Casting Process

CENTRIFUGAL CASTING PROCESS

Centrifugal Casting Process, sometimes referred to as Rotocasting, made by pouring liquid Bronze from ladle into horizontal spinning die, a rotating mold. Rotation of the mold causes the centrifugal force that will push and compress the liquid into the mold wall for some time until the liquid freezes. Centrifugal Casting process excellence is a dense grain structure, smooth, and high tensile strength and tenacity.

CONTINUOUS CASTING PROCESS

Continuous Casting  method is done by pouring liquid Bronze from a furnace into necked  crucible ( Holding furnace ) which has a graphite mold. Fluids will be frozen and pulled out by a roller continuously. The strength of Continuous casting  process in the increased of physical and mechanical properties compared to the sand casting process. In addition, the products will not only be free of inclusion defects and the size will be precised, but also create various kinds of forms both solid or hollow standard.

SAND CASTING PROCESS

Sand Casting, is the most common casting process that widely used, the process is carried out by filling the liquid Bronze into the ladle and then poured it into sand mold which is formed according to  the pattern of the product. After the Bronze is cold, the mold will be dismantled and the product will be removed. The strength of sand casting process the possibility to make range of component from small to  small  to large, both simple and  and complicated shape.

Quality Improvements and Controls

Accurate and strict quality control is one of the integral processed of ALPHA BRONZE products. Any possibility of composition, dimension, hardness and moisture, and inspected and tested to ensure the best quality of Bronze Products.

ALPHA BRONZE

Alpha Bronze is a bronze product manufactured by PT Alpha Austenite, a manufacturing company that has been in-revitalizaton by its parent company, namely PT TIRA AUSTENITE Tbk, and has made some improvements on every aspect of its business to ensure only high quality products are supplied.

ALPHA BRONZE is produced from ingot materials with a grade that is based on international standars, which was selected and carefully examined through the analysis and its metallurgical properties.

Several casting process options are is Continuous  Casting, Centrifugal Casting, and for some cases are processed by Sand Casting for special sizes and shapes to meet various customer needs.
