our history
year 2001, two engineers, humbly started up a small company, spheretek industry, collecting cenospheres from power companies' flyash reservoirs. we learnt how to dry up the wet material and sieve to remove the large particles and foreign matters. the same year first deal was signed and the first container load was delivered to customers.
year 2002, we moved to a new location as business expands. we learnt how to separate different particle size to make different product. we introduced the 150 microns to customers. year 2003, as we expand our sourcing range we learnt how to make different product based on color, density, particle size range. year 2005, inspired by 3M's glass bubble, we began to study possibilities to synthetically manufacture low cost, high strength hollow microspheres in industrial scale with consistent specs much much higher than cenospheres. year 2006, we moved to the current location where we registered a new company name sun microsphere co., ltd as our manufacturing base. Year 2016, after more than ten years of studying and testing we successfully set up a pilot plant where high quality hollow glass microsphere is made. Year 2017, An industrial scale production line is in going on at a new location in the city's hi-tech developmental zone. Year 2018, Sun microsphere co., ltd is replaced with a name Hongwei Advanced material co., ltd at the new location. we understand this is only the beginning and we'll keep studying more possibilities and introducing more new products to you. |
