At Viiplus, we deliver defect-free, high-performance copper castings using advanced centrifugal casting, continuous casting, and CNC precision machining.
From 2-ton copper bushings to 4-meter slide plates, custom bronze worm gears, and high-density copper billets, our solutions serve global leaders in metallurgy, marine, mining, construction, and mold manufacturing industries.

1. Advanced Casting Technologies & Material Systems

Manufacturing Process Overview

2. Copper Alloy Material Matrix & Performance

3. Future-Ready Material Innovations

• Graphite-Embedded Self-Lubricating Plates – Friction coefficient as low as 0.08

• Copper-Aluminum Hybrid Castings – Up to 30% weight reduction without compromising strength

• Multi-Zone Alloy Casting – Hard outer shell + ductile core in a single pour

4. Real-World Applications, Pain Points & Proven Solutions

Large-Scale Copper Bushings

Applications:
Port crane boom bearings · Continuous casting roller sleeves · Hydraulic cylinder bushings · Die-casting machine columns

Pain Points:

• Extreme loads (>20 MPa) and constant wear

• Thermal expansion causing ovality and seizure

• Downtime losses exceeding $50,000/hour

• Long lead times (8–12 weeks) from unreliable suppliers

Our Solutions:

• Centrifugal casting + vacuum degassing → 100% dense microstructure

• Materials: CuSn12 / CuAl10Fe5Ni5

• Design: Pre-machined oil grooves & graphite plugs → 3× service life

• Rapid prototyping: 3D-printed molds → prototypes in ≤10 days

• On-site alignment support using laser measurement tools

Large Copper Slide Plates & Guide Rails

Applications:
Continuous caster mold tables · Forging press guide rails · Mold ejection systems · Port machinery guide plates

Pain Points:

• High friction and galling

• Lubricant breakdown at 200 °C+

• Warping and flatness loss (<0.2 mm/m) after machining

Our Solutions:

• Graphite-Plugged Bronze (CuZn25Al5Mn4Fe3) → Friction coefficient 0.08–0.12

• Stress-relief annealing + 5-axis CNC → Flatness ≤0.1 mm/m

• Custom CAD-to-CAM workflow → Any profile, any size, delivered in 3–4 weeks

Complex & Multi-Material Copper Parts

Applications:
Die-casting mold inserts · Automation sliding assemblies · Hybrid copper-steel guide blocks

Pain Points:

• Complex shapes → high rejection in traditional casting

• Inconsistent hardness across wear zones

• Long validation cycles (6–8 weeks)

Our Solutions:

• Multi-Alloy Zone Casting: Hard face (CuAl10) + soft core (CuSn10) in one pour

• AI-Powered Material Selector: Input load, speed, temperature → instant alloy recommendation

• Digital Twin Simulation: Predict wear before production

• Low MOQ (1–50 pcs) with full material certification & UT reports

5. Copper Alloy Billets – The Foundation of Precision Manufacturing

Value Proposition:
✅ Up to 60% less machining time
✅ Lower scrap rates with pre-qualified alloy chemistry
✅ Full traceability: batch number, melt analysis, and UT logs
