Diecast mold

The history of die-casting dates back five thousand years. At that time, plaster, stone, and sand were used to make patterns and molds. The first die-casting design dates back about 200 years, and the method developed significantly in the 20th century. The first die-cast parts were used in the printing industry.

Die casting is used to cast metals with low melting points, such as aluminum, zinc, and recently brass. Die casting is a combination of the words “die” and “casting” and means casting under pressure. This method is not suitable for metals with high melting points because existing steels cannot withstand temperatures above 600 degrees Celsius, at which point they lose their hardness and deform under erosion and pressure. Die casting is a suitable method for mass production of metal parts, and mold design is of particular importance in this process.

In the die casting process, molten metal is injected into molds under pressure. This requires high pressure, which requires precise mold features and specifications. The principles of die casting mold design are of great importance because they affect the shape, quality, and integrity of the final product. Incorrect design can lead to damage to tools or materials and reduced product quality, while effective design can improve efficiency and production time.

Types of die casting machines 

Die casting machines are divided into two types: hot chamber and cold chamber. In hot chamber machines, the material is melted inside the machine chamber and transferred to the mold with the help of a jack. These machines are designed for continuous production. In cold chamber machines, the material is melted inside the crucible and transferred manually or automatically to the machine cylinder and then injected under pressure into the mold.

Die casting molds are used to produce industrial parts. The design of these molds is determined by the final shape of the product and other factors. Factors that should be considered in the design of a die casting mold include slopes, stripes, parting lines, embossing, grooves, vents, and symbols. These features affect the quality and useful life of the mold.

Die casting mold life 

Several factors affect die life, including thermal fatigue, proper material selection, and optimization of cooling systems.

Advantages and disadvantages 

Die casting has many advantages, including producing high-precision parts and requiring little machining, but it also has disadvantages, such as not being applicable to metals with high melting temperatures and high investment costs. Aluminum is one of the most important metals used in this method and has wide applications in various industries.

Plastic injection mold

Plastic injection molds also have their advantages, including speed and high accuracy. These molds can be made with the help of CNC machines, which provides high accuracy in the production of parts.

Conclusion:

Die casting is one of the most widely used methods for producing metal parts, and is particularly used for manufacturing aluminum parts. Die casting requires an experienced team to manage its complexities and produce quality parts.
