Mold release is a critical step in the die casting process, ensuring that precision metal components eject from the die effortlessly and free of defects.
What is Mold Release?
Mold release, also known as die spray or die lubricant, is a liquid that is applied to the steel mould before each shot of molten metal. The liquid evaporates when it comes into contact with the hot steel, leaving behind a thin, lubricated coating. This coating helps to prevent the metal from sticking to the mould, making it easier to eject.
Why is Mold Release Important?
Mold release is important for several reasons:
- It prevents the metal from sticking to the mould, which can cause defects in the finished part.
- It helps the metal to flow more freely into the mould, resulting in a more accurate casting.
- It reduces the amount of force required to eject the part from the mould, which can extend the life of the mould.
- It can improve the cosmetic finish of the part.
Types of Mold Release
There are many different types of mould release available, each with its own advantages and disadvantages. The type of mould release that is best for a particular application will depend on the type of metal being cast, the complexity of the part, and the desired finish.
- Water-based mould releases are the most common type. They are relatively inexpensive and easy to use. However, they can be less effective than other types of mould releases in preventing porosity.
- Oil-based mould releases are more effective at preventing porosity than water-based mould releases. However, they are more expensive and can be more difficult to use.
- Silicone mould releases are a good choice for parts that require a high-quality cosmetic finish. They are also effective at preventing porosity. However, they can be more expensive than other types of mould releases.
Mold Release Concerns
There are two main concerns that customers typically have about mould release:
- Will mould release cause porosity?
- Is mould release safe for medical and surgical applications?
Porosity is a natural occurrence in the die casting process. However, the amount of porosity can be minimised by using the right type and amount of mould release. Dynacast works with customers to select the mould release that is best suited for their specific application.
Mold release can be safe for medical and surgical applications if it is properly applied and the part is properly cleaned after casting. Dynacast works with customers to ensure that their mould release is safe for their specific application.
