DZynSource for Molds software version 3.0.0 has just been released, with several enhancements that make it more user friendly.  DZynSource for Molds is an engineering, calculation and reference resource software for mold designers, tooling engineers, molders, mold and toolmakers, machinists and anyone involved in any engineering, production planning or machining aspect of mold design, moldmaking or molding. It saves users from spending too much time looking up and crunching equations.

DZynSource for Molds automates most of the calculations that commonly arise during the design, checking, machining, running and troubleshooting of molds. Users can choose the calculation they’d like to perform, enter the known data and press “Calculate.” Answers are provided with diagrams to avoid interpreting complicated formulas or equations.

Material properties are available for mouse click selection when entering material property data.

There are eight basic direct current electrical calculations and many fluid calculations, including: bubbler sizing, continuity equation, general and special case annular passage for equivalent hydraulic diameter, hydraulic and pneumatic cylinder calculations, pressure losses and Reynolds Number.

There is also a basic Galvanic table and a hot runner checklist of common mistakes that can be avoided when ordering hot runner systems. The software features gate and runner size calculators for molds that are designed with cold runners. The mechanical properties of 31 common moldmaking metals, including steels and aluminum and beryllium copper alloys are included in a separate module.

Newly added molding calculations include chiller sizing, clamp force requirements, the Ballman and Shusman cooling time estimator, the minimum mold open time, mold fill time, the plastic processing volume in pounds or kilograms per hour and tie bar stretch calculators.

Also related to molding are the production calculators, such as the number of cavities required in a new mold, the quantity of parts that can be molded in a given amount of time, the time it takes to mold a certain quantity of parts and the previously mentioned pounds/hour of material being processed.

Machining calculators include effective cutting diameter, feed rate/feed per tooth, a converter between inches/minute and inches/revolution, surface feet/minute, surface roughness calculator based on feed direction and/or step over rate and a module to calculate the sine plate angle to be used for three-sided cutters.

Sizes, properties and torque values for inch and metric screws, and tap drill sizes for N.P.T and B.S.P.T. pipe taps are available.

The Strength of Materials calculations are mold plate deformation, beam deflection and stresses (think mechanical components like leader pins, cores, screws and so forth), hoop stress and cavity expansion and long column buckling calculations, which have come in handy when using small ejector pins under the gate. Elastic stress and strain, moment of inertia, section modulus and radius of gyration for 10 common geometric shapes are also part of the package.

The thermal expansion module includes coefficients for the 31 common moldmaking metals. Users can calculate the amount of expansion, the initial size to grow to a given length or the final size after expansion. There are surface finish charts, a vent width calculator and a vent depth table, tooling ball, roll dimension, chord, sine plate, (degree, minute, second to decimal degree and vice versa) and right angle trigonometry modules as well.
