DZynSource for Molds software, version 3.0.0, has just been released. The new version includes many enhancements, making it easier to use than ever before.

DZynSource for Molds is 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, mold making, 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. Choose the calculation you'd like to perform, enter the known data, and then press "Calculate". The answers are displayed in a flash. There are diagrams to make it simple, no need to interpret complicated formulas or equations.

This new version of DZynSource for Molds has many new features and has been made more user friendly. Material properties are available for mouse click selection when entering material property data.

There are 8 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 a basic Galvanic table and a hot runner checklist of common mistakes that can be avoided when ordering hot runner systems. There are also gate and runner size calculators for molds that are designed with cold runners. The mechanical properties of 31 common mold making metals, including steels, and aluminum and beryllium copper alloys are included in a separate module.

The 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 per hour of material being processed.

Machining calculators include effective cutting diameter, feed rate / feed per tooth, a converter between inches per minute and inches per revolution, surface feet per 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.

there are also 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.

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, the long column buckling calculations 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 mold-making metals.
You 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.
