Underwater pelletizing
ECON specializes in the development, production of innovative solutions for underwater pelletizing technologies. Since its establishment in 1999 ECON has secured numerous patents. The company's commitment to continuous improvement and technical development make it a recognized innovation leader for pelletizing systems.
Global producers of virgin resins, compounders, masterbatch manufacturers, and recycling companies all value the quality and efficiency of ECON equipment.
The uniqueness of the ECON underwater pelletizing is the patented thermal insulation technology. The thermally insulated die is fixed to the heated die carrier body. The innovative ECON technology allows granulation of all thermoplastics, including those that are difficult or practically impossible to granulate with other technologies, such as materials with strict temperature requirements, materials with high filler content and materials with high melt flow index. The CECONID® die plate material, which is highly wear-resistant for a long service life, allows this technology to be widely used - particularly for processing glass fiber-reinforced polymer materials. The throughput of underwater pelletizing systems is from 1 up to 15 000 kg/h.
Patented Thermal Insulation Technology provides the following advantages:
• no „freezing“ of die holes - constant high pellet quality
• thermally insulated die plate attached to heated die carrier body
- constant temperature trough the carrier body
- no overheating of the melt
• reduced energy demand - increased profitability
- less heat transfer to the process water
- less cooling energy required
- less extrusion pressure
- less heating energy required
- lowers your operating costs – increases your bottom line profit

Mixers and polymer mixing systems
Polymer mixers are additional equipment that speeds up, facilitates and improves the preparation of raw materials for plastic molding, which ultimately improves the quality of the finished product. Loading and unloading of the obtained mixture from the mixer for polymers can be performed manually, or automatically, with the help of vacuum loaders. It is also possible to combine the mixer with an extruder or injection molding machine.
We offer the most common vertical and paddle mixers as well as fully automated polymer mixing systems based on your needs. Our company works with reliable partners who cooperate with the world's largest companies, so we are confident in the quality of the equipment we provide.

Our company works with a large number of suppliers of gearboxes and motors and will help you to choose the equipment you need based on your requirements. We also have the option of manufacturing equipment according to your specifications.
Blades and dies plates
The offered blades provide excellent cutting ability and long service life due to their excellent wear resistance. Raw materials from well-known manufacturers such as Bohler, Era Steel, Crucible Industries etc. are used to ensure product quality. All blades undergo a vacuum hardening process.
Also, it is also possible to produce custom-made dies according to the specifications and requirements of the end-use. The dies are equipped with tungsten carbide inserts and lined with stellite / chromium carbide.
BLADES
Blades are components in the plastic pelletizing process, enabling precise cutting and shaping of molten plastic strands into uniform pellets. Their design features, including high- quality materials and precise geometries, offer advantages such as accurate cutting, increased productivity and extended blade lifespan. Proper maintenance practices ensure optimal performance and reliability of BKG blades, contributing to efficient plastic pellet production.
DIE PLATES
Dies are components in the plastic pelletizing process, enabling precise cutting and shaping of molten plastic strands into uniform pellets. Their design features, including high- quality materials and precise geometries, offer advantages such as accurate flow of material form the extruder into the die head, increased productivity.

Whole screws and cylinders
Screws
We can meet all the requirements of our customers with years of experience in screw production. The screws can be shaped on the basis of customer wishes and solutions can be produced by making necessary studies to solve the problems. Screws get the right shape by using the appropriate design and appropriate production method.
Barrels
Barrel design is as much a matter of knowledge and experience as screw design. Barrels are not only a simple element that screws work in, but they are as effective as a screw in the rise of production capacity. In our CNC machines with the latest technology, we produce the barrel which can get the highest capacity.
Bimetallic coating
Bimetallic coating technology is applied to new screw or to screw which is required to be revised. The lifetime of the screws is increased by this coating which is made using different methods.
The main feature of bimetallic barrels is to provide high abrasion resistance. Bimetallic barrels lifetime is 3 to 5 times longer than standard nitration barrels. Apart from that, bimetallic barrels should be used for the use of magic materials that may cause exclusive wear, such as high filler CaCO3 or fiberglass. Also, bimetallic barrels should be preferred for high speed extruders with high capacity. Looking at the price performance, it will be seen that the bimetallic barrels are much more economical.
Heat treatment
One of the most important factors determining the service life of the screw and barrel is the correct heat treatment technology. The most precise heat treatment that can be applied to screws and barrels made of nitrided steel is gas nitriding. This is the coating used on the screws and barrels supplied by us.
