One project engineer owns your part from first quote to repeat orders, so nothing gets lost between departments.
Engineer checks tolerances, material and finish against your 2D/3D files.
Within 24 hItemised price, tooling cost and suggestions that reduce cost without changing fit.
Within 48 h5–50 samples on production machines, not a separate prototype shop.
7–12 daysFull dimensional report, material certs and PPAP level 3 on request.
IncludedSPC on critical features, weekly progress photos and inspection data.
14–30 daysVCI film, fumigation-free crates, consolidated sea or air freight.
FOB JiangbeiCustomer names are withheld under NDA. Figures are from production records.
Replaced a European supplier on 14 part numbers. Moved from shaping to grinding to hit DIN 6 and lowered noise by 4 dB.
4-axis HMC cells with in-process probing. Every body hydro-tested and marked with a traceable heat number.
Took over casting and machining in one site, cutting the customer's supply chain from three vendors to one.
“We audited Kestrel before moving our spline shafts. Their CMM data matched our incoming inspection to within two microns. Three years in, we still have not opened a quality claim.”
“Quotes come back in two days with real DFM comments. One change to a fillet radius saved us 11% on a flange.”
“Weekly photos and inspection sheets mean I know where my order is without chasing anyone.”
Bring drawings: our engineers will quote on the stand and show live gear-measurement reports.
Adds 60,000 milling hours a year and dedicated lights-out cells for aluminium housings.
How closed-loop probing and thermal compensation lifted capability on our tightest diameter.
