Yield Improvement

Teknek is the market leader in the provision of yield improvement equipment and consumables for industrial processes which use sheeted or continous roll material. We are the single largest supplier of this type of equipment globally and the only one to design and manufacture its products.

Windshields and Bullet Resistant Glass
Rejects are caused by inclusions in the screen print process and inclusions at the lamination process.
Use the XCHP just before screen printing on the glass.

Extruded films
Rejects are caused when the extruder becomes blocked and creates a line in the coating. It then has to be 'bumped' to clear the debris. Using a XCHP to clean the film before the extruder will prevent the debris getting into the extruder head.

Battery manufacture
Rejects are caused when the calendaring rollers, that are used to create a level surface, get contaminated and then start to make an impression in the material. This is a repeating fault and the line must be stopped to clean the rollers. Contamination on the anode, cathode or separator layers should also be removed before assembly. Installing a CH2, NWP or XCH 390 onto the line will improve the yields.

Decorative Laminate
Rejects are caused when a particle is trapped between the steel mould plate and the printed Melamine top layer. When the heat and pressure of the press is applied the dust leaves a indentation on the finished laminate surface. Use of a multi stage XCHP to clean the mould before the lay up improves the yield. When the finished material is transported it can be scratched if there are particles between sheets.

Holograms
Rejects occur when a particle gets trapped between the lacquer coated film and the embossing roller with the hologram shim fitted to it. When this happens the shim will be damaged due to the pressure and will need to be replaced. Cleaning with the XCHP range of machines, will increase the life of the shim.

Medical and Pharmaceutical Products
Rejects are caused by visible particles being trapped in the package. The product may go through terminal sterilisation however no one wants a hair in the package. Installation of the NWP onto the packing machine will prevent this happening. Suitable for use on Flow wrappers, Horizontal form fill and seal machines and vertical form fill and seal systems. Seal integrity for blister packaging is also important. Teknek make special machines to clean the base film and the lidding stock in these high temperature applications. Full validation and wipe down design is available.

Packaging Machines
OEM's of packaging machines can offer a bespoke designed piece of equipment to suit their own design of machine. This allow them to offer the full solution to the end user.

Print Machines
Downtime on a press is one of the biggest concerns to a printer. Using a NWP or XCHP machine to clean the web maintains the throughput of the press, therefore maximising it's efficiency. This applies to flexo, offset, screen, and roto gravure printing.

Photographic Film
In the production of photographic film there are particular processes that take place inside dark rooms. Teknek have built systems to operate in this environment without setting off the films. This can be the sprocketing of the film, or simply the packaging of the final product.

Hard Coat Sheets
In wide screen displays a polycarbonate sheet with a hard coat is placed at the front of the assembly to protect it. This sheet must be very clean. The sheet is cleaned using a vertical cleaner before the coating process to ensure clear coverage.

Bag Making Machines
Many products in the electronic industry, the food industry and the medical industry must be supplied in clean bags. Incorporating a Teknek system at the assembly of the bag will make sure that the inside of the bag is cleaned before it is sealed. The web is cleaned using a XCH 390 before it is folded over.

Inmould Decoration
Injection moulding now uses a technique where the label or finish is applied at the same time as the component is injection moulded. (For example a telephone handset) The decoration is carried on a pre painted polyester web that passes through the tool. Using a specially designed cleaner it is possible to clean this film immediately before it is used.
