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.
The selection of aluminum die casting release agent mixer needs to be determined according to specific needs and application 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.
We can summarize the following possible aluminum die casting release agents and their characteristics, aluminum die casting release agent mixer formula and process and the role of mold release agent.
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.

- Water-based aluminum die casting release agent
- Aluminum die casting release agents based on organic solvents
- Aluminum die casting release agents provided by MetalFlow
- Other innovative release agents
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.
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.
The role of mold release agent
The role of mold release agent in aluminum die casting process includes:
- Forming an isolation layer on the mold surface to prevent direct adhesion of aluminum alloy to the mold.
- Improving the surface quality of castings, reducing scraping and defects.
- Extending mold life and reducing maintenance costs.
Prevents metal adhesion and reduces the risk of die sticking
Release agents form a thin lubricating film on the mold surface, preventing the molten metal from directly contacting the mold steel and sticking to the mold, leading to die jamming or strain. This function is fundamental in die casting.
Improves pouring fluidity and facilitates metal filling
By reducing the coefficient of friction between the metal and the mold, release agents help the molten metal flow more smoothly into small grooves and thin-walled areas, improving filling integrity and reducing defects such as cold shuts and underfill.
Improves casting surface quality
Release agents inhibit the formation of oxide films or residue adhesion on the mold surface, resulting in a smoother, scratch-free surface and reducing the cost of subsequent machining or polishing.
Extends mold life
By reducing direct impact and wear from the metal on the mold, release agents reduce thermal fatigue and mechanical wear, significantly extending the mold’s service life.
The choice of aluminum die casting release agent depends on the specific application requirements, such as whether an environmentally friendly product, cost control, high temperature stability or specific lubrication performance is required.
