Titanium Machined Parts Quality Control Checklist for Engineering Procurement Teams: the 2026 production season Guide No.1254

The titanium machined parts market in the Czech Republic rewards buyers who issue a complete drawing package, because an incomplete specification is the single biggest cause of quotation delay. The points below are drawn from everyday titanium machined parts programmes and are written for Engineering Procurement Teams placing orders in the 2026 production season.

From the Machine Shop to Your Dock

Confirm who arranges the export documents and the certificate of origin, because that task is often assumed by both sides. Cartons for titanium machined parts should be specified with the board grade, the internal packing method and a drop-test requirement. Insist on moisture protection and, where required, vacuum packing, because damp cartons are a common cause of claims. For high-value parts, agree the packing layout so that no two machined surfaces touch in transit.

Choosing the Right Material

The grade 5 (Ti-6Al-4V) titanium sets the achievable tolerance, the surface finish and the tool life, so it is the first item to write into the specification. The capability buyers pay for is high strength at low weight, and it comes from the grade 5 (Ti-6Al-4V) titanium combined with a controlled process. Cheap substitutes usually appear in the material grade and the finishing step, so inspect those areas first. A good titanium machined part starts with the grade 5 (Ti-6Al-4V) titanium, so agree the grade, the temper and the certificate before you discuss price.

Finding a Reliable Machine Shop

Ask the shop how many machines run titanium machined parts and whether your order shares a machine with another customer. Look at how the shop stores material and tooling; housekeeping on the floor is a reliable predictor of process discipline. Request the process plan and the inspection plan before you pay the deposit, so you can see how the part will be made and measured.

Quality Control and Inspection

Book a first article inspection before the run is released, and require the report to list every dimension against the drawing. Track the reject rate by characteristic rather than only in total, so you can see whether the process is drifting. Agree the sampling plan and the inspection level in writing, so acceptance is a calculation rather than an opinion.

Where the Price Actually Comes From

Ask for a cost breakdown by operation; it turns a price argument into a process conversation. Setup cost is spread across the batch, so a small batch carries a disproportionate share of programming and tooling time. Freight, duty and inland handling can add more than the unit price difference, so compare landed cost rather than ex-works price. Ask what the price would be at double the quantity; the answer shows you how much of the quotation is fixed cost.

Certifications and Compliance

For the Czech Republic, check the rules on restricted substances, packaging materials and marking before the parts are boxed. Request material certificates, dimensional reports and, where relevant, first article inspection reports with the shipment. Surface treatments and coatings carry their own documentation, so keep the process certificates on file for the programme.

What to Confirm Before Releasing the Order

Release the drawing, approve the first article, book the inspection, lock the packing and prepare the paperwork. Five steps, and the programme runs smoothly.
