Aluminum foundry molds

The permanent mold casting

favorable mechanical properties, called for greater strength and higher material density, asked the casting process.

Advantages:

Due to the rapid dissipation of heat produced in permanent mold casting a fine-grained, dense structure with good mechanical properties. The castings have high dimensional accuracy and surface quality, and must be mechanically finished only to a small extent. The method is also very productive.

Description:

The permanent mold casting is one of the precise casting. Poured is falling in metallic permanent forms which are designed for the removal of the finished casting two or more parts. Cavities and undercuts are generated by cores of metal. Due to the high thermal conductivity of the mold, the melt solidifies very quickly and there is a fine-grained structure.

Dimensional stability:

It is strongly dependent on the mold material (usually steel or cast iron) from the casting metal and the casting geometry.After an average of about 20000-30000 watering procedures, the mold must be reworked.

Our alloys:

GK Al Si 12 (Cu), GK Al Si 12,

Mechanical processing:

After casting, the aluminum parts are processed in our house. It starts with the saws, goes on cleaning for drilling and tapping if necessary to Blank roles.

In processes that we do not do yourself, are we reliable partner.

Logistics:

Thanks to our own fleet, you will quickly and reliably supplied with the manufactured goods.

We design and produce aluminium diecasting parts, including machining, painting, assembly, etc. Also distribution through Europe.

KONMAK IND. INC has been producing marble machine productions on a large scale since 1980 and has thus acquired an extensive expertise in mechanical productions. Having based ourselves on the features demanded by large companies, we have created innovative, user-friendly applications that are now available to small and medium-size companies.



Our keen knowledge of the marble machine industry has helped us develop solutions that answer the needs of today’s clients. These solutions allow you to increase productivity, reduce operating costs and increase customer satisfaction. All of our marble machines are produced on CNC controlled workbenches which are designed by KONMAK’s R&D department. The machines are tested in KONMER-the brother company of KONMAK-to ensure the high quality. Also, we produce assembly and layout plan of the water clarification tanks which marble producers need.



We also provide concrete mixers which fit the European standards of abrasion resistance. Our concrete mixers are user-friendly and efficient. Besides, we also export cable machines to lots of countries such as Iran, Syria, Egypt, Sudan and Jordan.



Our products also include sail masts which are aesthetically pleasing and corrosion resistant. KONMAK is a major supplier of underground and pressure vessels, textile, food and chemistry sectors. Utilizing the latest manufacturing technology standard of ISO 9001-2000 EQA Quality Management System, KONMAK participates lots of national and international trading exhibitions.



Further to our information, please take a few minutes to visit our website: www.konmak.com. See how KONMAK’s marble machines can optimize your business. I invite you to contact us today so that we can discuss in details how we can help you.



Thank you for the interest you have shown in KONMAK!

Manufacturing at KOVOHUTĚ HOLDING DT, a joint-stock company, division Kovohutě Čelákovice, consists of three technological operations which proceed in order. There is also a series of preliminary and subsidiary operations involved. At the beginning, there is raw material input and the process ends with an output of semi-products ready for additional processing (semi-finished products). The basic technological operations are melting and casting, extrusion, and drawing.

Melting and casting is when an alloy of specified chemical composition is prepared as rolled semi-product. Electric induction furnaces are used for melting, and some special alloys are manufactured in a gas-fired crucible. Samples for material analysis are taken before actual casting. After cooling the castings are divided into various lengths according to the pressing shop's requirements.

Extrusion is a very demanding and expensive process and needs perfect equipment, high-quality tools, and accuracy within determined parameters. Extrusion is carried out by hydraulic extrusion presses from ingots, which are heated in electric induction furnaces at temperature ranging from 700 to 1000 degrees centigrade. Bars, tubes, wires, and sections in straight lengths or coils can be extruded. Easily oxidable metals, for example copper, are extruded into water. Dimensions, surface quality, and flatness are checked.

Cold drawing is a process in which raw material is drawn through a die at normal temperature. A die or punch is a tool which is made from steel, sintered carbide, or from other materials. Its dimensions and geometry and surfaces have to be very precise. The surfaces must be absolutely smooth in order not to mar the semi-product. The friction when drawing should be minimal.

In the drawing process, material properties change. The strength is higher, but the quality of the drawn product is reduced. The structure is adjusted and becomes finer. The drawing process is limited to a certain extent. Exceeding limits could damage the structure of most metals. Cracking can occur as well as tearing. Only a few metals are exceptions (e.g., pure copper). Its hardness is limited, but even then it is possible to draw it without danger of damage.

Drawing can be combined with rolling for a more regular shape. For this operation rolling machines are used. They can be pilger rolling machines or ordinary ones producing flat or grooved rolls. Drawing conveyor lines are often used for this purpose. They link several production steps one after the other. Conveyor lines save expense and lessen the dangers of handling material; they also increase labor productivity.
