Specialty Processes

Standard Heat Sealing- The process of sealing thermoplastics together using heat and pressure.  The direct contact method of sealing uses a constantly heated die to heat a specific contact area to seal the thermoplastics together. This is one of the most commonly used processes to connect objects.

Ultrasonic Welding/Sealing- Industrial technique where high frequency ultrasonic acoustic vibrations are applied to work pieces that are being held together in order to create a solid-state weld. In this method of welding, no screws, bolts, nails, adhesives, soldering materials, or other connecting devices are necessary.

Multi-layer Lamination- Lamination process where multiple material layers are bonded together using adhesive, heat, or pressure.  Different materials can be used for each layer based on the specification, creating a hybrid layer. An example of multi-layer lamination would be a plastic film being placed on either side of a sheet of glass.

Adhesive Coating- Process of covering a surface with a substrate.  Adhesive coatings may be used in things like adhesive tape and pressure-sensitive labels in order to attach them to other objects at any point in time after its creation with ease. Additionally, because of the use of a substrate to create the bond, the connection can be made in any temperature and does not require extreme temperatures to form the bond.

Hot Stamping- A dry printing method of lithography where pre-dried ink/foils are transferred to a surface at high temperatures. It is a non-pollutant method which can be formed in a variety of colors. A stamping device is given a coat of dry paint with the desired print. After being heated to high temperatures, it is pressed against the object which requires the print, instilling the image into the product.
