Metal Casting

Waxcasting, chill casting, die casting, aluminum extrusion, zinc casting, sintering, etc.

All dimensions and areas of post-processing control.

Waxcasting used where high precision requirements and smaller series. The tools created combs, which is applied to the stand in groups, which may then take a cast after it is coated with powdered glass and binder. In the past, made much of this work manually, but in our factories has aligned itself with its environmental requirements and mostly automated. By Ramo AB is certified according to ISO 14001, it is important for us to work only with suppliers who can handle these strong bond funds without prejudice to the environment and people. When the process is complete, dried honeycombs. Combs are placed in an oven and the wax runs off the cake. Remaining now is the mold that is capable of high tolerance requirements without finishing. Most types of castable materials are used. See our upcoming film presentation showing the manufacturing section. Comics from a few hundred to a few thousand may be feasible.

Chill casting is used for the manufacture of components exposed to special pressures or high demands on the printing density, among other things. In the case of complex structures, steel molds can be supplemented with “sand grains”, which offered further opportunities in terms of detailed design. The tolerances on the chill casting is very good. Comics for a couple of thousand is normal. Common materials are aluminum, etc.

Diecasting / extrusion aluminum / zinc die-casting is often portrayed in complex parts with high dimensional accuracy and surface finish. The actual die-casting tool is made of steel. Casting usually takes place in fully automated machines. Series up to hundreds of thousands of details.

Sintering is a process in which solid particles are assembled at high temperatures but below the melting point. Sintering can take place both between the particles, so that they are attached together, or within the particles, so that the pores are filled out. Sintering requires an individual to the material specific surface area decreases, and driven by the fact that a smaller area has a lower energy. Sintering can be increased by the material, or some of the material, partially melted, or by chemical reactions. Sintering used inter alia in the manufacture of materials by powder metallurgy. Most materials are Sintra. Comics from 5-10 thousand.

Other molding technology can be ensured so that as plaster casting. Ask us and we leave the best proposal.
