Our ACT coatings provide essential dimensional stability and durability for the automated feeding process. We supply single items or a set with a spout bowl, orifice ring, stirrer tube and plungers - recommended for maximum durability and high quality glass.
Any form of orifice ring can be coated, ranging from a 30cm quadruple gob for high volume container production, to a small 12cm single gob for small scale glass forming. The coating can extend the service life to up to two years, offering major downtime benefits by removing the need for regular orifice ring changes. We can fully coat, band coat or partial coat the ring to best suit your needs.
Applying an ACT coating to the stirrer tube will help minimise typical problems such as:
- Uneven wear on the bottom edge of the tube.
- Deteriorating glass flow control.
- Glass leakage during orifice ring changes.
- Eroded wall thickness at the glass line.
Coatings can be either full, reaching above the glass line, or partial, around the bottom edge of the tube.
An ACT coating, extending above the glass line, will minimise corrosion from molten glass and retain the shape of the plunger. This will reduce problems such as deteriorating gob shape control and defects such as cord in the finished product.
