Standard Unit Dies
For Zinc and Aluminum Die Casting How long does it take to remove a die from a press and replace it (die changeover)? “For small dies,” die casters say, “it can take one and a half to two hours. For large dies…two days, three days, sometimes four days.” Downtime like this is unacceptable for die cast- ers. That's why so many of them are now investing in Standard Unit Die Holders for both long and short run zinc and aluminum die casting. 20-MINUTE DIE CHANGEOVERS Standard Unit Die Holders and Replacement Units are “made for each other.” They’re designed and ground to such close tolerances that die casters can remove Replacement Units from the Holders and put new ones in within 20 minutes or less. This cuts down- time and enables a die caster to increase productivity and profitability on both long- and short-run jobs. FOUR TYPES OF HOLDERS You can get four types of Standard Unit Die Holders: Single Unit; Double Unit; Single Heavy-Duty Unit; Double Heavy-Duty Unit. They are precision engineered and constructed of high quality die steels to withstand the increasingly higher pressures and injection speeds
STANDARD REPLACEMENT UNITS Standard and Standard Heavy-Duty Replacement Units are precision made and completely interchangeable when used with their matching Standard and Standard Heavy-Duty Unit Die Holders. Replacement Units are available in D-M-E No. 2, No. 3, or No. 5 Steel. The more popular sizes are carried in stock for immediate delivery.
NO. 5 STEEL A thermal-shock resistant, hotwork die steel (H-13 type). Supplied fully annealed, approx. 200 Bhn (93 HRB), for easy machinability, it can be sub- sequently heat treated to the desired hardness with a minimum of deformation. Ideal for aluminum and most long run die casting applications. DME No. 5 Steel meets or exceeds the acceptance cri- teria established by the NADCA as detailed in Technical Digest
NO. 2 STEEL An AISI 4130 type steel. It is pre-heat treated to approximately 302 Bhn (32 HRC) to withstand the peening effects of flash. Its high-strength steel is ideal for applications where cavity inserts will be used
NO. 3 STEEL An exceptionally clean P-20 AISI 4130 (modified) type cavity steel, pre-heat treated to 277-321 Bhn (28-35 HRC). It provides high hardness, good machinability, and exceptional polishability. It also provides excellent tool life, especially for zinc die cast dies.
REPLACEMENT UNITS IN ANY STEEL OR HARDNESS REQUIRED ARE AVAILABLE ON SPECIAL ORDER
