Frequently Asked Questions
Get answers to common questions about our liquid silicone rubber molding services, processes, and capabilities.
Prototypes typically take 5-10 business days, tooling development ranges from 3-6 weeks, and production runs can begin within 1-2 weeks after tool approval.
We routinely achieve tolerances of ±0.005″ for most features, with critical dimensions held to ±0.001″ when required.
Our engineering team provides Design for Manufacturing (DFM) analysis to optimize your parts for LSR molding. We review wall thickness, draft angles, undercuts, and parting lines to ensure manufacturability and cost-effectiveness.
Yes, LSR parts can be sterilized using various methods including steam autoclave, gamma radiation, ethylene oxide (EtO), and electron beam sterilization. We select materials and design features to ensure compatibility with your required sterilization method.
We accept most common CAD file formats including STEP, IGES, STL, SolidWorks, AutoCAD, and Inventor files. 3D models are preferred, but we can also work from 2D drawings with detailed specifications.
