TECHNICAL REPORT

Good news to those in charge of development of automobile interiors where high quality is required !

Realization of High Quality/High Definition printing and high molding properties.

High Definition Ink System for Molding

We will introduce the compatibility of solid printing with fine printing, beautiful gradation, and uniformity and excellent molding function realized by High Definition Ink System for molding.

Realization of High Quality/High Definition printing and high molding properties. Realization of High Quality/High Definition printing and high molding properties.

1. Decoration method for molded component

Film Insert Molding (FIM/IMD) realize free design for three-dimensional object.

FIM/IMD decorates in three steps, (1) Printing process, (2) Forming process and (3) Injection process. Decoration by these three processes makes it possible to design with high degree of freedom unlike painting etc. due to decoration by printing.

FIM/IMD processes

 

(1) Screen Printing Process:
Decorative printing on thermoplastics resin film.

(2) Forming Process:
Heat and soften preliminarily extruded molding sheet, set to mold before cooling and solidification, trimmed (finishing) after forming to final shape with vacuum pressure or compressed air.

(3) Injection Process:
Insert it into a predetermined mold, heated, molten and fluidized molding resin material into a mold by applying pressure, and solidify by cooling to integrate the printing sheet and molding resin material.

In addition to FIM / IMD, there is a method without injection process but (1) printing and (2) forming process. Even in this case, decoration with high degree of freedom is possible due to decoration by printing.

2. Realization of High Quality/High Definition decorations on molded articles by High Definition Ink System

Realize both High Quality/High Definition Printing and molding property.

Decorating method by printing and molding such as FIM / IMD has always been expected to realize the intended design with high precision because design freedom is very high.

To meet the requirement for such high precision, High-Definition Ink System for molding have responded by combining high-quality and high-definition printing with excellent molding functions. With the compatibility of these two functions, it became possible to realize high precision decorations on molded products such as gradation with dots of 100 µm level, fine lines with width of 100 µm level, beautiful solids without unevenness, etc.

 

Below is an example of forming a film printed with fine lines with different thicknesses of 100 µm level. No wire disconnection or the like is seen after molding, maintaining a beautiful lattice pattern while maintaining the initial thickness difference.

3. Example of superior molding property of High Definition Ink System

Realization of High Quality/High Definition gradation and molding

We maintain a texture that achieves a gradation with a dot diameter of 100 µm even after molding.

 a gradation with a dot diameter of 100 µm even after molding.

It is compatible with vivid, fine-grained gradation and molding. Extend the range of design further.

 vivid, fine-grained gradation and molding.

A case of a large molded product in which a solid and a gradation are printed in one stencil.

In the past, it was necessary to separate plates with solid and gradation, but High Definition Ink System can be printed in one stencil.
