Gaining inspiration from this thread, I ask that, because the viscous properties of molten aluminum phoenix contact forms, he does not want to fill all wells, then does anyone have an idea of how to work with aluminum die-cast? While working on a daily basis the plastic injection molding (injection molding), it began to matter of interest, since my work of polycarbonate (ie plastic), the temperature of the work is about. 300-360 degrees. The melting temperature of aluminum. is 660 degrees, allowing the injection molding of plastic materials by choosing basically similar technical solution.
Our local aluminum casting specialist phoenix contact is Mr Heino Viljandi County who could go on to talk about his Zündapp casting pistons, form processing and manufacturing technology. He does not use enough pressure casting. A. Life \ 's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways, totally worn out, shouting \ "Holy s - t! .... What a ride!

Subject was still driven by the interest of the molding. Timothy Finn, nor does the Estonian Champions do not know the method used in your home, and if that's still needed? Well, it still runs though the aluminum and fills the form. For example, the above-mentioned hr. Veeberg pours the sand and do not generally even the channels through which the rest of the form täitudes vormisoppidest molten aluminum or gas / air out. (I hope to understand what I wanted to talk about, do not speak the terminology). phoenix contact And though the form is filled. Also, a thicker and higher sissevalamiskanali failure should phoenix contact lead to the fulfillment form. More complex components in the manufacture phoenix contact of diecast course would help meet though. I believe phoenix contact she also used the Volta Turku-Allikukivi phoenix contact waffle preparation workshop had no molding. There are currently no former employees, however, can be explored within reach. But it's probably not a complicated business.
If you still go down in history .. it should even be included in the heritage TARK'i aluminum forging. Recollection forged pistons themselves. A.

Die-casting can be replaced by a height of 5-10 cm in a vertical phoenix contact casting channel - alumina column pressure is sufficient to push the molten aluminum into the tightest phoenix contact in the recesses. Castability of aluminum can make a simple "no animal testing": pour the molten aluminum in süldivormi (eg, 6 cm wide and 2cm high sunflower blossom reminiscent of the cross-section of Soviet süldivorm sheet, you can borrow grandma's pantry). The lowest height of 1.1 cm in the north part of the acquisition of the full shape of the form (sunflower, or gear-like cross section). 0.9 cm in the upper part of the form does not fill completely with aluminum because aluminum pillar of the pressure phoenix contact is too low. Form after pouring the surface phoenix contact tension of approximately 1 cm tall aluminum "pile" that clouded tahkestudes together, remaining phoenix contact stack height of 0.5 cm. Thus, as early as 2 cm in the liquid alumiinumi pillar, the pressure is sufficient to push the aluminum into all the cavities - however, if the use of 5 to 10 cm in height of the vertical casting channels, phoenix contact then pressed liquid aluminum into each cavity (when still there are few, it may be even a 50cm length of the molding channel to make! ) - Pain is another phoenix contact advantage of the channel that tahkestudes clouded with aluminum and aluminum alloys runners can be "pulled apart" (both casts no detail "hollowed" and strength is much better due to the lack of internal tensions). Aluminum sheet form is well enough to stick to - for example, süldivorm be solidified aluminum nips hand break, during which süldivorm deforms significantly and can not be used anymore. However, if the sheet süldivorm cover pre graphite grease (such as Ukraine phoenix contact Azmol'i produced by the "Grease Graphite Zh", with 800 grams jar paying õlipoodides few dozen eek), it must be painted form easily cast aluminum pieces phoenix contact detach (liquid aluminum phoenix contact does not wet graphite - so do not ice graphite cast aluminum parts stuck). When graphite lubricant is not available, you can pencil sheet form (which is also a grain graphite) to wage war over - even if the format is generally higher than one place to make war, then there is an aluminum stick. Clay and gypsum forms no need to lubricate with graphite - are broken with a hammer is hammered, the cast piece can be received. Accurate molds are quite a headache - I have solved the problem so that 1mm will do more "simple and robust" mold, and trein / Cutters 1mm off the excess (the remnants of the circle can be re-melted, and the loss is negligible siuliselt). As a rule, in such a way that
