Brass Inserts Manufacturer in Jamnagar: Precision Threaded Solutions for Plastic Molding & Industrial Assembly
Why Brass Inserts Are Critical for Strong Plastic Assemblies
Plastic threads strip 40% of the time. Furniture, electrical enclosures, automotive panels – all fail when molded threads pull out under load. Brass inserts create metal threads in plastic with 10x pull-out strength – permanent fix for high-stress assemblies.
Jamnagar produces 70% of India’s brass inserts. But inconsistent knurling causes 15% molding rejects. Boltorq Brassmet’s inserts use hexagonal knurling + C36000 free-cutting brass for zero pull-out in PA6, ABS, and polycarbonate applications.
“Boltorq inserts dropped our furniture assembly failures from 12% to 0.3%. Threads hold forever.”
– S. Verma, Godrej Interio Manufacturing
