| Based on rapid prototyping rapid tooling technology
Wood used in casting mode (see Figure 2). It features polished handle time-consuming follow-up, resulting in mold manufacturing cycle increased, the cost increase. La mode technology news then quickly llRT) spray gun used to spray mist to the RP prototype of the metal to form a hard shell about 2cm thick metal layer, to isolate down, with aluminum powder filled epoxy resin or silicone rubber is also supported Lc-and the prototype will be separated, l can be made into the injection mold cavity. Electroformed nickel shell mold for a ceramic backing the principle of it is electricity in the original cast of nickel shell mold formed on the surface, and then chemical bonding and composition of ceramic molds for backing. The original model of the materials can be plaster, wax, plastic, stainless steel, aluminum, non-metallic electrical conductivity of the original model is subject to treatment, methods of coating such as powder and conductive coating. Ceramic Casting kind of RP based on the prototype (positive type) can be turned into silica cavity (negative type), made of ceramic Zaifan (positive type); use of ceramic type can be cast is a metal (such as zinc-aluminum alloy, beryllium copper alloy) cavity (negative type) for injection molding, the use of SLS technology can be directly molded ceramic metal mold manufacturing. Produced by rapid prototyping of plastic prototypes, and then casting silicone rubber, but also oxygen resin, polyurethane and other materials to form soft mode; remove the prototype, in the soft mode in the pouring chemical bonding ceramic (CBC, ceramic matrix composites) to form the cavity, After curing at 205 ~ C the following cavity CBC and polishing the surface of the cavity, adding gating system and cooling system with a small batch obtained after injection molding. In the mass production of metal casting molds, the first prototype using RP or reproduced silicone rubber under the metal resin composite material made of wax or polyurethane molding die, and then using the wax molding production, and then wax casting process system Cheng Gang (iron) die, the production of complex parts in a single mold, RP prototypes can be directly used instead of wax. Low melting point alloy die temperature with no direct or indirect parent die casting metal mold, made low-fluxing model can be used to suppress the foundry sand core. Wang Ming ■ Precision Parts Co., Ltd. of business of the circle with: mold standard, widely used in precision plastic mold,mulberry helsinki, stamping die, the semiconductor die, die casting molds and other precision parts, etc. Address Dongguan Shijie Osmanthus Road Tel: 0769 - 87065258 Fax 0769-87065259Http / /: RP prototype using EDM electrodes used in the prototype using RP reproduction study with graphite electrodes, and then use translational research using grinding method with a graphite electrode manufacturing, and then use electrical discharge machining of metal mold. This is a graphite electrode forming method. Figure 9, the mold rapid prototyping and static j it is in the RP prototype products surface coating layer of conductive medium and electrical casting surface precipitation in the RP prototype of steel by a layer of a certain thickness of copper plating electrodes,mulberry oslo, re-use electrode spark processing mold. This is the electric copper electrode. Electrode forming method has the advantage with the increased complexity of the mold cavity, volume increases, the more they can be reflected in its advantages, Figure 9 for the production of rapid prototype molds and products.
