In modern plastic manufacturing, the flexibility and adaptability of blow molding machines play a decisive role in productivity and product quality. To meet diverse requirements for different shapes and capacities, mold changing has become an essential part of production. A standardized and systematic mold change process minimizes downtime and ensures stable, efficient production. At Shandong Great Machinery, our team of professional engineers provides full guidance throughout the process, making us a trustworthy partner for your operations.
1. Removing the Old Mold
Once the production plan requires a mold change, the first step is to dismantle the old mold. Depending on the machine type, engineers loosen bolts, disconnect clamps, or detach hydraulic fittings. For larger molds, lifting devices are employed to ensure safety and precision. The old mold is carefully moved to a designated storage area, ready for cleaning and maintenance. This step requires close coordination between operators and the machine to avoid potential damage.
2. Installing the New Mold
The new mold is positioned with the help of lifting tools and aligned precisely with the machine’s clamping system. Engineers then secure the mold using bolts or hydraulic clamps, ensuring it is properly oriented and evenly seated. Auxiliary systems such as cooling lines and sensor connections are attached and carefully checked. Only after confirming that all connections are correct and reliable is the mold fully locked in place.
3. Testing and Trial Production
After installation, engineers run the machine at low speed to test the mold. Parameters such as air pressure, material flow, and wall thickness are closely monitored. The first few molded products are carefully inspected for appearance, dimensions, and structural accuracy. If any deviation is found, minor adjustments are made until the mold performs flawlessly. This step is crucial to ensuring that mass production proceeds smoothly without unexpected issues.
