners.

  • Cross-check mold dimensions (especially key tolerances like clip spacing and thickness) against design drawings.

• Machine Setup

  • Calibrate injection molding/pressing machine parameters (pressure, temperature, cycle time) to match mold specifications.

  • Material preparation: Use the same raw materials (e.g., PP/ABS) as in mass production to avoid deviations.
