10. In-depth Q&A (FAQ) for Procurement Managers

Q1: How do you verify material authenticity for aerospace and medical applications?
Every batch of incoming material undergoes strict verification. We require Mill Test Reports (MTR) from source suppliers, verifying chemical composition and physical properties. For high-reliability parts, we use Positive Material Identification (PMI) and spectrographic analysis to confirm alloys match your specifications (e.g., 17-4PH or 316L) prior to machining.
Q2: What is the optimal process for requesting an accurate RFQ quote?
For a precise, prompt quotation, we recommend submitting a comprehensive engineering package containing 3D CAD files (STEP, IGS, or Parasolid format) for geometry, along with 2D drawings (PDF or DWG format) that define tolerances, thread dimensions, surface finishes, and quality requirements. Please specify the alloy grade, production quantities, shipping destinations, and any post-processing requirements.
Q3: How does PFT handle project changes when a drawing is modified mid-production?
We follow strict engineering change order (ECO) protocols. When a drawing is updated, our engineering team halts the active machine setup, verifies CAD file variations, evaluates the impact on stock materials, and updates the CNC program. We provide a modified quote for any differences in setup time or tooling, and resume production once the change is approved.
Q4: What is the typical lead time for complex multi-axis prototypes vs. production runs?
Rapid prototype components typically ship within 1 to 3 days depending on complexity and surface finishing. Standard production runs (e.g., 1,000 to 10,000 pieces) average 7 to 14 days from final design approval to quality release. We also offer expedited lanes for critical projects.
Q5: Can you machine and finish biocompatible medical devices?
Yes. Our facility is certified to ISO 13485:2016 for medical device manufacturing. We work with biocompatible materials such as PEEK, titanium, and medical-grade 316L stainless steel. We follow clean handling practices to prevent cross-contamination, use specialized cooling liquids, and offer passivation and clean-room packaging services.
Q6: What is your process for quality assurance and handling discrepancies?
We run inspections at several stages: incoming material verification, first-article inspection (FAI) for each setup, in-process sampling, and a final 100% inspection on critical dimensions before shipment. If a discrepancy is identified, our QA team initiates a corrective and preventive action (CAPA) process to trace the root cause, adapt tooling, and secure replacements quickly.
Q7: Can you assist with the design of components that are not yet fully engineered?
Yes, our engineering team provides Design for Manufacturability (DFM) reviews. If you submit sketches, concept files, or physical parts, we can help build the required 3D CAD files. We analyze geometries to find ways to reduce cycle times, minimize setup changes, and lower overall production costs.
