different kind of forging products incl. machining

Precision forged parts are forged parts where very narrow tolerance can be achieved by following the forging process permanently. Our processes enable forging with the +/- 0.1mm tolerance. We are specialized in the production of precision forged parts weighing between 0.001kg and 1kg made of different material. The advantage of precision forged parts is that they can be used mostly in different compounds and without additional mechanical machining. Hot die drop forging is the method in our company – sticks are heated and inserted into the appropriate forging tool.After the forging process, we trim and pierce the semi-finished products to meet many shapes and other requirements. We shape stainless, alloy and carbon steels. In most cases, more complex and larger forgings are further machined.Due to the specificity of precision forgings, we provide the minimum necessary additional machining and thus reduce the machining times.

Hollow forging offers a revolutionary approach to product creation by incorporating hollow internal structures. This innovative technique leads to substantial material savings, with reductions ranging from 20% to 70% compared to traditional forging methods. The extent of savings depends on factors such as the product's shape and the design intricacies of the hollow structure.

We provide complete R&R (reworking and refurbishment) services for forging pieces based on your drawings, taking into careful consideration your specific requirements and the forging principles that must be adhered to. Our expertise ensures that your needs are met with precision and attention to detail. Furthermore, we offer guidance in selecting the appropriate type of material based on your product specifications and requirements, ensuring optimal performance and quality.

Our expertise lies in the meticulous development of tooling for both steel and aluminum forgings, ensuring that the need for post-processing of the pieces is minimized. By perfecting the tooling process, we strive to deliver forgings of exceptional quality with minimal additional work required. Moreover, we offer valuable recommendations to our clients regarding potential alterations to the forging piece aimed at reducing costs without compromising on quality. Our goal is to optimize both the piece and the die to enhance efficiency and cost-effectiveness.

At Extra Forge d.o.o., we also specialize in the closed die forging of aluminum. We can forge products from any aluminum alloy, with weights ranging from 0.05 to 6 kg. Our company prides itself on having professional associates who were among the first in the region to forge aluminum products, a process distinct from steel forging. Our advanced technological processes for die forging aluminum semi-finished products allow us to achieve an accuracy of ± 0.2 mm, ensuring precision and quality in our forgings.

Extra Forge d.o.o. is a leading production and service company specializing in closed die forging of various types of steel, including stainless steel, high and low alloy steel, and carbon steel. Our expertise lies in the hot forging of steel semi-finished products ranging from 0.1 kg to 8 kg. This process enhances the strength and toughness of the products compared to other manufacturing methods. The advanced technological processes at Extra Forge d.o.o. enable us to achieve forging precision up to ± 0.2 mm, ensuring high-quality and reliable products.

With knowledge gained in past years we can provide you with a complete solution – from the idea to the final product. We cooperate with customers from the beginning, from the idea and this is how we contribute to faster solutions in the field of implementation of forged parts into the final system.Modern software and highly skilled employees are keys for the good-quality, fast and expert construction of complete tools and compounds.To design and program machines we use Siemens NX and Visi Vero software, which enable us to read and write data in several possible formsNX files, Solid Works files, IGES, PARASOLID, STEP, SXF, DWGBy using conversion modules, we can also open and saveCATIA, Pro / E, Inventor and STLTo achieve the shortest possible time from development to final products, we use modern software for simulating forging. We have a QForm product in use, a synonym for forging simulations.

Only high-quality steel is appropriate for high-quality products which are mostly assembled in the cars of our customers. By using hot forging process, we shape different types of carbon steel, all types of alloy steel and most of the time stainless steel.The Hot forging process and thus the transformation of steels has a number of specific points in its process. We have directed the development of forging into forging stainless steels, as these steels are increasingly present in automotive engines as well as in other segments of the use of forged parts. The advantage of stainless steels is that they are corrosion-resistant, and do not require additional surface protection. Through the hot forging process, we are able to transform both ferritic, martensitic and austenitic stainless steels.

The advantage of the Marovt company is that forged parts are machined in our own forge. This is why we are able to ensure forged parts with characteristics defined together. The machining of forged parts is mostly automated; therefore, the human factor is decreased and permanently the same technological process can assure all parts to be machined in the same way and being controlled and tested according to the same procedures.The machining of forged parts is carried out on technologically advanced 3 and 4-axe machines. Our machining centres have the possibility of using up to 40 changeable cutting tools. The tool can be up to 300 mm long and up to 10 kg heavy.The machining center spindle can rotate up to 20,000 rpm. Changing the cutting tool at our centers only takes 1.7 s, which greatly shortens the machining time. All our machining centers have a pallet system that eliminates the time of mounting the forging parts into the clamping device.

Utilizing state-of-the-art CNC 3 and 4-axis milling and turning machines, we excel in executing precise post-forging operations as per provided drawings and specifications. Whether it's milling or turning, our advanced machinery ensures accuracy and efficiency in every process.
