prototype cnc machining with PEI
Jan 24, 2019

During this time, a customer from the United States asked me which materials were transparent and resistant to high temperature. For transparent materials, I immediately thought of several transparent materials commonly used as prototype companies: acrylic, PC, transparent ABS. Then I asked the customer how much the temperature would last, and the customer gave the 125C standard, so I chose PC, because it was closest to the temperature. So I recommended using PC to make her board. But when customers use it for laser testing, the PC still doesn't work. Later, after discussion with engineers, it was decided to use glass materials-BK7 or quartz glass (fused quartz).


BK7: is a BK9, with excellent mechanical properties, very low bubble and impurity, and good scratch resistance. Due to its stable chemical properties, there is no need for special processing grinding and polishing. It is used in many fields, such as optoelectronics, microwave technology, diffractive optical elements and so on. The standard values of thermal properties are: softening point 719 °C, annealing point 657 °C, strain point 624 °C. Quartz glass: quartz glass is a special kind of glass containing only one component of silica. Because of the different kinds, processes and raw materials, foreign countries are often called silicate glass, quartz glass, fused quartz, synthetic fused quartz, and transparent, translucent, opaque quartz without clear concept. Used in the manufacture of semiconductors, electric light sources, semiconductors, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment and chemical instruments resistant to high temperature and corrosion, chemical, electronic, metallurgical, building materials and national defense industries, It is widely used. It can be used for a long time at 1100 ℃.
