Output values are catalogue maxima without a specified compound test condition. They are not guaranteed for every material. Compound, screw design, head tooling and thermal process must be confirmed together.

Questions About This Machine
Can one screw process every listed compound without adjustment?
The list describes application scope, not universal screw compatibility. Confirm the screw, barrel, head and thermal process for the actual compound.
Is 1300 kg/h available on every model?
No. It is the catalogue maximum for SJ200×25. Smaller screw sizes have different values, and actual output depends on the compound and operating conditions.
