The beginning of the 21st Century was a turning point for vacuum impregnation equipment. In two decades, considerable improvements have been made in impregnation technology that has been unchanged since the 1950s. Since the early 2000s, many companies have brought redesigned and modern equipment in-house.
The five main reasons why companies bring vacuum impregnation in-house are:
In-house impregnation can be done at a fraction of the piece price for an outside service company. Modern equipment uses minimal labor, is small and compact, and is stingy with resources, including sealant and utilities.
Modern impregnation equipment has a variety of features to keep the operator safe. Self-contained modules protect the operator from contact with sealant and hot fluids. Mist eliminators collect water vapor in the exhaust and return it through a drain line for re-use. Better ergonomics allow the operator to slide a lightweight fixture on to the platform for each module.
By operating equipment in-house, companies can eliminate all the costs associated with freight, handling, and inventory. Also, companies will have better lot control and part traceability. Lot traceability is imperative to produce parts efficiently. Having lot control and part traceability measures in place means saving money in the long run, protecting the company from recalls and lost inventory, and keeping the company in compliance with standards and regulations.
Both the size and the modular design of impregnation systems enable manufacturers to position the system within the machining, testing, or build areas, placing the solution where it is needed.
Control of Quality
Vacuum impregnation equipment uses automated and repeatable processes to increase recovery rates and eliminate handling damage. Robotic part handling impregnates parts automatically while reducing the possibility of human error. Stations contain HMI controls cycle status lights that present process data and fault diagnostics.
By integrating modern impregnation systems in-house, companies can remain competitive by controlling the production process, meeting their production volumes, and continuing effectiveness at eliminating casting defects.
