Cube Mold Technology
Cube mold technology (also known as Rotating cube mold technology or Stack-turning molding) is a molding process for the manufacture of plastics components. This molding process allows to manufacture circular parts. This technology was introduced by Foboha (a business unit of Barnes Group) and Arburg. Basic concept The cube mold technology is characterized by components that rotate vertically round the axis. The lower section of the mold runs on the machine base and the lower machine tie bars. The top section of the part runs on the upper machine tie bars. In this technology, components are molded within the rotating system at different steps. Below are the different steps- *The initial moldings are performed in a cavity of the first parting line. *When mold is fully open, components remain on the side of the movable middle block and can be turned into the range of the second parting line by a 90° or by a 180° turn of this middle block. *After the mold closes again, the sec ...

Injection Moulding
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers t ...

Molding (process)
Molding (American English) or moulding ( British and Commonwealth English; see spelling differences) is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix. This itself may have been made using a pattern or model of the final object. A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object. Articulated molds have multiple pieces that come together to form the complete mold, and then disassemble to release the finished casting; they are expensive, but necessary when the casting shape has complex overhangs. Piece-molding uses a number of different molds, each creating a section of a complicated object. This is generally only used for large ...

Direct Injection Expanded Foam Molding
Direct injection expanded foam molding (also known as ''injection molded foam'') is a manufacturing process that creates soft foam products direct from a compound into a final product. This process eliminates the steps normally required for die-cutting and compression molding, because it manufactures the foam and the product, simultaneously. The base resin, used in a complex formula, is an ethylene-based polyolefin elastomer (like polyethylene and EVA). Foam that is manufactured with these resins has many physical benefits. Unlike a sponge, foams from this process are closed-cell, meaning it's waterproof and resists mold, mildew, and bacteria from entering the material. It is also cross-linked, which means that the cells are connected in a way that makes the foam strong and durable with high tear and tensile strength. All polyolefin elastomers are also resistant to most chemicals, which allows the products to not only be used in a chemical environment but also with most hou ...

Fusible Core Injection Molding
Fusible core injection molding, also known as lost core injection molding, is a specialized plastic injection molding process used to mold internal cavities or undercuts that are not possible to mold with demoldable cores. Strictly speaking the term "fusible core injection molding" refers to the use of a fusible alloy as the core material; when the core material is made from a soluble plastic the process is known as soluble core injection molding. This process is often used for automotive parts, such as intake manifolds and brake housings, however it is also used for aerospace parts, plumbing parts, bicycle wheels, and footwear... The most common molding materials are glass-filled nylon 6 and nylon 66. Other materials include unfilled nylons, polyphenylene sulfide, glass-filled polyaryletherketone (PAEK), glass-filled polypropylene (PP), rigid thermoplastic urethane, and elastomeric thermoplastic polyurethane... History The first patent for this type of molding process was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metal Injection Molding
Metal injection molding (MIM) is a metalworking process in which finely-powdered metal is mixed with binder material to create a "feedstock" that is then shaped and solidified using injection molding. The molding process allows high volume, complex parts to be shaped in a single step. After molding, the part undergoes conditioning operations to remove the binder (debinding) and densify the powders. Finished products are small components used in many industries and applications. The behavior of MIM feedstock is governed by rheology, the study of sludges, suspensions, and other non-Newtonian fluids. Due to current equipment limitations, products must be molded using quantities of 100 grams or less per "shot" into the mold. This shot can be distributed into multiple cavities, making MIM cost-effective for small, intricate, high-volume products, which would otherwise be expensive to produce. MIM feedstock can be composed of a plethora of metals, but most common are stainles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi-material Injection Molding
Multi-material injection molding (MMM) is the process of molding two or more different materials into one plastic part at one time. As is the case in traditional injection molding, multi material injection molding uses materials that are at or near their melting point so that the semi-liquidous (viscous) material can fill voids and cavities within a pre-machined mold, thus taking on the desired shape of designed tooling. In general, advantages of MMM over other production techniques include, but are not limited to, creating parts that have an elastic modulus that varies with location on the part (different regional polymer hardness), creating a single-structure part with different regional materials (similar to the previous advantage, but more focused on joining different types of polymers like rubber and plastic), and also creating a single part with multiple independent polymer colors. Applications range from simple household items like a toothbrush to more heavy duty constructi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reaction Injection Molding
Reaction injection molding (RIM) is similar to injection molding except thermosetting polymers are used, which requires a curing reaction to occur within the mold. Common items made via RIM include automotive bumpers, air spoilers, and fenders. Process The two parts of the polymer are mixed together, usually by injecting them under high pressure into an impinging mixer. Then the mixture is injected under lower pressure into a mold. The mixture is allowed to sit in the mold long enough for it to expand and cure. If reinforcing agents are added to the mixture then the process is known as reinforced reaction injection molding (RRIM). Common reinforcing agents include glass fibers and mica. This process is usually used to produce rigid foam automotive panels. A subset of RIM is structural reaction injection molding (SRIM), which uses fiber meshes for the reinforcing agent. The fiber mesh is first arranged in the mold and then the polymer mixture is injection molded over i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas-assisted Injection Molding
Gas-assisted injection molding is a molding process where an inert gas is injected into the melted plastic pushing it further into the mold and resulting in hollow parts. Basic concept The basic concept of the gas-assisted molding process is quite similar to the regular injection molding process. In gas-assisted molding, the plastic material is injected into the mold cavities like the regular injection molding process but only up to 70%~80% of the mold volume. The melted plastic in contact with the mold walls begins to solidify, then nitrogen gas is injected into the mold through strategically designed and placed gas inlets, providing pressure that pushes the plastic into the mold extremities. The path of the bubble is controlled by taking the path of least resistance through the hottest, least viscous plastic, which keeps it centered from the colder walls of the mold. Finally the molded part is ejected like the regular injection molding process. Advantages This process f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micro Injection Molding
Micro injection molding is a molding process for the manufacture of plastics components for shot weights of 1 to 0.1 grams with tolerances in the range of 10 to 100 microns. This molding process permits the manufacture of complicated small geometries with maximum possible accuracy and precision. Basic concept The basic concept of the micro injection molding process is quite similar to the regular injection molding process. In this process, a micro injection unit is integrated in the injection molding machine. When it comes to the production of micro components the machine and process technology mainly depend on the below points: *Short dwell time *Low shear stress on the polymer melt *Homogeneous material preparation before molding *Precision injection and ejection *Accuracy of dimensions Critical factors Parting line issue A parting line (PL) is the line of separation on the part where the two halves of the mold meet. The parting line matching for micro parts is a big is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
