Blind Threaded Brass Inserts with Closed End Design
Lead-free custom precision fasteners designed for clean injection molding applications
Blind Threaded Brass Inserts Overview
In insert molding processes, molten plastic easily seeps into the threads of through-hole nuts, requiring additional tapping cleanup operations that add cost and time. Our brass inserts with blind closed-end design structurally block plastic melt from entering the threaded area, eliminating post-processing steps while ensuring thread cleanliness and integrity for reliable screw fastening.
Precision Manufacturing Process
Using Swiss-type lathes, we complete turning, drilling, tapping, and end-face closure in a single setup, ensuring uniform bottom wall thickness with no leakage risk. The closed-end design acts as a physical barrier during insert molding, completely blocking molten plastic from entering the threaded area. After ejection, you receive finished components with clean threads requiring no secondary operations.
This design is particularly valuable for micro inserts (M2-M3) where thread cleaning is difficult and prone to damage. As a certified factory with 15 years of precision manufacturing experience serving 2,000+ global clients, we are committed to eliminating hidden costs and quality risks from your production at the design stage.
Product Features & Advantages
| Feature | Advantage to You |
|---|---|
| Completely Eliminates Flash Issues | Closed-end design creates a physical barrier that completely blocks plastic melt from entering the threaded area during insert molding. Eliminates post-cleaning steps, reducing manufacturing cost and improving production efficiency. |
| Protects Thread Precision & Cleanliness | No secondary tapping required; threads remain in factory-precise condition. Ensures consistent screw fastening torque, avoiding stripping or insufficient clamping force due to incomplete cleaning. |
| Ideal Choice for Micro Inserts | For micro threads like M2 and M2.5, cleaning easily damages thread profiles. Blind hole design fundamentally solves this issue, making it the preferred solution for precision micro assemblies. |
| Customizable Blind Depth & Wall Thickness | We can customize blind hole depth and bottom wall thickness based on your mold design and strength requirements. Ensures anti-flash functionality without compromising overall insert strength. |
| 15 Years Precision Turning Expertise | Swiss-type lathes complete machining in one setup, ensuring uniform bottom wall thickness. IATF16949 certified quality with high batch-to-batch consistency. |
