Foundry Coatings and Repair Materials for Die-Casting

I. Introduction: Coatings and Consumables, the Protective Core of Die-Casting Equipment

 As essential Die casting consumables, they also fall into the category of high-efficiency Metalworking fluids. Through functions like "anti-aluminum adhesion, high-temperature resistance, and damage repair," these products not only Extend die life and durability, reducing equipment replacement costs, but also minimize melt contamination, contributing to Improving casting surface finish. Covering four major categories—boron nitride anti-adhesion coatings, refractory fiber repair mortars, specialized launder coatings, and high-temperature protective coatings—they are adapted to meet all-scenario equipment maintenance needs.

II. Detailed Core Product Analysis

(I) DR-BN 61A Concentrated Blue Boron Nitride Coating — The Core Consumable for Anti-Aluminum Adhesion

1. Product OverviewDR-BN 61A is a crucial Die casting consumable and a high-performance Metalworking fluid, formulated with 97% high-purity BN powder, which forms a stable blue emulsion upon dilution. Its core value lies in creating a dense anti-adhesion film that isolates the aluminum melt from the equipment substrate. This not only Extends die life and durability by reducing wear from aluminum adhesion but also minimizes dross formation, contributing to Improving casting surface finish. As a professional Die casting lubricant supplier, DASEON ensures its suitability for high-frequency die-casting scenarios.

2. Core Characteristics & Application Scenarios

• Characteristics: High-temperature resistance, no iron contamination. Packaged in 5kg pails and 20kg boxes with an 18-month shelf life. As a Metalworking fluid, it remains a stable suspension for 30 minutes after dilution, allowing for uniform application.

• Scenarios: Suitable for melt-contact parts such as the inner walls of ladles, launders, and filter components. After application, it prevents aluminum adhesion, reduces cleaning frequency, and Extends die life and durability. It also ensures melt cleanliness, enhancing the effect of Improving casting surface finish.

3. Usage & Selection

• Usage: Dilute according to the application scenario (nozzles 1:2, porous materials 1:3~4, spraying 1:4~5). After brushing or spraying, gently wipe the surface. Reapply periodically and avoid thick coats that may crack.

• Selection: Prioritize for high-frequency melt-contact parts. Use the 20kg box for mass production and the 5kg pail for smaller batches, aligning with the cost-effective solutions of a Die casting lubricant supplier.

(II) DR-INS 1150 Refractory Fiber Mortar — Emergency Equipment Repair Consumable

1. Product OverviewDR-INS 1150 is an essential Die casting consumable and a functional Metalworking fluid, based on aluminosilicate fiber cotton compounded with high-temperature binders. Its advantages are its easy moldability and strong adhesion, allowing for the quick repair of cracks and preventing the need for complete equipment replacement, which directly Extends die life and durability. The repaired surface is smooth, reducing melt adhesion and indirectly contributing to Improving casting surface finish.

2. Core Characteristics & Application Scenarios

• Characteristics: Low shot content, high-temperature resistance (≤1150℃), and stable dimensions at high temperatures, making it suitable for die-casting equipment working environments. As a Metalworking fluid, it can be mixed into a paste as needed to suit different damage scenarios.

• Scenarios: Repairing leaks at launder joints, spalling on the inner walls of ladles, and defects on custom-shaped parts. Post-repair, it prevents melt leakage, which Extends die life and durability, and avoids impurity contamination, ensuring Improving casting surface finish.

3. Usage & Selection

• Usage: Moisten tools with water to prevent sticking. After cleaning the damaged area, moisten it with a 20% silica sol solution. Mix and apply the mortar at a ratio of "dry powder:water = 1:0.3~0.4". After drying, DR-BN 61A can be applied to enhance anti-adhesion properties.

• Selection: For small cracks, use "mortar + water." For high-temperature, load-bearing areas, use "mortar + silica sol." For a quick return to production, a drying apparatus can be used, in line with the scenario-based recommendations of a Die casting lubricant supplier.

(III) LD-210 Launder Coating — Launder Micro-Damage Repair Consumable

1. Product OverviewLD-210 is a precision Die casting consumable and a targeted Metalworking fluid, based on siliceous materials, specifically designed for repairing fine cracks in launders. It fills micro-cracks and smooths the surface, preventing minor damages from causing major failures, thus Extending die life and durability. It also reduces the flow resistance of the melt, directly contributing to Improving casting surface finish.

2. Core Characteristics & Application Scenarios

• Characteristics: High-temperature resistance (1200℃), good fluidity (easily penetrates micro-cracks), and a smooth surface after drying. It has strong compatibility with launder substrates.

• Scenarios: Repairing cracks on the inner walls of launders, micro-cracks on nozzles, and wear on the pouring spouts of ladles. Post-repair, it prevents melt from stagnating and cooling, which Extends die life and durability, and ensures smooth melt flow, enhancing Improving casting surface finish.

3. Usage & Selection

• Usage: After cleaning the launder, brush micro-cracks 2-3 times. For large areas of wear, spray (thickness 0.1~0.2mm). After drying, apply DR-BN 61A. For cracks wider than 1mm, first patch with DR-INS 1150, then use this product.

• Selection: Prioritize for siliceous launders. For ceramic fiber launders, use with a silica sol. Choose 1kg/5kg packs for small batches and 20kg packs for large batches, in line with the specification matching of a Die casting lubricant supplier.

(IV) DR-25 Series High-Temperature Protective Coatings — Specialized Tool Protection Consumable

1. Product OverviewThe DR-25 series are specialized Die casting consumables and dedicated Metalworking fluids, available in DR-25A water-based (resists 250℃) and DR-25C oil-based (resists 1600℃) versions. They provide a dense protective film for anti-oxidation and anti-adhesion, which not only Extends die life and durability by reducing tool wear but also protects the tool surface, contributing to Improving casting surface finish.

2. Core Characteristics & Application Scenarios

3. Usage & Selection

• Usage: Clean the tool, then stir the coating. DR-25A can be directly sprayed (thickness 0.15~0.2mm). DR-25C can be brushed or diluted for spraying (thickness 0.2~0.3mm). Use after drying.

• Selection: Choose DR-25A for scenarios ≤250℃. Choose DR-25C for scenarios >250℃ or multi-metal applications. Use 25kg pails for mass production and 5kg pails for small batches, in line with the precise matching of a Die casting lubricant supplier.
