Description
Our Custom High Standard S136/420 Silicone Injection Mold Tooling for Household Silicone Square Shower Mats is engineered to achieve superior durability, precision, and surface quality for large-area consumer silicone products. Manufactured from premium tool steels—S136 and 420 stainless steel—these molds offer excellent corrosion resistance, hardness, and polishability, ensuring long service life even under high-volume silicone injection cycles.
By combining 5-axis CNC machining, mirror EDM, and high-precision wire cutting, our molds deliver micron-level accuracy across wide cavity areas—critical for producing consistent, defect-free silicone shower mats with anti-slip textures, drainage channels, and uniform thickness. Designed with hot or cold runner systems, optimized gating, and advanced Moldflow analysis, our tooling guarantees efficient filling, minimal flash, and stable cycle times.
As your trusted OEM tooling partner, we provide a full turnkey solution—from rapid prototyping and mold validation to mass production support—helping you launch high-performance silicone shower mat products that meet the strictest quality and hygiene standards.

Production Process
- Material Selection & Compliance
S136/420 stainless steel selected for excellent wear resistance, polishability, and anti-rust performance. LSR grades chosen per FDA and LFGB food-contact compliance. - Precision Mold Design
CAD/CAM-driven tooling design optimized for large square cavities, drainage channel geometry, and anti-slip textures. Moldflow analysis ensures balanced filling and minimal cycle time. - Prototype Validation
Pilot runs confirm dimensional stability, flatness, and texture replication. Measured with CMM and 3D laser scanners to ensure uniform thickness across large areas. - High-Tolerance Mold Manufacturing
5-axis CNC machining, mirror EDM, and wire cutting create precise cavities and ejector systems. Polishing achieves mirror-grade finish for easy demolding of large silicone sheets. - Injection Molding & Post-Processing
Silicone shower mats molded under controlled injection parameters. Post-processing includes edge trimming, surface finishing, and laser engraving for custom branding. - Quality Assurance & Durability Testing
Dimensional accuracy verified with CMM; tensile, compression, and tear resistance tests performed on molded parts. Anti-slip performance and drainage effectiveness validated through simulation testing. - Traceability & Packaging
Full ISO documentation and lot traceability. Molds shipped in protective wooden crates with anti-rust coating and detailed technical reports.
Quality Control
Quality control for silicone shower mat injection mold tooling emphasizes long-term durability, surface quality, and dimensional accuracy across large product areas. All mold steel (S136/420) is verified for hardness and purity before machining. During production, in-line cavity pressure sensors, optical comparators, and 3D metrology systems ensure repeatability. Molded parts undergo slip-resistance testing, compression strength verification, and accelerated aging simulation to confirm performance. Our facility is ISO 9001 and IATF 16949 certified, with FDA and LFGB compliance for all silicone-contact applications.
