In general it is advisable to use a hole size larger than the material thickness. The closer the hole size and material thickness come to a 1 to 1 ratio, the more difficult and expensive the process is. Dependent on the material type, smaller hole size to material ratios can be achieved. The minimum diameter we can fabricate is 0.003" (0.08mm). If you require a die that isn't already in our die bank, our experienced tool and die makers can quickly make exactly what you need at a reasonable cost. Margins
Margins are the blank area along the edges of the sheet. If you want the product with special margins, you should provide the width of each margin on all four sides (measured from the edge of the sheet to the edge of the first hole).Manufacturing considerations may affect margins. If the margins requested are not possible .We will replace it with the similar products as your consideration.
