High-Pressure Die Casting RLT-6620

RLT-6620 is ready-to-use white emulsion high-pressure Die Casting Release Agent made of premium pure raw materials with precisely balanced wax additives, customized for aluminum and zinc alloy high-pressure die casting production lines below 1600 tons. Its exclusive compound formula stabilizes casting shrinkage during metal solidification, delivering stable demolding performance even on aging, worn or cracked high-pressure molds.

Castings produced with RLT-6620 feature ultra-smooth, bright and precise surface finish under high injection pressure. The residue-free surface eliminates defects in subsequent post-processing including welding, liquid painting and powder coating, greatly reducing reject rate for high-pressure foundry manufacturers.

This release agent adopts micro-fine emulsion technology with outstanding long-term stability for continuous high-pressure casting. After weeks of standardized spraying on high-pressure production lines, no sticky buildup forms on mold frames, inner cavities, sliding cores and spray gun nozzles, cutting frequent equipment cleaning downtime.

Application Scope

RLT-6620 is universal wax-containing high-performance release agent exclusively designed for high-pressure die casting equipment below 1600T. Standard daily production dilution proportion ranges from 1:150 to 1:200.Stable mold temperature range for high-pressure casting covers 140°C up to 350°C, compatible with all conventional aluminum and zinc alloy high-pressure cast parts of different sizes and structural complexity.

Optimal dilution ratio must be adjusted according to actual high-pressure production conditions, including spray duration, spray flow velocity, casting geometric complexity and mold operating temperature. We recommend customers conduct small batch on-site trials to confirm the most suitable mixing proportion for individual high-pressure casting lines.

FAQ

1. What tonnage high-pressure die casting machines is RLT-6620 suitable for?

   This wax modified release agent is developed for high-pressure casting production machines below 1600T, widely matched for small and medium aluminum zinc alloy high-pressure casting equipment.

2. What is the standard dilution ratio of RLT-6620 for high-pressure die casting?

   General mixing ratio is 1 part release agent mixed with 150 to 200 parts clean water; adjust concentration according to mold temperature and casting complexity after field test on high-pressure lines.

3. Can high-pressure castings made with RLT-6620 be directly welded and powder coated?

   Yes, balanced wax formula leaves ultra-thin removable isolating film, no residual interference for welding, liquid painting and powder coating procedures of high-pressure casting parts.

4. Will this release agent cause nozzle clogging and mold residue buildup on high-pressure casting equipment?

   Micro-fine emulsion structure avoids nozzle blockage, long-term continuous high-pressure production will not form sticky wax or carbon deposits on mold frames, sliding cores and mold cavities.

5. What mold temperature range can RLT-6620 withstand stably during high-pressure die casting?

   Stable operating mold temperature range is 140°C to 350°C, and it still works well on slightly cracked and aging high-pressure molds.

6. How long is the shelf life of RLT-6620 high-pressure die casting release agent?

   Sealed storage under cool shaded environment can guarantee 12 months of stable emulsion state without stratification or deterioration.
