Three CMMs measure every lot to the control plan. The report ships with the parts, unasked.
Twelve engineers review your drawing and flag cost-down options that keep the spec, before we quote.
No sub-tier suppliers. We control the schedule and quality across the whole line — 98.6% on-time delivery.
PSW, FMEA, control plan, MSA and material certs ship with the sample so approval takes one round.
Every programme has its own control plan. Gauges are calibrated every 6 months and test records are kept for 15 years per IATF.
Programmes through PPAP and in serial production
Tier-1 suppliers on three continents keep programmes with AXLEON for 6.4 years on average
98.6% on-time delivery in 2025 · customer-detected defects ≤ 25 PPM · 14 customer audits, all passed
Attach 2D/3D files (STEP, DWG, PDF), material, annual volume and required standards. Our engineers reply with design notes and piece price.
