Quality Assurance & Control
From Ore to Plant to Clients Well
Cradle to Grave Testing by Stim-Lab
With quality the cornerstone of our company culture, one of our most important goals is to exceed your expectations in product quality and consistency with every shipment.
Each truckload of ore coming to the plant is sampled, rigorously inspected and tested before being accepted.
All manufacturing plants are ISO 9001 certified with strict quality control standards. Our highly experienced Quality Assurance Coordinators rigorously follow quality assurance procedures to maintain conformance to the finished product specifications.
Only the proppants that conform to these product specifications are prepared for packaging and shipping to the clients.
During production throughout the day, samplers "sweep" across finished product line at hourly intervals to collect samples for testing.
Testing of Finished Products
Samples are collected from each bulk bag of finished products and the ISO/API proppant tests are conducted for the key proppant characteristics, such as the apparent specific gravity, bulk density, screen analysis, crush rate, and turbidity, in the Quality Control lab. These test results are documented and archived for future reference.
An individual QA/QC certificate is attached to each bulk bag once the testing has confirmed that the finished product has met or exceeded our manufacturing standards for the grade of proppant being produced. Each bulk bag is assigned to a specific lot and the lot number is documented. Therefore, the quality of each bulk bag can be traced to its original lot number.
