Converting from Aluminum Machining to Aluminum Squeeze Casting

The transition from aluminum machining to aluminum squeeze casting provides valuable opportunities to improve product quality, reduce production costs, and simplify the production process. Squeeze casting combines the advantages of casting and forging, producing parts with minimal porosity, high dimensional accuracy, and high strength. Traditional machining generates waste and requires more time, while squeeze casting is different as it can produce parts close to the near-net shape, reducing material loss and improving production efficiency.

Why Some Machining Applications Need to Be Replaced

For a long time, traditional machining methods such as milling and turning have been used to produce precision aluminum parts, but these methods come with limitations, making alternative methods such as squeeze casting more attractive:

Material Waste

Machining usually requires cutting off a large amount of aluminum, resulting in high material costs and increased waste.

This is particularly costly for complex parts, with material loss reaching up to 60-70%.

In contrast, squeeze casting can produce parts that are near-net shape, greatly reducing waste.

Time Consumption

Machining complex shapes takes a long time, and each cutting increases the production cycle.

Additional finishing, like polishing, will further extend production time. This slows down the delivery speed, increases costs, and makes it difficult to meet tight deadlines.

Why Squeeze Casting Can Replace Machining

Squeeze casting combines the advantages of precision casting and high-strength forging, making it a powerful alternative to traditional machining:

Material Efficiency

Squeeze casting can produce parts that are close to the near-net shape, minimizing material waste and the need for additional machining.

This makes it a more cost-effective option, especially when using expensive alloys.

Suitable for Large-Scale Production

Squeeze casting only requires one operation to quickly produce high-quality parts. This efficiency can reduce labor costs and shorten delivery times.

In addition, squeeze casting can ensure consistency of all production components and maintain a unified specification that is crucial for large-scale production.

Cost Reduction

Squeeze casting can lower production costs by reducing material waste and the need for further machining.

It also shortens production times, making it a cost-efficient choice for large-scale manufacturing.

Design Flexibility

Squeeze casting makes it easier to produce products with complex shapes that are challenging for mechanical processes.

This allows for more optimized designs in industries where reducing weight and improving strength are critical.
