Precision Casting Casting Casting Casting processing casting manufacturers

Turntable bearing seat is a kind of can accept the comprehensive load, construction of special large and extra large bearing seat, which has a compact structure, rotary sensitive, easy to maintain and so on.

Resin sand casting is collectively referred to in the shape of the core before the sand on the surface has been covered with a layer of solid resin film of sand, sand called sand, also known as shell (core) sand.It was first a thermosetting resin sand , By the German Cronin (CRONING) Dr. invented in 1944.

Surface roughness of the mold: The surface roughness of the mold surface plays a decisive role in the surface roughness of the resin sand casting, thus minimizing the surface roughness of the mold is an important measure to obtain high quality castings.

Resin sand casting The original sand and resin mixture is formed after the formation of resin sand, resin sand into the mold cavity, by heating or catalyst method to shape, after forming the core and then into the casting mold casting.

Resin sand casting With the surface roughness is small, high dimensional accuracy, good quality characteristics, resin sand production process requirements on the mold:

Compared with the clay sand, the appearance quality of the resin sand casting depends on the quality of the mold, so the resin sand has a higher quality requirement for the mold.When the mold technology makes it better to meet the needs of the resin sand molding, mainly in the following aspects :

Draft angle : Resin sand in the mold has been a certain degree of hardening strength, less concession, greater friction, if the use of percussion method from the mold, easy to damage the mold, while resin sand can repair poor, from the mold , If damaged, more difficult to repair.When using resin sand molding, should be based on actual production and product structure to increase the mold draft angle, can smoothly from the mold, the quality of the castings with the market appearance of the quality requirements of the product Resin sand casting in the quality of the advantages, will increasingly be valued, resin sand casting the production process, will also be rapid development and popularization.

Machining allowance: After hardening resin sand mold has good rigidity and high dimensional accuracy, and not easy to deformation, so the choice of process parameters, you can select a smaller machining allowance, thereby reducing the consumption of metal solutions and machining Cost, which can improve the dimensional accuracy of the casting.
