Four things decide whether a tube program ships on time: drawing completeness, material release, tooling readiness, and first article inspection cycles. TEC targets three weeks or less on OEM exhaust systems as a documented operational target. If a supplier's quoted lead time keeps slipping in production, one of those four is uncontrolled.

OEM tube manufacturing lead time depends on drawing completeness, material release, tooling readiness, and inspection cycles. See what TEC controls.

Switching your tube bending supplier is simpler than most teams expect. You send a drawing package, name one point of contact, and pick a date. TEC handles the rest: capability review, CNC programming, tooling, the prototype build, first article inspection, and material certification. Your current supplier keeps shipping the whole time, so nothing on your line changes until the new parts are proven. The post covers what you send, what TEC handles, and what a prototype order actually costs.

A tube prototype proves a part is possible. It does not prove the part is repeatable. The variables a prototype freezes, material lot, tooling wear, bend speed, and fixturing, are exactly the ones that drift at production volume. Our new post breaks down why prototypes pass and production runs fail, and how to catch the gap at quote review instead of on the line.

A tube prototype can pass approval and still fail at production scale. Here is why the gap happens and how OEMs catch it before the first run.

Thin-wall tube bending: ovality above 7% and wall thinning above 12.5% are both OEM inspection failures.

Both come from the same place - mandrel selection, tooling setup, and bend speed that haven't been validated for the material and bend radius you're running. New post on what actually controls these variables and how process documentation prevents them from reaching the OEM.

Thin-wall tube bending ovality control: how CNC mandrel bending holds ovality under 7% and wall thinning under 12.5% for OEM fit.

Tube bending tolerances: ±1° angle and ±1/16″ length. Two numbers that determine whether a tube passes OEM incoming inspection.

In a multi-bend assembly, angle error compounds across every bend. A part can be within spec at each individual bend and still fail fit check at assembly. That's why documented process control matters more than individual operator skill. New post on what these tolerances control in practice - and what happens when they drift.

Tube bending tolerances define whether a fabricated part will function inside a larger OEM assembly. Two numbers determine qualification at TEC: ±1° angle tolerance and ±1/16" length tolerance. These are not aspirational targets - they are documented, repeatable minimums held across every part in...

CNC vs. manual tube bending. For OEM production, it's about process control - not just the machine.

A CNC program holds +-1 degree and +-1/16" tolerances across every part in every run. Manual bending holds them when the right operator is running the machine.

New post on why that difference matters for OEM programs.

Small geometric drift creates downstream disruption.

±1° angular accuracy and ±1/16″ length tolerance help protect fit and weld alignment across runs.

When inspection happens only at final shipment, correction cost increases.

Low-volume orders still require production-level control. See how OEMs protect short-run tube bending projects from repeatability issues.
