Atra Co., equipped with design, manufacture and quality control components, declares its readiness for manufacturing molding patterns for almost all kind of mechanical parts.
The main activities of the Atra Company’s Modeling Group are as follows:
Manufacturing steps schematic view for a casting part (centrifugal pump impeller)
A notable point in designing casting models for molding is that the model should be made in such a way as to match the casting conditions. Since Atra Company has a vast experience in producing parts for casting, it is well aware of the requirements and limitations of molding, and so the models made by this company can easily be produced in factories and workshops that make molding manual and semi-automatic.

Moulding Core and Cavities are used in injection moulding producing parts by injecting molten material into a mould. This kind of moulding can be performed with very different materials like aluminum and magnesium alloys (die casting), thermoplastics, glasses and elastomers. Atra Company, based on the experience and knowledge of its experts, utilizes world class machines and specialized softwares in the field of design and reverse engineering, manufactures moulding core and cavities as follows;
The steps in the Atra mold manufacturing unit are as follows:
Die Casting Mold Cavity; for different kind of materials and alloys, like Aluminum and Magnesium alloys. This kind of cavities have a wide range of applications in different industries. Some of die casting applications are car components (like seatbelt parts, headlight parts, engine crankcase and torque converter parts), shell housings (like transmission case housing, electric motor housing) and heat exchanger parts (like inline heat exchangers and boiler components).
