The hand layup technique is the simplest process for making parts from synthetic resins reinforced with fiberglass, being used for small series of parts. The advantages of this process are the relatively low cost of making the machines, the ease of their production, and on the other hand, special attention must be paid to implementation, because, being a process par excellence manual, requires a fairly specialized staff. Tools and various utensils are easy to procure, but as easy as this process seems, it is as difficult to obtain parts without the slightest surface defect.
