Dry pressing is generally used for high volume production at low unit cost. Fully automatic presses ranging from 2 to 250 tonne capacity, used in conjunction with tungsten carbide tooling and carefully controlled firings, ensure the highest quality and uniformity. Pressings can be produced in a wide variety of shapes and sizes to suit customers’ individual requirements.
This is a VZS//Seagoe speciality and is used where the size, shape or batch size of components makes dry pressing impracticable or uneconomical. We have a wide range of isostatic mandrels available, offering customers economic manufacture of standard tubular forms.
Machining Before Firing
Parts formed by isostatic and die pressing can be readily machined in the green (unfired) prior to firing. Machining operations include sawing, conventional CNC Milling machines are used to carry out complex finishing operations using diamond tools. Other methods of manufacture include slip casting & extrusion.
Post Firing Processes
Grinding, lapping, polishing & honing are carried out using diamond abrasives. These techniques are used to obtain tight control of dimensions and surface finishes.
By glazing ceramic components the surface area can be kept clean and free from debris. Coloured glazes are also available for identification purposes. Glazes used to resist the metallising temperatures can also be supplied
Metallising & Brazing
We offer ceramic components that are metallised to suit customer requirements. Various options are available including moly-manganese + silver. Advice is available from our qualified material scientists and chemists regarding the metallising & brazing of product to customer design.
