Laser Rapid Prototyping Technology (4) Laser cladding forming (LCF) technology Its working principle is basically the same as other rapid prototyping technologies. The difference is that laser cladding forming can make very dense metal parts, and its strength can reach or exceed the parts produced by conventional casting or forging methods, so it has a…
Rapid Prototyping Technology In Aerospace Technology In the aerospace industry, aerodynamic ground simulation experiments (ie, wind tunnel experiments) are an essential part of designing an advanced world-class round-trip system (ie, a space shuttle). The model used in this test is complex in shape, high in precision and streamlined. It adopts RP technology. According to the…
Application Of Rapid Prototyping Technology In Mold Manufacturing The current rapid molding methods generally include indirect molding and metal direct molding. Commonly used rapid molding methods are soft mold, bridge mold and hard mold. (1) Soft Tooling Usually referred to as a silicone rubber mold. The prototype made by SLA, FDM, LOM or SLS technology…
Injection Molding Learning 1. Rotating speed of the screw The rotational speed of the screw significantly affects the degree of stability of the injection molding process and the amount of heat acting on the plastic. The faster the screw rotates, the higher the temperature. When the screw rotates at a high speed, the friction (shear)…
Rapid Prototyping Technology Development Rapid Prototyping Manufacturing (RPM) technology is developing in two directions: one is the direction of direct manufacturing of parts, called rapid manufacturing (RM) technology; the other is combined with life science technology, called bio-manufacturing ( BM) technology. At present, both RM and BM technologies have shown broad development prospects, opening up…
Injection Must Learn Knowledge Points 1.Nozzle The melt usually flows from the nozzle into the nozzle, but with some molds, the nozzle is part of the mold because it extends to the bottom of the mold. There are two main types of nozzles: open shot nozzles and closed nozzles. In injection molding, open nozzles…
Sandwich Injection Molding The sandwich injection molding process injects a core material into the outer skin. The process takes place in two or three steps in one cavity. First, the material of the stroke surface layer is injected into the cavity portion space. The core component is then injection molded through its first material into…
Alternate Injection Molding Alternate injection molding alternately injects the same plastic component of two different colors into the same cavity. Both colors are placed in a special mixing nozzle before entering the mold. The two-color components are mixed to form a color effect. The two colors can be purposefully mixed to configure. In the alternate…
Composite Injection Molding And Core Retraction Process In the core retreat production process, the hollow portion of the mold is first closed and later reopened using a sliding core or slider within the cycle. When producing a part with two components, the first injection molding stage first injects the prefabricated component and then opens the…
Toughened Engineering Plastic The core-shell polymer particles are composite particles having a double layer or a multilayer structure composed of components having different chemical compositions or different aggregated forms. In 1957, Rohm & Haas of the United States first developed a core-shell polymer of the trade name K120. In the 1960s and 1970s, companies such…
