Featured Process

Parts washer in Manitowoc facility

A recent example of our on-going continuous improvement efforts is the installation of a new, state of the art parts washing system.  This system allows LDI to clean parts that are machined in either oil or coolant to comply with stringent ISO cleanliness standards.

By using this advanced technology, we are able to clean parts in an environmentally safe manner recapturing and reusing the cleaning solutions, while also providing air quality protection to the operators by using a sealed chamber. Potential wash operations include agitation, rotation, spray, or ultra sound.

Because the system is programmable, the operators cannot only determine the most efficient method to clean our large variety of part configurations and materials, but also assign a program number to that part and store it in the system controller.  When parts are ready for cleaning the operator simply enters the program number and starts the machine, greatly reducing set up and process time while significantly enhancing the level of cleanliness.
