V-Process Casting Production Line .
V-process casting production line no yɛ nea wonim no sɛ green casting a ɛwɔ afeha a ɛto so 21 no mu. foundries pii adan V-process casting. V-process casting nhyehyɛe no te sɛ nea edidi so yi:
1. Paw model no na fa nsusuwso a wɔhwehwɛ no to mprɛte a ɛwɔ tokuru so. nhwɛso no wɔ mframa ntokuru pii. wɔ vacuum no nkɛntɛnso ase, saa ntokuru yi betumi ama plastic film no abata nhwɛso no ho denneennen.
2. Film Heating: Fa ɔhyew afiri di dwuma ma ɛnyɛ hyew na fa plastic film a ɛwɔ tensile rate a ɛkorɔn ne plastic deformation rate a ɛkorɔn. ɔhyew no yɛ hyew no mpɛn pii no yɛ 80 ne 120 degrees Celsius.
3. Film Forming: Wɔakata film a ayɛ mmerɛw no so wɔ model. no ani so denam mframa ntokuru so, wɔ vacuum suction force a ɛyɛ 200 kosi 400mmhg ase no, wɔde film no abata model no ani denneennen.
4. Fa anhwea adaka no si hɔ: Fa anhwea adaka soronko a wɔde yɛ v-process casting no gu model a wɔde sini akata so no so.
5. Anhwea a ɛka ho ne compaction: Fa anhwea a ɛyɛ dry a ɛyɛ adwuma yiye a ɛyɛ adwuma yiye ne particle size a ɛyɛ 100 kosi 200 mesh gu anhwea adaka no mu na ɛwosow kakra ma ɛyɛ mmerɛw ma anhwea no yɛ den sen density.
6. Kata nkukuo no so: Bue kuruwa a ɛrehwie gu no, fa anhwea no ani yɛ mmerɛw, na fa plastic film kata anhwea adaka no so ma ɛnkata so.
7. Demolding: Wɔde anhwea adaka no fi hɔ denam film a ɛkata V-process casting sand box no ani so, na afei anwenne no yɛ den denam wim nhyɛso. so bere a wɔrebubu no, vacuum a ɛwɔ nhyɛso adaka no mu no yɛ nea wɔayi no adi, na ɛnam so yi adsorption force a ɛwɔ template no so{3} no yɛ adwuma wɔ film no so{3} no
8. Adaka Nhyiamu ne casting: Ansa na wobetumi de nnaka nhyiamu, core ne chill iron asi hɔ sɛdeɛ process requirements. no, wɔde atifi ne aseɛ nnaka no bom yɛ nkukuo a ɛwɔ apono, risers ne cavities, na afei wɔtow wɔ vacuum tebea mu{2}}
9. Wɔde dadeɛ a ayow a ɛfiri anyinam ahoɔden fononoo no mu no kɔ riser a ɛregu no mu, wɔde anhwea adaka no kɔ shakeout area, castings no gu, na anhwea no hyɛn circulation system no mu.
