Procurement Problems

Do You Have These Troubles Buying CNC Machining Parts?

Most of these are coordination failures rather than manufacturing problems. Here is how each one is handled here.

The design is not reasonable and needs rework?

Professional analysis, evaluation and verification of manufacturing feasibility before tooling.

Does it take a lot of effort to produce the drawings?

No need for professional engineering 3D drawings. A sketch with dimensions is enough to start.

Is the quality uneven between batches?

Strict quality management with 100% inspection from raw material through to finished goods.

Is the quotation period too long?

Specialised personnel, specialised service, specialised quotation. Reply within 2 working hours.

Can the delivery date be guaranteed?

Information-based production management with controllable, visible progress.

Client Feedback

Industries We Serve With CNC Machining

“This factory delivers high-quality automotive parts on time with excellent precision. Pengfeng Precision is a reliable long-term partner for us.”

MK Mark KellerFrom the automotive industry

“We audited them for supplier qualification and the documentation was cleaner than our Tier 1 vendors. That is rare at this price point.”

DL David LinFrom the medical device industry

“Prototyping one piece and producing fifty thousand from the same drawing — with the same tooling — is why we stopped shopping around.”

JP Jonas WeberFrom industrial robotics
FAQ

Common Questions About CNC Machining

How is the cost of custom manufacturing calculated?

Cost is material plus tooling (if any) plus processing time plus finishing, quoted as one line-item breakdown. Tooling is a one-off; repeat orders in the same part drop to the unit price alone.

How long does it take from design to delivery?

Prototypes take 3–5 days. Standard production is 7–15 days depending on volume and finishing. Anodizing and powder coating add 2–4 days because they are batch processes.

What is your quality assurance promise?

Any batch failing our own acceptance criteria is replaced or reworked at our expense before it ships. Every shipment carries a dimensional report and material certificates.

Can you sign an NDA before seeing my drawings?

Yes. We sign mutual NDAs before file review and will hold tooling exclusively for your part with your name stamped on it.

What file formats do you accept?

STEP, STP, DWG, DXF, IGES, IGS, PDF, and images. A sketch with the key dimensions and tolerance is enough to start — engineering drawings are not required.

Our Quality Commitment

Any batch that fails our own acceptance criteria is replaced or reworked at our expense before it ships — not after you complain. Every order carries a dimensional report and EN10204 3.1 material certificates as standard.
