Quality and Precision
We refine every detail to ensure extraordinary quality at every stage
Incoming Inspection
Our automated incoming inspection streamlines the design throughput, ensuring industry-leading quality with 100% part verification. Fast issue reporting links directly to suppliers, keeping everything compliant, efficient, and launch-ready.
Emitter Production
The core component of Enpulsion’s IFM technology, our emitters are precision-crafted from incoming parts. Advanced parallel batch manufacturing with synchronized inspections ensures efficiency, consistency, and seamless production flow.
Propellant Loading
Next, we load each emitter with propellant, following the same high-efficiency scaling approach, using a precise vacuum process to ensure optimal performance while maintaining seamless production flow.
Emitter Characterization
In this step, semi-finished emitters undergo an initial characterization in vacuum facilities. We use batch testing and automated scripts to streamline the process, reducing chamber evacuation times and maximizing efficiency.
Scanning & Pre-Selection
We use advanced topology scanning to characterize emitters, leveraging predictive statistical models that optimize selection and quickly identify emitters that fall short of our rigorous performance standards.
Final Assembly
Selected emitters and preassembled components are stored, ready for final thruster assembly. Customer-driven configuration kicks off a rapid, Kanban-based process, which produces fully assembled thrusters in just hours.
Thermal Acceptance Testing
After final assembly, thrusters undergo rigorous acceptance testing, which incorporates mission-specific conditions provided by the customer. Batch testing ensures efficiency without compromising timelines or precision.
Vibration Testing
Assembled thrusters undergo vibration testing, conducted in parallel with thermal acceptance testing to maximize efficiency while ensuring they meet our established performance standards.
Functional Acceptance
Thrusters undergo final functional firing tests in vacuum facilities, with digitalized reporting and agile workflows ensuring swift decisions and rapid replacement for major non-conformances.
Final Inspection & Shipping
Final inspection, packaging, and shipping follow a streamlined, flexible process optimized based on customer input. Close collaboration with our logistics partners enables fast turnaround and timely delivery.
Industrial Capabilities
Our propulsion technology delivers dynamic thrust control and adaptable specific impulse — expanding the possibilities of satellite mobility through expert innovation.
