Heat set brass inserts
DBI-055
Heat Set Brass Inserts are precision threaded components made from brass and designed to be embedded into plastic parts to create strong, durable, and reusable metal threads. These inserts are widely used in 3D printing, injection molding, and plastic fabrication applications where reliable threaded fastening is required.
By installing a metal insert into plastic components, heat set inserts significantly improve the strength, wear resistance, and longevity of threaded connections compared to threads cut directly into plastic.
TO What They Are
- Material:Â Brass (chosen for its good thermal conductivity and corrosion resistance)
- Shape:Â Usually knurled or with a helical knurling to ensure a strong bond with plastic
- Sizes:Â Vary by thread size (e.g., M2, M3, M4, etc.) and length
Benefits
- Reusable threaded connection
- Much stronger than threading directly into plastic
- Clean, professional look
- Great for parts that will be assembled/disassembled frequently
Applications
- Air Conditioning Systems
Hydraulic Systems
Marine Equipment
Mechanical Systems
Refrigeration Systems
Tips for Successful Installation
- Hole Preparation:Â Ensure the hole diameter matches the insert specifications (e.g., 3.2mm for M3 inserts).
- Temperature Settings: Use a soldering iron set between 180°C and 220°C, depending on the plastic material.
- Pressing Technique:Â Insert the heated brass insert vertically into the hole using a press tool or tweezers until it is flush with the surface.
- Cooling:Â Allow the plastic to cool and solidify around the insert for a secure bond.
