FAQ

Q: Why is corrosion resistance critical for rubber processing screws?
A: Rubber compounding often involves:
- Halogenated flame retardants
- Sulfur-based vulcanization agents
- Acidic process aids
These chemicals aggressively attack standard steel, causing pitting and premature failure. Corrosion-resistant materials prevent contamination and extend service life.

Q: Can you match my existing screw profile?
A: We provide:

· Reverse engineering of worn elements

· CAD matching to OEM specifications
· Performance upgrades to existing designs

Q: What material options are available for corrosive rubber applications?
