September 3, 2008
The Valencian company Raorsa has held a day of demonstration to publicize the electric machines of the Japanese brand Hitachi Toyo to those who have turned more than a hundred visitors. Universal plastics attended the day to chat with David Ortega Luque, son of the founder of Raorsa and current technical engineer. Raorsa has developed itself from a few early dedicated to the technical service, which is today one of the pillars of his philosophy. As points out Ortega, Raorsa is a company that premium service to the client. "We are a service company." "We are seeking to install a machine at home of the client and that it does not have any problem". In addition, each machine has an emotional burden on the workers of the Valencian company, and, were themselves who devised the concept of the hybrid machine and the new Energy of Euroinj series.
Make a brief introduction of Raorsa and the Toyo brand, since when her account?, what are its main features?
Raorsa machinery, S.L. It is a company dedicated to the marketing of machines for injection molding with more than 25 years of experience in the sector that has always been characterized by an excellent treatment of customers and unbeatable technical assistance, characterized by its speed and quality of service.
Since Raorsa has always chosen to offer their customers a product in accordance to the demands of the market. Up to 5 different types of injectors can be found currently in its catalogue: standard, hybrid, electrical, energy and economic savings.
Since the beginning of 2008, Raorsa is responsible for distribution throughout the Spanish of the electric machines produced by the Japanese manufacturer Toyo, company belonging to the Hitachi Group with 50 years of experience in the construction of injection molding machines and more than 25 years in the development of electrical injectors. With an annual average production of more than 3,000 electric injection machines, Toyo is consolidated as one of the most important firms in the world in the construction of this type of injectors.
The reason for the day is to introduce the fourth generation of Toyo fully electric injectors in what?
Thanks to the studies made by Toyo in collaboration with the University of Kyoto, has been to realize the fourth generation of electrical injectors of this brand, called Plastar Si-IV.
Main new feature it should be noted the system of 'Closing in V' with an angle of incidence of 7.5 degrees that allows the clamping force of form more uniform to the center of the mold. Also fixed and mobile dishes have been redesigned to better distribute the load. Increased the size of the dishes in small machines to speed both opening and closing of expulsion has earned.
"Saving energy of the Toyo injectors can reach up to 80 percent with respect to the use of a hydraulic injection of up to 7 per cent and conventional machine if compared with the rest of electrical injectors"
It has also improved injection unit. The Centre of gravity of the same lies on its horizontal axis allowing the support of the same on roller skates and optimizing in this way the movement of injection and loads to reduce friction. Also have focused support of the Group of injection on the fixed plate to prevent the inclination of the latter at the time of the injection.
It has been incorporated to this new generation driver PLCS-12, fully touch screen 12 "and a very simple and intuitive navigation system that allows to manage data from a mold from only a screen, as well as improved registration of production data. Also the control of the servo system has been enhanced optimizing the accelerations and decelerations allowing faster and more precise movements.
Finally, we must highlight on this new series of machines Toyo the soundproofing of broadcasting which reduced by 8.1 dB the sound level of the fuel transfer.
A company dedicated to the technical service
Raorsa was born 25 years ago with the figure of the father of David Ortega Luque, Rafael Ortega Sanchis. It began offering technical service for injection machines and even machines of the metalworking industry, especially in the area of the Levant. Later, they began to rebuild used machines. More than twelve years ago, Raorsa had the opportunity to represent the Taiwanese Euroinj brand. "People believed in ourselves because we have always responded to our customers," concludes Ortega Luque.

What forces of closure included the new range of injectors?
12 Are different models of injectors comprising series Plastar Si-IV of Toyo, whose forces of closure are between 490 kN of the model B-50IV to the 8330 of the if-850IV model. But in the injectors Toyo expands the range of options thanks to the possibility of choice of the various units of injection that can be combined with each of the groups of closure. The catalogue comprises 23 units which vary from the 13 cm3 of capacity of theoretical injection that can inject the B75B drive model until the 4752 cm3 in the unit of injection M750B.
It is known that the electrical injectors allow energy savings, how much savings are we talking about?
Currently, the savings of electric energy of Toyo plastic injection machines is considered that you can reach up to 80 percent with respect to the use of a hydraulic injection of up to 7 per cent and conventional machine if compared with the rest of electrical injectors. This energy-saving should be added the savings involved does not require a cooling system for the oil, as is the case in the hydraulic machines. It must be borne in mind that the consumption may vary depending on the time of cycle, weight of the product and material used. As curiosity can highlight a test with a Si-80IV whose power consumption not more than 0,85 kW/h, which means that the power consumption of the fuel transfer was similar to the of a domestic vacuum cleaner.

In Spain and in Europe, there is still some resistance to the electrical injectors. How is it evolving in Spain? They are slowly changing customers or still costing much?
Unfortunately, in recent years the European market has seen first-hand how many electrical injectors have not completed to the results that the builders promised. This fact is causing hesitation by the inyectadores when purchasing an electrical machine but, nowadays, many Japanese firms that are opening up market in Europe with excellent results. Toyo, with more than 25 years of experience in this type of machines, has been achieved in the 2007 be the best-selling Japanese electric machine in the difficult Italian market.
These data given to understand that the reluctance of the inyectadores towards this type of machinery are increasingly less, many customers are becoming aware that the future of the injection tends to ignore the totally electric drive machines and there are many who have in mind incorporating soon fuel a transfer of this type.
We believe that every year, sales of electric machines will grow more and more and in the not too distant future will outstrip even the hydraulic machines
Why they recommend an electric machine to your customers?
The advantages of acquiring a Toyo electric machine, starting with the considerable saving of electricity this kind of machines involved are more than evident. It must also take into account the low sound of these machines, low fat intake as well as cleaning not to use oil for their functioning.
These machines are fast, accurate, stable and of a quality and extraordinary reliability.
The incorporation of an electrical machine in a production process is a step towards the technological evolution of any company and the investment in new technologies that provide the company an excellent image.

Which profile do the clients of the Toyo injectors and which sectors are?
Any kind of producer may acquire a fuel transfer Toyo, from those who need to work at a fast pace, as technical parts manufacturers, producers of packaging, etc. The characteristics and qualities of these injection machines allow break through in any of the sectors.
What assessment can do hours?
More than 100 attendees on day of demonstration of the Toyo electric machines have seen first hand the operation of the if-230IV F400B injectors working in conjunction with a robot alpha and fuel transfer if-130IV F200B.
Visitors have been surprised the functioning of these injectors, of quick, the smoothness with which act all the movements, the repeatability at all levels, its low sound and especially its low power consumption, as it has been observed that this not more than 5'2 kW/h in the fuel transfer if-230IV.
During the day were the electric machines of the Toyo Hitachi Group, where attendees were able to observe first-hand the functioning, benefits and advantages of the models Plastar Si-230IV - F400B and Plastar Si-130IV - F200B.
Fuel transfer Hitachi Toyo
"Given that the main concern of the Toyo machine manufacturer is environmental, machines have been designed so that the environmental impact that can cause on the environment is the minimum." Therefore these injectors are characterized by its low consumption of grease lubrication, its low sound and above all for its speed of cycle and its considerable saving of energy expenditure; "all of this together with the simple handling of their control, the reliability of all its components and benefits presented make this machine ideal for the majority of the production processes".
