Because automatic die casting machine has a wide range of applications, its troubleshooting has always been one of the core issues in the field of die casting. The maintenance and repair of cold chamber die casting machine have important guiding significance in formulating reasonable die casting process parameters and improving die life. In addition, how to reduce the failure rate of nonferrous metal die casting machine from the source, we also give suggestions in this article.

 

Here is the content list:

  • What is the normal operation when the die casting machine fails?

  • How to deal with different die casting machine oil pump failures?

  • How to solve the problem of die casting machine relay?

  • How to reduce the failure rate of die casting machine from the source?

 

What is the normal operation when the die casting machine fails?

In the working process, once the die casting machine failure occurs, the operator should pay attention to it, observe it calmly, determine the location of the failure and the possible cause, and determine the feasible maintenance method.

As a responsible die casting machine manufacturer, we must remind operators that they should work in accordance with the operating rules formulated by the company. Do not operate in violation of regulations to avoid greater accidents.

To deal with machine failures, whether it is a hot chamber or cold chamber die casting machine, you can follow the steps below:

1.        Judge the type and location of the fault by watching, listening and testing.

2.        Analyze the possible causes of the failure.

3.        Check equipment operation records and relative files.

4.        Determine the corresponding processing methods and work steps.

5.        Carry out maintenance operations.

 

How to deal with different die casting machine oil pump failures?

If the oil pump of the die casting machine cannot be started, it needs to be inspected and analyzed in time. The operator can try to press the start button of the oil pump to observe whether the motor relay is closed.

If the relay is not closed, check whether the thermal relay of the motor is activated or damaged. Use a multimeter to check whether the power circuit is normal, whether the start and stop button contacts are normal, whether the control circuit is open, and whether the relay coil is damaged.

If the relay is closed after the die casting machine oil pump is started, check whether the oil pump is damaged or stuck, whether the line from the relay to the motor is normal, whether the oil pump is damaged or the assembly is too tight.

 

How to solve the problem of die casting machine relay?

If you press the start button of the oil pump, and the thermal relay goes tripping, it is related to load, current and whether three-phase resistance are symmetrical.

The operator should check whether the motor thermal relay is damaged or the setting current is too small, whether the current is increased due to the low voltage or the three-phase voltage is unbalanced, and whether the resistance of the three-phase winding of the motor is unbalanced.

In addition, the total pressure adjustment of die casting machine is too high, the oil pump is damaged or the assembly is too tight, it will also cause the machine to overload and trip.

 

How to reduce the failure rate of die casting machine from the source?

The selection of die-casting machine is an important part of the preliminary preparation for die-casting production, and it is a highly technical and comprehensive work.

The product requirements, process configuration, and management requirements of different companies are distinct, and the focus of the choice of die casting machine is also different.

Some die casting machine manufacturers do not have their own processing methods. All parts are assisted in production by outsourcing. Even the same kind of parts are processed by several outsourcing units, which is no inspection report after the outsourcing has been completed. This kind of machine often fails.

Therefore, when purchasing a die casting machine, consumers should look at the manufacturer’s production qualifications to determine whether they are truly qualified to operate die casting machine business.

Secondly, consumers also need to see whether the factory is attentive to the configuration of the machine, and whether there is any new technology in the die casting machine.

Finally, consumers have to ask whether the manufacturer can provide useful help on-site, such as remote or on-site technical guidance. After all, at the beginning, many customers who just started the die casting business have a lot of professional knowledge not clear.

 

After years of development, the domestic automatic die casting machine is no longer far behind the foreign industry as before. And although foreign high-tech metal die casting machines are well-known, in fact, replacement parts are not easy to buy. Longhua Die Casting Machine Co., Ltd is based on the domestic market, has the world's leading cold chamber die casting machine technology, and provides you with 24x7 thoughtful service. If you are interested in cooperation, please consult our customer service.
