Die casting parts production and die casting die relationship

The role of die-casting die in casting quality

Die-casting mold is one of the three elements of die-casting production, the structure of the correct and reasonable die-casting mold is a prerequisite for the production of die-casting parts can be carried out smoothly, and plays an important role in ensuring the quality of castings.

Due to the characteristics of the die-casting process, the correct selection of the process parameters is the decisive factor in obtaining high-quality castings, and die-casting mold is able to correctly select and adjust the process parameters of the premise, die-casting mold design is essentially a comprehensive reflection of the various factors that may arise in the die-casting production is expected.

Die casting mold design problems encountered

If the die-casting mold design is reasonable, the problems encountered in the actual production of less, castings under the machine qualified rate is high. On the contrary, the die-casting mold design is unreasonable, such as: die-casting parts designed to move the fixed mold wrapping force is basically the same, and the pouring system is mostly in the fixed mold, and placed in the die-casting machine that can not feed the material after the pressure injection, can not be normal production, die-casting parts have been stuck in the fixed mold.

Even though the cavity of the fixed mold cavity finish hit very light, because the cavity is deeper, still appear sticky on the fixed mold phenomenon. So in die-casting mold design, must be a comprehensive analysis of the structure of the casting, familiar with the operation process of the die-casting machine, to understand the die-casting machine and the possibility of adjusting the process parameters, master the filling characteristics in different cases, and consider the die-casting mold processing methods, drilling and fixed form, in order to design a realistic, to meet the production requirements of the mold.

At the beginning, it has been said that the filling time of metal liquid is very short, and the specific pressure and flow rate of metal liquid is very high, which is extremely harsh working conditions for die-casting die, plus the impact of alternating stress of cold and heat, all have great influence on the service life of die-casting die.

The service life of a die casting die is usually the number of die castings (including the number of rejects in die casting production) that occur under normal conditions of use through careful design and manufacturing from injection mold design china, GM-Tech, combined with good maintenance and natural damage, before they can no longer be repaired and scrapped.

GM-TECH has been manufacturing plastic injection molds for a variety of industries for over 10 years. We also have experience in the automotive, home appliance plastic parts and appliance plastic molding, as well as making molds for other industries that require injection molds. We can provide you with a complete service in this area, from mold design to high quality manufacturing in their own tool shop. Enquiries are welcome.
