    Core Characteristics and Requirements of Mold Manufacturing

    Extremely High Material Requirements:

    (1) High-quality mold steel, such as pre-hardened plastic mold steel P20, must be used.
    (2) Requirements include: high hardness (to resist abrasion from melamine powder), high wear resistance, good thermal conductivity (for heat exchange), and excellent corrosion resistance (to resist moisture and minor decomposition products).

    High Machining Precision:
    (1) The surface finish of the cavity/core determines the surface gloss of the molded product, typically requiring a mirror polishing level (#A1 or higher).
    (2) Dimensional tolerances must be controlled within ±0.05mm or even tighter to ensure product dimensional stability and precise parting lines.

    Heat Treatment Process:
    Mold steel must undergo heat treatment such as quenching and tempering to achieve the required hardness and toughness, extending its service life.

    Mold Cost and Lifespan
    (1) High Cost: A complex, multi-cavity, high-precision melamine mold represents the largest expenditure after equipment investment.
    (2) Extra-Long Lifespan: Under normal use and maintenance, a high-quality melamine mold can produce over 500,000 cycles, even millions of products. Therefore, it is a core fixed asset of the factory.
    (3) Maintenance: Regular cleaning, rust prevention, and inspection of venting channels and ejector pins are crucial for ensuring mold lifespan.

    Summary

    Melamine tableware molds are far more than simple "iron boxes"; they are high-tech products integrating materials science, precision machining, thermodynamic design, and extensive experience.

    Their core value lies in their ability to effectively and evenly transfer the "high temperature" and "high pressure" provided by the hydraulic press to the raw materials through extremely high precision, a perfect surface, and scientific thermal management. This allows them to stably and efficiently replicate millions of identical, high-quality products in the shortest possible cycle.

    FAQ 

    Question1:How to choose the right mold?
    We offer a comprehensive mold catalog for your selection. Alternatively, you can search for the desired mold in your local market, provide us with the product dimensions and weight, and we can offer a design or directly send us a sample, and we will produce the mold accordingly.

    Question2:What is the lead time for molds?
    Once the design is confirmed, the typical delivery time for molds is between 10 to 25 days. Please note that the lead time may vary depending on the quantity and design requirements of each customer.

    Question3:What is the minimum order quantity for molds
    The minimum order quantity for molds is one set, and we are happy to accept small orders.

    Question4:What are the reasons for the mold adhesion during the usage process?
    This might be due to the following situations:
    (1)The release agent has failed or the spraying is uneven.
    (2)The coating on the mold surface has worn out and the roughness has increased.
    (3)The excessive pressure and temperature have caused local carbonization of the melamine powder

    Question5:How to enhance the production efficiency of molds?
    Answer: Optimizing mold design (such as adding an exhaust system), regular maintenance, and choosing high-quality steel materials can all improve production efficiency.
