Digital Manufacturing

Swiftly move from prototype to production

Your prototype is final. It’s time to provide a roadmap for how it will be built in the factory. Define, visualize, and automate complex processes in ION so technicians know exactly what they need to do. Add custom fields at any procedure step where technicians can add values like torque, gap, weight, and voltage with backend workflows based on deviations from approved ranges.

Go To Step 2



Unload incoming shipments

Your parts have arrived and are ready for inspection, which you'll add to ION so you can track them as they move through the factory.

Back To Step 1Go To Step 3



Examine and verify parts

Inspect incoming parts and record in ION. Capture key information like serial numbers and other traceability attributes. Create issues against any received inventory that is not as expected to track supplier quality.

Back To Step 2Go To Step 4



Manage raw materials and parts

Move parts to inventory and assign them barcodes so they can be tracked in ION across the entire product journey for advanced traceability. ION tracks consumption and allocation of parts to other assemblies. Submit inventory requests for an assembly kit in one click.

Create a production schedule

Plan production with constraint-based scheduling and predictive data. Enter the desired customer delivery date and ION will create a target schedule for building, testing, assembling, and ordering based on historical logs and inputs.

Cell Based Assembly

Track production processes

Ready to start building! Technicians follow step-by-step visual work instructions in ION. Every step is timed so you know exactly how long it takes to build a product. When there’s an issue, technicians can alert an engineer in real-time at the exact step where they encountered it – and an engineer can respond immediately.

Step 7

Assemble parts

ION also supports assembly line production.

Step 8

Identify and address quality issues

Assembly is complete and now it needs to be approved. Identify non-conformances and disposition for further actions.

Step 9
Go Back



Prepare product for shipping

It’s time to ship final products to the customer. ION’s living digital thread provides traceability across the entire product lifecycle including maintenance and repair.

Setting the Gold Standard in Manufacturing Security and Compliance

At the core of the manufacturing industries we support lies a critical need for compliance with intricate regulations and unwavering data privacy standards. Whether we’re working with an aerospace company with defense contracts, a medical device manufacturer pioneering breakthrough advancements, or an emerging climate tech leader, safeguarding highly sensitive information is crucial for their continued success. That’s why we’ve designed ION Factory OS to support a seamless flow of sensitive production data that ensures not only regulatory adherence but also the safeguarding of highly confidential information and intellectual property. 

To deliver on our promise of exceptional security in our manufacturing software, our solutions are deployed in GovCloud environments for maximum compliance and reliability. Our software is also deployed in FedRAMP environments, reflecting our commitment to meeting rigorous government security requirements. 

We maintain SOC 2 certification and adhere to ITAR regulations, ensuring stringent data security and privacy standards. This blend of certifications and deployments is the reason we’re the choice of fast-growing hard-tech innovators with complex compliance requirements.

ION Factory OS

Discrete complex manufacturing teams use ION Factory OS to build, iterate, and track changes from prototype through production. As you build with ION, your team is visually guided through step-by-step processes, capturing in-process data and redlines so that issues can be surfaced and fixed the moment they happen. Highly configurable, with an open API for turnkey integrations that connect all your factory floor systems, ION is designed to get you up and running fast without expensive, lengthy implementations.
