IMD technology
IMD (In-Mold Decoration
,or Film Insert Molding) technology uses Decorated (Screen Printed), 3-D Formed, and Trimmed film material as the thin shell,then plastic is inserted into the back side of this thin shell by injection molding process to make the decorated components.
By this special process, it is very easy to make plastic components with complex curve, 3-dimentional shape with registered symbols, multi-colored decorations,as well as the light-transmitting design.IMD process can take over many post-molding operations like heat-transter printing, screen printing,spray painting,laser-etching or electro-plating on the plastic injected components thus to save a lot of production cost.
It also gives unlimited decoration possibilities with precisely registered graphics on the plastic components.Back-side printing decoration application makes IMD products scratch and chemical resistant to achieve the long lasting finishes.

The advantages of high pressure pneumatic forming process:
1. Low residual stress on the 3-D formed plastic film
2. No direct tool contact to the front film surface thus no scratch damage.
3. Excellent registration and forming accuracy.
4. Short cycle time
5. It allows fast tool setup and changeover.
6.Low tool making cost.

Principle of High Pressure Forming:
E
qual pressure with in the mould, will not caused the stress problem by sharp angle or tearing of the film.
High positioning accuracy, plastic sheet will not be part of the stretched.
Forming temperature is below T.G temperature, plastic sheet will be formed more easily.
