Precision casting, also known as investment casting, plays a vital role in the manufacturing of engineering machinery parts. This specialized casting process allows for the production of complex and intricate parts with high precision and quality.

Learn about the investment and casting process used in manufacturing metal components.

Over 130 investment casting enterprises showcased silica sol casting, 3D printed wax patterns and intelligent production lines at the 24th China International Foundry Expo. The industry shifts toward aerospace, medical and new energy high-end castings, stepping into micron-level precision manufacturing with simulation technology cutting product defects greatly.

Adopting both investment casting and sand casting technologies, the enterprise supplies castings to over 20 European and American countries for construction machinery, energy, shipbuilding and rail transit. Its one-stop dual-process solution cuts clients’ machining costs and boosts part interchangeability, driving growing repeat orders. The firm upgrades eco-friendly production lines and offers free process evaluation. Industry insiders believe manufacturers mastering both casting processes hold an upper hand in global high-end casting trade and help upgrade China’s casting industry to high-value production.

Junlong Machinery upgraded the shell-making procedure of silica sol investment casting. By improving wax cluster structure, dipping and air-drying control, we reduced deformation and sand inclusion defects and greatly improved the product yield. We supply one-stop casting and machining services for global clients.

Investment casting fabricates integrated parts with thin walls, undercuts and hollow cavities. Compatible with superalloys, titanium and refractory metals, it cuts machining and material waste, offering better overall cost for small-batch complex components.
