Project time: 2014 – 2017
Budget: 8 228 000 SEK
To develop sustainable manufacturing systems it is important to consider a lot of different parameters, e.g. effects on the environment, energy consumption, flexibility, accessibility, degree of rejection, etc. For sustainable manufacturing of automotive components, injection moulding can be an interesting manufacturing technique. The reason is that injection moulding enables fast and cost efficient manufacturing with low energy consumption and large degree of flexibility. Interior automotive components have for long time been manufactured by injection moulding. A problem with injection moulding of interior components is, however, problems to obtain components with even texture and low gloss. The knowledge is good about reasons for surface defects, such as sink marks, blisters and silver streaks, but not so good about the underlying reasons for ghost marks, uneven gloss, and tiger stripes. The objective of the project presented in this report was therefore to improve the knowledge about robust injection moulding of automotive components with desired texture, gloss and color. The aims of the project were:
20% shorter lead times for development of injection moulded automotive components
30% shorter time for start-up of manufacturing of new components
50% less rejection in start-up of manufacturing of new components
4 journal/conference papers
The aims regarding shorter lead times and less rejection are too early to evaluate. The results generated within the project must first we implemented. However, the aim regarding publication of 4 journal/conference papers is fulfilled, see chapter 7.2. The project has for sure improved the knowledge about robust manufacturing of automotive components with desired surface properties and in the following some of the results are briefly presented. Shorter lead time for development of injection moulded automotive components The project has improved the knowledge about parameters that controls the esthetic and haptic properties of injection moulded components. In March 2017 results from the project were presented at FFI Fordonsstrategisk Forskning och Innovation | www.vinnova.se/ffi 4 two seminars. The first seminar, held at Volvo Car Corporation, attracted more than 60 participants from Volvo CC, Volvo TC, IAC Group, Plastal, and others. The second seminar, held at K.D. Feddersen Norden, attracted also more than 60 participants from a large number of different companies (e.g. Scania, Thule and Husqvarna). The new demo mould, which has been developed within the project, will be of great help to reduce the lead times when new components are being developed, since the demo mould enables investigation and determination of textures and materials suitable for different components (size, complexity, texture, …). Efficient and relevant requirements An investigation of the aesthetic properties of injection moulded plates with different textures, carried out by Halmstad University and Jönköping University, have generated a lot of interesting (and unexpected) results. The results will be put together and spread/transferred to designers at the
automotive companies in Sweden. However, a lot of work remains before trustworthy guidelines for robust design and manufacture of injection moulded components with even texture and low gloss are available. Improved knowledge about aesthetic and haptic properties Halmstad University and the Technical Research Institute of Sweden (SP) have carried out a number of different tests and generated a lot of interesting results about aesthetic and haptic properties of injection moulded components. Virtual tools for prediction of esthetic and haptic properties Halmstad University and Jönköping University have developed a tool for prediction and specification of textured surfaces. They have also developed design manuals and a digital library with 3D measured and digitally characterized reference surfaces. Based on the results obtained it is clear that is can be difficult to examine and compare different textures. Technique to measure and characterize texture A large number of plates with different textures have been analyzed and characterized by interferometry at Halmstad University and a digital library with 3D scanned surfaces have been generated. The use of interferometry (e.g. GFM MikroCAD 3D) has proven to be very efficient in
characterizing textures. Knowledge about different processing parameters The processing windows for three different plastic materials (PP, ABS and PC/PBT) have been tested and analyzed by the use of the demo mould and the results are at the moment evaluated at Volvo Car Group. However, more tests will be carried out in the future to improve the knowledge about robust injection moulding of automotive components with desired surface properties. Shorter start-up times for new components The new demo mould will facilitate determination of suitable materials and textures for different components. The demo mould will also facilitate determination of suitable processing windows and thereby reduce start up times for new components. Demo mould for test and development of new materials and new textures An important result from the project is the demo mould which has been designed and manufactured as a part of the project. The demo mould contains a large number of processing difficulties and is equipped with temperature and pressure sensors. The demo mould has been ested and evaluated at five different occasions and shown to work satisfactorily. After the project the mould will be placed at IAC in Färgelanda.
