Lost foam casting - the future choice for complex structures

       The lost foam casting technology of Qingdao Zhaoyuqi Machinery Co., Ltd. replaces traditional sand cores with foam models to achieve one-time molding of complex structural parts, opening a new chapter in the casting industry.

Technological breakthroughs

1. 3D printing rapid prototyping

Using polymer foam 3D modeling technology, the development cycle is shortened to 7 days, supporting precision castings with wall thickness as low as 3mm, such as pump bodies, valves, etc. [citation: combined with general industry technology].

2. Environmental protection and cost optimization

No parting and draft angle are required, reducing processing allowance by 20%, while foam gasification leaves no residue, and waste is reduced by 70%.

3. Full process digital monitoring

The integrated MES system tracks mold temperature and metal liquid flow in real time, and the yield rate is increased to 98%.
