Edge Condition
Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print.
Quality Control
At EnQi Manufacturing, quality is our top priority. We implement rigorous quality control measures throughout the entire manufacturing process to ensure that every part meets the highest standards of precision and reliability. Our comprehensive quality assurance system includes advanced inspection tools and techniques to maintain consistency and excellence in our products.
In-Process Inspections
Our quality control begins with in-process inspections, where each part is checked at various stages of production to ensure adherence to design specifications. This proactive approach helps identify and correct any issues early in the manufacturing process.
Final Inspections
Before any part leaves our facility, it undergoes a thorough final inspection to verify its quality and precision. We use advanced measurement tools and techniques to ensure that each part meets the required specifications and standards.
Precision Measurement Tools
We utilize a range of precision measurement tools, including Coordinate Measuring Machines (CMM), optical comparators, and laser scanners, to accurately measure the dimensions and tolerances of our CNC machined parts. These tools enable us to maintain tight tolerances and high precision in every component we produce.
