Material & Tolerance
The standard material is listed below; also available in steel, stainless, brass and aluminium. Dimensions in mm; tolerances machined to ISO. Deviations (mm) are given for the nominal diameter according to the ISO 286-2 tables; thread tolerances (6g/6H) are to ISO 965. For custom sizes/tolerances, contact us with the part code.
Manufacturing Scope
Nitrided Ejector Pin is a Mold & Die Components family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀3–15 mm, lengths 33–123 mm, standard material Steel (also stainless steel, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request a quote with the code you need.
The family is machined from ⌀16 mm bar stock; its longest variant is KALA-NEP-09 at 123 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-NEP-02: 49 mm long at ⌀4 mm, a length-to-diameter ratio of 12.3. 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 h6 tolerance; the smallest is KALA-NEP-01 (⌀3 mm) and the largest KALA-NEP-09 (⌀15 mm). The family includes multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
