High Pass Rate Fiberglass Mesh Filter Screen Refractory Cloth Foundry Filter for Aluminum

SPECIFICATION

FEATURES
Brings down the casting rejection rate due to slag inclusions.
Cheap and cost effective,easy installation.
Do not change molten metal element or contaminate molten aluminum.
Stay away from molten aluminum and easy to handle the aluminum scrap recycling (Fiberglass mesh can float on top of the molten metal when the metal is recycled and can be scooped out), this can greatly reduce cost.
Reduces molten metal turbulence,improves molten metal distribution and flow.
Remove oxides and inclusions to improve castings mechanical properties and surface finish.
Excellent stiffness and toughness,good impact resistance.
Mesh and grid is well organized and highly integrity.

APPLICATION
As the first step filtration for primary smelting
Ingate filtration for sand casting,gravity casting or low pressure die casting
As the removal plane to help riser easily to be knock off from castings

How we ensure the filters quality

NINGXIN  has a unique inside quality control flow that give it a distinct  advantage over other foundry filter suppliers, which enabling us to  deliver the highest available quality of foundry molten metal filters.  Founded by a renowned leader in molten metal filtration industry and  with a team of experts in the field, NINGXIN provides extensive and  unmatched filters design and application information for its customers,  generating huge casting industry filtration cases and data. 

To ensure the consistant filter quality, NINGXIN employs the best  technology available today. The company focuses on quality and quality  control from beginning to end. The result is unsurpassed quality, and it  starts with experience and Quality Control. We have made simulated  pouring testing and analyzed over 190,000 samples out of produced  various types of filters. Rich experience and strict quality control  standards enable us to achieve the filters quality which is the hallmark of the company.

2 x Medium frequency electric furnace 200 kg: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
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.
