Thin glass sheets may be manufactured using a two-part process in which a sheet is first cast and then subsequently reheated and drawn to a required thickness. The latter redrawing process typically results in a sheet with non-uniform thickness and with smaller width than the cast glass block. Experiments suggest that the loss of width can be minimized and the non-uniformities can be essentially confined to thickening at the sheet edges if the heater zone through which the glass is drawn is…

Wrinkling instability of an inhomogeneously stretched viscous sheet

Motivated by the redrawing of hot glass into thin sheets, we investigate the shape and stability of a thin viscous sheet that is inhomogeneously stretched in an imposed non-uniform temperature field.

Out-of-plane buckling in two-dimensional glass drawing

We derive a mathematical model for the drawing of a two-dimensional thin sheet of viscous fluid in the direction of gravity. If the gravitational field is sufficiently strong, then a portion of the

Response to periodic disturbances in the glass redraw process

The redraw process is a method employed for the manufacture of glass sheets required for example special optical filters, bendable displays, or wearable devices. During this process, a glass block is

Investigation of oversized channels in tubular fibre drawing

TLDR
It is established that the observed oversized channels are not consistent with the self-pressurisation model for the sealed tube.

Figure 1: Glass sheet redraw process schematic. A prefabricated glass sheet enters the top of a heater, where it becomes molten. As glass exits the bottom of the heater, it is accelerated using draw

Capillary retraction of the edge of a stretched viscous sheet

Surface tension causes the edge of a fluid sheet to retract. If the sheet is also stretched along its edge then the flow and the rate of retraction are modified. A universal similarity solution for

Viscoelastic effects in film casting

Film casting is an important process in the polymer industry. A thin film of thermoplastic is extruded through a slot die; the sheet is stretched and either falls on a chilled metal roll or passes

Numerical simulation of the film casting process

The film casting process is widely used to produce polymer film: a molten polymer is extruded through a flat die, then stretched in air and cooled on a chill roll. This study is devoted to the

Causes of edge beads in cast films

Cast polymer films are extruded through a uniform thin slit onto a quench roll. Between the die and the quench roll, thick edges called edge beads form, which have to be trimmed from the film, and

Numerical Simulation of the Film Casting Process

Abstract Numerical simulations have been undertaken for the film-casting process with viscoelastic fluids. Viscoelasticity is described by an integral constitutive equation of the K-BKZ type with a

Numerical simulation of the cast film process

The cast film process is studied and a numerical simulation is performed using a finite element method. Two dimensional equations involving the thickness and a mean velocity are used by considering

Mathematical modelling of non-axisymmetric capillary tube drawing

This paper concerns the manufacture of non-axisymmetric capillary tubing via the Vello process, in which molten glass is fed through a die and drawn off vertically. The shape of the cross-section

An asymptotic theory for predicting the thickness distribution and geometry of the boundaries of a thin nearly planar fluid sheet and analyzing the stability of its shape is developed starting from

Nonisothermal two‐dimensional film casting of a viscous polymer

A model is presented for simulating two-dimensional, nonisothermal film casting of a viscous polymer. The model accommodates the effects of inertia and gravity, and allows the thickness of the film
