Hunter S. Thompson once said, “Anything worth doing, is worth doing right.” It’s an excellent credo to live life by, but it also applies to product design.
One manufacturing process, in particular, that requires expertise and attention to detail is in-mold decorating (IMD). When done correctly, IMD can yield impressive results. But if certain considerations aren’t followed, the outcome may not be what you expected.
What is in-mold decorating?
The process of in-mold decorating (IMD), a type of film insert molding, involves inserting a printed film in an injection mold before it is filled with plastic. Compared to traditional methods of product decorating or labeling, IMD is often more efficient and cost-effective. It is used in a wide range of industries, including automotive, home appliances, medical devices, automotive, sports equipment, and consumer electronics.
IMD offers many design and manufacturing benefits, including:
- Product differentiation with attractive colors and graphic effects
- Decoration of 3D parts
- Quick change-over of graphics using the same injection tool
- Eliminated secondary labeling
- Reduced application labor
- Enhanced durability with chemical and abrasion resistance
- Permanently embedded graphics
- Enhanced design flexibility and inventory management
- Ability to create in-mold electronics
Considerations When Using In-Mold Decorating
There are multiple forms of IMD such as flat film, formed film, first surface graphics, and second surface graphics. Due to the complexities of material selection and manufacturing, it is advantageous to work with a partner who has a proven track record with IMD.
To achieve the best results with IMD for your product, the following considerations should be made:
- Film and thickness – in general, polycarbonate film (coated or uncoated) offers the greatest range of performance characteristics; a minimum film thickness of 0.007 mm to 0.025 mm is suggested
- Surface to decorate – resins must be selected for their mold geometry and flow characteristics
- Product design with molding in mind – including draft angles and thermoforming size limitations
- Forming requirements – such as injection method, gating, and graphic placement
- OEM performance requirements in the design
- Testing to ensure the combination of films, inks, adhesion promoters, laminates, and resins will work together to create a cohesive part
