INDEPENDENT SOURCING PARTNER

Closed die forging manufacturer briefs, matched to factories

This desk is written for an OEM titanium medical forging buyer who already holds a cavity print, melt-source language, and a short production lot. Freeze the drawing revision, alloy, grain-flow direction, heat-treat condition, quantity, and US destination, then we route that packet to candidate closed-die plants. Closed Die Forging Manufacturer Sourcing does not own a press, a die shop, or ISO 13485; plant certificates stay with the mill that actually forges the heat.

Die impression and flash line on a closed-die forging

Preform yield against flash-land wear on a short run

On a medical titanium or alloy-steel cavity, a generous preform can fill the impression and still waste billet. A tighter preform can raise yield and then chew the flash land after a few hundred strokes. Ask each closed die forging manufacturer to state expected flash thickness, when a resink is priced, and whether a 50–500 piece lot even amortizes that wear. A low piece number that hides die rework is not a like-for-like factory wholesale quotation.

Heat-treat furnace load of forged parts with temperature chart

Keep hardness, melt source, and geometry on separate lines

Annealing, quenching, and tempering change HRC/HRB/HV readings and residual stress. Name the hardness window and whether shot peening or machining happens before or after heat treat. When the packet includes oem titanium medical forging service, add melt source, interstitial limits, and how ISO 13485 document mapping sits at the producing plant—not on this website.

CMM probe measuring a forged gear blank

Cut the FAI coupon from the same heat as production

A cousin heat or a tryout bar does not answer device-grade traceability. Ask the plant to cut the FAI coupon from the same heat as production, balloon the print for CMM, and say whether that coupon, the mill cert, and the hardness chart travel as one package. If the datum scheme cannot be probed after trim, FAI stalls regardless of a brochure Cpk number.

Documents to request from a candidate plant

None of the following is a credential of Closed Die Forging Manufacturer Sourcing. Each item applies to a named factory, process, and revision.

  • ISO 9001 quality manual excerpt placeholder

    ISO 9001 quality system evidence

    Ask for the certificate scope statement and whether closed-die forging and heat treatment sit inside that scope, not a sister machining plant.

  • IATF 16949 PPAP binder placeholder

    IATF 16949 and PPAP pack

    For automotive lots, request which PPAP level is included, whether dimensional FAI is in the piece price, and which special processes are outsourced.

  • AS9100D and NADCAP heat-treat file placeholder

    AS9100D / NADCAP special process files

    Heat treat, NDT, and shot peening may need NADCAP. Confirm the actual process, not a corporate logo on a homepage.

  • ISO 13485 medical forging documentation placeholder

    ISO 13485 mapping for medical titanium

    When the brief includes oem titanium medical forging service, ask the plant—not this desk—how device-grade traceability, cleanliness, and change control are evidenced.

Where buyers usually apply closed-die forgings

Use these verticals to name load case, inspection, and document set. Case counts are not published because this desk does not inventory completed programs.

Submit specifications to request factory wholesale quotations

Name product, quantity, destination, and the inspection basis—including whether an FAI coupon must come from the production heat. Eligibility for FREE sourcing support up to 3% applies to qualified business buyers and is confirmed after review of those fields.
