Capabilities Overview
Custom Process Automation & Material Handling
Batching, weighing, and controls, engineered to your process and supported for its lifetime.
Sterling Systems & Controls custom-engineers ingredient batching systems, material weighing systems, and process controls for manufacturers who need accuracy they can measure and traceability they can prove. Every system is built to your specific process — not configured from a product catalog — and supported by the same full-time engineers who designed it, without annual service contracts.
For over 50 years, Sterling has delivered complete manufacturing automation for feed milling and pet food manufacturing, baking and food processing, agriculture and grain handling, and industrial processing operations worldwide.
Our core capabilities span four areas: batching and weighing systems — from micro ingredient scales to full multi-station lines; controls and automation — including process controls, supervisory software, and legacy system upgrades; bulk bag handling — filling and unloading integrated directly into your process; and complete process systems — turnkey plantwide automation from a single accountable source.
