PERFORATION COST FACTORS

MATERIAL TYPE : Remember the least expensive material may not be the lowest cost, a higher strength alloy may allow reducing thickness.
MATERIAL THICKNESS : Thinner materials perforate easier and faster.
HOLE SHAPE AND PATTERN : Round Holes, Slots or Square Holes. Size of holes. Staggered or straight line arrangement of holes. For slotted perforation ,specify parallel to length or width. Hole Patterns Round holes are the most economical, 60° degree staggered round hole pattern strongest and most versatile.
HOLE SIZE : Do not go below 1-to-1 ratio with sheet thickness. Stay at 2-to-1 or larger if possible.
BAR SIZE (PITCH) : Do not go thinner than 1-to-1 ratio with sheet thickness.
CENTRE DISTANCE : It controls feed rate and thereby the production rate. If possible, choose a pattern with longer center distance.
OPEN AREAS : Extreme open are proportions tend to increase distortion; if possible, stay under 50%.
MARGINS : Keep side margins to a minimum to reduce distortion. Use standard Unfinished End Margins if you can.
BLANK AREAS : Consider the die pattern when locating them.
