Biocompatible Silicone Gel Positioning Pad for Surgical Tables
Challenge · Solution · Result
Medical equipment manufacturer required a surgical table positioning pad with FDA-cleared silicone gel top layer, consistent 25mmHg interface pressure across all sizes, and autoclave sterilization compatibility.
Laminated construction: compression-formed silicone gel layer (30A) over closed-cell PE foam substrate. All adhesive bonds tested to ISO 10993-5 cytotoxicity. Validated autoclave resistance at 134°C / 30 cycles.
Interface pressure 22–28mmHg (target 25mmHg ± 15%). Passed ISO 10993 cytotoxicity and sensitization. Maintained dimensional integrity through 200+ autoclave cycles.
Engineering Insights
DFM Analysis & Process Optimization
DFM Analysis: Edge trim profile designed to prevent gel layer delamination at perimeter — identified in initial 5-piece prototype testing and corrected before tooling.
Our engineers work from your CAD drawings before any tooling begins — identifying potential failure modes, proposing material alternatives, and validating gate/cooling layouts digitally. This eliminates costly mold revision cycles.
