Plastic is a very popular material used to make various machine elements. The most popular details include: maltese mechanism, turntables, railings, wheels, handles. The material is selected individually in terms of mechanics of operation and required parameters of work for a given part. As a rule, machine manufacturers determine the type of material to be used to make a given mechanical part.

However, the choice is often not obvious and then we help with the selection.

The selection of material requires the definition of many parameters, of which the basic ones may include:

• environmental conditions,
• the way of working/cooperating with other parts,
• load,
• the work cycle.
