Trash Can Production Process Nhwehwɛmu
Sɛ́ ade titiriw a ɛwɔ nkurow akɛse mu ahotew ho nhyehyɛe mu no, nwura kotoku a wɔyɛ no nya sɛnea ade no kyɛ, sɛnea ɛyɛ fɛ, ne sɛnea nneɛma a atwa yɛn ho ahyia no yɛ adwuma no so nkɛntɛnso tẽẽ. Nnɛyi nwura kotoku a wɔyɛ no fa anammɔn atitiriw anan ho titiriw: nneɛma a wɔde yɛ nneɛma a wɔde yɛ nneɛma, nea wɔde injection nwene, nea wɔde yɛ nwura no ani, ne nea wɔboaboa ano na wɔsɔ hwɛ.
Raw material ahosiesie fã no hwehwɛ sɛ wɔhwehwɛ nneɛma a wɔde yɛ adwuma no mu denneennen. Nkurow akɛse mu nwura kotoku taa de plastic a ɛko tia wim tebea-te sɛ polyethylene a ɛyɛ den-density polyethylene (HDPE) anaa polypropylene (PP) na edi dwuma. Wɔde masterbatch ne nneɛma a wɔasan de adi dwuma (ɛnyɛ nea ɛboro 30%) frafra sɛnea ɛfata denam automated metering system so de hwɛ hu sɛ nneɛma no mu yɛ den na ɛne GB/T 28019-2020 gyinapɛn ahorow a ɛfa nneɛma a atwa yɛn ho ahyia ho banbɔ ho no hyia. Industrial-grade nwura kotokuo nso betumi de nnuru a ɛmma ogya ntumi nhye anaa nneɛma a ɛko tia nwura bɛka ho.
Injection molding yɛ adeyɛ titiriw. Bere a wɔabɔ no wɔ 200-280℃akyi no, wɔde nneɛma a wɔde yɛ no gu nkuku a ɛyɛ pɛpɛɛpɛ mu denam afiri a wɔde twitwiw nneɛma mu a wɔde nhyɛso a ɛyɛ 15-25 MPa so. Onwini kyinhyia no di bɛyɛ sikani 30-90 (egyina nneɛma dodow so). Wɔhwɛ nkuku mu hyew so wɔ digrii 40-60 ntam na ama asɛe no ayɛ ketewaa bi. Nwura kotoku akɛse hia nkuku a ɛwɔ abura pii anaasɛ mfiridwuma a wɔde yɛ nwura a wɔde gas boa na ama wɔatumi ayɛ no yiye.
Nea ɛka ayaresa a wɔde yɛ nneɛma a ɛwɔ soro no ho ne tintim ne petepete. Wɔde UV offset tintim na ɛtintim nsɛm ne nhwɛsoɔ na ama wɔanya UV-fading resistance. Wɔtaa de anyinam ahoɔden powder-kata abɔnten nwura kotoku so, na nea wɔde kata so no mu duru yɛ 80-120μm. Curing wɔ 180℃nya wear resistance ne anti-sticking su. Wɔde dade a ɛnyɛ den na ɛyɛ nneɛma bi a ɛyɛ fɛ na ɛhwehwɛ sɛ wɔyɛ no fɛfɛɛfɛ anaasɛ wɔde brush.
The final stage is assembly testing. Trash cans with inner containers require rubber sealing rings to be installed. The entire product must pass load tests (≥50kg static pressure), drop tests (1.5m height), and dimensional accuracy measurements (tolerance ±1.5mm). Qualified products are disinfected with ozone before packaging and labeled with material symbols according to international standards (such as a recycling symbol >7).
Adeyɛ no nyinaa betumi amia bere a wɔde yɛ ade biako-ade no ma ennu simma 2 denam afiri a wɔde yɛ nneɛma no so. Bere koro no ara mu no, ɛde ne ho to MES nhyehyɛe no so sɛ ebenya nhyehyɛe no mu yiyedi a edi mũ-ayɛ, ahwɛ ahu sɛ nwura kotoku no bɛkɔ so ayɛ adwuma mfe 5-8 wɔ mmeae a ɛyɛ den.
