Unclear detail replication in PP/TPO '2079851475616104458
Fenómeno do problema
PP/TPO vacuum-formed parts have fleshy rounded corners, and surface texture or logo replication is unclear, with poor three-dimensionality.
Análise das causas
Insufficient vacuum or blocked/unreasonably distributed vacuum holes prevent the sheet from fully conforming to the mold surface; low sheet temperature and excessive forming speed also make detail replication insufficient.
Solução
①Clean and reasonably add vacuum holes, and check whether the vacuum system leaks; ②appropriately increase the sheet temperature (not excessively); ③switch to pressure forming when necessary or strengthen vacuum in detail areas; ④slow the forming speed to let the material fully conform to the mold; ⑤check the venting of the mold texture area.
Conclusão principal
Detail replication in '2079851475616104458 depends on 'vacuum in place + sufficient temperature + slow speed': for unclear details, first check whether the vacuum system truly establishes sufficient pressure differential, then supplement temperature; texture areas often also require separate consideration of venting.
