Description:

ISO Type 4

LeanRock is formulated specifically for laboratories who want to pour small batches (about 6) and have working models ready in 15 minutes.

Small batch processing is based on lean principals to improve work flow and reduce wait time because models can be trimmed and pinned after only 15 minutes, decreasing downtime waiting for stone to set. This enables smaller batches to be sent down the line for trimming, eliminating the “bottleneck” associated with large batches hitting all at once, giving you more controlled release of product.

The decreased processing time also speeds up remakes and those emergency repairs needed in a hurry.
