Controlled formula and bill of materials
Each formulation is defined in our master formula database and produced against a controlled bill of materials. If a production document and the master formula disagree, the master formula governs and engineering is notified. Only approved raw materials may be used.
Unique lot number and full traceability
Each batch receives a unique lot number recorded in a controlled log, capturing the supplier lot numbers and the actual mass of every raw material used.
Clean, controlled handling
Equipment is verified clean before each batch to prevent cross-contamination, and moisture-sensitive formulations are handled under inert-gas blanketing.
Controlled addition and blending
Raw materials are added to the formulation, then blended to a homogeneous state. No substitution is ever permitted without engineering and client approval.
In-process sampling
A quality control sample is drawn after final inspection and sealed before the batch is closed, then held for 5 years for reference, if testing is ever needed.
Release testing against defined criteria
Finished product is tested against defined acceptance criteria, and verification that the constituent proportions fall within tolerance of the formula targets. Results are recorded against the lot.
Hold, quarantine, and corrective action
Any lot outside its acceptance criteria is placed on hold and quarantined and will not ship until engineering and quality authorize disposition. Out-of-specification results trigger a documented root-cause investigation and corrective action.
Batch release by Quality Control
Products are only released after every acceptance criterion has been met, and only after authorization by our Quality Control department.
Retention samples and retained records
A sealed retention sample is held for every lot for a minimum of five years, and the production record is retained with the order.
Change control and customer notification
Any change to raw materials, suppliers, methods, equipment, test methods, packaging, or manufacturing location requires internal approval and customer notification where applicable before shipment.
