There is a risk of void formation and reduced welding quality.

Pores and shrinkage cavities are also excluded.

Namely, the production of thick-walled plastic bodies has the problem of cavity formation.

In the integral casting of the tubular heating element the problem of spontaneous bubble formation arises.

Turbulences form, which lead to cavitation and to density variations in the pipe.

Effects such as alpha-case layer or shrink hole formation are reliably avoided.

At the same time, these design options also reduce cavity formation.

When pourability is poor, the mold can fill irregularly and cause the formation of holes and blowholes.

There is a tendency toward carbide precipitation, intercrystalline corrosion, blowhole formation, inclusions and other structural flaws in the material.

The high Si content leads to a very good castability and to reduction of the cavitation.

With the test bars chosen (plates with bosses, without risers), cupola and electric-furnace irons can be distinguished by the shape and extent of shrinkage defects.

A certain detrimental effect of steel on tendency to shrinkage was found in the case of cupola cast iron.

The quality and above all the homogeneity of the soldered connections attainable are extraordinarily good, compared with the prior art methods, which can be ascribed to the fact that the method according to the invention avoids creating a deposit of soldering paste in the conventional sense, with its associated disadvantages such as bubble formation, oxidation of the soldering paste, fine granulation and the like.

For example, they must be sufficiently flowable at as low a pressure as possible so as to fill the mold without forming shrink holes, and nevertheless perform their protective function on the finished semiconductor device.

The tools cast on zinc basis have the disadvantage that zinc has a tendency to bubble formation.

However, this process is burdened by the considerable disadvantage that it is possible only to manufacture sheets having a relatively minor thickness of a few millimeters since the rolling of sheets having larger thicknesses of above 5 mm presents considerable difficulties due to the danger of bubble formation, i.e. air inclusions.

For example, work hardened materials could not be used, which are considerably more cost-effective and which exclude from the start the formation of bubbles and structural changes.

As the hole aspect ratios continue to increase (i.e., the ratio between depth and diameter), this contact metallizing can no longer be done by deposition of the usual layer construction (such as Ti/TiN/W), since current sputtering methods do not allow conformal deposition for Ti/TiN and thus always leave behind a negative blank angle, which even with conformal tungsten CVD leads to shrink hole formation.

During such a deposition, a so-called “shrink hole formation” arises since the trench cannot be completely filled on account of the increased deposition at the upper edge of the trench.

When the foam mass is loaded with the bonding agent at the time when the main component is mixed in, namely the pulverulent mineral solid material, there is the danger of void formation.

On covering the wire a spiral bead forms as a result of the pressing of the ploughed edge along the insertion line and this can contribute to air inclusion formation in the joint area between the sleeve and the pipe.

A particularly important role in this is played by the proper arrangement of the casting models in the dead casting mold, since a defective arrangement can result in porosity and shrinkage cavitation (information document "The exact-fitting dental cast" issued by Heraeus Edelmetalle GmbH, Hanau).

That process has the disadvantage of producing two separate layers, so that it is not possible to reliably prevent uneven deposition with the development of bubbles and/or fluctuations in stoichiometry.
