Combina ti on Technology As already men ti oned in the intro- duction of this article, the look and feel of plastic parts plays a tremen- dous role in our business. Especially in foam injec ti on moulding long ti me only the rapid hea ti ng cooling method guaran ti es shiny surface quality – but with the disadvantage of higher invest- ment cost and longer cycle ti me during produc ti on. The simple ceramic coat- ing of the tool cavity walls brought the breakthrough. The Combina ti on Technology or Inte- gra ti ve Technology o ff ers a wide variety of methods to improve the look and feel of fi nal plas ti c parts. The idea of combina ti on technology is developed by a cross-technology poten ti al analy- sis of the known industry processes. The material and process combina ti ons emerged as a result form an important cornerstone for Yizumi’s research ac- ti vi ti es in the headquarters in China as well as in the R&D Pre-development Centre in Aachen, Germany. One of the fi rst ac ti vi ti es was the development of the so called ‘React- Pro’ process: Based on an exclusive agreement with the company Frimo Lotte / Germany we developed the process of over fl ooding a thermoplas- ti c carrier part by PU coa ti ng. To ex- plain the React Pro machine system in a simple manner we can say that our engineers married their DP 2-platen injec ti on moulding standard machine with the PU equipment produced by Frimo. The Yizumi ‘smart and be tt er’ approach is given by this technology by an innova ti ve tool concept we de- veloped together with our network partner GK Concept from Dresden / Germany. Based on the ReactPro process you can produce fi nal plas- tic parts with high glossy surfaces and also with soft touch surface if requested. A second example to get a better ‘look and feel’ was developed as ‘DecoPro’ process and presented already at Chinaplas 2018. In this case an aluminium foil was back injected by a thermo- plas ti c carrier. The fi nal part was an engine cover as dem- onstrator. The tool design integrated the cu tti ng of the Al foil whereby the foil was con ti nuously delivered from a roll. DecoPro in this case delivered a fi nal part with a look and feel like pure metal! Plas ti cs Industry 4.0 The trend word ‘Industry 4.0’ is in every mouth! On one hand it is a ma tt er of accessing a high amount of di ff erent data, provided by material supplier as well as machines and sen- sors inside the whole supply chain. On the other hand, the focus is a stan- dardised analysis and utilisation of this data for new business models. Yi- zumi is prepared to a tt end to this new world and o ff ers all interfaces which are standardised by Euromap. One typical example for the use in the Industry 4.0 world is our new develop- ment called DCIM (Direct Compounding Injec ti onMoulding): DCIM is a complex SpaceA, on the left Nicolai Lammert (Head of Additive Manufacturing), right Richard Yan (CEO Yizumi) Engine cover with thermoplastic carrier and second component flooded PU after first trial
