Die-set “upper 1 - lower 2”

As a proFessional manufacturer ,XGIMI would like to provide you high quality die-set of powder molding machine. The die-set “upper 1 - lower 2” features a single upper mold and two lower molds, with both lower molds in contact with the powder material simultaneously during the molding process. This design offers several advantages over the “upper 1 - lower 1” configuration, particularly in terms of molding speed and pressure distribution.

One of the key benefits of the die-set “upper 1 - lower 2” is its increased molding speed. By using two lower molds instead of one, the machine can complete the molding process in less time, effectively doubling the production capacity. This makes the die-set “upper 1 - lower 2” an ideal choice for high - volume production applications where speed and efficiency are essential.

In addition to its faster molding speed, the die-set “upper 1 - lower 2” also provides more uniform pressure distribution. With two lower molds in contact with the powder material, the pressure is spread more evenly across the mold cavity, resulting in better compaction and more consistent product quality. This is especially beneficial for molding large or complex components, where uneven pressure distribution can lead to defects such as voids, cracks, or density variations.

However, the die-set  “upper 1 - lower 2” also has some drawbacks. The increased number of molds in contact with the powder material results in higher friction and wear on the mold surfaces, which can reduce the mold life and increase maintenance costs. Additionally, the presence of two lower molds may make it more challenging to achieve a high - quality surface finish on the molded products, as there is a big risk of surface imperfections caused by the interaction between the molds.
