Custom Die-Forged Scraper Chains – Precision Stainless & Carbon Steel Forgings
Product Overview : Custom Die-Forged Scraper Chains
Material : High-grade Stainless Steel & Carbon Steel
Process : Precision Die Forging (Closed-Die/Hot Forging)
Applications : Conveyor systems, agricultural machinery, industrial scrapers, mining equipment, and heavy-duty material handling.
Key Features :
✅ Superior Strength – Forged microstructure enhances durability and load-bearing capacity.
✅ Wear & Corrosion Resistance – Stainless steel options for harsh environments (food, chemical, marine).
✅ Tight Tolerances – Precision forging ensures consistent dimensions (±0.1–0.3mm).
✅ Custom Designs – Tailored links, pitches, and attachments to fit OEM specifications.
✅ Cost-Effective – Reduced machining needs vs. traditional fabrication.
