What Are Pins?

Die casting pins are precision-machined, heat-treated steel components that form holes, slots, and internal features within the die cavity. Core pins form blind or through holes. Jet cool (JC) pins incorporate an internal bore through which high-pressure water or air is directed to remove heat from hot-spot zones that cannot be cooled by conventional water circuits. Profile pins extend this capability to non-circular cross-sections.

Core pins and jet cool pins are the most frequently replaced consumable components in any die casting operation. Their performance directly impacts hole quality, cavity surface integrity, and overall cycle efficiency. Vyankatesh Engineering manufactures the full range of die casting pins — from standard core pins and long jet cool pins to complex profile pins — from certified DIN 1.2344 / AISI H-13 tool steel, processed through our complete managed heat treatment and surface finishing sequence.

Benefits

Extended Service Life

Vacuum hardening + nitriding delivers hardness of 44–48 HRC with a wear-resistant nitrided surface layer, significantly outperforming un-treated alternatives.

Reduced Cycle Times

Jet cool pins remove heat directly from the pin tip, enabling faster solidification and shorter cooling dwell — directly reducing cycle time and improving productivity.

Dimensional Consistency

Precision-ground to h6–h8 tolerances with straightness verified to ≤ 0.01mm / 100mm, ensuring consistent hole geometry batch after batch.

Custom to Drawing

Any diameter, length, profile, or cooling channel arrangement manufactured from customer drawings, CAD files, or physical samples.

Fast Turnaround

Dedicated in-house CNC turning, grinding, and inspection facilities, coupled with certified heat treatment partners, enable competitive lead times without quality compromise.

Full Dimensional Accuracy

All pins are manufactured with strict precision, ensuring exact shape, size, and long-lasting quality for critical applications.

Manufacturing Process

Every pin at Vyankatesh Engineering goes through a controlled, documented manufacturing sequence from certified raw material to finished, inspected component.

1
Raw Material

Premium DIN 1.2344 / AISI H-13 billet sourced for optimum density, ensuring precision shape and long-lasting quality.

2
CNC Turning

Rough and semi-finish turning to leave grinding allowance. Deep-hole drilling for jet cool bores

3
Vacuum Hardening

Vacuum heat treatment with controlled gas quench for uniform 44–48 HRC hardness

4
Precision Grinding

OD grinding and bore grinding to final h6–h8 tolerances and Ra ≤ 0.4μm surface finish

5
Nitriding

Gas nitriding creates a hard compound layer (900–1200 HV) without dimensional change

6
Inspection

100% measurement of diameter, length, straightness, bore concentricity, and hardness
