Spanish term or phrase: preforma
Estoy trabajando en una traducción sobre elaboración de botellas plásticas. La compañía en cuestión fabrica preformas y envases. Encontre dos traducciones para preforma:

Parison
Preform

Mi pregunta es cual de las dos deberia utilizar? Hasta el momento habia utilizado parison pero me queda la duda y me gustaria escuchar sus opiniones.

Mil gracias

Pareciera que en algunos casos usan preform como sinónimo de parison.

Te incluyo la definición de preform tomada de Wikipedia:

"The preform consists of a fully formed bottle/jar neck with a thick tube of polymer attached, which will form the body."

El parison corresponde a la etapa inmediatamente anterior, cuando aún no tiene forma:

"In Extrusion Blow Molding (EBM), plastic is melted and extruded into a hollow tube (a parison). "

Otra definición de preform (Whittington's Dictionary of Plastics):

"A compressed, shaped mass of plastic material or fibrous reinforceing material or a combination of both, prepared in advance of a molding operation for convenience in handling or for accuracy of loading by weighting the mass".

En el caso de las botellas de refresco, las preformas tienen la rosca del tamaño que es, pero el resto de la preforma es una especie de botella en miniatura (de unos 10 cm de largo según mal no recuerdo) y con espesor de pared mucho mayor.

Definción de parison según el Whittington's Dictionary of Plastics:

"The hollow tube or other preformed shape of molten thermoplastic that is inflated inside the mold in the process of blow molding. Most commonly, the parison is extruded immediately before blowing, but parisons are also injection molded and may also be chilled and stored to be reheated before molding."

De acuerdo a esta definición, pareciera funcionar esta acepción también. Sin embargo, recuerdo haber usado los términos parison y preforma en español y no de forma sinónima. Averiguo un poco más y te aviso.

Pre forma


Explanation:
Para envases de refrescos se identifican como preforma, ya viene el diseño del envase solamente corresponde inyectarle aire a presion y calor dentro del molde para llevarlo a su forma final.

Mientras que en el parison el material fundido no tiene forma, solo esta diseñado en el panel de control para que sea distribuido su peso a todo lo largo de la manga (parison) para luego consolidarlo dentro de un molde y llevarlo a su forma final.
