How are titanium quality criteria and dimensional tolerance limits established for custom products?
For non-standard titanium cookware, titanium-teaware, drinkware, or outdoor accessories, precision quality criteria are finalized prior to mass production through a formal dual-engineering sign-off protocol.
Physical pre-production samples are thoroughly verified, sealed, and signed by engineering teams as the legally binding benchmark for visual finish, color hue, and fitment.
Multi-axis Coordinate Measuring Machine (CMM) inspection routes verify complex radii, wall thickness, and threading against client CAD files.
Standard wall thickness tolerances are controlled within ±0.03 mm for CNC-turned titanium hardware and ±0.05 mm for deep-drawn double-wall cookware and vacuum-insulated drinkware containers.
What is the standard procedure if a production batch exceeds the agreed inspection defect rate or AQL threshold?
If a delivered batch exceeds agreed Acceptable Quality Limit (AQL) statistical sampling parameters during receiving inspection, Mutian executes a structured 8D problem-solving procedure to eliminate non-conformance and safeguard delivery schedules.
- Immediate Batch Containment: Corresponding inventory lots and active factory production runs are quarantined within 12 hours of non-conformance notification.
- 8D Root Cause Analysis: Engineering logs, stamping pressure profiles, raw material heat profiles, and vacuum furnace parameters are systematically reviewed to identify defect origins.
- RMA & Priority Remanufacturing: Confirmed non-conforming items are priority-remanufactured at zero additional charge or credited toward future orders according to contractual agreements.
How do you differentiate acceptable natural titanium finish characteristics from actual surface defects?
Commercially pure titanium develops subtle micro-textures and natural grain shifts during vacuum annealing, sandblasting, and crystallization processes. To maintain objective receiving standards, Mutian provides physical visual limit boundary cards defining acceptable material characteristics versus rejectable imperfections.
Uniform micro-crystalline metallic sheen, consistent sandblasted matte texture (Ra 1.6 to 2.5 µm), and natural oxide grain transitions inherent to pure titanium.
Mechanical scratches exceeding 0.02 mm depth, surface oil pitting, inconsistent anodization color banding, tool gouges, or sharp burrs.
Are titanium material test reports (MTR) and food-grade compliance certificates provided for bulk orders?
Yes. Every production lot is directly matched to raw titanium ingot heat numbers. Upon request, Mutian issues detailed chemical composition analysis reports verified through optical emission spectrometry to confirm raw material purity (Commercially Pure Grade 1 / Grade 2 titanium).
For food-contact applications including titanium-drinkware, teaware, cookware, and tableware, products undergo heavy metal leaching testing aligned with FDA, LFGB, and GB food safety standards. Custom laboratory testing documentation is organized according to destination market customs requirements.
