Private Enterprise "PROMSYSTEMS" manufactures glass to metal seal beads of different standard sizes and shapes to order. They are used for the production: sensors, tecs, power semiconductors (thyristors, diodes), feedthrought and other microelectonics.
These are our standard based glasses with a coefficient of thermal expansions (Borosilicate, Soda-Lime, Titanium, etc):
-
2.5-3.8 ppm/C;
-
4.8-5.2 ppm/C;
-
7.2-8.3 ppm/C;
-
9.0-10.5 ppm/C;
-
In the production of glass to metal seals beads, we use glass of exceptional quality, in accordance with the regulatory and technical documentation for each brand;
-
Drawing must be attached.
It is necessary to indicate with limit: 1. Outside diameter; 2. Inner diameter; 3. Height;
For example: Beads (materials what you need) D1 = 3.2 + -0.2mm, d2 = 1.4 + 0.2mm, h = 2.2 + -0.2mm.
-
We are reasdasdady to take on the development of new standard sizes from any glass at the expense of the customer;
