Build better molds the first time

Optimize mold cooling

Plan for thermal expansion and contraction

Specify chillers, cylinders, valves, and pumps

Size mold plates appropriately

Specify correct components and fasteners

Troubleshoot molds and molding processes

Over-design is expensive

Under-design can be disastrous

with heatersand hotrunnersystems.

The equivalent diameter ofan irregular shapedpassage is not the same asa diameter of equal area.

The equivalent diameter of an annularchannel is much smaller than mostpeople think it is.

You can calculatethe forward force,the return force,and number of

gallons perminute ofhydraulic fluidneeded, all whiletalking to your

customer on thephone.


9/91

Calculate the correct piston boresize for your application.

Calculate the forward force

Calculate the return force

Calculate the SCFM of airrequired for operation.

Get the answers as fast as youcan type.


10/91

You cancalculate thepressure lossesin your mold, orhoses.

You can alsocalculate the factthat there is verylittle pressurelost through

small fittings, inmany cases.

Make sure that your cooling is maximized by achieving a flow rate that indicates a ReynoldsNumber over 4000.

Make sure that your hydraulic lines dont exceed a Reynolds Number of 2000. See how anti-freeze hampers your mold cooling!

The closer twometals are in thetable, the lesslikely they are tocorrode whenplaced together in

an electrolyte.

Heres a list ofquestions thatyou can use as achecklist whenchecking hotrunnerdrawings. Thelist is based onexperience .

The checklist is

in a limitedword processor,so you can addyour own itemsto the list.

Calculates therequiredcolorant interms of let-down ratio, or

percentage.Choosepounds orkilograms.

This allows you to calculate the pause time for the molding machine to wait forthe molded part to fall from the highest cavity to the bottom of the mold.

Calculate steelsizes, knowingplastic size andshrink rate, orcalculate plastic

size, knowingsteel size andshrink rate.

Includes a table

of typical shrinkrates for somecommon plasticmaterials.

Calculate the Amount of Material to be Processed PerHour is found here, as well as in the molding calculationssection.

Calculateyourproductioncapacityquickly and

easily!

Sometimes you knowyour production runin hours, and want toconvert it to a larger

unit of time. Doneand done.

Calculate runnersizes based on partwall thickness.

Calculate the size ofa feeder runnerbased on the sizeand number of

branch runners itwill be feeding.

The strength of materials section issort of the heart of the DZynSourceMold Engineering Software, and thereason that I originally startedwriting this code.

There are many options from thisselection set, and many more choiceswithin each section.

to the proper textboxes.

2 differentloadingscenarios,2 differentsupportscenarios.

Good forcalculating thedistortion fromgating on a

core, or thecollapse of acap or closure,among otherthings.

The answers for this section appear in a separate dialog box.

Here again, the modulus of elasticity can be chosen from a list, or enteredmanually. The moment of inertia is transferred from the worksheet shown

earlier.

Moment of inertia,section modulus, radiusof gyration, and area areall used in thecalculations of strength ofmaterials.

Just enter your knowndimension for one of theten standard shapes toget the values you need.

Most values are sent tothe appropriate textboxes automatically.


68/91

Have you everseen a mold withA side actionfail to keep theslides fully closedduring injection?

You dont have toexperience thisagain if you sizethe plate correctlythe first time.

Both throughpocket and blindpocket options.

You can chooseto calculate theexpansion andthe final size.

You can alsocalculate what tomake the initialsize in order fora part to grow to

the correct sizeafter a change intemperature.

You can calculate thesize for measuringthreads with thethree wire

measurementtechnique.

You can calculate thelargest, smallest, andbest wire size to usebased on the threadsper inch, or the threadpitch.


77/91

You can select N.P.T. threads,or B.S.P.T threads. Once youclick on the thread size, you arepresented with the tap drill sizefor that thread. You will get 2answers, one for the drill size ifusing a pipe reamer too, or alarger size if no pipe reamerwill be used.

Using the image at the right to decide, choose the 3 options tocalculate the value that you need to know. You can calculate thechord, the radius, or the height of the segment, if you know theother two values.


81/91

Most calculatorsinclude a decimaldegree to degree,minute, second,calculator.

We included one hereso that you haveanother source forwhen your calculatorbatteries lose their

charge.


82/91

Choose any twovalues that youknow, from thelist, and pressCalculate to get theother 3 values.

The 90 corner isconstant.

You can enter your

angle in decimalsdegrees ordegrees, minutes,seconds.


83/91

Using a roll, dowel pin, or gage pin to measure angles is very common in moldand tool making. There are two choices available to represent the orientation ofthe angle. Just enter the angle, the height to the theoretical sharp corner, and thepin or roll diameter, press calculate, and the height over the roll is calculated for

you. No more using charts and cheat sheets.

Of course, its still up toyou to put the vents inthe right spot. But thiscalculator tells you theminimum vent widthyou need to preventburning of the plasticmaterial.

Its usually better to havemore vents, as long as

the structural integrity ofthe core and cavity arenot compromised.
