Heat set brass inserts
DBI-055
Heat Set Brass Inserts are precisely threaded brass bits that are intended to be immersed into plastic components to provide robust, long-lasting, and reusable metal threads. When dependable threaded fastening is needed, these inserts are frequently utilized in 3D printing, injection molding, and plastic fabrication applications.
When compared to threads that are cut directly into plastic, heat set inserts greatly increase the strength, durability, and wear resistance of threaded connections by inserting a metal insert into plastic components.
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.
