Sealing Tooling For The Thermoforming Industry
Tooling used in the thermoforming industry that contains internal passages used to flow cooling water can leak if porosity of any kind is present. Whether tooling is made from a casting or machined from a solid and then brazed welded, porosity is always present in the casting or brazing. Water flowing through this tooling during a thermoforming process can leak and destroy the manufactured product. Impco dry vacuum/pressure or internal impregnation process can seal fine or gross porosity and ensure your tooling does not leak before they are put into production.
If you are experiencing cooling water leaking from your molds, contact Impco, Inc. for a cost effective solution to save your expensive molds and put them back into production.
