This is a process of manufacturing where in some parts or materials are being injected into a mold. This process is performed with the use of materials such as metals, elastomers, glasses, confections, and two most common which are the thermosetting and thermoplastic polymers. The material which is to be injected is being heated inside a barrel, it is mixed and then it is enforced into mold cavity where it will be hardened and cooled. The designing of products is made by an industrial engineer or designer and molds are manufactured by a mold maker or toolmaker.
Most of these are made out of metal, either steel metal or aluminum metal. To form the features of desired parts, precision machines are used. Injection molding now is widely used in manufacturing many types of components, wither small or big parts, such as in cars or the body panels. For simple injection, photo polymers or advanced 3D printing technology is used.
The parts that are to be injected must be carefully designed in order to properly facilitate the process of molding. These parts include the materials, features and shapes of the parts, and the materials and machine properties of the molds. Some uses of these type of process are for creating wire spools, bottle caps, and some automotive components and parts. This is the most common method for the production of plastic components.
Other materials such as polymers, often called as resins, may also be used. These also include some thermo sets and elastomers, and all types of thermoplastics. Examples of a thermosetting plastic are some common polymers like the phenolic and epoxy. And the examples of a thermoplastic are polyethylene, nylon, and polystyrene.
There are also materials like alloys and the blends of materials which are previously used are utilized as well. And for this reason, the designers can be able to choose from a variety of choices and it is important for them to choose the one with best properties. For the selection of material, functions and strength must be observed. These two are necessary for cost and production. The parameter of material is also important.
Machines that are used have heating units, screw or ram plungers, and hoppers. Machines are also known as pressers. The machine will hold a mold where in the components will be shaped. Presses are rated by means of tonnage. A tonnage is a clamping force amount that machines will exert. This force will help the mold keep closed during the process.
Molds in Cobourg, ON are built in either the standard machining and the electrical discharge machining. The standard machining is most typically used for building an injection mold. This became the primary means in building complex molds which have more accurate details compared to the traditional method.
The spark erosion or the EDM allows formation of the shapes which is hard for a machine to perform. It allows shaping a pre handed mold with no heat treatment as well. In this process, shaped electrodes are lowered slowly into surface of molds.
The costs would be highly dependent on the cavities which are integrated in the mold. So this means that if there are fewer cavities, it will require less work for tooling, which in turn will lower the manufacturing cost. The complexity of design will also affect the cost.
