How should mold changeover time be tested on a commercial mooncake forming machine?

Time the complete changeover from shutdown through removal, installation, positioning, and the first accepted product. For multi-product use, test representative low, medium, and high operating points to reveal the available adjustment range. If several specifications are required, document each setting so future operators can reproduce the approved process. Do not accept an unspecified “maximum capacity” claim when the real application requires a defined quality level. This information also helps the buyer estimate utilities, staffing, spare parts, and expected maintenance requirements before installation.
