RHCM高光无痕注塑技术目前在国内尚属于一项先进的生产工艺。由于这一技术大大改善了制品的表面质量和表面强度，并可取消后续的喷涂或喷漆等工艺、既保护了环境和操作人员的人身健康，又因减少工艺流程，省去了昂贵的二次加工费用，在大幅度降低生产成本的同时，节省能源与材料。随着塑料件的应用日趋广泛，以及人们对于环保，安全的意识逐渐增高，高光无痕注塑技术必将成为未来注塑技术领域的又一颗灿烂新星。
RHCM高光无痕注塑成型技术 VS 传统注塑成型工艺
RHCM高光无痕注塑成型技术与传统注塑成型工艺相比之下，能大大改善产品表面光泽度，解决产品表面熔接痕问题，并对提升产品表面硬度也有一定帮助. 另外，RHCM高光无痕注塑成型技术也可以应用到添加纤维的工程塑料中，能够有效解决产品表面浮纤的问题。6 o9 Q3 j) f# F2 h$ RHCM是如何消除产品表面熔接痕1
熔接痕的形成是由两股或以上的融熔塑料在射出成型的填充过程中，融熔塑料流的波形前端在模腔中相遇会合，如果模腔表面温度不足或流体遇合压力不足，便会造成合流端无法完全熔合，形成产品表面出现熔接痕缺陷；另外，如塑料中含有添加物(例如: 色母)，在熔合位置更会出现较为明显的颜色差异。然而，运用RHCM高光无痕注塑技术，让我们可以在每次开始进行射出成型过程之前，把模腔表面温度快速提升至树脂塑料的热变形温度以上(HDT)，从而大大增加融熔塑料在模腔内的流动性，减低融熔塑料与模腔表面之间的磨擦阻力，显著地消除传统注塑工艺产品表面的熔接痕问题。除此之外，RHCM高光无痕注塑技术配合特殊工程塑料更可生产出无痕高光泽度的树脂产品，省却产品因表面外观要求，而进行的二次加工 (例如: 喷漆.UV…..).
RHCM specular non-mark injection technology at present in China is still belongs to an advanced production technology. Because of this technology has greatly improved the product's surface quality and surface strength, and may cancel the follow-up of spray or spray paint for technology, has protected the environment and operator's personal health, and because reducing process saves the expensive second processing cost greatly reduce the production cost, in the meanwhile, save energy and material. With the application of plastic parts, as well as people increasingly wide for environment protection, safety consciousness gradually heighten, specular non-mark injection technology will become the future injection technology, and a single bright star. RHCM specular non-mark injection molding technology VS traditional injection molding process RHCM specular non-mark injection molding technology and traditional injection molding process, by contrast, can greatly improve the product's surface gloss, solve product surface weld 1ine problems, and to upgrade the product surface hardness also have certain help. In addition, RHCM specular non-mark injection molding technology can also be applied to add fibre engineering plastic, can effectively solve product surface floating fiber problem. 6 o9 percentile j) f # F2 h RHCM is $how to eliminate the product surface weld 1ine 1 Weld 1ine is formed by two strands or above with melting plastic injection molding, fill in the process of molten plastic flow, integrates the waveform in cavity to meet in front, if meet cavity surface temperature or inadequate fluid YuGe insufficient pressure, can cause confluent end cannot completely fusion, form product surface appear weld 1ine defects, In addition, such as plastic in contain additives (e.g., masterbatch), can appear in fusion position more obvious color difference. However, using RHCM specular non-mark injection technology, let us can begin in each injection molding process before cavity surface temperature rapid ascent to resin plastic heat distortion temperature above (HDT), thereby greatly increasing melts in molten plastic mold cavity liquidity, reduce molten plastic and harmony between cavity surface friction resistance, significantly eliminate traditional injection molding process product surface of weld 1ine problem. In addition, RHCM specular non-mark injection technology with special engineering plastics can also produce non-mark high gloss resin products, dispense products by the surface appearance requirements, but the second processing (for example: painting UV...). .
