1. Уводзіны

Investment casting—also known as the lost‑wax process—extends far beyond steel and nickel alloys.

It thrives in the copper‑alloy world, providing unmatched precision for complex geometries.

Copper‑alloy investment casting combines the thermal and electrical advantages of copper with the design freedom of ceramic molds.

Такім чынам, manufacturers in электроніка, змазваць & бензін, архітэктурны, і марская sectors rely on these castings to meet stringent performance requirements.

Moreover, growing demand for miniaturized electrical components and corrosion‑resistant hardware continues to drive global market growth, projected at 5.2 % CAGR праз 2029.

2. What Is Copper‑Alloy Investment Casting?

In copper alloy Інвестыцыйнае ліццё, a wax or 3D‑printed polymer pattern replicates the final part. After stacking patterns on a gating tree, technicians build up a ceramic shell around them.

Пасля таго, як абалонка вылечыць, they melt out the wax (hence “lost‑wax”), preheat the shell, and pour molten copper alloy.

Пасля застывання, the brittle shell breaks away, revealing a near‑net‑shape component.

This process achieves tolerances as tight as ± 0.1 мм and surface finishes down to Ра 0.8 µm, reducing downstream machining.
