Manufacturing Process

Craftsmanship Manufacturing

  • Machining Workshop

    Jinhui has its own processing workshop, equipped with 4-axis horizontal machining centers and 3-axis vertical machining centers, as well as conventional machining equipment such as CNC lathes, milling machines, grinders, drilling machines, etc. Professional machining engineers will develop reasonable and efficient machining processes based on customer drawings to ensure product quality meets requirements.

  • Heat Treatment Workshop

    Heat treatment engineers with years of experience will develop processes based on product structure, size, material, etc. to ensure that product quality meets requirements. With the help of Caterpillar heat treatment experts, Jinhui conducted testing and evaluation on the existing heat treatment furnace, and upgraded and modified the furnace temperature uniformity, transfer system, and mixing system to ensure product performance.

Four Advantages of Warm Core Box Shell Forming Process.

Technological Advantages

  • Use pearl sand and environmentally friendly resin. Baozhu sand is spherical, with a smooth surface, high fire resistance, easy to collapse, good stability, and can be recycled. Environmentally friendly resin, free of phenol and formaldehyde, with national invention patents.

  • The sand shell has high thermal strength, and its strength gradually increases during the casting process, which can effectively ensure the dimensional accuracy of the casting; When the casting begins to cool and solidify, the strength of the sand shell rapidly decreases and has the characteristic of good collapsibility.
