Q1: Are you a manufacturer or trading company?
"We are a manufacturer of wire drawing dies,our factory is located in Tianchang city, Anhui province where is 2 hours-driving from Nanjing airport"
Q2:what can you buy from us?
Natural Diamond Drawing Die(ND drawing dies)
polycrystalline drawing die( PCD drawing dies)
Tungsten Carbide wire drawing die(TC drawing dies)
Synthetic single crystal diamond wire drawing die (SSCD drawing dies)
Monocrystalline wire drawing die (MCD drawing dies)
Nano wire drawing die
Q3:What determines the sizing length of the wire drawing die?
"The sizing area determines the surface quality and wire diameter of the wire. The sizing length (L) is usually about 20% to 50% of the nominal wire diameter (?). However, this percentage depends on the wire material, drawing process, and drawing specification."
Q4:How can I extend the uptime of my wire drawing machine?
"Use a quality wire feed/rod and properly maintain your machine and lubricants. Choose the best wire drawing die material, use the correct sequence of die sizes, and use the proper internal geometry (corners and sizing bands) to match the wire alloy you are drawing."
Q5:Wet drawing: How to maximize the life of the drawing die?
"Maintain lubricant concentration and temperature within supplier recommended parameters. Failure to do so will reduce lubricity and lead to increased die wear. Make sure your filtration system is functioning properly to keep your drawing lubricant clean. Ideally, ensure that the lubricant nozzle is pointed toward the entrance of the drawing die to keep the entrance part of the drawing die clean and prevent the die from clogging. Make sure the wire enters and exits the mold as vertically as possible to prevent uneven wear on the mold."
Q6:How do wire drawing dies compare to rolling dies?
"Wire drawing provides better dimensional control because wear only changes its cross-sectional area. Wire rolling forces can cause the gap between rolls to change, causing the rod or wire to change its shape."
Q7:How to check the drawing mold?
"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."
