Production Process
01 Forging
Self-owned forging factory, using 31.5KJ CNC die forging hammer to forge blanks：
• Higher dimensional accuracy,
• Small machining allowance of products,
• Stable and reliable production capacity.
02 Machining
This machining stage integrates drilling, milling, shaping, and edge cutting to precisely process the workpiece. It transforms the rough blank into two functional metal components with accurate dimensions, curved handles, and sharp edges, ready for the final riveting assembly.
03 Heat Treatment
Heat treatment optimizes the hardness and toughness of plier blanks. Controlled quenching and tempering relieves internal stress, avoids deformation, and delivers excellent wear resistance and durable cutting performance.
04 High Frequency
Compared with traditional induction high frequency, laser processing has a more stable positioning tool, so that the hardness of the cutting edge is more uniform，this process allows us to achieve the high degree of reliability, durability and service life that are the very definition of SANTU pliers.
05 Automatic Polishing
Compared with traditional manual polishing, the pliers after automatic polishing have better dimensional accuracy and better dimensional consistency .
06 Visual Capture Marking
Compared with the traditional marking machine with tooling, the positioning of the visual capture marking machine is more accurate, which reduces the positioning error that is easily caused by human operation.
07 Swing Ultrasonic Cleaner
Through high-frequency passive opening and closing, the oil stain inside the shaft of each pliers is removed as much as possible, so as to avoid continuous oil stain leakage during subsequent use.
08 Automatic Handle
This automatic handle sleeving stage integrates feeding, positioning and sleeve assembly to fit protective insulation sleeves onto plier handles. It ensures uniform bonding quality and accurate positioning, improves production efficiency and minimizes manual errors, producing comfortable, non-slip and insulated grips for finished pliers.
