The mold is the "soul" of a hydraulic press; the shape, size, surface texture, and appearance quality of the final product are directly determined by the mold.

    Product Detail

    The mold is the "soul" of a hydraulic press; the shape, size, surface texture, and appearance quality of the final product are directly determined by the mold.

    In other words, the hydraulic press provides the "force" and "heat" required for forming, while the mold gives the product its "shape" and "appearance."

    Mold operation process (in conjunction with a hydraulic press)

    1.Preparation: Heat the mold to the set temperature. The operator cleans the mold and may spray a small amount of release agent.
    2.Adding materials: Pour the weighed melamine molding powder manually or automatically into the cavity formed by the lower mold and the middle mold.
    3.Mold closing: The hydraulic press drives the upper mold to move downward, enter the middle mold, and close with the lower mold to form a sealed cavity.
    4.Compression molding: Under high temperature and pressure, the powder melts, flows and fills the cavity, and then cross-links and solidifies.
    5.Mold opening: The hydraulic press moves upward, causing the upper mold to detach. At this point, the product usually remains on the lower mold.
    6.Ejection: The ejection mechanism of the hydraulic press pushes the ejection system of the mold to lift the product from the lower mold.
    7.Picking up: The operator or robot arm removes the product, completing one cycle.

    Summary

    The mold for melamine tableware is a precision, high-temperature, and high-pressure resistant steel tool. It is not just "a mold," but a complex system integrating mechanical structure, heating control, and surface science.

    •   The quality of the mold directly determines the product's appearance (gloss, color), feel (smoothness), and quality (shortage, air bubbles, flash, etc.).

    •   The design of the mold determines the efficiency and degree of automation in production.

    •   Mold maintenance (regular cleaning, polishing, and repair) is crucial to its service life and product quality stability.

    FAQ 

    Question1: Do we own our own mold factory?

    Yes, we have our own mold factory with over 16 years of experience, and we have been in the melamine tableware industry for more than 18 years. In addition, we also own factories for melamine tableware, raw materials, and machinery.

    Question2:Is custom mold design available?

    Yes, you can provide us with the images of the tableware you want, and we will create a design and manufacture the molds according to the desired size and shape. Alternatively, we can send you our mold catalog for selection and reference.

    Question3:What should we pay attention to when maintaining the mold?

    •   Daily: Clean the cavity regularly to prevent carbon deposits from the release agent.

    •   When shutting down: the mold must be cleaned and sprayed with anti-rust oil to prevent rust.

    •   Storage: The mold should be closed and stored to avoid bumps and dust.

    Question4:Why does the product stick to the mold and is difficult to demould?

    This may be due to insufficient release agent spraying, reduced mold surface finish, or unreasonable ejection system design. Regular spraying of release agent and maintenance of the mold surface are required.

    Question5:How long is the life of the mold?

    A high-quality and properly maintained mold can have a lifespan of more than 500,000 times, and some even exceed 1 million times.
