In the home bathroom, the bathtub is an important facility for improving the quality of life, and its quality directly affects the comfort and safety of bathing. The production of high-quality bathtubs is inseparable from precise bathtub molds.

As a leader in the mold industry, Micon Mould has accumulated rich experience in the design and manufacturing of bathtub molds, providing the market with numerous high-quality mold products through advanced technology and stringent standards.

Bathtubs need to withstand the weight of water and the human body for extended periods, making structural strength crucial. Micon Mould's engineers use finite element analysis software to simulate the strength of the bathtub mold's cavity structure, focusing on reinforcing the thickness and support structure of stress-bearing areas such as the bottom and walls.

Simultaneously, the mold's joints employ a precision sealing design to ensure no leakage after the bathtub is formed. For the edges and corners, the mold uses large rounded corners, improving safety, facilitating cleaning, and eliminating hard-to-reach areas.

Using professional 3D modeling software such as UG, Micon Mould constructed a precise 3D model of the bathtub, meticulously presenting every detail, including the location and size of the overflow and drain holes.

After modeling, mold flow analysis was used to predict the flow state of the plastic melt within the mold, optimizing the gate layout and venting system to address potential defects such as bubbles and shrinkage marks. For example, a multi-point symmetrical gate design was adopted in the large bathtub mold to ensure uniform material filling and reduce the impact of weld lines on structural strength.

Bathtub molds need to withstand high-pressure injection molding and long-term wear. Micon Mould selects suitable steel based on the bathtub material (such as acrylic, PP, composite resin, etc.). For ordinary household bathtub molds, 718H pre-hardened steel is commonly used, which combines machinability and wear resistance. For high-end engineering bathtubs, H13 hot work die steel is selected, which can reach a hardness of HRC45-50 after special heat treatment, extending the service life by more than 30%.

Rough machining and heat treatment: Micon Mould uses large CNC equipment to perform preliminary shaping of steel materials, remove redundant materials, and then perform tempering heat treatment to stabilize the internal structure of the steel and lay the foundation for subsequent processing.

High-precision milling: The mold cavity is precisely milled using a five-axis linkage machining center, with the machining accuracy controlled within ±0.02mm, ensuring that the surface flatness of the bathtub meets the standard.

Mirror polishing: The cavity surface undergoes multiple polishing processes to achieve a mirror effect with a Ra0.02μm, making the surface of the molded bathtub as smooth as porcelain and reducing water stains.

Assembly and trial molding: After all parts of the mold are assembled, Micon Mould will conduct multiple trial molding and debugging to check the smoothness of mold opening and closing and the stability of the ejection mechanism until the various indicators of the produced bathtub meet the standards.

Whether it's a compact bathtub for a small apartment or a whirlpool tub for a villa, Micon Mould can customize molds according to customer needs. For example, the molds designed for smart bathtubs can precisely reserve installation positions for massage nozzles and temperature control sensors, and are compatible with future functional upgrades.
