Custom OEM Fine Blanked Folding Knife Liners and Frame Locks | Boomster
Boomster utilizes advanced fine blanking technology to manufacture high-strength stainless steel knife liners, liner locks, and frame lock plates for premium tactical and outdoor folding knives. Produced strictly per client-provided 2D/3D CAD models, Boomster’s custom fine-blanked liners achieve 100% smooth shear edges, precise pivot pin hole alignment, and clean weight-reduction skeletonizing. Operating under an ISO 9001:2015 certified quality system, we deliver heat-treated, burr-free knife liners engineered for flawless lock engagement and zero blade play. Why Choose Boomster? Precision Piercing for Detent Ball Holes & Jimping Patterns: We integrate micro-hole punching for detent balls, thumb jimping serrations, and pocket clip mounting threads directly into multi-station fine blanking dies, maintaining exact pitch-to-pitch consistency. High-Strength Stainless Steel & Titanium Alloy Options: We process premium blade-hardware alloys—including SUS420J2, SUS301, SUS304, 440C, and TC4 Titanium—offering high yield strength, excellent spring memory for locking arms, and superior corrosion resistance. Controlled Heat Treatment & Spring Tension Tuning: Boomster provides specialized vacuum heat treatment, stress relieving, and tempering services to optimize the hardness (HRC) and fatigue strength of liner locks, preventing lock failure under extreme field use. ISO 9001:2015 Quality System & Flatness Verification: Every production run undergoes strict CMM dimensional checks, optical profile inspection, and flatness checks. We deliver raw material mill test certificates and RoHS/REACH compliance documentation with every shipment. Guaranteed 3-Year Quality Inspection Report Retention: Boomster securely archives all Inspection Reports (IR), fine blanking die maintenance logs, and heat treatment batch certificates for at least 3 years from the shipping date, supporting seamless global regulatory audits. Custom Surface Finishes & Global Container Consolidation: From bead blasting, stonewashing, and black oxide to PVD coatings, Boomster offers comprehensive OEM finishing, short lead times, and container consolidation across custom metal and plastic hardware lines. High-tolerance CNC machined parts with ±0.005mm precision. Boomster offers turning, milling, drilling, and prototyping-to-mass production for all industries.
