1. Core Mold & Punch
- Directly contact metal materials under continuous high‑pressure pressing.
- Subject to strong friction and extrusion, causing dimensional and surface wear.
- Regularly check accuracy and flatness to ensure high density and molding quality.
2. Hydraulic Seal Components
- Sealing rings and dust rings prevent oil leakage in the hydraulic system.
- Prone to aging, deformation, or damage from high‑frequency hydraulic shock.
- Immediate replacement required if seals fail to maintain system pressure.
3. Mechanical Transmission & Guide Parts
- Guide rails, slide blocks, and bearings provide guidance and support.
- Metal dust penetrates gaps, accelerating wear.
- Fasteners are prone to loosening or fatigue failure under long‑term vibration.
4. Filtering & Cooling Components
- Filter element gradually clogs with oil impurities and iron filings.
- Cooler may suffer pipeline aging or blockage from thermal cycling.
- Regular replacement and cleaning extend hydraulic system life.
