Material and process

The component is made from 303 stainless steel and made by CNC turning process at once. Stainless steel are commonly used, selected based on their electrical conductivity, corrosion resistance, and mechanical stability.

Before the production, we send the material for testing, here is the report:

Material Cert -Non magnetic Stainless steel

CNC machining enables the production of complex geometries, including intricate waveguide channels, threaded interfaces with consistent accuracy, critical for minimizing signal reflection and ensuring optimal microwave transmission.

Here is the waveguide component drawings:

The component size is 24*21mm, it's quite challenging to process, with key difficulties lying in its small size, high precision requirements, and complex processing steps.

Crafted from 303 stainless steel, it is fully CNC milled entirely from a single block of material in one continuous operation. The small dimensions demand extreme stability from the machining equipment, as even minimal tool deflection can compromise accuracy. Meanwhile, tight tolerances require high-precision CNC systems and sharp, wear-resistant tools to ensure every detail, from tiny holes to intricate contour.

After the samples were completed, we sent them to test tolerance, flatness, surface roughness, etc.. There were some areas that did not meet the standards at first time. We made improvements and re-worked the samples.

Finally the samples were qualified and get approval, we move forward for the mass production.

Adding to the complexity is the 18K gold plating on the surface. The plating must adhere uniformly to the small, precision-machined surfaces without affecting dimensional accuracy, requiring strict pre-plating treatments to remove any machining residues. This ensures the gold layer is smooth, consistent in thickness, and functional standards for the final product.

Packing

We conduct thorough inspections of both surface quality and dimensions before shipment. This includes checking for uniform surface finishes, absence of defects like scratches or blemishes, and verifying that all dimensional parameters strictly meet the specified tolerances. Only products passing these rigorous checks are approved for delivery, ensuring they meet the quality requirements.

Finally, the products are packaged and palletized. Each item is first properly wrapped or boxed to prevent scratches or damage, then stacked on standard pallets. The palletized goods are secured with stretch film and strapping to ensure stability during transportation, minimizing shifting or collision risks. This final packaging step ensures safe handling and efficient logistics from our facility to destination.
