Straight Ejector Pin

Manufacturing Scope

Straight Ejector Pin is a Mold & Die Components family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀4–18 mm, lengths 44–140 mm, standard material Steel (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.

The family is machined from ⌀18 mm bar stock; its longest variant is KALA-EJP-10 at 140 mm. The family is produced by turning alone. All of it is completed in a single setup, without the part leaving the machine.

The most slender variant is KALA-EJP-01: 44 mm long at ⌀4 mm, a length-to-diameter ratio of 11.0. This ratio is the very reason sliding-head lathes exist. The guide bushing supports the bar immediately beside the cutting point, so there is no deflection; the same part chatters and drifts in diameter on a conventional lathe.

Variants are machined to g6 tolerance; the smallest is KALA-EJP-01 (⌀4 mm) and the largest KALA-EJP-10 (⌀18 mm). The family includes multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
