Wedge Anchor Forming with Split Die Tooling – One Shot, No Turning
Wedge anchors formed in one shot by split die tooling on a 134LL multi-station cold former, eliminating taper-end turning and keeping grain flow through the expansion cone.
Split Die Cold Forming – Tooling for Parts a Solid Die Cannot Release
Split die cold forming tooling for parts a solid die cannot release - collars, undercuts and overhangs. Two to four segments, patented, in production since 2008.
Automotive Muffler Bolts – One-Piece Cold Heading Die, Split Die at Station Four
Automotive muffler bolts formed in one piece in 2008 on a 134L cold heading machine, with a split die at the fourth station - the project that shaped how BENC MOULD develops cold heading dies.
Automotive Non-Standard Fasteners – Custom Cold Heading Die Development
Custom cold heading die development for automotive non-standard fasteners - split dies, special-shaped punch pins and full process development from drawing to stable production.
Hollow tube screw
Hollow tube screw One-shot forming using multi-station cold headers (screw cold header 104‑106,134L‑137L,164‑166L or nut cold header), minimizing turning & drilling work. For hollow…

Cold Heading Die Materials: Carbide vs HSS vs PM Steel
Choosing a cold heading die material is one of the few decisions that locks in everything downstream: hit rate, tolerance drift, regrind interval and…
Cold Heading Die Precision: What G4 to G9 Really Means
A die print says G6. Most buyers cannot translate that into what actually arrives in the box, and most suppliers will not explain it,…
Extrusion Ratio in Cold Heading: Safe Limits and Die Design
The extrusion ratio is the single number that decides whether a shank reduction can be formed in one blow, needs two, or cannot be…
