Is the die-casting machine unable to inject material properly? 90% of people don't know these 5 reasons!

"Mr. Zhang recently encountered a troublesome matter: the die-casting machine in the factory suddenly became unable to inject material properly, and the production efficiency dropped sharply. With the delivery date of the orders approaching, he was at a loss. If you have also encountered similar problems, this article may help you find the answer."

Why is the die-casting machine unable to inject material properly?

The inability of the die-casting machine to inject material properly is one of the common failures, which may be caused by various factors. To solve this problem, first of all, we need to understand the reasons behind it.

• Problems with the hydraulic system: Contamination of hydraulic oil, wear of the oil pump or failure of the pressure valve may all lead to insufficient pressure.
• Problems with the mold: Excessive mold temperature, poor ventilation or unreasonable gate design will affect the injection effect.
• Improper setting of process parameters: Mismatch of parameters such as injection speed, pressure and holding time.
• Wear of mechanical components: Wear of the injection cylinder, piston or seals will lead to pressure loss.

How to diagnose the root cause of the problem?

Systematic troubleshooting can achieve twice the result with half the effort. It is recommended to diagnose according to the following steps:

• Check whether the pressure of the hydraulic system reaches the set value.
• Observe whether the mold temperature is within a reasonable range.
• Check whether the injection speed curve is normal.
• Check whether the mechanical components have obvious wear.

Key Note: It is recommended to use professional pressure testers and temperature measuring equipment. Data is more reliable than experience.

Practical Solution Sharing

According to the experience of the Zhongshitong technical team, the following solutions often achieve good results:

• Regularly replace the hydraulic oil and filters to keep the system clean.
• Optimize the mold cooling system to ensure uniform temperature.
• Recalibrate the process parameters and conduct DOE experiments if necessary.
• Establish a preventive maintenance plan and regularly check the key components.

Ms. Li's factory once encountered a similar problem. Through systematic troubleshooting, it was found that it was caused by the blockage of the hydraulic valve. After cleaning and replacement, the production efficiency increased by 30%.

Prevention Is Better Than Cure

Instead of solving the problem after it occurs, it is better to establish a perfect prevention mechanism:

• Formulate a detailed equipment inspection checklist.
• Train the operators to recognize the early symptoms of failures.
• Establish an equipment operation data file.
• Maintain long-term cooperation with professional maintenance teams.

Key Note: Many serious failures have early manifestations. Timely detection can avoid greater losses.
