In-House Silicone Secondary Operations
A molded part is rarely the finished product. Assembly, decoration, testing usually follow. Every handoff introduces latency, miscommunication, and quality drift, costs that rarely appear on a purchase order but show up in lead times and defect rates.
The most efficient manufacturers treat the part not as the end of the process, but as the beginning of a controlled, continuous workflow. That is why we keep secondary operations in-house. For silicone rubber components, we offer an integrated finishing suite designed to preserve the material's unique properties.
Secondary operations we support
Practical finishing and post-molding services for silicone rubber parts that need fit, function, identification, or assembly readiness.
Adhesives
Adhesive silicone gels and bonding support for programs that require strong chemical bonds to liquid silicone rubber or related substrates.
Cutting & Coiling
Repeatable tube cutting and automated coiling support for silicone tubing programs that need consistent length, handling, and packaging results.
Die Cutting
Die cutting transforms silicone parts into required shapes, patterns, and openings. We also support hole punching, Y-slit, X-slit, and other slit configurations.
Post-Curing
Controlled elevated-temperature post-curing can improve mechanical properties, heat resistance, and biocompatibility-related production requirements.
Pad Printing
Pad printing adds markings, icons, logos, or visual indicators to molded silicone parts where product identification or user-facing aesthetics matter.
Functional Testing
Final checks confirm that assemblies and molded parts meet intended use requirements before packaging or shipment.
Slitting
Customized slitting stations support consistent slits in valves, bottle nipples, and other LSR components that require precise openings.
Laser Marking
Laser marking can add product identifiers, serial numbers, tracking marks, or durable part information to liquid silicone rubber components.
Post Vulcanization
Post Vulcanization is a controlled secondary heat treatment used after silicone molding. By exposing parts to elevated temperature for a defined time, the process helps complete cure behavior, reduce residual volatiles, stabilize mechanical performance, and support applications with stricter medical, food-contact, or long-term reliability requirements.
Upstream molding processes before secondary operations
Secondary operations begin with a molded or extruded silicone part. Explore the manufacturing routes that often feed into finishing, assembly, testing, and packaging work.
LSR
LSR Molding
Liquid silicone rubber molding for tight-tolerance, repeatable silicone parts that may need trimming, post curing, inspection, or assembly.
CMCompression Molding
Compression molded silicone parts often move into finishing work for flash removal, surface treatment, inspection, and packaging.
EXTSilicone Extrusion
Extruded silicone tubing and profiles can be cut, joined, marked, inspected, and prepared for customer-specific assemblies.
OVMLSR Overmolding
Overmolded components may require bonding review, functional checks, secondary assembly, and final quality control before release.
Applications for silicone secondary operations
Useful when molded silicone parts need additional function, assembly readiness, or product identification.
Medical & Healthcare
Device subassemblies, functional checks, post-curing, identifiers, and controlled silicone openings.
Baby Care & Food Contact
Bottle nipples, valves, tubing, dispensing features, slit patterns, and packaging preparation.
Consumer & Electronics
Printed icons, tactile details, soft-touch components, buttons, seals, and decorative silicone parts.
Industrial Programs
Gaskets, tubes, protective parts, serial marking, final testing, and production-ready finishing.
