Regarding the confuse of assembly tightness

Some customers have expressed concerns about the tightness experienced during the assembly of the QUADMULA frame and when locking the screws. They feel uneasy about the tightness of the process. However, we value these concerns and would like to provide a detailed explanation.

Firstly, our structural design principles share similarities with some successful products in the market. It is essential that there exists a close fit between the parts. The difference lies in the fact that while other products come with a file, allowing consumers to handle any tolerance issues during assembly, we have chosen not to do so. We aim to deliver a product that is ready for assembly upon receipt, even though this comes at a cost.

During the CNC cutting of carbon fiber sheets, the tool wears out rapidly. Simply put, if the tool and processing conditions are not replaced and controlled, the outer diameter of the first part and the last part will not be the same. Consequently, the finished product has a considerable margin of error. Usually, to reduce costs, minimizing the frequency of tool changes and CNC machine adjustments is a common practice. If the cutting conditions for each part are preset to be larger than the design, the resulting product will not have any issues of being too small. However, we do not follow this approach. We provide an explanation of this, so you can address any issues that arise during the assembly process.

QUADMULA aims to provide customers with a better experience, and therefore, we have chosen the more challenging path of manufacturing. During this process, we frequently replace cutting tools and maintain the CNC machine settings to ensure that the parts remain within the tolerances we demand. In the quality control process, we eliminate a large number of parts that do not meet our standards, finally offering a product that satisfies our own standards to the consumers. For a relatively small company, such an approach may not be economically efficient, but no one can stop us from this steadfast commitment.

Now, let's get to the main point: why does the assembly process feel tight when locking the screws?

Because this is what we intend.

We have designed the screw holes for the 2mm and 5mm carbon plates to be relatively tight. When the base plate and the arm overlap, there must be a slight misalignment between the holes. During the process of locking the screws, the screw threads play a special role. They will shave off any excess carbon fiber, eventually locking into the position we desire. Although there are still individual tolerances for each part, some people find the tightness of screwing acceptable during the process, while others may be concerned. However, under our meticulous quality control, we can achieve the results we hope for.

Lastly, the sequence and method of assembly are crucial. We will soon provide a video that recommends the best assembly sequence officially.

If you are genuinely concerned about the tightness, you can choose to use a file for adjustment. However, we do not recommend this, as it may likely cause other issues, deviating from the original intent of our structural design. Please feel free to contact us for any assembly-related problems. We are here for you.
