In precision injection molding, die casting, and extrusion, hot runner systems act as the “vascular network” of production, where performance dictates product quality and efficiency. When molten material at 300–450°C flows under extreme pressure, only aerospace-grade stainless steel and nano-scale precision can meet such demands. We deliver zero-leak sealing, pinpoint thermal control, and extended longevity to conquer the harshest operating conditions.
I. Critical Performance Thresholds
Challenge | Our Solution | |
---|---|---|
High-Temp Sealing | Thermal expansion leaks | Metal seals + thermal-compensation design |
Pressure Fatigue | Cyclic stress-induced cracks | FEA-optimized wall thickness/ribs |
Flow Path Smoothness | Residue carbonization & clogging | Mirror polish (Ra ≤0.1μm) + EP passivation |
Thermal Uniformity | Local hot/cold spots causing drool/short shots | Gradient heat pipes + AI temperature control |
Weld Integrity | Stress corrosion cracking (CLSCC) | Pulsed TIG + solution treatment |
