MOSTRO Induction Sheets Testing by Hydraulic Machine with Indian Clients | MOSTRO | 2025

Today, the global manufacturing industry is closely linked, and transnational cooperation has continuously collided with the spark of innovation. Today, we welcome a group of important partners - guests from India, to witness and participate in the hydraulic testing of the die casting mold.

As the test begins, the hydraulic equipment is activated and pressure is gradually applied to the mold. In this critical testing process, every link is related to the success of the test, among which there are several key considerations should not be underestimated:

Make sure the film is oil-free: 

Die casting process, the film is strictly prohibited to have any oil residue. This is because even the slightest oil mark, under the strong pressure and force generated by the die-casting moment, will make the composite film as sliding on the ice generally out of control, unable to accurately position. This will not only lead to the deviation of the mold bottom position, directly affect the molding quality of the mold, but also may make the entire test data lose reference value and delay the project schedule.

Pay attention to the aluminum sheet material: 

In this test, the hardness of the aluminum sheet provided by the customer exceeded the expectation, which brought no small challenge to the die casting work. The hard aluminum sheet makes it difficult to achieve the ideal forming effect under the action of pressure, and problems such as uneven indentation and shape deviation may occur. Our technicians need to always pay attention to the state of the aluminum sheet in the die casting process, adjust the process parameters in time, such as appropriately increasing the pressure or optimizing the die casting time, in order to overcome the difficulties caused by the hard aluminum sheet.

Matching the right tonnage: 

For the die casting of pizza pans, the required pressure has strict requirements, and the tonnage of the equipment must be 2,500 tons. Only enough pressure can make the mold fully contact with the aluminum sheet and form, if the tonnage is insufficient, the edge of the pizza pan may not be fully closed, and the surface smoothness is difficult to ensure. During the testing process, we have to double-check the pressure parameters of the equipment to ensure that the tonnage requirements of the pizza plate die casting are met.

Precise control of the pressure rise rate: 

The pressure rise rate must be steadily increased in strict accordance with the pre-set rate. Too fast pressure mutation is like suddenly applying a heavy hammer to the mold, which is easy to cause the stress concentration of the internal structure of the mold, causing mold deformation and even cracking, and destroying the expensive mold. Technicians need to keep an eye on the pressure value at all times, and once there is an abnormal fluctuation, they must immediately and decisively press the pause button, comprehensively investigate the cause, and ensure that the pressure is stable before continuing the test.

After a series of strict testing procedures, finally, the perfect test results are presented in front of us. The bottom of the die casting mold has withstood the test, and every index has reached or even exceeded the expectation. There were satisfied smiles on the faces of the Indian guests, and both sides warmly shook hands to celebrate the successful test. This cooperation is not only the exchange of technology, but also the enhancement of friendship, and we look forward to working together in more fields in the future to create more brilliant.

please do not hesitate to contact us. We will be happy to serve you in any way possible.
