In automotive injection molding, sprue materials from large components (e.g., fuel tanks, seat frames) can account for up to 30% of production. Our large central crushers feature a double-layer soundproof design and high-torque cutting blades, achieving hourly processing capacities of up to 800kg. They produce uniform, dust-free granules when crushing engineering plastics like PE, PP, and ABS, allowing direct recycling with up to 25% incorporation ratio. Fully automated dust removal and shock absorption systems integrate with central feeding setups, helping automotive parts manufacturers achieve green production and save millions annually in material costs.
