https://www.facebook.com/WynnDanzurMarketing
The purpose of website has always been to serve your Metal Casting needs. Today as yesterday we are both proud and thankful for everyone's support all of these years. ______________________________________
______________________________________ The 2012 Wynndanzur.com website will help you in the purchasing of American Made Aluminum Castings, Iron Castings, Steel Castings, Iron Castings, Die Castings, Investment Castings, Powdered Metal Castings, and more.
More than ever before, the purchasing of American Made is more than just being Patriotic, it is very Profitable, and it is very Safe! To learn more about "Why to American Made," please take a minute to PRESS the Blue link below: BREAKING NEWS: Brazil to Slap Quality Control on China Goods; USA may follow soon.See all the Story inside this Buy American link !!
********************* Here in the USA, we build all of these type of cast components with the following Processes; Sand Casting Process, Permanent Mold Process, Investment Casting Process, Die Casting Process, Hunter Automated Equipment Process, Squeezer Casting Process, and more.
*********************
This website will explain these Casting Processes in such a way that everybody will enjoy and learn.

We are very sorry! Recently many have been sending us e-mails only to get them bounced back. Reason for this is work was done on the website, and in that process the e-mail address was corrupted. The e-mail address is now fixed. We sincerely thank all of you loyal readers and customers whom called us about this problem.
Come on in side and let's get to know each other ..... _____________________________________________________________________________________

1. The Basic Components, found in Molds / Dies. see text below diagram ___________
The parts of a Mold / Die are: Pouring cup - the molten metal is poured in here. It has a funnel shape to ease pouring accuracy problems. Runner / sprue - a sprue carries metal from the pouring cup to the runners. The runners distribute metal to the part. Gate - a transition from the runner to the cavity of the part Riser - a thermal mass where excess metal will remain in a liquid state while the part cools. As the cooling part shrinks, the molten metal in the riser will feed or fill in the shrinkage. Risers can also be used to collect impurities that rise in molten metal. Mold cavity - this is the final shape of the part, the pattern would be found here prior to molten material.Vent - a narrow escape passage for gases that would otherwise be trapped in the mold. Parting line - a line of separation that allows the mold (made in two pieces) to be put together to make a full cavity. Note that this line does not have to be a straight line, and is often staggered to make the mold making easier. Cope - the upper part of a casting mold Drag - the lower part of a casting mold
There are important Casting Concepts about patterns,
2. What Is a Core ?
Cores are typically used for more complex shapes. Cores allow features that could not be easily formed into a sand core. Cores are made with techniques similar to those for making sand molds.The cores may need structural support in the mold - these metal supports are called chaplets. The cores are added when the cavity are made, and they act as part of the mold during casting, but they are rigid enough to allow internal features on parts. Cores can be made easily in automated settings.
3. How is a pattern or die poured off ?
4. How does Investment Casting work ?
5. What is Lost Foam Casting ? Is it different than Investment Casting (lost wax ) ?
Lost foam, is similar to Investment or Lost wax, in that the medium, or pattern device, is Expendable, they melt or evaporate away, leaving the cast part. They both have advantages, for the type of function they were designed. One Process's advantage, could be the other Process's weak area. These points are brought up in the text portion of Education Section.
6. Shell Core Molding
7. The " V-Process " -- vacuum sealed molding, how it Works.
The V- Process works like this: A thin plastic film is heated and place it over a pattern. A vacuum tightly draws the film around the pattern which is then surrounded by a flask. Next, the flask is filled with dry, un-bonded, extremely fine sand and vibrated, so that the sand tightly packs the pattern. A second sheet of film is placed on the flask, a vacuum draws out the remaining air, and the completed mold is then stripped from the pattern. Each half of the mold is made in a like fashion. Aluminum or the Alloy of choice, is then poured directly from the furnace into the closed halves. As long as the mold is held under vacuum, it retains its shape. After the mold cools, the vacuum is released and the sand and completed casting fall free. The "V " Process is simple in concept but adds a whole new dimension to the Casting Industry. The plastic film, melts, and diffues into the sand; the sand is left to cool and is ready to use again. Examples of usage would be: the medical equipment, instrumentation, electronics, machine tool , aircraft machine tools, musical drivers ( speakers ), church bells, automotive testing and repair equipment, to mention just a very few applications. Follow the numbered steps listed below, to gain a better understanding of this innovative process.
