Decoform procedure demonstrates its effectiveness in series production

In the decoration of molded parts of large surfaces such as boards of instruments, lateral coverings of door, mats or boot liners, the Decoform procedure developed by Krauss-Maffei offers clear advantages over other methods of manufacture. Decoform series machines are characterized by short cycle and minimum space requirements. The investment is less than the vertical extrusion process. The low pressure injection procedure is easy to automate, allows a flexible production and improve eco-efficiency in modern production.

A completely decorated in a single cycle door can be manufactured with the direct combination of the procedure for stamping and injection molding

Decoform series machines are horizontal injection molding machines, which are equipped with a printing module. This patented procedure, the mold closes first with decoration material. Only during the injection process is placed on the vain of stamping mould. In this way, the molten material adheres to the face of decoration. In addition, the flux material maintains the mass cast in balance and prevents you slipping between two halves of the mold. Then the molten material is stamped on the cavity with a motion for closure of the mold.

With this process there are no visible points of injection on the piece of decoration. Decoform module can be adapted to the series C and MC of Krauss-Maffei. The incorporation of machines with closing forces well below those needed in conventional processes is possible thanks to the minimum internal pressure of the mold.

With this process are still not visible points of injection on the piece of decoration

The automotive industry already applied this procedure in the production series with very good results. Thus, Johnson Controls leads to the dashboard of the SLK model of DaimlerChrysler Decoform system, with shorter cycles and a better quality of the surface than in the extrusion process. Peguform, the production of a dashboard with the Decoform procedure has incorporated from the start of series production. It's a compound blade TPO and polypropylene for the Crossfire of DaimlerChrysler model. At Faurecia they were launched in the first and second quarter of 2003 other production projects in series for the Decoform transformation of TPO sheet with polypropylene, for Volvo and DaimlerChrysler. The advantage of this procedure lies in that it do without forming sheets prior. For years now, in Montaplast are decorated by injection columns with Decoform series machines. Acoustic systems, such as for car mats-based carpet and TPE compounds, are also made with lower costs thanks to the Decoform.Tras the success of the introduction of this procedure, Krauss-Maffei development engineers began to think about expanding the fields of application of the system Decoform. Thus the manufacture of doors in a process of a single (one-shot) phase can be carried out in such a way to run an additional injection process immediately after printing. The aim is to produce a fully decorated door (backsplash and frame) in a single operation of injection, so that you do without unnecessary and subsequent process of Assembly. With the extrusion process, a system of manufacturing such one-shot is not possible.
