Sintered Mullite Sand And Mullite Powder With Low Thermal Expansion Coefficient

High Quality Sintered Mullite Sand and Flour for Casting and Refractory Products Material with Low Thermal Expansion

1. Production Introduction

Mullite is a kind of aluminosilicate refractory material. It is made of hard clay mineral resources by high-temperature roasting, crushing, screening, Raymond, iron removal and other machining processes.

It has high aluminum content, low iron content, small coefficient of thermal expansion, high refractoriness, stable thermochemical properties and other excellent mullite series sands and powders.

5. Our Package and Loading

Finished package

Our mine company established in 2003,and its trade company ,Qingdao Jinjunxuan International Trade Co.,Ltd,founded in 2018, relying on the group's logistics advantages and rubber trade experience, Jinjunxuan international has been shouldering the responsibility of group logistics business development and model transformation since its establishment.

In 2019,  In view of the fierce competition in the raw material market, we pay more attention to the quality of products and firmly believe in the concept of "quality-oriented, honest operation". We also rely on  mine company technical advantage to develop customized products.

Using our product, the casting is easy to be shelled, not deformed, not easy to shrink, with good finish and high yield. After that, remind the customer not to be greedy for cheap choice of cheap sand so as not to affect the casting finished products.

It is recommended to choose the products of regular mullite manufacturers with reasonable price, quality and more guarantee. We hope that through our efforts and careful service, we can provide customers with cost-effective products and contribute to the development of the investment casting industry.
