Investment Casting – Leesh Holdings – Various Alloy Material

Investment Casting by Leesh Holdings

Leesh Holdings provides top – notch investment casting services across various industries such as mining, agriculture, material handling, and automotive.

Alloy Materials

We utilize different kinds of alloys. For American standards, common alloys include 304 and 316 stainless steels (ASTM A276), which are known for corrosion resistance. In the aluminum series, 6061 – T6 (ASTM B221) is popular for its strength – to – weight ratio.

For European standards, stainless steels like X5CrNi18 – 10 (EN 10088 – 1) are widely used. Aluminum alloy EN AW – 6082 (EN 573 – 3) is common for its good formability and mechanical properties.

In terms of Australian standards, alloys such as AS 1538.6 Grade 304 and AS 1538.6 Grade 316 for stainless steels follow similar corrosion – resistant properties as their international counterparts. Aluminum alloy AS 1666.1 6061 is also frequently used in various applications.

These alloys, combined with our investment casting expertise, ensure high – quality components for different industrial needs.

Investment casting, also known as lost wax casting, is a casting method in which a pattern is made of a melt-able material, then coated with several layers of refractory material to form a shell, and the pattern is melted away after high-temperature firing, and then the molten metal is poured into the shell.

Investment casting have high precision and high surface quality, with small machining allowances, which can achieve less or no machining requires. Investment casting can cast complex thin-walled parts with complex shapes (the minimum wall thickness can reach 0.25-0.4mm), and the smallest hole diameter can reach 2.5mm.

The process normal as below:

Drawing Review ->Tooling Designing ->Tooling Manufacturing ->Wax Pattern Making ->Pattern Tree Assembly ->Dipping and Coating ->De-waxing and Firing- Pouring-Knockout ->Grinding ->Heat Treatment -> Machining(if requires) ->Inspection->Delivery
