Abstract
PURPOSE: An impact-type plastic printing type of computer serial printer is coated with paraffin on the region not be plated and then dipped into plating solution. The plastic type will need partial plating only, thereby to effect longer useful life.
CONSTITUTION: A polyacetal resin type base 1a having print section 1b and spring 2 is first activated on the whole surface 1a and 1b and then coated with paraffin layer in thickness of 10 to 50 microns, excepting the printing surface. The paraffin- coated type is then wholly dipped into Ni plating solution until is has a 50 micron thickness of plating 4. The paraffin-coated region 3 has no plating metal which may otherwise fall by impact. As there is no such falling metal fragments, the type withstands damage after 10,000 printing use.
