Tempo’s patented
Dry Molding Process is ideal for thin wall molding (under 6mm thickness) for
SEKISUI which is a very stiff material, not smooth flowing inside mold geometry.
Tempo’s Open Architecture mold construction allows for molded undercuts and
no-draft conditions where designs require. Customers save significant mold costs
as Tempo machinery accommodates single and double cavity molds for early
production phases, with additional capacity added as needed.
SEKISUI is chemically resistant to virtually all aqueous media including
dilute acids and alkalis. SEKISUI is resistant to water-miscible alcohols
such as methanol, ethanol, i-propanol and also to silicone oils.
SEKISUI has successfully tested for 30 days immersed in #1 Diesel (kerosene),
it has limited resistance to paraffin oils, #2 Diesel and Vaseline. These
substances may attack the surface of foamed materials after long-term
contact and may cause deformation through shrinkage.

SEKISUI (COMING SOON).

require each side wall of the mold to retract. Heat controls for every
mold segment allow adjustment for nice surface finish.

High temperature floats for Inspiron Respiratory
bedside humidifier. Evaluation of foamed polycarbonate and NOREL™ showed
excessive weight. Tempo provided SEKISUI F-100 copolymer foam solution half
the weight of the foamed injection resins.
These floats are sized 40.6mm x 22.8mm x 6.3mm (1.6” x .9” x .25”), with 5mm
thick neck to fit into slide holder, (note orange valve attached to slide holder
in photo) |

This four cavity aluminum
mold saved Inspiron Respiratory $thousands compared with the injection
molds made for testing floats molded from high temperature foamed
injection resins. |
