  • Publication number: 20200198233
    Abstract: A 3D printing technology-based processing apparatus and method includes a frame, an injection unit, and a molding unit. A melted polymer filler can be filled into a blind hole or a passageway of a 3D printed product to improve overall strength of the product. A 3D printed product having a mortise and tenon shaped mechanical engagement structure is disclosed. The printed product having the mortise and tenon shaped structure has higher tensile strength and shear strength. The present apparatus effectively resolves a problem of warped and deformed products due to an excessive temperature difference between the product and an environment during printing. The method uses an optimized printing process to reduce the fabrication processes of a support structure, reduce consumables required for building the structure, and improve the printed surface quality of the printed product.

  • Patent number: 9827725
    Abstract: A tire direct-pressure shaping and electromagnetic induction heating curing method uses an inner metal mold including large and small segments, a telescoping mechanism, supporting plates attached to the segments, and induction heating coils. A cavity in the middle of the segments is filled of phase change material. The temperature of the mold rises rapidly by the thermal effect of an eddy current generated on the surface of the segments to heat the green tire. When the middle part of the segment is heated to a certain temperature, the phase change material absorbs and stores the excess heat. Therefore, the temperature of the middle part of the segment differs from one of two ends of the segment. Once the tire is cured, the inner mold in the expanded condition and the outer mold support very high pressure for the green tire together.
