A To visually inspect the interior shape surfaces of wire drawing dies that are less than 3125 inches (8 mm) in size, a microscope will be your best choice. For molds larger than 3125 inches (8mm), you can use a magnifying glass.
For a rough check of the diameter we recommend using a caliper needle. If you need a more precise measurement, thread the wire through the mold and measure the wire diameter with a micrometer or laser caliper.

A Contact us and we can help you choose the most economical solution. Basically, the best material depends on the wire you're drawing and how much you're drawing. Please check the comparison page first to see which drawing die material is available for the size you need to draw. Afterwards we recommend:
SSCD and ND molds are excellent choices for manufacturing fine and ultra-fine wires. Single crystal diamond molds offer superior quality, hardness, precision and long service life.
Ferrous metal rod size wire is manufactured using TC molds and used for relatively short production and trial runs.
We strongly recommend that you contact us to help you choose the most economical solution and reduce the total cost of ownership of your wire drawing die.

A Depending on how dirty your mold is, you may need to use degreasers, ultrasonic cleaning tanks, compressed air, and special cleaning papers.
