Custom Food Grade Silicone Parts Built for Production
LSRParts delivers precision food grade silicone parts engineered specifically for demanding food, beverage, and baby-care applications.
Our liquid silicone rubber (LSR) injection molding, compression molding, and extrusion capabilities ensure dimensional consistency, sealing performance, and full regulatory compliance in every component.
From DFM Reviews to Mass Production
From early DFM reviews through mass production, we support OEMs and product developers with custom drawings and 3D files, turning complex requirements into reliable, production-ready parts.
Thorough Engineering Review
Our engineering team conducts full DFM reviews covering part geometry, wall thickness, sealing features, draft, undercuts, flash requirements, material hardness, shrinkage, tolerance, bonding requirements, and expected production volume.
