Natural Mica Packing For Transistors To220, To 3

The term 'Fabrication' applies to operations, such as: cuttings, stamping and punching of natural sheet mica to specified size, shape, thickness and design within close dimensional tolerance for electrical and electronic end-users.
Normally, mica is fabricated with compound dies by foot or power punch process, especially if the finished piece contained perforation of any kind. A compound die punches the outside shape and all the inside holes with one stroke of the press most accurately. The compound die necessary for stamping natural sheet mica may be grouped in two general categories. One category comprises the highly complex dies required to produce Mica Spacers containing a number of perforations in various sizes and shapes for use in electronic tubes. The extremely critical dimensions and spacing of the perforations can be obtained only with fully designed and accurately constructed dies.
The Transistor washers very common are : TO 220, TO3,TO3P,TO3PL, TO247 etc.

Fabricated Mica for Electronic components:-
Fabricated Mica applies to cutting & punching of natural mica sheets to a specified shape and thickness for electrical and electronic end-uses. Most of the fabricated mica mechanisms are custom built against provided specifications and drawings. The fabrication is performed by using foot or power presses with the help of compound dies. The mica may also be hand-sheared & drilled.
