The aluminium die cast release agent mixer bases on the specific composition of the release agent, process requirements and the performance characteristics of the equipment.
What is the aluminum die casting release agent mixer? Aluminum die casting release agent mixer is a kind of equipment used to mix and prepare aluminum die casting release agent. This equipment is usually used to mix various ingredients evenly to produce release agent suitable for aluminum die casting process.
The selection of aluminum die casting release agent mixer needs to be determined according to specific needs and application of aluminium die casting scenarios. The design of the mixer should take these factors into consideration and select the appropriate formulation and process. For example, if an environmentally friendly release agent is required, a boron nitride or waste oil-based formulation can be selected; if efficient lubrication is required, a water-based formulation or a powdered formulation can be selected.
In this article, we will introduce what is the aluminum die casting release agent mixer. And then their characteristics, aluminum die casting release agent mixer formula and process. Next, it will show actual case study.

Water-based aluminum die casting release agent
According to, this release agent is composed of dimethyl siloxane, modified silicone oil, wax components, surfactants, rust and corrosion inhibitors and fungicides, etc. It has environmental protection characteristics and is suitable for aluminum die casting molds. Its preparation method is simple, the raw materials are easily available, and it is suitable for large-scale production.
Aluminum die casting release agents based on organic solvents
It is mentioned that organic solvent-based release agents perform well under high-temperature mold conditions and can form a smooth oily film to reduce carbon deposition on the surface of aluminum die castings. However, this type of release agent may pose potential risks to the environment and the health of operators.
Aluminum die casting release agents provided by MetalFlow
MetalFlow is a company specializing in aluminum die casting release agents. Its products include paralleled water-based castings (such as CASTFLOW), free-flow casting (such as PASSFLOW) and biostable casting (such as BIOSHIELD). These products have the characteristics of optimizing the casting of complex parts, reducing mold residues, preventing clogging and improving mold life.
Other innovative release agents
Some new release agent formulations are mentioned, such as release agents based on modified bamboo charcoal, sodium alginate, beeswax and other ingredients. These materials may have better environmental protection and sustainability, but the specific applicability needs further verification.
The selection of aluminum die casting release agent mixer needs to be determined according to the specific release agent formula and process requirements.
Key Technical Parameters for Release Agent Mixer Selection
Correct mixer selection requires consider process requirements, production scale, and automation level. These parameters guide selection.
Mixing Ratio Range and Precision
- Determine required dilution ratio, e.g., normal release agents 80-120 times, concentrated types up to 200 times
- Ratio control precision should meet process needs, generally within ±2%
- High precision reduces waste and stabilizes casting quality
Flow and Pressure Requirements
- Choose mixer rated flow based on total spray system flow, preserves20% margin
- Outlet pressure should overcome line resistance and meet spray gun needs, typically 0.3-0.6MPa
- For multiple guns operating simultaneously, pressure must remain stable
Automation Interface
- Whether it can link with machine control to automatically adjust ratio based on mold program
- Whether it has fault self-diagnosis and alarm output
- Data recording and traceability capability to meet quality system requirements
Material and Corrosion Resistance
- Release agents are often mildly acidic or alkaline. Liquid-contact parts should be stainless steel or corrosion-resistant plastic
- Seals must resist oil and solvent to avoid swelling and aging
- Should be easy to clean and replace wear parts after long use
Aluminum die casting release agent mixer formula and process
- Water-based release agent
- Powder-type release agent
- Environmentally friendly release agent
- Traditional liquid release agents
- Special purpose release agents
Water-based release agent
A typical water-based release agent formula includes dimethyl silicone oil, modified silicone oil, wax components, surfactants, rust and corrosion inhibitors and other ingredients.Another water-based release agent formula uses waste oil, mineral oil and polydimethylsiloxane as the base materials, and is prepared in combination with composite emulsifiers (such as Span80 and OP-10). It has good high temperature stability, non-corrosiveness and environmental protection characteristics.
Powder-type release agent
Powder-type release agent is composed of polyethylene, polyethylene wax, micronized wax, epoxy resin, etc., and fillers such as talcum powder and alumina are added. It has good heat resistance and anti-adhesion properties.
Environmentally friendly release agent
Water-based release agents prepared with environmentally friendly materials such as boron nitride can effectively solve the demolding problem in the aluminum die-casting process, while improving the mold lubricity and surface quality.
Traditional liquid release agents
Common liquid release agents include LUBRAST 814 ZR, LUBRAST 898NS and LUBRAST 677 WS. These release agents are usually mixed with water and sprayed onto the mold surface to cool the mold and form an isolation layer to prevent aluminum liquid from adhering.
Special purpose release agents
Some release agent formulas also combine natural materials such as bamboo charcoal, sodium alginate, paraffin, etc., and are prepared through a specific process, which has the advantage of long-term storage and use.
