VCN229-G-Black Plastic Knob Carbon Steel Indexing Spring Plunger Mold Auxiliary Components

Carbon Steel Threadless Indexing Plunger Introduction

●Product Introduction

  This threadless indexing plunger is precision turned from high-quality carbon steel, featuring an integrated segmented structure consisting of a knurled anti-slip base, a thickened central cylindrical body and a top locating pin. The whole part adopts black oxide finish for rust resistance and abrasion resistance, presenting a solid matte black appearance.. 

●Structural Features

• High-Precision Elastic Indexing & Positioning

  The bottom cylindrical locating pin springs out automatically via internal spring to fit workpiece locating holes tightly, realizing station indexing and fixed limit, ensuring consistent dimensional accuracy for mass production.

• Threaded Lock Mounting for Confined Spaces

  Top external thread with lock nut enables fast secure installation, no extra space reserved for knob operation, ideal for built-in assembly inside narrow cavities and compact equipment.

• Ultra-Compact Knobless Design

  Eliminates external operating handle and knurled base to greatly reduce radial footprint, avoiding collision and scratch interference between knob and workpieces or fixtures.

• Long Service Life with Carbon Steel Black Oxide Finish

  High-strength carbon steel construction paired with full black oxide treatment blocks corrosion from water and cutting fluid, resisting rust and abrasion under frequent retraction cycles for long-term service.

• Built-in Elastic Self-Locking Against Position Shift

  Internal spring supplies steady ejection tension; the pin stays locked extended without external pressing force, preventing accidental retraction and position deviation during processing.

• Manual / Automatic Press Retraction

  The pin can be retracted by fixture stoppers for automatic station switching on production lines, or manually pressed to unlock indexing position.

●Typical Applications

• ● Tooling, Jigs & Fixtures:

• Station switching positioning for stamping fixtures, welding positioning jigs and inspection gauges, indexing limiting for multi-process machining

• ● Automated Equipment Frames:

• Gear positioning for production line carriers, transfer platforms and rotary workbenches to fast-switch machining stations for different workpieces

• ● Mechanical Equipment Adjustment Mechanisms:

• Angle indexing fixing for machine auxiliary baffles, conveyor limit brackets and instrument racks

• ● Mold Auxiliary Components:

• Side positioning for simple injection molds and small stamping dies, quick mold change indexing positioning

• ● Light Assembly Equipment:

• Manual simple positioning mechanisms for electronic component assembly jigs and hardware fitting workstations

• ● Warehousing & Logistics Tooling:

• Layer limiting for material turnover jigs and storage racks, gear fixing for sorting fixtures
