Component responsible for injecting molten metal into the die cavity under high pressure

Product Specifications

Technical details and manufacturing context for Injection System

Definition
The injection system is a critical component of a High-Pressure Die Casting Machine that precisely meters and forces molten metal into the die cavity under controlled high pressure and velocity to form complex metal parts with minimal porosity and excellent surface finish.
Working Principle
The system receives molten metal from the holding furnace, uses a shot sleeve and plunger to accumulate and measure the required volume, then rapidly injects the metal into the die cavity through the nozzle and runner system under hydraulic or servo-electric actuation, with precise control over injection speed, pressure, and timing.
Common Materials
Tool steel, Heat-resistant steel, Ceramic components
Technical Parameters
  • Plunger diameter and stroke length determining shot volume capacity (mm) Standard Spec
Components / BOM
  • Shot Sleeve
    Receives and holds molten metal before injection, provides thermal insulation
    Material: Heat-resistant steel
  • Plunger
    Forces molten metal through the shot sleeve into the die cavity
    Material: Tool steel with wear-resistant coating
  • Nozzle
    Connects injection system to die, directs molten metal flow
    Material: Heat-resistant steel or ceramic
  • Injection Cylinder
    Hydraulic or servo-electric actuator that drives the plunger
    Material: Steel with precision machining
Engineering Reasoning
80-120 MPa injection pressure, 650-720°C molten aluminum temperature, 0.5-2.0 m/s injection velocity
Plunger seal failure at 150 MPa injection pressure, nozzle solidification at 580°C molten metal temperature, die erosion at 3.5 m/s injection velocity
Design Rationale: Plunger seal failure due to exceeding yield strength of H13 tool steel (1650 MPa ultimate tensile strength), nozzle solidification from heat transfer exceeding latent heat of fusion (397 kJ/kg for aluminum), die erosion from kinetic energy exceeding 12.25 J/kg at 3.5 m/s velocity
Risk Mitigation (FMEA)
Trigger Hydraulic pressure spike exceeding 150 MPa due to servo valve malfunction
Mode: Plunger rod buckling failure with 15 mm permanent deformation
Strategy: Pressure relief valve with 140 MPa cracking pressure and 10 ms response time
Trigger Thermocouple calibration drift causing 50°C temperature measurement error
Mode: Aluminum solidification in nozzle creating 5 mm blockage
Strategy: Redundant RTD sensors with 0.5°C accuracy and automatic calibration every 100 cycles

Cause: Wear from cyclic pressure, thermal degradation, chemical attack, or improper installation causing fluid loss and potential environmental/safety hazards.
Maintenance Indicators
  • Irregular spray pattern or pulsating flow during operation
  • Audible hissing or dripping sounds at connection points indicating leaks
Engineering Tips
  • Implement strict fluid filtration and regular fluid quality testing to prevent contamination-related failures
  • Establish predictive maintenance using vibration analysis and thermal imaging to detect early wear in moving components before catastrophic failure
