【Online Open Week】”Soft-touch Polyurethane + Injection Molding” One-step Approach for Prefect Surface

2020-08-31

Abstract:

Besides rich color-textures on the surface, touching is also an important factor for fancy design automotive interior. The common Polyurethane material not only features with gorgeous high-gloss and self-repairing but also can adjust itself flexibility, which is widely used in premium automotive interior coating. However, different technologies will cause different design flexibility, effects, and costs when using the same material.

ReactPro IntegratedSolution of Polyurethane and Injection Molding is jointly developed by YIZUMIand FRIMO Germany, it will bring more possibilities for the popularization of premiumand multifunctional surfaces such as automotive interiors, 3C and homeappliances in a more innovative and economical way.

How ReactPro Works

YIZUMI ReactPro is a combined technology. It combines polyurethane RIM（Reaction Injection Molding）with the injection molding process. Polyurethane coating is applied to the surface of injection molding product in a closed mold. Compared with traditional PU surface spray coating process, ReactPro could achieve high-quality surface in only one step, with less procedure but high efficiency, substantially reducing production cost.

Traditional interior production Processes

YIZUMI adopts InPUR “1+2” mould technology jointly developed with GK Concept Germany to realize more economical and efficient multi-component injection molding. Two PU moulds are directly placed next to the thermoplastic mould. The injection-moulded thermoplastic carrier is then transferred by a robot into one of the PU moulds to carry out PU injection molding. PU moulds operate alternately during every cycle. Compared with the horizontal and vertical rotary table in traditional way, InPUR “1+2” mould technology works without a swivel unit. Therefore, the design is more compact, the cycle time of batch production can be greatly saved as well.

Soft-touch Polyurethane and Injection Molding One-step Approach for Prefect Surface

During the YIZUMI Online Open Week, YIZUMI ReactPro will further display one-step-molding “Soft-touch Polyurethane + injection molding” by producing engine cover with polyurethane surface on site. Various surface effects including soft-touching, self-repair, high-gloss surface, matte effect, 3D depth are available. In regard of polyurethane that widely used in automotive industry, YIZUMI ReactPro solution makes more changes for design: products can be transparent, can be colorful, even if there are scratches on the surface, they will disappear in few hours at room temperature.

Additive manufacturing will be seamlessly integrated in the manufacturing process. SpaceA Industrial Pellet 3D Printing will print a TPU seal ring on the engine cover back. Meeting the needs of large-scale production and personalized customization of enterprises at the same time.
