Advantages of Our Baby Bath Tub Molds
-
Safety-First Design & Finish: Molds are engineered to produce parts with generous radii, zero sharp edges, and impeccably smooth surfaces (high-gloss or soft-texture) to ensure complete safety for infant skin.
-
Optimized for Food-Grade & Hygienic Materials: Expertise in processing compliant PP and TPE/TPR, with mold designs that prevent material degradation and facilitate easy cleaning of the final product.
-
Efficient, High-Volume Production Design: Incorporating conformal cooling channels and robust ejection systems to achieve fast cycle times and consistent part quality, essential for meeting large-scale demand.
-
Integrated Functionality & Assembly: Capable of producing multi-component assemblies (e.g., tub body, plug, anti-slip mat) in family molds or with overmolding, reducing assembly steps and improving product integrity.
Quality Assurance
Our quality assurance protocol begins with the validation of food-grade material certifications. During mold manufacturing, we employ CMM and 3D scanning to verify all critical parent surfaces and safety radii. Finished molds undergo a comprehensive T1 trial, producing samples that are tested for dimensional accuracy, wall thickness uniformity, and required mechanical properties (like flexibility for TPE parts). We perform stringent sink mark and stress analysis via mold flow simulation prior to steel cutting. Our ISO 9001 certified process ensures every mold delivers parts that are not only precise but also inherently safe for their end use.
Our Factory
Our facility features large-bed CNC machining centers and deep-hole drilling equipment capable of manufacturing the sizable, complex cores and cavities required for bath tub molds. We operate high-tonnage injection molding machines (800-2500 tons) for mold trials and production validation. A dedicated polishing workshop ensures SPI A1/A2 class finishes. Quality is monitored with laser trackers for large-part dimensional verification and advanced surface roughness testers. Operating under IATF 16949 disciplines, our integrated process—from design and steel treatment to final tryout—ensures the delivery of robust, reliable tooling for the juvenile products industry.
