In Mould Labelling

In Mould Labelling or Decoration provides a diverse alternative to industrial labels / labelling, product marking and decoration.

Customark as specialist printers have become a well established In Mould Label(s) Supplier and provides side by side support for new and existing projects. Due to the tangible gains in production efficiencies that were experienced by the early adopters of this process, it has resulted in wide spread and development. This is particularly widespread in the areas of automotive and consumer products where backlighting of switchgear is achieved with plastic injection moulding.

This process has rapidly advanced into In-Mould structured electronics (IMSE) where embedded electronics are applied pre-moulded appliques.


In Mould Labelling (IML)
This is the most basic form of the process and technology is used to decorate simple plastic products such as packaging containers. This process can be used to follow simple 3D profiles such as display lenses. This printed foil with deform and follow a cavity profile with careful mould tool design. The foil can either be placed on pins during the process cycle of the moulding process or simply be placed in a cavity using either an interface fit or by means of static charge.

In Mould Decoration (IMD)
This more advanced process requires the printed foil to be formed by Hy.Tech Forming Systems (Euro) Ltd using AccuForm® high pressure forming process. The formed printed sheet is then trimmed to remove excess waste either by hand trimming or matched metal tooling.

Some more advanced mould tooling can ‘nip’ the waste during the moulding process. The subsequent formed and trimmed part is then placed in the mould process cycle. The result of this process can be seen in most automotive vehicles that have ‘back-lit’ switches on their interior controls.

Production of the foil or insert can be printed using a range of methods. Predominantly the high-volume packaging process is printed using an offset litho process and fed automatically during the mould cycle. The more technical projects use screen printing, where the characteristics of the foil or insert are a strategic element of the finished product. Digital printing can be used in some instances where a low volume / full colour finish is required. This process normally requires a supporting back floor of high temperature ink using a screen process to protect the digital ink from gate wash.

Customark’s process experience allows our customers to benefit from just simple advice to project support to liaising with formers and moulders. Typically, the process requires careful and experienced mould tool design considerations from the start.

In some instances, mould tools do not require modifications but it is normal for existing process tooling to have some form of adaptation.

Customark work in close strategic partnership with High.Tech Forming Systems (Euro) Ltd and technically experienced moulding partners to bring projects to market using specialist film manufacturers such as Bayer, Sabic and Macdermid Autotype. This combined experience reduces costs and lead times for bringing projects to market.

As will all our other services, Customark are always on hand to assist with customers on any new design or existing processes. We would be delighted to offer any support, even its just an idea that needs sounding out.
