Overview
Our Custom High-Precision Injection Molding Tooling for Baby Toilet Seats is engineered for safe, durable, and cosmetically perfect baby-care components. Built for single- and multi-shot molding of rigid shells and soft TPE cushions (2K / overmolding), these molds deliver tight dimensional control, glossy hygienic surfaces, and robust cycle life for high-volume production. Each tool is optimized for clean demolding, minimal flash, balanced filling and fast cycle times—helping OEMs bring safe, child-friendly toilet seats to market quickly and reliably.

Key Advantages
- Precision fit & ergonomics: Controlled shrinkage and tight tolerances ensure secure hinge fit, consistent snap-in clips, and ergonomic contours for toddlers.
- 2K / Overmolding expertise: Integrated tooling solutions for rigid shell + soft TPE cushion — bonded in a single cycle for superior comfort and leak protection.
- Cosmetic excellence: Mirror-polished cavities and controlled gate placement produce high-gloss, easy-clean surfaces with no gate blemishes on visible faces.
- Hygiene & safety design: Materials and parting allow for smooth radii, easy cleaning, and design features that minimize crevices where bacteria can accumulate.
- Thermal stability & cycle efficiency: Advanced cooling layout reduces cycle time and part warpage while maintaining dimensional stability.
- Durability & low maintenance: Hardened steel options, PVD coatings and nitriding extend tool life and reduce downtime.
Surface Treatment Options
- Mirror Polishing (SPI A1) — for high-gloss, hygienic finishes.
- Texturing (MT / SPI) — anti-slip or matte cosmetic finishes.
- Hard Chrome / Nickel Plating — wear resistance for abrasive polymers.
- Nitriding / PVD Coatings — enhanced hardness and longer service life for high-shot tools.
- Passivation & Corrosion Protection — for sustained performance in humid molding environments.
Quality Assurance
All molds are produced under an ISO 9001 quality system with documented process controls. We perform DFM and mold-flow simulation prior to machining. Dimensional verifications use ZEISS CMM and 3D optical scanning; surface roughness is validated by profilometry. Each mold undergoes trial runs and first-article inspection (FAI) — including dimensional reports, shrinkage confirmation, visual surface checks, and functional tests for hinge fit, seal integrity (for overmolded cushions), and assembly. Tool life validation and maintenance schedules are supplied with production molds.
Our Factory
Our tooling department integrates high-precision 5-axis CNC centers, high-speed milling, mirror and conventional EDM, and wire-cut capabilities to produce complex cavities and core geometries. Robotic polishing cells and controlled polishing rooms deliver consistent mirror finishes. We operate dedicated mold trial presses with hot-runner test rigs, temperature-controlled platens, and automated part inspection systems. Supported by in-house CAD/CAM/CAE, mold-flow analysis, and an experienced tooling team, we deliver turnkey solutions from prototype to mass production.
