Coffee Machine Torsion Spring

Solution

Features

1. High Torque Capacity: Engineered to deliver 5-8 Nm torque, this spring maintains optimal pressure for brewing mechanisms even after 50,000+ cycles, preventing mechanical slippage.

2. Precision-Tempered Material: Constructed from ASTM A228 music wire (carbon content 0.80-0.95%), providing tensile strength of 2,900-3,100 MPa for corrosion resistance and fatigue life exceeding 100,000 compressions.

3. Thermal Stability: Withstands operational temperatures from -30°C to +150°C due to silicon-alloyed steel composition, maintaining spring constant (k-value) within ±5% across this range.

4. Dimensional Accuracy: Features tight ±0.025mm wire diameter tolerance and ±1° coil angle precision, ensuring consistent force delivery across all coffee preparation phases.

5. Customizable Geometry: Available in 2-20mm wire diameters with customizable active coils (typically 3-12 turns), allowing torque adjustment from 3Nm to 15Nm for different machine models.

6. Vibration Damping: Incorporates 0.6-1.2 damping ratio to absorb operational vibrations, reducing acoustic noise by 12-15dB compared to standard springs.
