Pre-start Preparation
Check Power and Air Supply: Ensure power lines are intact, air pressure is stable at 5–6 kg/cm², and the equipment is reliably grounded to prevent electrical leakage.
Lubrication and Inspection: Apply lubricant to transmission components such as guide rails and chains; manually operate the mechanism to ensure there is no binding or abnormal noise.
Material Parameter Setup: Select plastic sheet material of the appropriate thickness for the product, place it flat on the feeding rack, and configure parameters such as heating temperature, forming time, and cooling duration.
Dry Run: After powering on, perform 3–5 dry runs to observe whether component movements are synchronized and if the mold opens and closes correctly.
Operation and Forming
Feeding and Heating: Feed the sheet into the heating zone and preheat the oven for 10–15 minutes; adjust the heating time based on sheet thickness (e.g., approximately 20 seconds for a 0.5mm sheet).
Vacuum Forming: Once the sheet softens, initiate vacuum suction or air-pressure forming; carefully control suction temperature, duration, and vacuum level to ensure the sheet conforms tightly to the mold.
Cooling and Demolding: Rapidly set the shape using air or water cooling; after cooling, begin demolding from the loosest section of the mold, ensuring the product has fully cured.
Cutting and Removal: Trim excess material from around the workpiece using a blade and remove the part with specialized tools, avoiding direct hand contact with high-temperature components.
