Injection Molding and Assembly for Performance-Critical Devices
Viant Fremont is known for supporting medical device programs that require precise molding, disciplined processes, and steady execution. The site has long served surgical, interventional, diagnostic, and laboratory technologies where part performance and consistency are non-negotiable.
The site centers on insert molding, overmolding, and high-temperature materials, produced across 30 presses operating 24/7 in cleanroom and controlled environments. Continuous monitoring and on-site tooling support help maintain process control and throughput.
Located next to Viant’s Fremont Design & Development center, it puts design engineers and the production floor within walking distance of each other. A molding or tooling issue can go straight back to the team that built the process, keeping the loop between a change and a validated fix short as a program scales toward higher volume.

| Core Capabilities | Our Approach | What it Means For You |
|---|---|---|
| Molding & Overmolding | Complex, precision medical device injection molding using 30 presses (high-mix / low-volume), including horizontal and vertical presses, insert molding, overmolding, and high-temperature materials. Class 8 cleanroom and white-room molding support parts that must meet strict cleanliness and performance requirements. | Reliable, repeatable molded components with the geometries, materials, and cleanliness levels your devices require without needing multiple molding suppliers. |
| Assembly & Finished Device Services | Sub-assembly and finished device assembly, including mechanical and electromechanical builds, microscope assembly, ultrasonic welding, heat staking and adhesive bonding, plus finished-goods assembly that can be sterile packed. | A single partner to mold, assemble, and integrate components, reducing handoffs, logistics risk, and launch complexity. |
| Secondary Processes & Machining | Functional testing, pad printing (multi-color), plasma treatment, and CNC machining of plastic components, supported by an onsite tool room for mold maintenance and repair. | Components and assemblies leave Fremont ready for downstream integration, with tooling and processes kept in tune to protect quality and uptime. |
| Packaging & Sterilization Support | Non-sterile and sterile-barrier packaging (including tray sealing), plus an in-house packaging test lab for peel tests and dye-penetrant evaluations. Sterilization management supported through strong regional resources. | Your packaging is developed and verified to protect product integrity with test data and sterilization coordination handled alongside manufacturing. |
| Quality, Regulatory & Compliance | FDA-registered, ISO 13485 certified, and cGMP-compliant with a proven track record of successful audits and a focus on building quality into the process. | Audit-ready documentation, stable processes, and confidence that parts meet regulatory expectations for medical and pharma use. |
