Quality Inspection & Experimental Equipments

Equipment

Inspection equipments for ceramic foam filters

2 x Medium frequency electric furnace 200 kg: mainly used for melting high temperature metal solution, and conducting extreme high temperature solution impact test on the filters
2 x Ceramic bending test machines: detecting the room temperature compressive strength of the filters
3 x Muffle furnaces: detecting thermal shock resistance of the filters
Digital viscometer, slurry hydrometer: testing the feeding and stirring process during the production process
Glassware for balance and chemical experiments: used to check the filter mass, bulk density, and drainage method to verify the porosity

Experimental development equipment

Electron microscopy: check the uniformity of the distribution of the filter surface components.
High-temperature load detector, etc.: used for inspection of data such as deformation and expansion at high temperature of the filter.
High-temperature spectrometer, fluorescent X-ray: Check the composition of the filter.
Digital Viscometer, Slurry Hydrometer: Tests the development of slurry and mixing process.
Bench Drying Box: Simulate the working principle of the drying workshop to dry the experimental product.
R&D production line: a production line dedicated to the development of new foundry filter products.
Small shuttle kiln: used to develop product sintering.
