Featuring an outer Ni‑Cr self‑fluxing alloy coating by laser cladding, it achieves metallurgical bonding rather than the mechanical adhesion of HVOF thermal spraying, delivering 5 times higher bonding strength.  HVOF thermal‑spray coatings exhibit mechanical adhesion with a bonding strength of 50-80MPa and suffer from inherent porosity. Under cyclic thermal shock during die‑casting operations, the coatings are prone to delamination and spalling, with resultant debris contaminating the cast components. Our process achieves metallurgical bonding with strength of 300MPa, delivering superior durability along with low residual stress, ultra-low dilution, and crack‑free coatings.  With good high‑temperature resistance, wear and corrosion resistance, as well as good resistance to molten-aluminum adhesion, it improves die casting quality while maintaining high p...

Conventional ring-fitted plunger tips exhibit gaps inherent to their mechanical assembly. These gaps permit the infiltration of molten aluminum, leading to adhesion and corrosion that foster hard-particle formation, severe adhesion renders the removal of these rings labor-intensive and inefficient.    The wear mechanism of the assembled structure involves the superposition and mutual promotion of multiple wear forms, it’s not a simple "1+1" effect, but a further amplification of the deterioration process. More importantly, the failure mode of such assembled plunger tips is highly concealed, and its service life attenuation curve shows virtually no obvious warning phase.   The composite plunger tip features multifunctional coating that combines the high thermal conductivity of copper alloy, it achieves metallurgical bonding without any assembly gaps, delivering e...

The premium plunger tip delivers outstanding performance under harsh working conditions including large-tonnage machines, fast production cycles and high injection pressures.  HVOF thermal‑spray coatings exhibit mechanical adhesion and suffer from inherent porosity. Under cyclic thermal shock during die‑casting operations, the coatings are prone to delamination and spalling, with resultant debris contaminating the cast components. Our process achieves metallurgical bonding with strength of 300MPa, delivering superior durability along with low residual stress, ultra-low dilution, and crack‑free coatings.  Featuring excellent high‑temperature resistance, wear and corrosion resistance as well as outstanding resistance to molten-aluminum adhesion. The coating delivers outstanding friction-reduction, self-lubricating and anti-seizure properties under the high-temperat...
