Make the mold more intelligent
BenC mold Split Dies is the first multi-station molding mold developed by BenC mold in 20 years, and applied for patent technology property rights in 2013, which specially solves the problem of special-shaped fastener molding that the conventional integral main mold can not be demoulded. After years of research and development experience, the multi-petal mold petal Split Dies clearance has been optimized, the Split Dies is stable and smooth under high-speed continuous production, and it is impact-resistant and not easy to collapse. It supports the customization of 2-piece, 3-piece, 4-piece and other multi-cavity opening and closing dies according to drawings/samples, adapts to multi-station cold heading equipment of various brands, and is widely used for mass production of hollow rivets, sleeves, flange screws and eccentric special-shaped parts. BenC mold is the development of cold heading non-standard mold. The opening and closing mold belongs to the split combined mold, which relies on the opening and closing of the mold to achieve radial forming and automatic demoulding. It is the core mold for the production of fasteners with complex shapes. The common integral die can not be demoulded directly for the parts with special-shaped outer contour, large flange and hollow sleeve; the open-close die is formed by closed extrusion of a multi-petal die core, and the material is automatically opened and stripped after forming, so that a large number of secondary machining processes are omitted.
- Direct forming on cold header
- No need of secondary processing
- Save material, save time, save processing cost
- 20 years of R & D experience, more reliable, more guaranteed

Split dies for spring clips, clamps, retaining parts and other special-shaped cold headed components — fastener forming tooling that matches unusual geometry while keeping production stable.
Parts that cannot be formed in a solid round die are formed in split (segmented) dies: the die halves open around the part contour, allowing near-net shaping of irregular profiles with clean part release.
We develop split die tooling together with your engineers — from prototype to patent-backed production processes. Our split die technology for long-length products is patented and has been an industry benchmark in China’s fastener industry since 2008.
For how the segments are designed, where the cavity is split and what it takes to make the parting line close without a step, read our guide to split die cold forming.
Split geometry is one answer, not the only one. For how we develop tooling for special-shaped parts that cannot be formed from the catalogue at all, see automotive non-standard fasteners.
Send the drawing — we’ll figure out the tooling.
The solid and segmented cavities themselves — grades, fits and station-by-station design — are covered under cold heading dies.
