Headline: Losing ¥100k Daily from Downtime? Pitfall Avoidance Guide for Aluminum/Magnesium Die Casting Release Agents—Save 5%+ Net Profit with 3 Steps
In aluminum and magnesium die casting, mismatched or poorly selected release agents lead to carbon buildup, sticking, and dull workpieces. Today, KZY acts as your "die casting release agent specialist" to prescribe solutions in three steps—
First, align release agent selection with your die casting conditions (part geometry, alloy type, machine tonnage, mold temperature, cooling efficiency, post-casting processes, and specific requirements). This ensures better adaptability and performance—like a doctor prescribing medicine after assessing age, body temperature, phlegm color, nasal discharge, and cough severity.
Temperature is critical—die casting boils down to three stages: melting, filling, and solidification. Key parameters include molten aluminum temp, pre-spray mold temp, post-spray mold temp, mold heater settings, and how spray duration affects temp. Temperature dictates >70% of release agent selection, especially heat resistance.
Example: Molds at 300°C vs. 200°C require vastly different heat-resistant agents. For high-temp scenarios (>300°C)—common with large machines (>1,600 tons), poor cooling (hard water, cost constraints), or recycled agents—prioritize high-temperature-resistant release agents.
Analyze part geometry (thickness, depth), alloy grade, machine tonnage, and post-processing needs (e.g., anodizing favors silicon-free agents). Like treating a child vs. an adult with similar colds—tailor solutions to the workpiece’s "resistance."
Understand existing issues: current agent performance (sticking, cleaning difficulty), and defects. Like asking about drug allergies or prior treatment efficacy.
Case Study: A auto parts plant using a standard agent for engine blocks faced sticking near gates due to 380°C mold temps and poor cooling. Switching to Kezhiying 6301 high-temp agent reduced sticking by >70%; process optimization eliminated gate sticking.
Select agents based on conditions—no blanket solutions (like overprescribing antibiotics).
Match Conditions: Prioritize heat resistance, lubrication, carbon control, and cleanability. Avoid two pitfalls: assuming foreign brands outperform domestic, or that higher price = better quality. Focus on value—suppliers should offer alternatives to expensive imports, especially amid fierce EV competition.
Heat Resistance: For molds >300°C (with poor cooling), use high-temp agents; for 180-240°C, general-purpose suffices.
Lubrication: Ensure deep-cavity demolding.
Carbon Control: No "zero-carbon" agent exists (organic-based agents carbonize). Aim to reduce buildup and cleaning time.
Cleanability: Balance demolding (strong adhesion) and post-painting cleaning (weaker adhesion).
Match Specifications: After condition matching, align with solid content (10%-40%). Use refractometers (or ovens for accuracy) to test content—critical for dosing and quoting.
Match Pricing: Cost depends on conditions, raw materials, solid content, usage, logistics, packaging, and payment terms. Example: 20% solid agent shipped to Jiangsu/Zhejiang costs more than 5 tons to Northeast China.
Concentration ≠ Absorbance: Comparing absorbance across brands is flawed—raw materials vary. Test based on solid content for accuracy.
Dilution Ratio ≠ Fixed Rule: Supplier recommendations (e.g., 1:100) are starting points. Adjust for conditions: higher dilution for simple parts/long spray times; lower for complex parts/short times.
⚠️ Beware of Quackery: Reject claims of "zero carbon," "100% cleanability," or "universal" agents.
