Brass Moulding Insert (Straight Knurl)
A compact brass moulding insert featuring straight knurling pattern, optimized for press-fit and ultrasonic installation in thin-walled plastic parts. The straight knurl provides a simple yet effective grip, reducing stress concentrations and minimizing the risk of cracking in delicate host materials. Available in outer diameters from 3mm to 20mm. Commonly used in electronics housings, terminal enclosures, LED lighting fixtures, and consumer electronics where dimensional accuracy and material integrity are critical.
Key Highlights
