Quality Assurance

Why put up with returns, delays, and shipping mistakes that give you a headache? They disrupt production schedules, damage client relationships, and cost you money.

Aria’s stringent quality assurance procedures guarantee that you’ll always get the parts you ordered.

Affordable pricing has no value if the products it buys lack quality and reliability. In 2020, Aria produced and shipped 84.8 percent of parts to spec.

Our quality control preproduction assessment includes technical and material verification. Our experts evaluate the choice of material, parts structure, and production process. We assess potential risks and determine whether the requirements are achievable during the initial development phase.

Verifies that the material is consistent with a production schedule. Material certification is available upon request. It provides detailed information about the grade, heat number, chemical composition, dimensions, and material properties.

In-process quality control is performed by Aria in compliance with our ISO9001:2015 program. First article inspection is a routine inspection that is completed at the production line every two hours.

Before an injection molding project moves into production, a first article inspection is carried out. First article inspections are also available for CNC machining projects upon request. The first article inspection process includes an in-depth examination accompanied by images of the parts.

Includes a dimensional report and a certificate of proper packaging. Inspection reports are performed upon request. They provide a detailed analysis of the parts quantity, critical dimensions, depth, thickness, tolerance, thread, and other essential qualifiers. We guarantee that all parts are packed to prevent damage during transit.

Certificate of Conformance icon 01

Certificate of Conformance

Aria will issue a certificate of conformance that an order has been shipped according to the required specification. Quality reports are available for injection molding, die-casting, stamping, and CNC machining processes.

injection molding materials

Material Certificates

Material certificates verify the chemical composition of raw materials purchased by Aria. This document is generated by the materials supplier and is available with stamping, die-casting, CNC machining, and injection molding manufacturing.

Dimensional Report icon 03

Dimensional Report

Dimensional reports furnish information about the essential dimensions of parts. These parts are randomly chosen from the production area and are inspected and checked with respect to allowed tolerances.

RoHS icon 04

RoHS
Report

RoHS reports verify that no hazardous substances are used in the material or any of its finished products. The report is available with CNC machining and injection molding manufacturing processes.

Our parts verification program is a standard procedure with injection molding projects and is best described as an upgraded first article inspection. It’s available for CNC machining projects that surpass the minimum individual part quantity of 100 units.

This program provides for two sets of parts to be shipped to the customer for testing. Upon approval, the project will proceed to production. A design change is easily accomplished at this stage by submitting a modified drawing to us. If the changes are extensive, the modification will increase the price.

Inspection Equipment

Aria uses coordinate measuring machines to make molding and to verify the dimensions of produced parts. Coordinate measuring machines to capture an object’s series point and determine the object’s dimensions. Coordinate measuring machines are an ideal fit for complex geometries.

The projector is also called an optical comparator. Using an illumination light, it provides a magnified image of a part to measure that part’s dimensions. The image can be compared with the original CAD drawing. The projector is highly effective with smaller components.

Using X-ray fluorescence, a non-harmful analytical technique, we can determine the composition of a material. X-ray fluorescence uses short-wave X-rays or gamma rays to perform qualitative and quantitative analyses of a material’s composition.
