What is aluminum die casting mold?

Aluminum die casting mold is a manufacturing process that involves the metal parts production by injecting molten aluminum alloy into a steel mold, called as a die. The molten aluminum is forced into the mold cavity under top pressure, where it solidifies and takes the mold shape. Once the part has solidified, the mold is unlocked, and the cast aluminum part is removed.

Aluminum die casting mold is affordable for high-volume production.  The molds used can withstand 100K of cycles. This durability lowers the production cost. Additionally, aluminum remarkable thermal conduction and corrosion resistance increase the life of the products.

Aluminium Die Casting Mold manufacturing processing

Aluminum die casting molds are manufactured by a professional die casting company, to make high quality aluminum die casting molds that the die casting manufactures must follow the manufacturing procedure and document, such as quality checking list, manufacturing roles, EDM sparking tolerance and so on. Let’s explore the key stages in the manufacturing process:

1. Mold Design and Specification: first thing to make die casting molds will be the mold design, the skilled aluminum die casting tooling designer use some tools to design the tooling. The design will use  Computer-Aided Design (CAD) software to design completely 3D mold drawing, those include part geometry, draft angles, parting line, and ejection system. Cavity and cores, sliders, cooling systems. Etc.
2. Material Selection: Die casting tooling material is important to effect the mold lifetime, compare to plastic injection mold, die casting tooling requirement more high grade of steel. Common steel materials for aluminium die casting molds include H13, 1.2344, 8407, etc. of course the steel selection is depending on the tooling cost budget and the die lifetime requirement
3. Mold Fabrication: Once die casting tooling design and steel ordered, the next step will be die manufacturing, The manufacturing process includes many machining steps, those include CNC machining, drilling, lather machining, tapping, EDM machining, die polishing, welding, gridding and many more. See below some more detail for each machining process.

3.1. Rough Machining: in this step will normally involving hole drilling, screw tapping, milling, rough CNC machining to the cavity and core, This step creates the basic shape of the mold that is why called rough machining.

3.2. Heat Treatment:  once the rough machining finished, then we need to do the heat treatment to the cavity and core, this is purpose is to have cavity and core reaching hardness to HRC 52-56 degree, so that the cavity and the core can wear the aluminum mold during casting process.

3.3. Fine Machining: once the heat treatment was finished, we need to do the stress relief and milling machining (calibrating over size) before fine machining, finish machining includes fine CNC machining, wire cutting, EDM (Electrical discharge machining), polishing, components fitting, in this process, EDM will take the most of manufacturing jobs and time, because most of ribs and corners that requires EDM to get the desired shape.

3.4. Assembly: Once the die casting mold manufacturing jobs and fitting jobs are completely, the moldmaster will assembly all of components together according to design, this include moldbase, cavity and cores, cooling connectors, screws, ejector pins, spure bushing, sliders, and so on.

4. Mold Testing: Once the moldmater finish the assembly jobs, before starting production we need to trial the die casting mold to check the part quality, dimension, surface, and so on. This may take several times fixing and testing until the die casting parts meeting the final requirement.
5. Mold Production: Once the mold is approved by the end customer, then can start massive production, during this time the mold may need do the maintenance and repair. In case of any issues or damage, appropriate repair and maintenance procedures requirement, if your die casting mold storing at our die casting shop we will repair the mold free.

What things we consider during aluminum die casting mold design process

There are many factors should be considered to make a successful and efficient process. Here are the top things to keep in mind:

Material flow and fill

Make sure right material flow and fill within the mold cavity. Design a well-organized gating system, including shape, size, and location of runners, gates, and sprues, to facilitate perfect and uniform filling of the cavity. Consider the molten metal fluidity and flow features to reduce air entrapment, turbulence and defects.

 Part geometry

Analyze the part geometry and design to determine the best mold configuration. Consider factors such as draft angles, wall thickness, undercuts, and other specs that may affect the molds complexity.

Material selection

Consider the choice of mold material based on factors such as heat transfer, mold life, thermal expansion, and other properties.

Parting line and ejection

Determine the best placement of the parting line, where the 2 halves of the mold meet, to reduce flash or excess material. Design right ejection mechanisms, such as slides or ejector pins, to make sure perfect part removal from the mold.

Cooling system

Incorporate a successful cooling system into the mold design to manage the solidification process. Optimize the design and placement of cooling channels to make sure even and efficient cooling of part. Right cooling helps stop warping, shrinkage, and porosity, and contributes to dimensional accuracy and surface finish.

Mold durability and maintenance

Design the mold with simplicity of maintenance in mind. Consider specs such as removable inserts or slide mechanisms that may need regular replacement or maintenance. Make sure that the mold is durable and robust enough to withstand the high forces and temperatures involved in the die casting process.

By considering these important factors in aluminum die casting tooling design, producers can improve part quality; get dimensional accuracy, decrease defects, and better production efficiency.

Important of quality control and future trends

Picking the best process for die casting aluminum mold is important for achieving high standard parts. Quality control plays an important role in ensuring the functionality and durability of die-casting parts.
