| 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. |
