Solenoids at Work in SCR Systems

Diesel engine manufacturers are utilizing Selective Catalytic Reduction (SCR) technology to meet more stringent emissions regulations. These SCR systems use diesel exhaust fluid, better known as AdBlue®, injected into the exhaust stream to create a chemical composition that changes the exhaust into a mixture of nitrogen and oxygen.

Our Process

Step 1 / Initial Review

Our engineering team works directly with you to determine the viability of your program and identify the best solution based on your specifications.

Step 2 / Quote

Quotes include all costs related to your project - tooling, prototype, piece part, production and project specific costs.

Step 3 / Design Review & Prototypes

Our engineering team reviews the design with you and makes any adjustments needed. Prototypes are built according to design specifications for testing.

Step 4 / Testing

Prototypes are tested according to your specifications, with all relevant test data provided to you for evaluation.

Step 5 / APQP

DFMEA’s, PFMEA’s, control plans and process flow diagrams are started to drive the product intent design.

Step 6 / Pre-Production

Working drawings are developed for production. A second prototype build and a set of production parts are made from tooling and thoroughly tested.

Step 7 / PPAP/Production

The final design along with the PPAP (Production Part Approval Process) is developed and the new product enters production.

Step 8 / Ongoing Improvements

Our team collaborates with you to continue making improvements to the product to best meet your needs, increasing efficiency and reducing cost.
