In-mould Decoration (IMD) is a versatile and cost effective method of decorating and manufacturing durable plastic parts.
  
Integrate components such as lens, body and keypads into a single component with In Mould Decoration (IMD) formable hard-coated film.  
Ideal for telecoms, appliance and interior automotive applications.
Autotype has a range of innovative Polycarbonate and Polyester film systems suitable for In Mould Decoration (IMD), allowing you to decorate moulded components. This hard coat technology provides enhanced scratch, solvent and chemical resistant surfaces, with systems for altering texture and gloss levels on a part surface. The product systems are suitable for a variety of different depths of form, from flat inserts to complex 3D shapes.
  This In Mould Decoration (IMD) process can best be described as Film Insert Moulding.  
Firstly, the flat film is decorated, the most common method being to reverse Screen print the film, thereby protecting the image. Secondly, the film is optionally formed and then cut to shape. The film is inserted into a mould cavity, where finally resin is injected onto the back of the fil

1. Cost Effective
Integrate components such as lens, body and keypads into a single component. Saves on tooling costs for individual parts.
2. Wide Spectrum of Formability  
The range includes films that allow products to be molded to nearly any depth; AutoForm for shallow parts, HiForm for true 3D shapes and XtraForm and Aquatex for the ultimate deep forming.
3. Durable long life parts
The unique hardcoated films offer excellent hardness, abrasion and chemical resistance. The film is reverse printed thereby protecting the image without requiring an over laminate.
4. Create High Value Lifestyle Products
Decoration can be undertaken cost effectively for short runs.
5. Create Custom Textures  
By applying Aquatex texturing varnishes custom textures can create the desired look and feel of the part
6. Ideal for Robot Handling
The hardcoated films are available with a matt slip surface suitable for automated stacking and feeding

1)  Telecoms
Key benefits are unique pencil hardness, scratch and abrasion resistance. Autotype hardcoated film can be used to produce flat lenses, housings, keypads or even integrating the housing and lense as undertaken in producing outer casings for clam-shell mobile phones.
2) Automotive
Key benefits are cost reduction vs spray painting, image durability as it is reverse printed and the scratch/abrasion resistance.
  
Many interior trim parts in cars require simulated wood or carbon fibre effect decoration which usually need high gloss surfaces. In Mould Decoration (IMD) is a good way to achieve this, and the deep "french polish" effect achievable using the Autotype In Mould Decoration hardcoated films is extremely attractive. The durability of the surface produced makes for a long lasting quality component.
  
Very fine line printing is necessary to achieve convincing wood grain results, and these are best achieved by using UV inks, which will not dry into the mesh. Use of Aquatex SC is essential to achieve good adhesion with these inks.
  
HVACs (Heater/Ventilation Air Conditioning control panels) were one of the earliest automotive parts to convert to In Mould Decoration (IMD). The areas around the control knobs are very vulnerable to scratching and uncoated films are not capably of fully meeting the OEM specifications. AutoFlex HiForm and XtraForm are highly suited to these applications and can be selectively printed with Aquatex FPH texturing varnish to achieve attractive results. For parts requiring a complete texture the Aquatex FPH can be flood printed over the entire part surface, enabling the use of uncoated films.

The new Autoflex in-mould decoration (IMD) films simplify the production process by reducing the number of manufacturing stages and streamlining part production.
The hard-coated films are reverse printed, formed and cut to shape before being back injection moulded.
Developed for shallow, medium and deep-draw IMD applications, Autotype's new films provide the perfect solution whereby intricate graphics can be reproduced on 3D components, such as HVACs, PRNDLs and other automotive interior parts.
The four films that make up the range have been individually designed to provide a variety of options, enabling end users to specify the film that best meets the demands of different applications.
The range includes Autoflex EBG, which is ideal for cost-effective embossing and shallow-form applications; Autoflex AutoForm, best suited for gently formed parts where micro-cracking must be avoided; and the innovative Autoflex HiForm and robust Autoflex XtraForm films.
HiForm features an ingenious self-healing coating that repairs itself when scratched and is ideal for parts that require a medium depth of form with simplicity of processing, whilst Autoflex XtraForm is designed for deep form applications where maximum draw and extra hardness are required.
The Autoflex IMD range delivers all the design and cost advantages associated with other forms of IMD technology, but also offers a number of additional benefits, including high levels of abrasion resistance for component parts likely to be exposed to excessive wear and tear, and the ability to be used for backlit components or where complex or photographic quality graphics are required.
Perhaps as importantly, as Richard Townsend, Product Manager at Autotype, explains, "Unlike first surface in-mould decoration or the use of uncoated films, Autoflex IMD is an extremely economical technology, offering low unit costs due to savings both in tooling costs and reductions in the number of moulding, assembly and finishing processes and materials required".
