Key Points and Safety Instructions for Mold Start‑up

“Mold start‑up” in actual production is a comprehensive process involving preparation, inspection, and operation. It usually refers to the start‑up and trial run after mold installation, or pre‑heating before production – sometimes confused with the “mold opening” action. The core operating steps are as follows.

I. Standard Operating Procedure

1. Pre‑start Preparation and Inspection

• Cleaning and inspection: Ensure the mold inside/outside and cavity surfaces are free of oil, residue, and foreign objects. Check that cooling channels are clear, electrical circuits are normal, and safety devices are effective.

• Mounting and fixing: Lift the mold onto the machine in the correct position, slowly close the mold, evenly tighten the clamping plate bolts, and adjust the mold level.

2. Start‑up and Pre‑heating

• Start hydraulic system: After confirming the equipment is in good condition, press the motor start button and let the oil pump idle for 2‑5 minutes, listening for abnormal noise.

• Pre‑heat the barrel: Set the temperature according to the material. After the barrel reaches the set temperature, normally hold for another 30‑60 minutes to ensure uniform plasticization.

3. Trial Run and Production

• Test run: In manual mode, perform low‑pressure, low‑speed mold closing and opening, checking that the stroke and ejection are smooth.

• Parameter adjustment: Gradually switch to semi‑automatic or fully automatic mode, observe product quality, and fine‑tune the parameters.

II. Safety Instructions

1. Equipment and Personal Safety

There is high‑voltage danger in the mold area. Always shut down power when mounting the mold. Never start the machine if safety devices such as the safety door are ineffective. Strictly follow the rules.

2. Operation Monitoring

During fully automatic production, ensure the part is completely ejected and detached; otherwise, mold closing may crush the part and damage the mold.

3. Special Reminder for Restart After Holidays

First check the electrical cabinet cooling fans and the water/oil circuits. When first starting, it is recommended to reduce pressure by 30% and run at low speed, and verify that the mold is firmly secured.
