Injection Molding of Plastics (3089-IM)
Injection Molding of Plastics
Injection molding uses a ram or screw-type plunger to force molten plastic material into a cavity; this solidifies into a shape that has conformed to the contour of the mold. It is most commonly used to process both thermoplastic and thermosetting polymers, with the volume used of the former being ...

Bearings & Linear Motion (3562-LM)
Llinear motion and linear postioning systems with travel lengths and carriage forces are designed to accommodate a broad range of application needs. Linear bearings, sometimes called track runner bearings, are part of a system suitable for use in precision linear motion applications, such as in printing machines and computer numerical control (CNC) equipment. Other system components include glide shafts, support rails, and glide blocks. A linear bearing may have different types of rolling elements, such as for linear ball bearings and linear roller bearings. In corrosive environments, Torlon® roller bearings resist corrosion and wear for long life. When choosing a linear bearing, consider the environment in which the linear motion system operates, as well as the axial and radial loads the system carries. By utilizing wear-resistant engineering plastics to replace metals, the use of oil seals and lubrication systems may be eliminated in some cases. Materials such as Turcite® are commonly used on anti-backlash lead screws. Other wear-resistant bearing materials include; Delrin® AF, Nylatron®, Torlon® 4301, Vespel®, Rulon®, & more.
