4.1. Customer-Centric Approach

We believe that our client satisfaction is the key to a good quality control program. Therefore, we stay in close communication with our clients, listen carefully to the parameters and design requirements shared with us, and perform as per their requirements. In case, we have a query related to the order, we communicate and clarify with our clients. This is our first step to ensure that we get the product right and as per the requirements of our clients.

4.2. Understanding The Design

Our design team has the prime objective of acquiring the CAD design for all products. The prime focus of the design team is to understand the product and see the tolerances allowed for the product.

4.3. Finalizing The Approach

The next step is to finalize the process. At this stage of quality control, our teams finalize the process to be adopted. Importance is given to the most cost-effective and technologically advanced process. It is followed by an arrangement of any documents required for the process completion. Once it has been decided which process is the best for the part, we start the machining process. Other aspects that we consider at this stage are the timelines of the project and the amount of time we have for the process. Consequently, we make slight changes according to the time we have on our hands and then finalize the approach.

4.4 Material Inspection

In order to maintain a good CNC machining quality control program, it is essential to account for the material and quality of the material to be used. So, we always purchase the materials from big companies and apply material inspection before machining, we make sure it meets the requirements of our client. Also, we ensure that the material we use has the certification required by our client's relevant industry or country. As such, we eradicate any material issues at a very early stage of the process. Moreover, if our client has some regulatory requirements to incorporate into the product, we can do it.
