`
`evenly, and the ability to endure sustained production
`withoutconstant maintenance. Using low-cost material to
`meet high performance requirements will compromise
`mold integrity. For example, for more than 90% ofthe
`molds, the cost of the cavity and core materials is less than
`5% ofthe total mold cost. See cost, product; mold cost.
`mold cavity, debossed. Depressed or indented let-
`tering or designs in the cavity that produce bossed impres-
`sions on the molded part. See decorating, fill-and-
`wipe.
`mold-cavity deposit A plastic build-up on a cavity’s
`surface that is due to plate out of the plastic and usually is
`attributed to the use of certain additives.
`mold-cavity draft On most molded parts, features
`mustbe cutinto the surface of the mold perpendicular to
`the moldingpartingline. To properly release the part from
`the tool, parts almost alwaysincludea taper. The amount
`of mold draft required will depend onfactors such as type
`ofplastic being processed, processing conditions, and sur-
`face finish. For example, a highly polished surface will re-
`quire less than an unpolished mold. Any surface texture
`will increase the draft at least 1° per side for every 0,001
`in. (0.003 cm) depth oftexture. Special mold-cavity sur-
`face action can be used. Elastomeric material has a rubbery
`condition and maynotrequire the draft for ejection. Also
`called draft in the direction of the mold. See mold-parting
`line; mold release agent.
`mold cavity, duplicate-plate A removable plate that
`retains cavities and is used where a two-plate operation is
`necessary for loadinginserts.
`mold cavity, etched A surface that is treated with an
`acid, leaving relief to form the desired design texture on
`the moldedpart. See chemical etching; photoetching
`tool; surface treatment; texturizing.
`mold-cavity ejector Various mechanical means that
`are used to eject or remove the molded part from the
`cavity.
`Theindentedhalf of a mold that

`is designed to receive the male half. See mold cavity,
`male.

`boost cut-off or two-stage control.

`mold cavity,
`“freeze” (solidify) as it fills an injection-molding mold
`cavity. Thefrozen layer can easily vary in thickness as the
`moldfills, producing differentfrictional shear forces. As a
`result, flow (filling) and solidification (thermoplastic cool-
`ing) should be evaluated together. See freeze-off.
`mold-cavity grit blasting Blowing steel grit or sand
`onto the cavity wall to produce a roughsurface. This sur-
`face treatment may be required to permit air to leave the
`mold during moldingor to provide a desired surface finish
`on thepart. See cleaning, abrasion.
`mold-cavity hobbing Forming single or multiple
`
`moldcavities by forcing a hob intoa relatively s
`blank. Hobbingis a technique where a master n
`hardenedsteel is used to sink the shape ofthe cay
`a heated mild steel, such as beryllium copper. Th
`larger than thefinished plastic molded part becai
`hobbing, the metal shrinks during cooling. See ¢
`erosive cutting and sinking.
`mold-cavity honing Using a fine-grained wl
`or equivalent to obtain precise accuracy of the
`finish.
`mold cavity, injection The two halves oftk
`have a flat parting line. When the two halves me
`halfis literally making contact by one flat surface
`anotherflat surface. Pressure on the injected mel
`cavity is through theplasticator’s pressure-ram ac
`the melt. See clamping; mold cavity, compr
`molding pressure required.

`mold cavity, male The extended half of am
`is designed to match the female half. Also called
`See mold-cavity filling.
`mold-cavity melt-flow analysis A compre
`understanding of the moldfilling process, Detaile
`mation is generated concerning the influence oi
`filling conditions on the distribution flow patter

`sures. From these data, conclusions regarding e.
`tolerances as well as part quality strength, appearar

`stress can be anticipated. Onthis analysis, the best a:
