IQC
Materials and related documents are checked against the agreed program requirements before production starts.
Testing & Inspection
Four quality gates, in-house inspection control, and partner-lab coordination when extra validation is required.
Inspection Route
Inspection stays connected to the program, not bolted on at the end
The testing route is meant to show how SIKING checks incoming materials, process stability, finished parts, and outgoing shipments before release. It also clarifies where partner labs sit when extra program-specific validation is needed.
- Core dimensional, hardness, and visual checks are handled in-house
- Inspection records can be aligned to the buyer review package
- Partner labs are coordinated when extra external validation is required
Inspection Sequence
Four checks, one release discipline
The quality route follows the same order on every program: incoming material review, in-process checks, finished-part review, and outgoing confirmation before shipment.
That sequence matters because it tells buyers where to place their own qualification checkpoints without relying on vague process language.
IPQC
First articles, critical dimensions, and process stability are monitored during manufacture.
FQC
Finished parts are checked for dimensional, visual, and order-specific release requirements.
OQC
Shipment release confirms quantity, packaging, and required documentation before dispatch.
Who Handles What
In-house checks first, partner labs when the program needs more
Core inspection is kept in-house. External validation is coordinated when buyer or application requirements ask for it.
IN
In-house inspection
Dimensional checks, hardness checks, visual inspection, and routine production monitoring are handled within the in-house quality route.
EX
Partner lab coordination
Application-specific external validation can be coordinated when the qualification package needs extra third-party support.
DOC
Buyer review package
Inspection records, agreed checkpoints, and related qualification documents can be aligned with the order review package.

Important boundary
This route explains inspection and coordination. It does not add new held certifications or imply blanket external lab approvals.

Use the quote route to raise testing expectations during qualification, or review the certifications page if your team needs the current held-system baseline first.
