The lab capabilities include the following:
- Machine Direction Orientation (MDO)
- Compression Roll Drawing (CRD)
- Transverse Direction Orientation (TDO)
- Heat setting/Annealing in either MD or TD
- Corona Treating System – single sided and two-sided
|
- Sequential, in-line, biaxial orientation capability
- Resin Drying
- Extrusion (Single/Multiple Layer – Single/Twin Screw
- Casting and controlled quenching of Sheet/Film
- Thickness measuring via X-Ray gauge, (Up & Downstream)
| Extrusion and Casting
The Extrusion and Casting section consists of a single or multiple extruders, with general purpose screws, melt pipe system and choice of dies, and a casting unit for film or sheet production. Customers have the option to pin the extrudate to the casting roll by a variety of means.
Machine Direction Orienter (MDO)
The Marshall and Williams Plastics Lab MDO can be used to produce mono-axial oriented films, with or without Compression Roll Drawing (CRD), as well as biaxially oriented film and sheet when used in conjunction with the TDO. The system consists of six 30 inch face width rolls. The first five rolls are thermally controlled by internal oil heating and the last roll has water-cooling. Maximum oil temperature is 550 degrees F. Water temperature range is 50 - 275 degrees F. There are five drives; preheat 1, pre-heat 2 & slow draw, fast draw, anneal 1, and cooling.
Transverse Direction Orienter (TDO)
The Marshall and Williams Plastics Lab TDO consists of two horizontal chain systems between which the material is drawn, or stretched, in accordance with a predetermined divergence pattern. Horizontally mounted sprockets at the delivery end of the TDO drives the chain.
