Problems To Be Solved In Rapid Mold Manufacturing Based On RP The use of RP technology to develop rapid mold manufacturing technology still has the following major problems, which need to be solved or need to be further improved. (1) How does the surface quality meet the requirements of the mold, otherwise it cannot withstand…
Rapid Prototyping Technology The application of rapid prototyping technology has evolved from prototyping to mold making, bringing new vibrancy to traditional mold making technology. At the same time, the successful application of rapid prototyping technology in the field of rapid mold manufacturing will undoubtedly inject new vitality into the further development of rapid prototyping technology.…
Tungsten Argon Arc Welding 1. Scope of application Tungsten argon arc welding can weld almost all metals and alloys, but due to the high production cost, it is generally only used for welding stainless steel, heat-resistant steel and non-ferrous metals such as copper, titanium, aluminum and magnesium. For metals with low melting point (low boiling…
Indirect Mold Casting Method (1) Ceramic type precision casting method This method can be used when producing steel molds in a single piece or in small batches. The process is: RP prototype as the master mold → dipping ceramic mortar → curing the mold shell in the oven → burning the master mold → preheating…
Molding Of 3D Products (1)Discrete processing (slice processing) After the production (stacking) direction is selected, the three-dimensional solid model (generally the STL model) is one-dimensionally discrete by a dedicated layering program, that is, layered and sliced along the production direction, and the profile of each thin layer is obtained. Entity information. The thickness of the…
Rapid Prototyping 3D Model Construction According to the drawing or design intent, the CAD entity file of the part is designed in the 3D CAD design software. The file output format supported by general rapid prototyping is the STL model, that is, the so-called surface treatment for approximating the solid surface, which is to approximate…
Indirect Molding Method The direct molding method can use different materials in different parts according to requirements. However, the direct molding method is limited by the process itself, and the manufactured mold cannot meet the requirements of high-precision metal molds in terms of surface and dimensional accuracy, size, and shape freedom. The competitive rapid molding…
Mold Making Method Based On RP Technology The traditional mold manufacturing methods can be divided into two types, one is to use the master mold to reproduce the mold, and the other is to directly mold the mold with a numerical control machine tool. In the new product development process, reducing the cost and time…
Direct Molding Method 1.SLS laser powder sintering The general process is as follows: firstly layer a layer of powder on the substrate, and after pressing the roller, a layer is selectively sintered by a laser. A new layer of powder access paving device is then placed over it, and the next layer of sintering is…
Features Of Rapid Prototyping 1. Freeform manufacturing Freeform manufacturing is another term for rapid prototyping. The meaning of free-form manufacturing as one of the characteristics of rapid prototyping technology has two aspects。 First, it is not necessary to use a tool to make a prototype or a part, thereby greatly shortening the trial production cycle…
