Plain Guide Bushings (Demountable Style) Bronze-Plated Copper Alloy

These demountable guide bushings are used in injection mold die sets to maintain consistent alignment between moving and stationary plates, especially where frequent servicing is expected. The low-profile, inch-series format supports compact leader-ejector spacing in production tooling.

• Automotive connector and terminal molds: Use them in leader systems to stabilize die opening/closing and reduce misalignment during high-cycle runs. The bronze-plated copper alloy provides reliable sliding behavior under typical die-set contact pressures.
• Appliance and housing molds with frequent part changeovers: The demountable design allows faster guide component replacement during scheduled maintenance, minimizing downtime while preserving repeatable installation.
• General-purpose insert or ejector housings: When mounting flexibility is needed, the bushing package supports clip/screw assembly and can also be mounted using detachable mounting or Loctite-based installation.

Overall, the bronze-plated copper alloy variant suits applications where wear resistance at the guide interface and serviceability are both important.

The bushing body uses a bronze-plated copper alloy designed for smooth sliding at the die-set guide interface. The bronze plating improves surface wear behavior and helps maintain stable friction characteristics during repeated leader action.

• Wear vs. toughness trade-off: Bronze-plated copper alloys prioritize low-friction, anti-wear performance; compared with fully hardened tool steels, they are generally less suited for abrasive, extremely high-load guide conditions but provide excellent running behavior for standard die alignment.
• Heat treatment: The provided data specifies the alloy/plated configuration but does not list a defined heat-treatment state (e.g., quench & temper or nitriding). Selection should be based on the supplier’s supplied material condition for consistent bushing performance.

Manufacturing is typically achieved via precision casting or machining followed by plating to achieve the guiding surface characteristics required for repeatable sliding.

Select the correct bushing by matching both post diameter A and the required length L for your leader/bushing stack-up in the die set.

• Post diameter A (in): Available sizes are 1, 1 1/4, 1 1/2, 1 3/4, 2, and 2 1/2. Choose the A dimension that corresponds to your leader/post nominal diameter used in the die guide system.
• Length L (in): Available from 1.375 ~ 5.125. Ensure L provides sufficient bearing length for alignment across your open/close stroke and maintains stable guidance under load.

For assembly fit, verify the mating leader/post geometry and die-set bore specs against your drawing stack. Because the exact tolerance values are not provided here, confirm allowable clearance and interference using your mold design standards and the die-set interface dimensions (including any clip/screw or adhesive installation requirements).
