Mold Design for Rings of External Fixator

Popis výsledku v původním jazyce

This paper deals with a structural design of a mold for making a composite ring of external circular fixator used in medical applications. It also focuses on the choice of technology and material for the production of a fixator ring. Due to the high demands on the quality, appearance, material of the product and higher series production, autoclaving was chosen for this purpose. Thanks to this sophisticated production process, the high quality and accuracy of the ring can be achieved. The starting material for the production of composite components is a layer of resin-saturated fibers, abbreviated prepreg. This blank is cut on a CNC plotter and embedded into a mold for molding. The mold is provided with a separator and a filler of pores. The resulting surface quality of the product then depends on the surface of the mold, the selection and the careful application of the separator (gelcoat), which also affects the life of the mold. For easier machining, aluminum was chosen as the material of the mold. The result of this contribution is the choice of the material of the product, the appropriate technological process and the design of the mold to obtain the resulting product which meets the required mechanical properties, appearance and functionality requirements.
