Capabilities.
Four companies. Six facilities. More than 310 machine tools, installed and on order. One integrated manufacturing platform.
Backed by more than 250 years of combined experience and a shared plan for growth, ASM delivers end-to-end manufacturing: milling, mill-turn, turning, grinding and EDM, supported by NADCAP special processes, assembly, metrology and engineering support. Components move from raw material to finished, coated and inspected assemblies without leaving the platform, giving customers one chain of quality custody, shorter lead times and a single point of accountability.

Integrated process chain.
Retaining special processes within the platform removes outside-processing transit and maintains a single chain of quality custody.
1. Lead time
Outside-processing transit is measured in weeks. Holding the accreditations that govern finishing, non-destructive testing and bonding within the platform takes those weeks out of the schedule.
2. Quality custody
Traceability is maintained at platform level from raw material through machining, finishing, inspection and delivery, under a single chain of accountability.
3. Rate readiness
At volume, every day of outside-processing transit represents schedule risk. Vertical integration is a prerequisite for sustaining rate during production ramp.
