Japan's trade surplus small injection molding machine developed

According to the Nikkei report, resin molding technology development in emerging Sellbic Japanese company has developed a special resin for small parts forming the "CMobile" ultra-compact injection molding machine. Molding can be as little as 1 gram of weight below the weight of the machine itself is very light and can carry hand-held mobile.
     The company said that in order to use the least amount of resin molding, to avoid waste of materials and energy, developed a "CMobile" injection molding machine. The biggest characteristic of the aircraft will be generally set the end of the hot runner in the mold set in the device side. Hot runner molds used for the Department of flow in the heating and flow of materials to maintain the molten state. As expected condensate flow does not produce, it can reduce the amount of resin. Hot runner mold with the general will increase the cost of nearly 100 million yen, while the new machine not only reduces the tooling cost, but also for no flow and the gate of the molding process.

     In order to achieve small, screw into the flat shape. Cut a spiral groove on the plate, the resin can flow from the outside in a trench in the center of the screw and the corresponding shear stress is applied between the mold plate, you can mix resin.

     Machine also set the resin into the mold plunger.

     The benefits of using flat screw machine not only can achieve the miniaturization. General screw to ensure durability, increasing the surface coating to improve the hardness. Even so, if the glass fiber forming resin, then still need to be replaced twice a year or so. The result of the molding machine screw with flat, can be quenched, so you can be sure to use about 10 years, in the middle do not need to be replaced.

     Emerging Sellbic also independently developed by the motor-driven screw cycloidal reducer. Cycloid tooth is said to own the company's processing center for processing, transmission efficiency can reach 85%.
