What is the difference between urethane casting and injection molding?

/ 15 minutes of reading / By /

The core difference between urethane casting and injection molding lies in material properties, production efficiency and precision level. Urethane casting uses room temperature curing resin, which is fast and low cost (especially for small batches), but is limited by strength (≤80 MPa) and precision (±0.3 mm), and is suitable for flexible, low-load short-term parts (such as cushions,

What Grounds Jets? Brake Discs & Retraction Actuators Under Fire

/ 11 minutes of reading / By / ,

The core causes of frequent groundings of jet aircraft are the thermal decay effect of brake discs and hydraulic hysteresis of retraction actuators: Emirates Boeing 777 failed due to delamination of carbon fiber brake discs at 1200℃ (NTSB report AAR-24/01), exposing the thermal resistance limit of traditional materials; Airbus A320neo fleet caused a 300% surge in the risk of landing
