MOLDS
for pressing and jiggering
Typically industry standard plaster molds can be substituted with high durability
porous ceramic molds. Substituting ceramic for plaster molds provides several
benefits.
- Ceramic molds provide an increase in mold life of >10X. Seneca
Ceramics has demonstrated over 7000 cycles pressing a standard clay body
compared to average life of < 500 cycles for plaster.
- Mold release has been demonstrated at less than 1 second on
non-symmetrical shapes
- Almost no dwell time
- No sticking or tearing at mold surface
- High resolution and increased surface relief patterns can
also be provided based on the inherent strength of the ceramic substrate.
- Ceramic mold benefits are the same whether pressing clay bodies or
hydro-plastic forming of high purity technical ceramics.
Process costs can be significantly reduced affecting total cost of ownership.
- More capacity and lower standard costs
- Less downtime from fewer mold change-overs
- Higher throughput time with virtually no dwell time under pressure.
- Less total cost of molds on mold cost per yielded piece basis
for elastic film products
Porosity can be controlled in porcelain molds that would allow pressure
ejection of film molded products such as latex gloves. Reverse molding
would provide fine surface features from the mold surface.
for pressure casting
High strength porosity can be offered in pressure casting molds. The
strength and stiffness of the porous layer would allow fine surface detail on
the mold surface. It would allow rapid extraction of water for faster
throughput.
