| Ceramaret is the leader producer of output guides for dot matrix printheads. Sold worldwide to printers and printheads manufacturers, they are also widely used by printhead repair companies. To meet the market demand, Ceramaret manufactures for over 20 years large quantities of monobloc zirconia guides. From 7 holes in-line to 2 x 40 holes staggered, with hole Æ >0,22 mm (>.0087"), almost any hole configuration is available. %20by%20Ceramaret_files/image004.jpg) Selection and Quality Ceramaret produces a very large selection of standard guides but also a range of replacement guides for the printhead repair market, offering improved quality over the original guides usually made out of plastic. Quality is not only reflected in the lifetime of the printhead but also in the print quality which is a very important parameter, mostly for NLQ and barcode applications. Typical Characteristics | | | Hole diameter | 0,21 to 0,57 mm (.0083" to .0224") | 0,22 to 0,384 mm (.0087" to .0151") | | Hole tolerance | +10 / -5 mm (+.0004" / -.0002") | +/- 10 mm (+/-.0004") | | Vertical pitch (non-cumulative) | +/- 10 mm (+/-.0004") | +/- 10 mm (+/-.0004") | | Horizontal pitch (2 rows) | +/- 15 mm (+/-.0006") | +/- 15 mm (+/-.0006") | | Length | +/- 100 mm (+/-.004") | +/- 100 mm (+/-.004") | | Width (1 row) | 0/-150 mm (0/-.006") | 0/-150 mm (0/-.006") | | Thickness | +20/-10 mm (+.0008"/-.0004") | +/-25 mm (+/-.001") | Quality Assurance The quality assurance procedure is the same for two or three parts ruby or for the zirconia guides. Procedure described hereunder is for the final inspection. Intermediate measurements and visual inspection are also carried out during manufacturing. | | | Hole diameter Go / No go | pin gauges | AQL = 1,5% | AQL = 1,5% | | Length Horizontal | Micrometer | AQL = 2,5% | AQL = 2,5% | | Width Horizontal | Micrometer | AQL = 2,5% | AQL = 2,5% | | Thickness and parallelism | Vertical micrometer | AQL = 1,5% | AQL = 2,5% | | Depth of the grooves | Shadowgraph 100 X | AQL = 1,5% | NA | | Profile geometry | Shadowgraph 100 X | AQL = 1,5% | NA | | Hole location | Shadowgraph 50 X | AQL = 1,5% | AQL = 1,5% | Visual | Cracks, chips, surface finish of the holes and transition radius.
