DFM (Design for Manufacturing):

That is, without affecting product functions, product design is more conducive to production and product manufacturability is improved, thereby simplifying the process flow, shortening production time, ensuring product quality, and reducing project costs.

For Ebardl Precision, the core of DFM is to actively communicate with customers, think about what customers think, and become a better partner for customers. Therefore, Ebardl is committed to providing professional DFM analysis reports at the early stage of the project to help customers discover problems in design, appearance, function, processing, etc. early, and through improvement plans, reduce the time of repeated trial production verification, and save labor and material costs. , increase the speed of mass production and accelerate the time to market.

Manufacturability Analysis Of Product Design(DFM)

To kick off the project, Ebardl immediately launched a detailed analysis upon receiving the complete product design documents to check for any discrepancies or point out areas that might need to be modified to improve the product's manufacturability.

When working with this drone company, Ebardl made the following suggestions:

Tip 1:

The positions marked in green in the picture require post-processing to achieve the required flatness and tolerance after anodizing. Star pointed out to customers the risk in processing, that is, when processing to the outer wall, it may damage the nearby coating surface.

The customer responded that he wanted to protect the coating at this location, so we modified the milling procedure to leave a 0.5 mm gap from the outer wall. This would protect the anodized surface from damage while achieving the flatness required by the customer.

Tip 2:

The position shown in the figure is the right Angle at which two planes meet. The CAD drawing is a sharp right Angle, but in the actual machining here will leave a R2 or 2 mm radius of the arc. This is because in the use of rotary tools, due to the limitation of the trajectory of motion, leaving a slight arc here is inevitable. The customer accepted our modification.

Tip 3:

Most bosses are smooth at the ends, transitioning from arcs to flat surfaces. However, the top line, marked in blue in the picture below, has an arc at the end in the opposite direction to the other lines.

Skadden Modelling is concerned that this may be a design error. After communicating with the customer, they confirmed that this was a special design and therefore did not modify the CAD drawings. Meticulous and rigorous communication is one of the important processes to ensure that the details are correct before processing.

Production process

Once the raw materials were available, we began to prepare separate clamping systems for the three workpieces.

The most efficient way to machine housings is to place multiple jigs in one machine. After one side is completed, it is taken out, turned over, mounted on the adjacent fixture and processed.

Sandblasting

The surface of the freshly milled aluminum alloy has a polished effect, almost as shiny as chrome. However, if not treated, the surface of the aluminum alloy exposed to the air will rapidly oxidize and discolor.

After sandblasting, the surface of the workpiece has a uniform matte effect. Next, apply a transparent alodine treatment to the surface of the shell. Alodine is a chemical surface treatment used on aluminum, magnesium and other metals. The surface is usually clear, used to resist corrosion and as a base for other surface treatments such as paint or powder coating.

Through repeated communication with the customer and careful confirmation during the project, Ebardl successfully delivered the product to the customer, which was highly appreciated by the customer. Ebardl, to be a better partner for customers.

"For small and medium-sized enterprises, one of the biggest benefits of cooperating with Ebardl is that they can get a one-stop solution. Ebardl has the ability to provide complete processing services including CNC machining, anodizing and laser etching, etc.
