SLA Laser Rapid Prototyping The SLA process, also known as light modeling or stereolithography, works on the principle of photopolymerization of liquid photosensitive resins. The liquid material can rapidly undergo photopolymerization under the irradiation of ultraviolet light of a certain wavelength and intensity, and the molecular weight sharply increases, and the material changes from a…
DetailsRapid Prototyping Six Mainstream Analysis Of Technical Features 1.InkJet inkjet three-dimensional printing technology A method of curing a device by ejecting viscous ink through an inkjet printhead, attaching it to the powder particles, and bonding the particles. 2.SLA light curing molding method The ultraviolet laser is controlled by a computer, and the spot-by-point scanning is…
DetailsResearch On Laser Rapid Prototyping Technology Of Metal Parts There are various researches on laser direct rapid prototyping technology for foreign metal parts, including Laser Engineered Net Shaping (LENS) forming process and Laser Forming (Lasform) forming process. Directed Light Fabrication (DLF) technology and shape deposition manufacturing technology forming process research. Direct Metal Deposition (DMD) and…
DetailsLaser 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…

The model used in this test is complex in shape, high in precision and streamlined. It adopts RP technology. According to the…
DetailsApplication 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…
DetailsInjection 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)…
DetailsRapid 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…
DetailsInjection 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…
DetailsSandwich 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…
