Die-casting finishing involves machining (e.g., drilling, tapping, milling) and surface treatment (e.g., plating, passivation, anodizing, electrophoresis, powder coating, painting). The selection of cutting fluid significantly impacts the machining quality of aluminum die-cast parts, and improper usage is one of the leading causes of workpiece rejection.
Cutting Fluid for Die-Casting Finishing

Q&A: What are the main challenges in selecting or using cutting fluids?

    Difficulty in finding a universal cutting fluid suitable for various aluminum die-casting processes.

    Corrosion and mold growth frequently occur when machining ADC12 and similar die-cast parts.

    Tool breakage and tap failures often happen with high-precision aluminum die-cast parts requiring superior surface finishes.

    Short lifespan and rapid odor formation in cutting fluids, negatively affecting the work environment.

    High oil consumption and unmanageable overall costs in die-casting finishing workshops.

Solution:
For these issues, we recommend EcoPress Cutting Fluid SF18/BF811—a high-performance, eco-friendly alternative. Its refined mineral oil and synthetic ester formula delivers exceptional lubrication and extreme-pressure performance, meeting diverse material and machining needs while fully replacing oil-based cutting fluids.
Why Choose EcoPress Cutting Fluid SF18/BF811?

✔ Superior oxidation resistance, rust prevention, and anti-foaming properties make it ideal for die-cast part machining.
✔ Unique corrosion inhibitors for non-ferrous metals (e.g., aluminum & copper alloys), preventing discoloration, corrosion, and mold growth on die-cast parts, rods, and plates.
✔ Balanced rust inhibitors & stable pH, ensuring 7–15 days of inter-process rust protection (low requirement).
✔ Micro-emulsion, low-foaming formula, perfect for CNC horizontal machining centers with non-woven belt增压 (pressure-boosting) systems and high-pressure pumps (up to 7.5 Pa), eliminating foam overflow.
Eco-Friendly & Worker-Safe Formula

✅ Free from chlorine, nitrites, phenols, silicone additives, and heavy metals—fully compliant with EU ROHS environmental standards.
✅ Water-based, low-pH formula—skin-friendly, non-irritating, and safe for prolonged use.
✅ Low volatility & no harmful fumes—no respiratory or oral irritation, ensuring a healthier workplace.
