Q1: What is aluminum die casting Tooling?
Dies, or die cast molds, are made from alloy tool steel in at least two sections: the fixed die half (cover half), and the ejector die half. When the die casting machine closes, the two die halves are locked and held together by the machine’s hydraulic pressure. During the die casting process, molten metal is injected at high velocity into the mold (die) cavity to form a die cast part.
Q2: What is the life of aluminum die casting tool?
Cast tooling is maintained to ensure optimal quality and maximum tool life. The exact life of die cast tooling depends on part geometry and complexity, required tolerances, and most importantly – the type of metal cast. In general, Aluminum tooling can last approximately 100,000 shots, while Magnesium tooling lasts 200,000 – 300,000 shots.
Die casting is not a cheap process. Although most businesses term it economical and quick, their description is due to the efficient optimization of die casting. This means that they were able to develop a model that suits their process and enjoy the advantages of the process.
Before developing CAD technology, mold design, and production was a highly costly project due to repeated trials and modifications. However, with CAD technology, it is possible to use simulation analysis to see the true flow of the molten metal during die casting. Therefore, it becomes possible to optimize the mold design and process and reduce costs.
Yes, reusing old molds can reduce the die-cast mold cost. This is only possible when the old mold has a good frame. However, if possible, you should avoid using an old worn-out mold. Instead, when the mold is at the end of its service life, make a replica mold.
Aluminum die casting tooling base consists of the outer periphery of the mold. It contains all the cavities that are included in the mold. The following parts of the mold are held in the base:
The structure is alternated depending on the process being followed and the material being used. There are two types of mold base structures:
The gate used for the casting process also determines the type of mold used. Keeping the gate inside the mold is an important task and must be kept in a specific place. If not placed carefully, the thickness of the walls deviates from the requirements. A mold base helps to keep the gate in place.
High Pressure Die Casting Mold Value
Choosing a material for aluminum die casting toolings depends on a number of factors. These include but are not limited to:
Cost
The affordability of the material is an important factor when making the choice of mold material. The ability of the material to create the mold and deliver the results with greater ROI is considered in the process of choosing mold material.
Material specifications
The specifications of the material are kept in mind for tooling making. The malleability, ductility, resistance to wear, and hardness are some of these specifications. The materials with more of these properties are considered an ideal choice.
The complexity of product design
The product to be designed through the mold is kept in mind for the mold. The complexity of the product can alter the decisions. The product to be created has to be ideal theoretically and hence the choice of the material.
All of these and many more standards like endurance of the pressure of molten material and specifications altogether are to be considered in making the choice.
The aluminum die casting tooling components are the parts that make the mold work. These parts are assembled to create a complete mold and produce efficient results. The key components of the die casting mold are:
Mold bases
The mold base is a structure of the mold. It contains all the components that are assembled together to work. It helps to hold the gates inside the mold and produce better end results.
Pins
The pins are found inside the mold that is used to eject the casted part out of the mold.
Ejectors
The ejector part of the mold is placed on the moving plate. After the complete formation, it ejects the casted part.
Lifters
This moves on an angle to let the ejector remove the casted part. The release of the mold is eased up with the use of lifters.
Bushings
Bushing is placed between the molten metal and the cavity in order to provide reduced friction and easy ejection of the metal part.
Guides
The guides are used to guide the needles when ejecting the casting.
Alignment devices
These devices are used to align all the parts of the mold. The mold is kept consistent with use of alignment locks and other devices.
