product description
In connector PIN needles and medical device deep cavity molds, a 0.01 mm deviation in concentricity results in a 40% spike in thimble breakage. Our aerospace-class drum system uses Tungsten Carbide substrate and DLC coating at 30x diameter depth (L/D= 30) Hold under working condition ± 0.003mm dynamic concentric, is the 0.5mm miniature post position provides precise release force with zero deformation.

Product Features
1. Military-grade concentric system
- Two-material composite structure:
Inner cylinder: YG 15 Tungsten Carbide (compressive 3200MPa)
- Outer cylinder: H 13 Cobalt Alloy (Toughness Impact Value 45J/cm²)
- Coating: Diamond-like DLC (thickness 3μm)
- Dynamic guidance technology: spiral oil groove design, automatic compensation for thermal deformation deviation
- Anti-rotation pin patent: laser etched hexagonal anti-rotation surface + color locating ring
2.Deep Conquistador
- Limit depth-to-diameter ratio: L/D=30(Φ1mm×30mm to Φ 25mm×750mm full system coverage)
-  Micropore top air system (optional): Φ 0.1mm side wall pores, eliminate vacuum adsorption
- Burst-resistant design: R0.5mm stress dispersion fillet + longitudinal stiffener

Product application scenarios
1. Precision electronics: Type-C interface PIN pin demoulding (Φ 0.6mm)
2. Medical catheter: Minimally invasive surgical instruments are ejected from the deep cavity (L/D=25)
3. Automobile fuel injection nozzle: anti-sticking ejection of fuel injector column
4. Optical lens: non-destructive demoulding of cell tube of mobile phone camera
