Quality Assurance

Rainhouse Can Inspect to Any Specification, For Any Application.

Quality assurance services are of utmost importance to Rainhouse. Our ISO 9001:2015 certified quality management system guarantees that every CNC product we make will meet your requirements. Our inspection report will be as detailed as you require.

Quality Assurance is Our Number One Priority

Rainhouse takes pride in our Canadian Controlled Goods registration, ISO 9001:2015 certification, and Class MA Boiler and Pressure Vessel License (License No.: LPB0201365).


The Rainhouse quality team is essential in our machine manufacturing process. Rainhouse manufactures CNC parts for a wide range of industries which require high-precision CNC parts with tight tolerances. Our quality technicians are trained to meet ISO certification requirements and provide tight tolerances on every CNC product that leaves our shop.

Quality Assurance Services

A First Article Inspection (FAI) verifies that the production process creates parts that conform to customer requirements. Although the FAI occurs after the CNC machining is done, an FAI is designed before the manufacturing process starts to guarantee that machines are set up correctly.


Throughout the machining and manufacturing process, our quality team works with our CNC machinist to create In Process Checks (IPCs). IPCs examine product parameters at each step of creation to confirm they’re within our client’s specifications.


Rainhouse’s quality team creates a Certificate of Conformance (CoC) for very batch of parts we make. This official certification declares that all parts conform to our customer’s requirements. CoC also confirms the imported product meets the required international standard(s).


Material Traceability Certifications (MTCs) are included with all CNC machined parts by default.

Third-Party Quality Assurance Services

Rainhouse also offers third-party quality assurance services for inspecting parts made by other manufacturers. Although inspection reports are not created by default, Rainhouse can provide printed or digital third-party inspection reports for any percent of the products inspected. We can create reports that they have the exact measurements (called out in the part drawing) of at least one part of the batch to show that it’s within specifications.
