Hemetec, thanks to the collaboration of a company in the field, is able to offer a very versatile and precise machine for lines which require automatic pouring cars to increase productivity in the area dedicated to casting.
The machine can be combined with automatic ladle exchange system and there are different options available

The sizes range from 150 kg to 1500 kg of metal to be cast

Below is a list of the main features

• Dimensions: The automatic pouring system is normally produced with ladles ranging from 150 to 1500 Kg of metal to be cast.
• Automation: all functions and machine controls are made through on-board industrial PC. The operator on board the machine performs only the functions of the supervisor during all process stages in automatic.
• Fixed pouring point : the casting point remains fixed during the whole phase of casting. The fixed point can be easily changed from the control panel, depending on customer needs.
• Weighing system: the machine is equipped with a load cell system for casting the exact amount of metal. This ensures high precision on weight control.
• Controls: The controls of the machine are easy to use and ergonomic. The operator is in the cabin and has easy visibility throughout the melting process. The cabin can be equipped with air conditioning.
• Casting speed: The machine can adjust the scale of the casting speed in kg / sec.
• Minimum dimensions: the ladle protruding from the casting tank. Neither pins nor piles interfere with the possible positions of the ladle spout on the casting box.
• Good visibility: The carrier cabin is equipped with ample proof glass and oriented in all directions so as to allow the operator full visibility throughout the process.
• Structure: the whole machine is designed according to the strictest safety standards.
• The ladle: the ladle is produced with a form that is suitable for the spheroidization. It can be installed via forklift or gantry cranes.
• Ladle beak : the beak of the ladle is designed and produced according to requirements of our customers. Our ladles may have an additional beak which is opposite to the first; Extra beak is useful for the slagging process.
• Ladle lid: the ladle can be prepared with a lid to enable a constant temperature of the metal.
• ladle exchamge : the machine can be coupled to an automatic ladle exchange system . The machine leaves the empty ladle on a rotary station and takes a new ladle in very short times.
• Pre-heating of the ladle: a ladle pre-heating system may be arranged on the rotating station.
• Pyrometer: according to the requirements, the machine can be arranged with a pyrometer or, alternatively, a thermal imaging camera.
• Inoculation: the machine has an optional micro-dosing system for inoculation that starts and stops automatically during the casting process.
• Interfacing with the existing line: our automatic pouring cars can be easily interfaced with the molding / casting lines for data exchange. The machine can therefore automatically learn from the existing line of the model recipe that you will run

Hemetc is one of the most advanced European companies specialized in the design, prototyping and production of tooling with high technological content for the world's foundries and in the majority for the automotive sector.

The services offered are:

• Engineering according to specifications dictated by the customer: The great technical expertise, he has led designers to a very high level of specialization.The ability to understand and better manage customer needs, together with the degree of confidentiality of information collected, it involves the optimization of the production process.Optimize means to verify the feasibility of the project and make, in agreement with the customer, the appropriate modifications, thanks to which you will get benefits during subsequent stages of production, processing, use and maintenance.The production process is realized with the aid of the most modern and powerful technologies available on the market.Using the best CAD systems technical department develops the project that, once validated by the customer, is made available to the following departments that deal with "translate" actually what until then was a 3D model.

• Simulation with the most advanced systems that allows to highlight a preview of the equipment behavior and the end result of the casting in order to obtain a metallurgically result conforming to the customer's standards.
• Production: The 3D model is engineered and prepared for the next phase of processing by the CAM, which is responsible to make it usable for the subsequent manufacturing process that takes place in the workshop.
  The 3D model becomes useful and necessary tool to machine tools during the entire production cycle.
  The CNC flanked by a CAM workstation machines receive the 3D model and operators, highly skilled, process the tool path depending on the work to be carried out, becoming an active part in the decision of the setting  of the tool path 

• Testing: The fidelity of the 3D model reproduction is guaranteed by testing.Through the use of software, machines and optical measuring technology testing department acquires the 3D model and compare the dimensions defined in the virtual project with the real ones, highlighting deviations from tolerances.The audits are carried out throughout the entire manufacturing process in order to ensure the correspondence of the functional layout, inside the production line of the customer.The equipment delivery to the customer is accompanied by a complete copy of the technical design and dimensional inspection report. Such documentation has the purpose of the product and, in particular, the maintenance operations.

• Samples of finished products with certification: production of small series of samples in order to ensure the effectiveness of the equipment to the customer, further certified dimensional measurement performed on the prototype
• Assistance in testing at the customer

Hemetc has reached an agreement with a partner company in Tianjin and we are able to offer even complex control panels and equipped with all the desired standard of our customers.
