Mokhoa oa moralo oa hlobo

Tlhahlobo ea hlobo e entsoeng ka ho hloekisa e akarelletsa boholo ba betch, lisebelisoa tsa ho bōpa, maemo a nepahetseng, moralo oa geometri, botsitso ba dimension le boleng ba holim'a metsi.

1. Boima ba batch bo sebelisetsoa liteko. Ha sehlahisoa sa hlobo se nyenyane, se ka etsoa ka lehong kapa resin. Leha ho le joalo, haeba hlobo ea liteko e sebelisetsoa ho fumana boitsebiso bo fokolang, botsitso bo boholo, le nako ea potoloho ea sehlahisoa, hlobo e le 'ngoe e lokela ho sebelisoa bakeng sa teko' me e ka sebelisoa tlasa maemo a tlhahiso. Ka tloaelo lipeipi li entsoe ka gypsum, koporo, aluminium kapa allium-steel alloys, 'me li-aluminium-resin ha li sebelisoe hangata.

2, geometric shape design, design, often have to consider the dimensional stability and surface quality. For example, product design and dimensional stability require the use of a female mold (female mold), but the surface requires a higher gloss product, but requires the use of a male mold (protrusion), so that the plastic parts ordering party will consider these two Point so that the product can be produced under optimal conditions. Experience has shown that designs that do not meet actual processing conditions often fail.

3, boholo bo tsitsitse, ha ho ntse ho etsoa, ​​karolo ea karolo ea polasetiki ha e kopana le hlobo e molemo ho feta ho tiea ha karolo ea karolo e tlohang hlobo. Haeba boima ba lintho tse bonahalang bo hlokeha nakong e tlang ka lebaka la boima ba lintho tse bonahalang, ho ka etsa hore ho fetoleloe ha hlobo ea banna ho hlobo ea basali. Ho mamellana ha dimension ea karolo ea polasetiki e ke ke ea e-ba tlase ho 10% ea tekanyo ea shrinkage.

4. Karolo ea karolo ea polastiki. Mabapi le sebaka seo ho sona ho ka kenyelletsoang boitsebiso boo, mohaho o ka holim'a karolo ea ponahalo ea karolo ea polasetiki e lokela ho thehoa ha o kopana le hlobo. Haeba ho khoneha, karolo e hloekileng ea karolo ea polasetiki ha ea lokela ho kopana le hlobo. Ho tšoana le ho sebelisa hlobo ea basali e le hore u etse sekepe le seaparo sa ho hlatsoetsa liaparo.

5, ho fetoloa, haeba u sebelisa sesebelisoa se nang le maiketsetso ho tlosa bohale ba likarolo tsa polasetiki, ka bophara, bonyane ho 6 ~ 8mm lekaleng. Mosebetsi o mong oa ho qetela, o kang ho sila, ho laola laser kapa jetting, o tlameha hape ho tloha margin. Lekhalo pakeng tsa mela e methapo ea thipa e shoa ka ho fetisisa, 'me bophara ba ho aroloa ha ho bolaoa ho otloa hape ke ntho e nyenyane, e lokelang ho tsejoa.

6, shrinkage and deformation, plastic shrinkage (such as PE), some plastic parts are easy to deform, no matter how to prevent, plastic parts will be deformed during the cooling phase. Under this condition, the shape of the forming mold is changed to accommodate the geometrical deviation of the plastic part. For example, although the wall of the plastic part is kept straight, the center of the reference has deviated by 10 mm; the base of the mold can be raised to adjust the amount of shrinkage of this deformation.

7. Palo ea shrinkage e lokela ho nkoa e le ho etsa liforomo tsa polasetiki. 1 Sehlahisoa se bōpehileng se fokotseha. Haeba shrinkage ea polasetiki e sa tsejoe ka ho hlaka, e lokela ho ba sampuli kapa e hlahlojoe ke hlobo e tšoanang le eona. Tlhokomeliso: Ke shrinkage feela e ka fumanoang ka mokhoa ona, 'me boholo bo holofetseng bo ke ke ba fumanoa. 2 Shrinkage e bakoang ke liphello tse bohloko tsa sekhahla se hare, tse kang diereiti, silicone rabara, joalo-joalo 3 Shrinkage ea lintho tse sebelisoang ka sebōpeho, tse kang shrinkage ha ho etsoa aluminium.
