Mold-in Inserts

Rotaloc Cluster

Rotaloc designs and manufactures a full range of standard and custom mold-in inserts. We are experts in rotational molding and understand the unique challenges that must be considered for the successful design and molding of inserts into molded parts.  We utilize our extensive experience in this area and work closely with our customer to help identify the best product for each application. Before selecting an insert for a given application, we often discuss the forces that the insert will be subjected to (Torque, Tensile, Vibration, Static or Dynamic…) and take into account wall thickness, insert location and resin properties.  Ultimately, we supply a burr-free part that is cleaned and free of contaminants such as oils and cutting fluids. Where applicable, parts may undergo specialized cleaning processes such jet washers, or oxidized and individually poly-bagged.
Our full range of stock and custom inserts include:
  • Hex Inserts
  • Square Inserts
  • Geoserts
  • Inserts for Sending Units
  • Round Knurled Inserts
  • Specialty Inserts
  • NPT, SAE and BSP Inserts
  • T-Nuts and Nutserts
  • Roto-Style Inserts
  • Up to 100% Inspection Rates on Parts
