ABS plastic is a low-cost engineering plastic it is easy to machine and fabricate it is ideal material for prototyping this material is machinable rigid and relatively impact resistant. ABS plastic is widely used in the industry for preproduction prototypes due to its structural stability it is easy to paint and glue and it is widely used in food service processing applications.

Electrical steel, also called lamination steel, silicon electrical steel, silicon steel or transformer steel, is specialty steel tailored to produce certain magnetic properties, such as a small hysteresis area (small energy dissipation per cycle, or low core loss) and high permeability.

The material is usually manufactured in the form of cold-rolled strips less than 2 mm thick. These strips are called laminations when stacked together to form a core. Once assembled, they form the laminated cores of transformers or the stator and rotor parts of electric motors. Laminations may be cut to their finished shape by a punch and die, or in smaller quantities may be cut by a laser.

PVC is a durable plastic and available in many shapes it is commonly available in two grades type 1 it is normally used in applications where corrosion resistant properties are important this grade offers protection from acids and alkalines in high concentrations. This material working temperature is 140°F or below ,type 1 material are not used in environments that the material is excessively physically abused PVC type II is useful in thermoforming, where: two or definition and surface texture are important factors.

POLYCARBONATE

Polycarbonate is a durable thermoplastic with a high heat deflection capability. This material is to use in applications like safety shields and sports equipment, Polycarbonate can also be machine to close tolerances this material can be transparent and is manufactured in sheets and cylindrical hollow tubes. this is a durable material.
