Compression Limiters

Compression limiters are non-threaded inserts designed to protect plastic parts from loads created by the tightening of bolts. The load causes compression, which can lead to cracking and creep due to tightening torque. Vogelsang offers an extensive line of cost saving compression limiters. Multiple design options in our compression limiters combined with our dedicated team allows your product to incorporate different shapes, materials, features and overall cost saving!

compression limiters Applications

  • Polymer based parts requiring a positive stop to prevent bolts from cracking the poly product.
  • Valve covers
  • Transmission & Oil pans
  • Water pumps
  • Engine covers
Possible Designs

  • Straight seam
  • Flanged end
  • Outer surface knurl
  • Multiple surface treatments
  • Heat treating available
Problem Example: Customer has a need for a tubular compression limiterProblem: Cut tubing is not cost effectiveExample Solution: Low cost slit seam design meets all customer requirements

The benefits to you:

  • Design compliant product with exceptional quality.
  • Cost advantage

Common applications include plastic molding, rubber molding, fiberglass molding and composite materials. The use of plastics to replace metal in engineered components demand is growing. Our engineering team can assist your efforts to produce a world class product.

Your advantage from a single source

Compression limiters protect plastics against excessive clamping forces, and can be:

  • molded in place or inserted after injection molding
  • installed with little effort since their design facilitates problem-free, automatic or manual insertion
  • rolled to exacting tolerances

The logical, cost-effective solution over inserts, tubular products or formed parts

Characteristics of insertion parts:

  • open slot
  • self-retaining through custom radial pre-tension design
  • free state diameter is slightly larger than the cavity into which it is to be fitted
  • accommodates broader thermal/range than solid spacers
  • can be produced for elongated holes and special contours

Characteristics of injection parts:

  • closed butt joined seam
  • knurled or smooth finish
  • tight length and OD/ID tolerance
