Aluminium high pressure die casting

Aluminum High pressure die casting is a manufacturing process in which molten metal (aluminum) is injected with a die casting machine under force using considerable pressure into a steel mold or die to form products. Because of the excellent dimensional accuracy and the smooth surfaces, most high pressure die castings require no machining except the removal of flash around the edge and possible drilling and tapping holes. High pressure die casting production is fast and inexpensive relative to other casting processes.

Figure 5: Schematic view of high pressure die casting machine This equipment consists of two vertical platens on which bolsters are located which hold the die halves. One platen is fixed and the other can move so that the die can be opened and closed. A measured amount of metal is poured into the shot sleeve and then introduced into the mould cavity using a hydraulically-driven piston. Once the metal has solidified, the die is opened and the casting removed. In this process, special precautions must be taken to avoid too many gas inclusions which cause blistering during subsequent heat-treatment or welding of the casting product. Both the machine and its dies are very expensive, and for this reason, pressure die casting is economical only for high-volume production. From the earliest application of die casting in manufacturing, the process has evolved from the original method of low-pressure injection into the development of high pressure die castings. The methods employed for creating high pressure die castings result in components that come out of the die in close to finished condition, with superior finishes and shape.

While high pressure die castings can be slightly more expensive, because of the excellent results and elimination of the need for secondary machining, high pressure die casting can be an economical choice for high volume production applications. The experts at Cascade Die Casting Group are ready to assist you in developing a customized approach to your component needs. We have the equipment, know how, and capability to apply the benefits of the high pressure die castings process to the parts you need for your application.

Plastic Mold Making business

I received an interesting e-mail yesterday from someone inquiring about making plastic molds for building planters with faces on them.

I’m going to just copy it and paste it here. So you can read it to.

Del,

I found an article http://www.abceo.com/ and I’d like to try to make these planters but I don’t know how to make the plastic mold. Can you assist?? I work for an agency that works with developmental disabled individuals and we started an art gallery and would like to make some of these planters to sell.

Thanks,

S Belle

Hello S Belle:

Thanks for visiting my site.

I have been thinking about your request for info on making plastic molds for heads to use as planters.

I don’t know where you could buy the molds but can guarantee that they would be expensive and require some expertise to use.

If I was going to try this I would go to garage sales and hobby stores looking for “heads” to use as the basis for my mold.
Plastic Halloween masks make nice cheap plastic molds. Look for ones without any undercuts and that are fairly rigid.
Make up a sand bed with clean moist sand _ if you can pick up a handful and squeeze it, it should stay together.

Cover the eye, nose, and any other holes in the mask. Before you place the mask in the sand bed – coat it with some 10w engine oil. Get the cheapest stuff you can. Don’t put too much on or it will make pits in the surface.
Pack the sand around and under the mask to make sure it holds its shape.
Mix some hypertufa and carefully pack it into the mask.

You will have to wait patiently for a couple of days for the hypertufa to cure. You should be sure that it is kept damp during the curing time.
Once it has cured remove it from the mold and use it to form the front of your Pot-Head.

Maybe you could get some sort of Styrofoam container that you could cut a piece out of and fill the gap with your face casting. Then just use the hypertufa as a glue and filler to cover the container and to holes the casting into place.

I can see it now – you will get a bunch of Richard Nixon masks…….
I hope this gives you some ideas to work with and would like some pictures and commentary if you follow through. (for me to post on my site)

I would like to use this reply as an article on my site (if I get ambitious) and would change your name if it is OK with you? I can leave your name if you like, but either way I will remove the references to .com etc.

Good luck and best wishes’,

Del

Hello again Del,
Thanks for responding!! I’m thinking about buying two head planters and yes they are expensive but I thought I would bite the bullet and then use them for molds. They are, I think concrete planters, and so my next question is how do I use them to make a mold. The answer to your question about posting my questions on your site is fine as long as you change my name and don’t use my organizations information.

Thanks,

S Bell

Hello S Belle:
On my site I have an article about making rubber molds. I would advise against trying it unless you are real adventurous. It is a big job you have to make the actual rubber mold (this is probably the easy part), then make another “case” that comes apart to hold the mold while you pour the concrete. This is generally fiberglass and unless you or someone you know has done it before it is quite a project.

Even if you have purchased a plastic mold you will discover you need a vibrating table in order to make aluminum die casting with no air pockets and it will take a few practice runs before you are able to produce anything that is saleable.
My feeling is if you get some masks and use hypertufa, you don’t need any special skills, you can pack the ‘tufa by hand and will be making nice looking planters in a short period of time. You could make a few ‘faces’ and the go ahead and incorporate them onto your hypertufa planters. One of the nice things about it is that you can ‘glue’ it together.

One other thing is the ‘tufa is very light so you don’t have to have a lot of help to set them up for sale. It is also generally ok to have some flaws in tufa as it adds to the rustic look. Being done by hand means that you will not have a lot of identical planters for sale – similar but not the same. You will find that after you become comfortable with the stuff you will be making more and more articles of your own design.
You may want to get this information – it has helped a lot of people get a feel for what is involved in this hobby.
I hope this helps some, and thanks for the permission!

Del

I hope this is useful to anyone who’s considering making their own molds. If you have any questions please ask and I will try to answer them.

Magnesium Die Casting

Magnesium Die Casting

CNM Magnesium  is a die casting china company that produce and supply a complete range of die casting like aluminum die casting, zinc die casting, magnesium die casting and sand casting alloys together with the associated hardeners, fluxes and welding rods. Service partnerships with our customers include extensive technical support in the melting and casting of our product range. In addition, our development teams work closely with end users to ensure component designs maximise the potential benefits from using magnesium alloys.

Magnesium Die Casting Alloys

CNM Magnesium die casting began supplying magnesium casting alloys in the 1930’s and have since developed the most extensive range of magnesium alloy systems leading to improvements in mechanical properties both at ambient and high temperatures of up to 300°C. For high performance sand casting alloys, three main alloy systems are used.

For general purpose applications, the Mg-Zn-Rare Earth alloys Elektron ® RZ5 (ZE41) and Elektron ® ZRE1 (EZ33) are easy to use and provide good tensile properties up to 150oC (302oF). The alloys are widely used for motorsport and aerospace gearbox casings, Elektron ® ZRE1(EZ33) is used in aero engine components where improved creep resistance is required.

The new CNM Die Casting china company  has been developed to offer improved properties and superior corrosion resistance whilst maintaining the processing advantages of the Mg-Zn-Rare Earth alloys. The alloy is used in military and motorsport applications where these properties are at a premium. Elektron 21 has achieved Aerospace Material Specification AMS 4429 and is the first magnesium alloy ever to achieve full MMPDS (MIL-HNDBK-V) design handbook entry, including statistical A & B values and elevated temperature information. For applications operating up to 200oC (392oF), engineers can now have extra confidence when designing strong, lightweight components with CNM 21.

Magnesium die Casting Alloys

For very high temperature applications, up to 300oC (572oF), the yttrium containing alloys are usually preferred. These alloys were developed for improved mechanical properties at elevated temperatures. Yttrium containing alloys have good creep properties and also have excellent corrosion resistance compared to other high performance magnesium alloys. CNM ® WE43 is used primarily for aerospace applications and CNM ® WE54 for high performance automotive applications.

These alloys have largely replaced other high temperature alloys including the silver containing alloys, CNM ® MSR-B, CNM ® QE22 and CNM ® EQ21 for new applications.

Magnesium die Casting Alloys

Magnesium die casting alloys are being increasingly used in commercial automotive and ICT applications due to their excellent castability, good strength to weight ratio and excellent corrosion resistance. CNM ® AZ91D, CNM ® AM50 and CNM ® AM60 are produced and supplied to diecasting foundries worldwide. The supply of alloys can be supported with CNM’s Recycling Service, capable of managing high and low grade magnesium process arisings.
