Each bar arrives with its mill certificate, checked against the grade and heat number on your drawing before cutting. Traceability runs from raw material to finished pin.
The first pin off the machine is measured on the CMM, mating diameter included, and the FAI report is sent to you. Series production is released on your sign-off.
Operators pull pins during the run and check them to an AQL plan, which flags diameter drift while the lot is still being cut.
Every lot gets a 100% dimensional and visual check, with CMM and optical measurement available for critical diameters. The inspection record and material certificate travel with the packed pins.
Each sector's pins and terminals are made to your drawing, using the features you specify: cross holes, flats, knurling, grooves or laser marking.
Questions on specs, lots and files. Send a drawing and we reply within one business day.
Ask a QuestionScrew-machined contacts suit pins with cross holes, knurls, grooves or a mating diameter that must repeat tightly. Stamped and formed contacts suit bent flat contacts at very high volume. We make machined contacts to your print.
Diameters hold ±0.005 mm when ground and ±0.01 mm when turned. Surface finish is Ra 1.6 µm as standard and Ra 0.4 µm on request. See machining tolerances for how to call them out.
You can order a single piece. Fast-track prototypes ship in 3 days and standard prototype lots in 2–3 weeks. Series production usually takes 4–6 weeks, with rush dates quoted job by job.
Base metals include brass C36000 and C37700, copper and stainless steel. Plating options are nickel, electroless nickel, tin, copper, chrome and zinc. Any other specification on your drawing is confirmed in the quote.
A STEP or IGES model plus a 2D drawing with GD&T is ideal. SolidWorks, ProE, PDF and DWG files also work. An NDA is available on request before you share anything.
Every lot ships with a material certificate and an inspection record, and an FAI report is issued before production starts. FAI and PPAP packages are available on request. Parts are made under an ISO 9001:2015 quality system with full traceability.
