1. Core basic information
Part name and purpose: Briefly explain what this part is and where it is used (for example: UAV structural parts, medical bone implants, chemical pump valve impellers).This helps manufacturers understand their functional importance and potential technical requirements.
Demand quantity：
Sample pieces (1-10 pieces)
Small batches (dozens to hundreds of pieces)
Large quantities (more than a thousand pieces)
2. Technical documents
This is the core part, and it is recommended to provide it.
Two-dimensional engineering drawing：
Clear dimensions and tolerances: including all linear dimensions, angles, thread specifications, etc.
Geometric tolerances (GD&T): such as straightness, flatness, roundness, position, concentricity, etc.This is especially important for high-precision assemblies.
Surface roughness: Indicate the Ra or Rz values of each key mating surface.
Technical requirements: such as non-marked tolerance standards, deburring requirements, sharp edge chamfering, etc.
Benchmark: Clearly mark the design benchmark and measurement benchmark.
3D model file：
Provide common formats such as STEP, IGS, X_T, etc. to facilitate direct programming and process analysis by manufacturers.
Ensure that the three-dimensional model is consistent with the two-dimensional drawing information.
3. Material and process details
Titanium alloy grade：
Must be clearly specified, for example: TC4 (Ti-6Al-4V, Gr5), TA2 (Gr2), TB6, TC21, etc.The mechanical properties, processability and prices of different grades vary greatly.
If there are special requirements, such as the use of imported materials or aviation-grade bar materials, it must be specified.
Material status：
For example: annealed state, solid solution state, etc.This affects the processability of the material and the mechanical properties of the parts.
Heat treatment requirements：
Do you need solution aging treatment, annealing, etc.?What performance standards (such as tensile strength and yield strength) need to be met?
Surface treatment requirements：
Common surface treatments for titanium alloys include：
Anodizing: Different colors (such as gold and blue) can be produced for marking or wear resistance.
Sandblasting: Obtain a uniform matt surface.
Polishing: To achieve a mirror surface or a specific finish.
Coating: such as chrome plating and nickel plating (note that special activation treatment is required before titanium alloy plating).
Laser marking.
4. Quality and inspection requirements
Key characteristics: Specify which dimensions or characteristics must be strictly controlled.
Inspection standards and tools：
For example: use a three-coordinate measuring machine (CMM), an optical projector, a caliper, a micrometer, etc.
Do I need to provide a full-size inspection report (FAI)?
Non-destructive testing requirements：
Penetration testing (PT): Check for surface defects.
Ray inspection (RT): Check for internal defects.
Ultrasonic testing (UT): Check for internal defects and material consistency.
Third-party certification: Does the product need to meet specific industry standards (such as aerospace AS9100, medical device ISO13485, automotive IATF16949)?Do I need to provide a material warranty (MTC/CofC)?
5. Logistics and business information
Target unit price/budget: If you have a budget, you can provide a range, which helps manufacturers seek optimization in the process.
Delivery cycle: The expected sample delivery time and mass production cycle.
Packaging requirements: Are there any special packaging requirements for anti-rust and anti-collision?
Place of delivery.
The more professional and complete the information provided, the more accurate the quotation obtained, and the smoother the cooperation process. For titanium alloy, a difficult-to-process and high-cost material, full communication in the early stage is a better way to avoid “pits”.
