Say goodbye to sand core defects!

Three Core Defect Root Causes & Systemic Solutions
1. Sand Core Deformation: Precise temperature control + balanced curing to eliminate dimensional deviations.
2. Sand Core Porosity: Optimized venting + strict control of gas generation to eliminate casting gap defects.
3. Sand Core Looseness: Stable pressure sand injection + uniform filling to improve sand core compactness.
Case Study: Domestic Valve Factory's Fully Automated Core Shooting Line Upgrade Increases Capacity by 2.3 Times.
A professional valve casting company in China, which mainly produces various industrial valve castings,
faced three major pain points with its original traditional semi-automatic core shooting production line
high sand core defect rate, high labor costs, and insufficient capacity to meet the demand for large-volume orders.
In addition,
the product precision was unstable, limiting the acceptance of high-end orders.
