Brass Insert Nut, Precision Embedded Brass Inserts for Plastic Injection Molding
Product Overview
This brass insert nut is a precision embedded fastener specially designed for plastic injection molding. Manufactured by CNC turning, the outer surface is made with anti-twist knurling. When precast into plastic housings, it forms a firm combination with the plastic base. It is widely used in 3C electronics, AI smart equipment, sensor shells, household appliances and plastic structural parts. With stable thread precision and excellent thermal conductivity, it effectively prevents nut rotation, pull-out and loosening during long-term equipment operation.Core Processing Advantages
Threads pass 100% go and no-go gauge inspection
All internal threads are precisely machined with standard tooth profile and uniform pitch. The go gauge can be fully screwed in smoothly without jamming, while the no-go gauge meets the tolerance requirement. No bad threads or burrs remain. Screws fit tightly during assembly without slipping, which greatly reduces the rework rate of electronic finished products and adapts to automated assembly production lines.Stable dimensional tolerance with high consistency
One-time clamping CNC machining strictly controls the outer diameter, length and concentricity. The size deviation of the same batch is kept within a small range. The embedding depth stays consistent during injection molding, so there will be no uneven protrusion or depression on the plastic surface. Mass interchangeability is guaranteed without manual sorting.Burr-free finish to protect plastic and electronic components
After precision deburring, all thread openings, end faces and knurl edges have no sharp flash. It will not cut plastic materials during molding, nor scratch PCB boards, wires and sealing parts during assembly, avoiding damage to precision electronic elements.Good material performance of solid brass
Solid brass material features high hardness, anti-torsion property and outstanding thermal conductivity. It can effectively conduct heat generated by chips and circuit boards inside the equipment. Meanwhile, brass resists oxidation and corrosion in closed humid environments, keeping stable connection performance for a long time.Main Application Scenarios
AI intelligent equipment plastic shell
Suitable for inspection robots, visual testing modules and edge control cabinet housings. Knurling locks tightly with plastic to avoid nut spinning under continuous vibration, ensuring accurate positioning of sensors.3C consumer electronics injection molding
Applied to smart cameras, portable terminals and small electrical casings. Compact size saves internal space, and brass material prevents rust and improves heat dissipation.Plastic brackets and testing jigs
Embedded fixing for plastic structural parts of automation tooling. High pullout resistance keeps the connection tight under repeated movement.Solutions to Common Problems
Problem 1: Nuts rotate or pull out after being embedded in plastic
Solution: The outer knurling increases biting force with plastic. Torsion and pullout resistance are significantly improved to avoid displacement caused by vibration.Problem 2: Poor thread accuracy leads to sliding teeth during assembly
Solution: CNC precision thread turning plus full gauge testing ensures standard meshing and stable locking force.Problem 3: Sharp burrs pierce plastic shells and scratch circuit components
Solution: Full deburring treatment makes all surfaces smooth, protecting plastic appearance and precision electronic parts.Custom Service
