FAQ

What is the meaning of FIM/IMD?

The abbreviations, FIM and IMD, stand for Film Insert Molding and In-Mold Decoration. For these methods, the printed film is set into the mold and molded with molding resin as the finished product.

We recommend reading the FIM/IMD technology White Paper:
(1) FIM/IMD – 3 Process stages & Benefits
(2) FIM/IMD – Screen printing process –
(3) FIM/IMD – Forming process –
(Final) FIM/IMD – Injection process –

We recommend reading the following reports:

Using FIM/IMD method, can you give us some examples of substrate film and molding resin combinations?

PC, PET, and Acrylic substrate sheets are suitable. Suitable resins are PC, PMMA, PC/ABS, AS, etc. However, PP and Olefin are currently difficult to use because they do not have good adhesiveness to the substrate materials.

What is the difference between Film Insert Molding and In Mold Decoration? Do you use different inks for each?

For the FIM method, the printed surface will be placed between the substrate sheet and the resin. On the other hand, for IMD method, the printed surface will appear on top of the adhered layer of the substrate sheet and the resin. The type ink will depend on the application and your requirements.

What is the largest size that you can use for the Insert Molding Method?

Theoretically, it depends on the capability of molding machine. However, there is an elongation limit of the substrate sheet; it varies depending on the printing materials you are using.

Can you give some examples of the type of industry where a combination of ink and molding method is being used? What would be the actual finished product?

The main industries will be automobile interiors, amusements, and home appliances. Their finished products are such items as speedometers, pinball game machines, water boilers, TVs and possibly as cover material in various other areas.

Do you have any restrictions when you use functional inks for molding inks?

There are some limitations of color hue, glossiness, and other properties. Sometimes, Teikoku Inks is unable to meet a customer’s requirements due to the design of the product.

We found that sometimes when we peel off the print from the injected resin, ink remains on one side or sometimes on both sides. Why does this occur?

In the case of ink remaining on the substrate, adhesion to the injected resin is poor. When ink remains on the injected resin, the adhesion to the substrate is poor. This is delamination. When ink remains on both sides, adhesion to substrate and injected resin are good, but the cohesion of the ink layer is poor. This is a cohesion failure.

The printed layer peeled away from the injected resin. What should we do?

This may be due to a mismatch of ink, substrate and the resin. Please contact our representative.

We have always had good adhesion, but suddenly peeling has occurred. What should we do?

Ink attached so far but it suddenly peeled off. I don’t know what to do.
Please check the following.
(1) Film thickness of printed ink layer
Thinner binder layer tends to have weaker adhesion.
(2) Drying conditions for printed ink layer
If ink doesn’t dry sufficiently, the strength of the printed ink layer becomes weak and cohesive fracture will occur.
(3) Are there any additives such as defoamer contained in ink or binder?
If additive such as defoamer is added in ink, ink’s adhesion to resin tends to be weak.
