New precision machined compression limiters protect plastic assemblies

SPIROL has just introduced its new Series CL6000 lightweight, lead-free, Aluminum Precision Machined Compression Limiters. Compression Limiters are designed to reinforce high-stress joints in plastic assemblies where bolts are used to connect two components to each other. They protect the plastic from excessive compression by absorbing the load when the bolt is tightened to the recommended tightening torque. This ensures the durability and reliability of the joint throughout the product's lifespan.

The CL6000 is machined from 2024 aluminum, which provides the best combination of strength, corrosion resistance, machineability, and cost. The CL6000 aluminum Compression Limiters are 40% stronger and one-third the weight of the same Compression Limiter manufactured from brass.

For applications that require extra bearing surface for the mating component, the CL6100 Headed Compression Limiter has all of the same features of the CL6000, with the addition of a head. In addition, for applications that require a galvanic alternative to aluminum, SPIROL has simultaneously launched the new CL8000 brass precision machined Compression Limiters, as well as the CL8100 headed brass version.

SPIROL offers several different standard types of Compression Limiters to meet specific application requirements and assembly methods. The current Series CL600 and CL800 lines of machined Compression Limiters are being replaced with the enhanced CL6000 and CL8000 based on the following benefits:

  • Precision: Enhanced control of critical features and better geometric dimensioning and tolerancing make this series ideal for highly automated or molded-in assembly processes.
  • Retention: Superior knurl formation and control result in more consistent and robust retention performance in post-mold assembly processes.
  • Product range: A larger selection of standard products meets expansive application requirements and preferences.

The new standard Precision Machined Compression Limiters are available in a wide range of standard sizes, in both aluminum and brass, and in headed and non-headed configurations:

According to engineers at SPIROL, the function and total overall cost of the assembly vary drastically based on the type of Compression Limiter used in the application. SPIROL's Engineering team will help determine the most appropriate Compression Limiter based on the specific application and assembly requirements.
