Resin harenae processus, harenae core tarde harenae core et non sunt boni suci, defectus defectus ad mittentem harenae core. Quam ut eliminate eos?

In resina harenae processus, cum usura iactaret harenae cors, et mittens exhibet "succulent" defectus ad core positio. Quid est hoc defectum?

I, fieri potest factors debitum ad defectus

I. Deformatio aut obsessio harenae core: insufficiens vires harenae core: De viribus iactaret harenae core est inferior quam postulationem. Rationes potest includit: improprium curando processus: humilis calefacere temperatus, insufficiens calefactio tempus, aut inaequalis calefacit, unde in incompleta solidificatione harenae core et humilis. Quality exitibus cum laminated harenae: pauper qualis est rudis harenae, humilis resin contentus, pauperes resinae qualis (ut humilis scelerisque viribus), inaequaliter, et pre curatio propter prolongati repono tempore, ut ad repono tempore ad tempus, et pre est ad repono in tempore ad extinguetur, et pre curatio propter longum et resin). Arena Core Design Exitus: Arena core est quoque tenui, tenuis-muratas, aut structuram universa et sua firmitas rigor est insufficiens. Caput Core Gap / Positioning proventus: Nimis Core Caput Gap: De harenae core solutam in core sede, et proni et effundens processus. In gap inter core capitibus est parva: cum inserere core vel claudendo arca archa, quod est fortiter inserta, causing loci deformatio vel fractura de harenae core propter compressionem. Positioning ACUS / sulcus amplitudo deviation et gerunt: et harenae core non potest accurate posita vel quatit per operationem. Improprium Core remotionem operationem: Per Core remotionem processus, bumps aut improprium operationem potest facere damnum vel levi deformatio harenae core. Improprium arca claudendo operationem: nimia pressura et instabilis operationem durante arca claudendo potest facere partiales vel altiore obsessio, deformatio, aut etiam fractio Metal Liquid Impact: Dum infundens, summus celeritas metallum liquidum fluxus protinus confligant infirma partes harenae core (ut core capite vel cantilever part), ut ad flectere, deformare, aut ex parte confringat, deformare, aut ex parte et cadunt. Systematia ratio infundens (ut direct harenae core) et exacerbate hoc problema. Lifting the box (running fire): After pouring, if the clamping force of the upper and lower molds is insufficient (loose or insufficient force of the pressure iron/fixture), or the static pressure of the metal liquid is too high, it may cause the upper mold to be lifted (lifting the box, running fire). Tum harenae core alloquatur vel moveri totum inde crescente in magnitudine mittentem vel aspectus succulents. Quamvis mutatio tota cavum, characteres harenae core positio magis pronuntiata.

II. Thermal Expansion harenae cors (a unique forsit de lawolanto harenae): "Crusta effectus" expansion: hoc est a significant propria tunicas harenae cors. Cum summus temperatus metallum liquida contactus superficies harenae core et superficies harenae cito calefacit et solidatur (formatam durum "crusta tardius et continues ad expand. Hoc durum testa impedit internum expansion, causando internum expansion vi ut dimisit exterius. This may result in the outward compression of the molding sand: if the molding sand (resin sand) around the sand core has sufficient strength and poor yielding (resin sand has high strength at room temperature but some thermoplasticity at high temperature), the expansion of the sand core will compress towards the direction of the casting cavity, causing the cavity size to decrease. Sed in speciei condicionibus (ut inaequaliter pomiferum, complexu structuram, et loci impediendas), ut etiam manifestum est ut distortio vel loci tumidam harenae core se, indirecte ducens ad succulentum castings. Squeezing castings inward (mainstream explanation): When the sand core is completely surrounded by molten metal, the expansion force of the core will squeeze the metal melt pool that has not yet fully solidified towards the center, causing the shrinkage of the casting cavity to be obstructed and the casting size to develop towards a "bulging" direction (the cavity size becomes smaller). Hoc prorsus oppositum succulents. Extreme expansion leading to cracking or displacement (which may result in succulent): If the sand core expands too much or is severely obstructed, internal stress may cause the sand core to crack, or gaps may form at the joint between the sand core and the mold wall (causing burrs), or unpredictable overall deformation may occur under specific constraints, all of which may lead to abnormal changes in casting wall thickness or succulent protrusions. Nimia effusione temperatus: nimia effusione temperatus exacerbates ad scelerisque expansion phaenomenon de harenae core. Influence of refrigerationem processus post metallum solidat et extenuetur, harenae core collapsa. Si harenae core expands et cecidit male vel inaequaliter in refrigerationem processus, ut etiam afficit ad ultima figura de mittentem.

3. Foreign objects or locally high compactness in the cavity: scattered sand core blocks or debris: during the core insertion process, the sand core blocks or fractures locally, or scattered sand or debris falls into the cavity before closing the box, ultimately occupying the cavity space and being wrapped by metal, forming succulents. Coating cumulus vel detonment: loci coating cumulus super harenae core vel cavum est densissima vel cadit in inaequalis, occupantem spatio et formando succulents. Upeven Compaction de CUMATIUM harenae: in CUMATIUM, est nimia compaction in quibusdam locis (quamvis resin harenae formatae per hardening, arena vel metallum pressura, causing in area in calidum vel metallum, ut et extrustione in cavum ad calorem, et ad excessum exitum, ut ex extrusionem cavitatis, consequens in excessus expansion in casu in calidum et in modum succulents.

II, quam ad Troubleshoot et propono:

I. Observa locum et ERREPTICUS defectuum: est boni suciCulent iusto (adventum in eodem loco omni tempore) vel temere? The shape of succulent protrusions (are they regular protrusions, burrs, or irregular bulges?)

II. Reprehendo in harenae core: Size mensurae: Focus in mensuræ clavis dimensiones (praesertim ecclesiam dimensiones) de harenae core post solidificationem et core extraction, et conferas in speculativo et core fingunt. Reprehendo pro aliqua signa deformatio vel occursum. Visual inspectionem: Reprehendo superficies rimas, soluta, et chipping. Fractura test vires (est centrum CALAMISTRATUS?). Traceability curationis processus reprehendo temperatus curvas, temperies uniformitatem et velit tempus pistoria clibano clibano ut occurreret requisitis harenae harenae core murum crassitudine.

III. Reprehendo core caput et core possessor: mensura magnitudine core caput core arca et magnitudinem Core possessor inferioris exemplar et reprehendo an gap est rationabile et consistent. Reprehendo in magnitudine et gere de positioning pin / sulcus.

IV. Reprehendo in operationem processus: observe utrum core et arca claudendo operationes sunt standardized et firmum? Est ulla collisione vel durum expressa phaenomenon? Reprehendo si pondus et in pressionem ferrum / fixture satis et certa? Est infundens processus lenis? Est Floratus metallum fluit directe in harenae core?

V. Reprehendo Material and Processus parametri: Books iactaret harenae: reprehendo batch, repono tempore, et utrum sint ulla humidum massas? Si necessarium, experiri calidum vires et tensile vires. Fundens Temperature: Est etiam princeps? Conatus ad redigendum appropriately (fretus in materia) dum ensuring Liquidity. Arena Core Design, aestimare num magnitudinem Core caput, harenae consummatio, et supplemento dispositio sunt rationabile? Have vos considerari scelerisque expansion characteres de iactaret harenae? Proventus processus subsidia (anti deformatio moles) in key areas. Fundens ratio: ne aligning ad sprue directe cum infirma areas de harenae core. Exhaurit: curare lenis exhaurit de harenae core ad vitare Gas blockage ut causam loci metallum liquidum pressura esse nimis altum et ventilabis in harenae core.

VI. Simulation Analysis, cum condiciones permit, utor mittens simulatio software ad analyze ad impletionem et solidificationis processus de fishlen metallum, observe deformatio, obsessio, et accentus in arenibus core.

Summary of Key Points: Quod Prima Suspicatus Factor enim Succulentales defectus per iactaret harenae cors est deformatio vel displacement de harenae cors in vestibulum, operatio (core insertionem / arca claudendo) et effusione. Satis viribus, Core Gap exitibus, operational collisionibus, metallum liquidum impulsum, et arca elevatio per pauperes solidificatione (sub ardenti) sunt directe et communia causas. De unique scelerisque expansion problema de laminated harenae potest ducere ad insufficiens DECREMENTUM de interiore cavum (augmentum in castra crassitudine aut decrementum in interiore caxe), sed in extrema vel impetrae et directe, ut succulent. Systematice investigandis deformatio / displacement factores (vires, alvi, operatio, elevatio) solet solvendo problems solvit.
