Quality Assurance

Uncompromising Quality Assurance

Each time materials enter our warehouse, they undergo thorough spectroscopic analysis to ensure their precise composition and characteristics. To provide you with complete confidence in the parts you receive, we include mill certs and testing reports with every shipment.
We offer a 100% full refund policy.

Our quality process is run through the whole projects from RFQs to production shipment.

Two independent reviews of the purchase order is where our QA begins, determining that there are no questions or conflicts regarding dimensions, material, quantities, or delivery dates.

Then reviewed by experienced personnel involved in the set up and production and individual inspection reports are made for each operation that is required to produce the part.

All special quality needs and instructions are documented and inspection intervals are then assigned based on tolerances, quantities or complexity of the part.

We minimize risk by tracking and analyzing every step of our manufacturing process to minimize part to part variation, and assure consistent, reliable quality for every part, every time.

Quality Control is Our Number one Priority for All CNC Precision Machining Products

ProtoTech Machining’s CNC machining services, vacuum casting and swiss turning are dedicated to surpassing customer expectations in quality, safety, cost, delivery, and value. Our primary focus is to proactively identify and meet customer needs while complying with all relevant standards and customer-specific requirements. Calibration and upkeep protocols form a crucial part of our maintenance regimen for all equipment, including CNC machining, rapid prototyping and direct metal laser sintering (DMLS) systems.

Incremental Processes Ensuring Quality

Customer Communication
In accordance with our commitment to exceed our customer’s expectations, ProtoTech Machining highlights effective customer communication as an essential element of delivering customer satisfaction.
Products and Services
The monitoring and measurement program for all precision machining products is defined in drawings and specifications, production routers, purchasing documents and in inspection and testing procedures.
Verification of Purchased Products
All purchased products are subjected to a visual inspection by the receiving inspector. Designated products are also subjected to a more detailed and technical quality control (QC) inspection.
In-Process Inspections
In-process inspections are in the form of first article inspections and operator inspections to ensure our quality and the on-time delivery of completed orders to our customers.

Final Acceptance Inspection

Completed CNC machining services yield products that undergo the concluding QC scrutiny. Initially, inspectors ensure the execution of all predefined and ongoing examinations. Following this, they conduct the remaining assessments, employing a Coordinate Measuring Machine (CMM) as needed, to validate product conformity. 

Our quality management system’s consistency and proficiency are evaluated by internal audits, measuring quality performance, and gauging customer satisfaction.

Quality engineers handle the verification of product specs and technical details for incoming materials, ensuring they align with drawing, customer-end application requirements, and technical specifications. All initial verifications, like CNC machining services, 3D printing, and aluminum casting molds, must be met for the procured materials. After certification, the quality team confirms that materials, possibly involving carbon fiber manufacturing or sheet metal fabrication, are inspected and meet supplier-end standards.
