Stock Pusher for Spring (Inch)

This inch-size stock pusher is used inside injection mold tooling and spring-handling stations where controlled placement of coil springs is critical before final assembly. It can be integrated into a mold-side or assembly jig that feeds springs to downstream components, helping maintain consistent orientation and preventing displacement during transfer.

• Automotive and industrial subassemblies: In connector, latch, or actuator assemblies, the pusher’s rigid steel construction helps keep coil springs seated in a repeatable position during stacking and installation onto pins or housings.
• Appliance and pump part assembly: For spring-loaded mechanisms, it supports organized in-process staging so operators can handle multiple spring lots with fewer interruptions, reducing downtime caused by misplacement.
• Medical and precision device housings: In fixtures used to position small springs, stable guide length (L) supports repeatability when springs must be reliably presented to fine mating parts.

Choose the inch variant when your tooling design uses inch-based guide dimensions and you need dependable spring organization with a compact guide length.

The provided metadata specifies a steel stock pusher. In mold-adjacent assembly fixtures, steel offers strong dimensional stability under handling forces and good resistance to wear from repeated contact during spring positioning.

• Heat treatment: No exact grade, hardness, or heat-treatment state (e.g., quenched & tempered, nitrided) is listed in the input data, so selection should be verified against the manufacturer’s datasheet for the exact DANLY IEM material specification.
• Properties trade-off: Typically, hardened tool steels increase wear resistance but can reduce toughness if over-hardened; annealed or pre-hardened conditions improve toughness but may wear faster. Confirm the target duty cycle for your spring volume and contact surfaces.
• Manufacturing process: As a guide component, it is commonly produced with controlled straightness and surface finishing to support consistent spring seating; inspect guide surfaces for burr-free edges to avoid spring snagging.

Selection for this inch stock pusher is driven by the guide length (L) requirement. Your design should match the available guide lengths of 2-13/16 in and 3-3/8 in to ensure the pusher properly supports the spring during feed and seating.

• Match to cavity/jig geometry: Measure the required support distance from the point where the spring is presented to the point where it must be fully positioned. Select the L value that provides full coverage without excessive overhang into nearby features.
• Tolerance and fit: While no numeric tolerances are provided, assume the guide must be sized to prevent spring drift while still allowing smooth insertion. Validate clearances in CAD against spring outer diameter and coil geometry, and confirm that the guide surfaces are free from burrs.
• Configurable vs. fixed dimensions: In the available options, L is a fixed selection per product variant (2-13/16 in or 3-3/8 in), not a field-adjustable parameter.

Once L is selected, lock the fixture location so repeatable spring positioning is maintained across production cycles.
