We Offer Pcd Wire Drawing Dies. Pcd Dies are Used to Draw Both Ferrous and Non-ferrous Metals At Both High and Low Speeds Due to Its Quality of Thermal Conductivity Which Enables It to Observer the Heat, Which Generates While Drawing, from the Die Bore and also Helps the Die to Maintain Its Diameter for a Longer Time. P.c.d. Blanks are Available in Different Grain Sizes I.e. 3 Um, 5 Um, 25 Um, 50 Um Which Ajex Chooses Itself According to the Customers' Demand or Their Preference. Now a Days, Wire Drawing Units are Preferring the Use of P.c.d. Wire Drawing Dies Instead of Natural Diamond Dies Except in Some Special Cases Due to Life & Re-boring Capacity Obtaining from P.c.d. Dies. pdc Die :polycrystalline is a Kind of Synthetic Material Which Combines the Advantages of Perfect Surface Finish, Minimum Friction and High Wear Resistance. diameter of Hole : 0.20-12.00mm dies Advantages :good Durabilityhigh Efficiencygrain and Nib Sizescrack Proofsmoothnessdurability Predictedapplications :nonferrous Wire, Including Copper, Aluminum, Electromagnetic Wire and Stainless Steel u - Ultra Fine, F - Fine, C - Coarse addmaamerican Diamond Die Manufacturers Association. maximum Hole Size for Hard Wire is Using a 12o Reduction Angle and 30% Bearing Length.
