Explore our core precision-machined hardware designed to maintain signal integrity, withstand harsh outdoor environments, and support robust telecom network deployment.
Modern telecommunications infrastructure is the backbone of the global digital economy. As the world transitions rapidly from 5G to advanced 5G-Reduced Capability (RedCap) and prepares for the future deployment of 6G and Low Earth Orbit (LEO) satellite constellations, the demands on physical hardware have reached unprecedented levels. High-frequency signal transmission, dense hardware deployments, and extreme outdoor weather conditions require mechanical components with micron-level tolerances, exceptional electrical conductivity, and long-term durability. This is where precision turned metal parts become indispensable.
Turned metal parts, fabricated using advanced CNC Swiss turning and multi-axis lathe technologies, form the structural and electrical links within telecommunication systems. These components include RF (Radio Frequency) connectors, coaxial pins, waveguide couplers, antenna bases, fiber optic transceiver housings, and thermal management hardware. In high-frequency bands, even a microscopic deviation in component geometry can cause significant signal attenuation, impedance mismatch, or return loss. Consequently, leading telecommunication equipment manufacturers rely on specialized CNC turning suppliers to deliver parts that guarantee flawless performance over decades of operation.
The global telecommunications hardware market is experiencing a massive shift toward localized, high-resilience supply chains. Base stations, small cells, and satellite ground terminals are being deployed in larger quantities than ever before. This rapid scaling demands manufacturing partners capable of balancing high-volume output with strict quality control. The integration of IoT (Internet of Things) devices and edge computing nodes further drives the miniaturization of telecom hardware. CNC turning facilities must adapt by upgrading to high-speed, automated Swiss-type lathes capable of machining micro-components with diameters as small as 0.5mm, while maintaining tolerances within ±0.005mm.
High-precision male and female contact pins, SMA/SMB/N-type connectors, and coupling nuts machined from premium brass or copper alloys to ensure low insertion loss.
Fiber optic ferrules, alignment sleeves, and transceiver bodies that demand sub-micron accuracy to prevent light dispersion and preserve high-speed data transmission.
Heavy-duty standoff pillars, custom threaded fasteners, and locking nuts engineered from stainless steel and aluminum to secure outdoor base station enclosures.
We uphold quality standards throughout our manufacturing process and possess both ISO9001:2008 and IATF 16949 quality certification. FRIMA is devoted to offering quality CNC machined parts at an affordable price.
FRIMA is committed to providing high quality products to our customers and thus to their customers. The key to our success is actively engaging with customers throughout the product design, development and manufacturing lifecycle.
Our 8,000 sq. ft. machine shop in Ningbo, China has nearly every precision CNC manufacturing capability you could possibly need. If you need real-time tools for milling, drilling, tapping, facing, cross-drilling and turning all kinds of metal and plastic parts, there is no better supplier than FRIMA. We have a wide range of processing equipment and sophisticated inspection equipment to handle any complex or tight tolerance product.
We also offer professional surface treatment services for all machined parts, including grinding, deburring, heat treatment, electroplating, coating, painting, etc. Our high-quality manufacturing solutions can complete your design in a few hours. This allows you to test your product thoroughly and make any necessary changes to refine your design before the product goes into full production.
5G networks rely heavily on Massive MIMO (Multiple Input Multiple Output) technology, which utilizes dozens of small antennas integrated into a single array. Each antenna element requires individual RF feeds and filters. CNC turned brass and aluminum components, such as tuning screws, resonators, and connectors, are vital to these systems. These parts must exhibit extremely low surface roughness (Ra < 0.4 μm) and be plated with silver or gold to minimize skin effect losses at high frequencies (up to 40 GHz and beyond).
With the commercialization of LEO satellite constellations, ground terminal antennas (such as phased array antennas) require precise mechanical positioning and tracking systems. Custom motor shafts, gear components, and pivot pins manufactured via precision turning allow ground terminals to align precisely with satellites moving across the sky. These parts are typically machined from high-strength stainless steel or titanium alloys to withstand extreme environmental fluctuations without deformation.
Telecom infrastructure is deployed globally, from freezing arctic zones to scorching deserts. Outdoor enclosures protecting sensitive electronics use specialized turned metal seals, pressure relief valves, and heavy-duty blind nuts. These parts must resist galvanic corrosion. FRIMA's capability to machine marine-grade stainless steel (SUS316) and apply advanced anodizing or passivation treatments ensures these assemblies remain hermetically sealed for over 20 years.
The backhaul network that connects local cell towers to the core network relies on fiber optics. The optical transceivers (such as SFP, QSFP, and OSFP modules) require turned metal housings and locking mechanisms with exceptionally tight tolerances. A misalignment of just 1 micron in the optical ferrule can lead to complete signal loss. Precision CNC turning ensures that the mechanical mating interfaces of these fiber optic connectors are flawlessly aligned every single time.

As the telecommunication industry marches toward 6G, several key trends are reshaping the requirements for turned metal parts:
Choosing the correct raw material is critical for telecom performance. Brass (C36000 series) remains the industry standard for RF connectors due to its excellent machinability and conductivity. For structural components exposed to high stress and wind loads, Stainless Steel (SUS303, SUS304, SUS316) offers superior tensile strength and rust resistance. When thermal dissipation is the primary concern, such as in high-power remote radio heads (RRH), Aluminum (Al6061, Al7075) is selected for its lightweight properties and excellent thermal conductivity. FRIMA maintains robust partnerships with certified material suppliers to ensure all incoming metals meet strict chemical composition and mechanical property standards.
Our company is based in Ningbo, home to the largest export port in China – Ningbo Port. We are also very close to Shanghai airport, making it easy to keep fast air freight to your destination.
