An Introduction to Pad Printing
Pad printing is a printing process that can transfer a 2-D image onto a 3-D object.
Pad Printing is an indirect offset printing process that involves an image being transferred from a printing plate via a silicone pad onto a moulded part. There are two common methods used for inking the plates: - The open ink well system (old system) and the sealed ink system (closed cup new system).
Sealed ink-cup Pad Printing systems (newest system) employs a sealed inverted container (ink cup), which acts as the ink supply. A ceramic ring with a highly polished working edge provides the seal against the printing plate. The closed cup system is used by Ardtech Industries as it is a much cleaner and more stable system.
The printing of injection moulded housings is a popular way of adding information and increasing the visual appearance of the moulded product.
The main advantage of Pad Printing when compared with other similar printing methods is the unique possibility of printing many types of irregular shaped moulding surfaces, while other printing methods are often limited to flat and/or round surfaces.
Ardtech Industries has, and continues to, successfully Pad Print, with high precision and accuracy, in a wide range of colours on injection moulded products, produced in various materials and in complex shapes.
OUltrasonic welding is where pieces of plastic or other materials are welded together by high frequency vibrations. The pieces are held together under high pressure so ensure the weld is successful. There is no need for bolts, screws, glue or any other consumables – meaning it can be very cost effective. It is also extremely fast – taking only seconds.
