Pipe-die makers typically help customers calculate die and tip dimensions once they have an order for a die.

Pipe-die makers typically help customers calculate die and tip dimensions once they have an order for a die. But B&H Tool Co. in San Marcos, Calif., makes its in-house tooling calculators available for free on its website, www.bhtool.com. Users must register in order to use the calculators. One is the DDR/DRB Calculator for processors who want to optimize an existing tool for a new job. A processor enters four tool and product dimensions, and the program figures the drawdown ratios and draw-ratio balances. The other is the Tooling Calculator for processors considering a new die. A user enters product dimensions and resin-specific draw-ratio and balance data, and the program calculates die and tip dimensions. The calculator doesn’t store results but lets processors print them out to keep.
