Steel is usually described as being ________ and heavy, but very durable.

When a material is composed of two or more different materials mixed together, it is called

The composite material is expected to be rigid (not flexible).

The grinder is the last step before the assembly and checking dimensions.

The electric saw is used to bend the material into a curve.

Corrosion-resistant is an important property for this new machine part.

Materials Choice and Production Plan

Our team is designing a new part for a packaging machine. This part needs to be light to increase machine efficiency, but it must also be very strong and durable. We cannot use heavy Iron or basic зlastic. After some analysis, we decided that a сomposite material, reinforced with fibre, is the best choice. This material is both light and rigid, and it is naturally corrosion-resistant, which is important for long-term quality.

The production of this part involves two main manufacturing processes: cutting and shaping. First, the raw сomposite sheet must be precisely cut to the correct dimensions using an electric saw. Then, the part must be shaped to a specific curve. This requires us to carefully bend the material using a special press. Finally, we use a grinder to make the surface completely smooth. After all these steps, we drill three small holes for the screws needed for assembly. Every part must be checked with a caliper to ensure the dimensions meet the small tolerance required for the machine system.

The team chose Iron because it is lighter than the composite material.
