Recommended: Injection molding research paper

Injection molding is one of the most common processing methods for thermoplastics. In present day scenario we can find different types of injection molded products in homes, vehicles, offices and factories. These include combs, syringes, paintbrush handles, crash helmets, telephones, soft drink glasses, gearwheels, brief cases, television housings, typewriters—the list is almost endless.
This project aimed at the process redesign of an automotive component to reduce warpage using the MoldFlow simulation software. Optimization means to make something as good as possible efficiently. In this case, optimization of molding parameter is carried out to make improvement in the molding parameters that affects warpage during injection molding process.
The present day competitive scenario has made the production of plastic components at the most efficient way utilizing minimal resources and free of defects within as little time as possible, a necessity. Computer-aided analysis and engineering softwares provide an immense help for the industries to …show more content…

In manufacturing field, injection molding is widely used to produce a variety of parts, from the smallest component to biggest component. Injection molding is the most common method of production, with some commonly made items including bottle caps and outdoor furniture. Injection molding machines consist of a material hopper, an injection ram or screw-type plunger, and a heating unit. They are also known as presses, they hold the molds in which the components are shaped. Presses are rated by tonnage, which expresses the amount of clamping force that the machine can exert. This force keeps the mold closed during the injection process. Tonnage can vary from less than 5 tons to 6000 tons, with the higher figures used in comparatively few manufacturing operations [Tim et. al.,

  • The Future Of 3D Printing In The Medical Industry

    2308 Words  | 5 Pages

    3D printing has the potential to revolutionize the way we make almost everything. 3D printing was invented in the mid 1980s and was initially known as additive manufacturing. It consists of the fabrication of products through the use of printers which either employ lasers to burn materials (sintering) or place layer upon layer of material (known as stereolithography), eventually resulting in a finished item. Unlike the traditional manufacturing process, which involves milling, drilling, grinding or forging molded items to make the final product, 3D printing “forms” the product layer by layer. There are many different technological variants but almost every existing, 3D printing machine functions in a similar way: a 3D computer-aided engineering (CAD) file is sliced into a series of 2D planar sections and these are deposited by the printer, one above the other, to construct the part.

    Some of the issues presented above resulted from inefficiencies in the two distinct processes taking place in the same production facility at Custom Molds, namely the Molds Fabrication process and the Parts Production process (Exhibit 1a and b). The two processes serve different customer needs. Mold fabrication, a skill oriented and craftsman-driven process, requires flexibility and quality. Parts manufacturing, on the other hand, involves a more standardized process that competes on delivery and low cost. The margin for parts is also much smaller.

    CAD – One factor that is often overlooked when introducing this type of process into the manufacturing industry is having personnel trained in the appropriate operational software, such as CAD. When a 2D CAD image is created of the desired design what needs to be kept in mind is that this will also involve calculating bend allowances, inclusion of half etch detail and scaling. To allow for the etching process an etching compensating factor has to be taken into account. This includes drawing the outside profile larger than the finished component size this means holes and slots should be smaller to compensate. The amount of adjustment is directly proportional to the thickness of the metal being processed.

    The contraction moulding method can be used to process an acrylic denture base. In this method, bite blocks are fabricated in the lab and sent to the clinic for patient trial. These are then received from the clinic and teeth are mounted onto the bite blocks. The wax is eliminated and teeth are pressurized and attached onto a gypsum mould. (McCabe and Walls. 2008.) Sodium alginate is applied onto the mould to act as a separator to prevent any monomer from the acrylic base seeping into the base and the mould. Acrylic PMMA is applied onto the mould and either heat-cured or auto-polymerized. Both of these curing methods form the...

    Automotive manufacturing is the conversion of raw materials into finished products. It involves a variety of activities such as product design, material selection and handling, control and production, planning and procurement, inspection and quality, packaging, finance and sales. During the process, the key factors for an industry are its competitiveness and productivity over another industry which is command by the economy of manufacturer, the quickness and ease, of a quality product. These factors are important for any manufacturers who want to set their companies standards according to the increasing globalization of all aspects of product including mason, technology and market. Quickness, economy and quality in manufacturing in automotive manufacturing can be achieved by using automated machine. It is believed that it will reduce the human error using conventional machine and help in manufacturing complex automated parts and provide reliability and quality required for competitive manufacturing. While this thinking was not limited to a scope since fully automated factories uses hard automation system for manufacturing are not yet feasible due to practical, financial and cybernetic reasons.

    Much like an inkjet printer, a 3D printer “prints” a set of plans on a computer by using “additive manufacturing.” The additive manufacturing process builds objects layer-by-layer rather than through molding or subtractive techniques (such as machining) (McKinsey Global Institute, 2012). Additive manufacturing is attractive for producing items that are hard to find or when only a few like items are needed because the cost of production remains the same whether someone prints one or many, or if the item is old or new.
