Value-Added Product Showcase



Title: Custom CNC Machined Mounting Blocks & Threaded Fasteners with Black Oxide Coating



Product Overview

At JST Mould (www.jstmold.com), our value-added manufacturing services include the mass production of custom CNC machined hardware for Tier-1 automotive assembly lines, robotic automation, and heavy-duty industrial fixtures. These customized threaded mounting blocks and T-slot components demonstrate our capability in rapid CNC milling, precision thread tapping, and durable surface treatments, providing a true Turnkey Solution alongside our elite injection molding services.


Value-Added Solutions: Precision CNC milling and durable surface treatments for heavy-duty industrial fixtures.


Key Engineering Features

  1. Precision CNC Milling & Turning: Manufactured from high-strength metal alloys, these custom structural blocks feature precision-milled stepped profiles and flat cutouts. Utilizing advanced DFM analysis and multi-axis CNC machining, we ensure perfect dimensional consistency across large-volume production runs, guaranteeing seamless integration into your automated assembly tracks.
  1. Micron-Level Thread Tapping: The integrity of a structural fastener relies entirely on its internal threads. Our rigid CNC tapping processes ensure that every deep internal thread meets strict international tolerance standards. This Micron-level precision prevents thread stripping under high-torque applications, ensuring long-term mechanical reliability for demanding US and German industrial standards.
  1. Black Oxide Surface Treatment (Anti-Corrosion): To extend the lifespan of these heavy-duty components, they undergo a premium Black Oxide (发黑) surface treatment. This specialized chemical conversion coating provides excellent mild corrosion resistance, minimizes light reflection, and prevents dimensional buildup—meaning the precision threads remain 100% accurate after treatment.
