Hartford Technologies has 80+ years of precision ball-making knowledge and is now utilizing that knowledge in the miniature ball market. Hartford Technologies has opened a new facility in China to expand the manufacture of their line of miniature precision balls. The new facility will process chrome (52100/GCr15) or 440C balls from 1mm to 3mm and from grades 10 to 50. The plant is ISO 9001 certified and can process 100 metric tons of balls per year.
Grade 10 balls have a sphericity of only 10 millionths (0.00001”) of an inch and are the highest precision balls that we manufacture. Hartford Technologies provides billions of these precision balls to numerous industries such as automotive, medical, electronics and any other applications where small ultra-precise balls are needed.
Hartford provides precision balls for the most demanding applications. Its customers can expect the same quality and delivery on these smaller balls as on our other precision ball products.
