Tracebility
All new or revised products manufactured at YT undergo a structured and preventive quality planning process. Based on the quality plan level, the following activities are performed:
- PPAP (Production Part Approval Process)
- Warrants
- ISIR (Initial Sample Inspection Reports
- Balloon Prints
- FAS (First Article Samples)
- Flow Charts
- Control Plans
- FMEA (FAILURE Modes and Effects Analysis)
- Gage R&R (Gage Repeatability and Reproducibility
- Capability Studies
Inspection
Quality is our top concern.All the quality controls are carried out in-house.
All parts are operator inspected at each step in the production process with a final inspection of forging tolerances for near net shape forgings and finished part inspections upon completion of secondary operations. At YT, our QA process assures that all customer requirements are achieved prior to shipping.
The pictures at right are some major inspection equipment that YT uses a lot.
