Why Us?
We don't just manufacture shafts; we create custom components to meet the unique needs of your industry. For automotive manufacturers, our shafts provide the torque resistance and dimensional accuracy required for powertrains and drivetrains. For heavy machinery, we enhance durability through reinforced design and heat-treated carbon steel. For automation and robotics, our ultra-precision shafts minimize friction and vibration. No matter your industry, we customize shaft designs to your specific operating conditions to maximize performance and minimize downtime.
Our carbon steel precision CNC machining shafts perfectly balance performance and cost: affordable material costs, excellent machinability, high-precision capabilities, and superior strength — outperforming other alternatives in most industrial environments. We source only high-purity carbon steel (1018, 1045, 4140, 4340) to ensure consistent material properties, eliminating the risk of weak points or defects. Choose carbon steel for long-term value, fewer replacements, and a lower total cost of ownership.
Our factory is equipped with advanced five-axis CNC machining centers, automated loading and unloading systems, and real-time quality monitoring tools. We achieve tolerances as low as ±0.003 mm, surface finishes of Ra 0.4 microns, and geometric accuracy that eliminates assembly gaps. Whether you need 10 prototypes or 10,000 production parts, our certified CNC operators deliver on time, every time.
Our engineering team offers free design consultations to optimize axis designs, balancing manufacturability, cost, and performance. We provide rapid prototyping services with cycles as short as 3–5 business days and mass production cycles of 7–15 days. Small-batch orders start from just 5 pieces. Our global shipping and logistics network ensures your products arrive on time, no matter where in the world you are.
FRIMA believes in full transparency — so you never have to guess about the quality of your shafts. Our quality control process starts with material inspection (chemical composition & mechanical properties). During machining, we use CMM and laser measurement tools for in-process inspections. After production, every shaft undergoes hardness testing, surface roughness analysis, and dimensional verification. We provide detailed inspection reports, material test certificates (MTC), and ISO 9001:2015 / IATF 16949 certifications with every order.
FAQs
-
Q I don't have CAD drawings — can you still help me with machining?A This is not a problem for us. We can turn your idea into the finished part. No worries!
-
Q What materials do you CNC machine?A We can machine various materials, including alloy steel and carbon steel (#45, Q235, 12L14, 11SMPb30, 42CrMo, etc.); stainless steel (SS301, 303, 304, 316, 420, etc.); aluminum (2024, 5052, 6061, 6082, 7075, etc.); and many others.
-
Q What kind of material do you stock?A Normally we do not hold stock for metal or plastic materials, as all materials are ordered specifically according to each customer's design requirements.
-
Q Are you a manufacturer or a trading company?A We have 2 manufacturing factories and 1 newly built warehouse in Ningbo, Zhejiang, China, covering an area of 1,500 square meters.
-
Q Will you sign a Non-Disclosure Agreement (NDA) upon request?A All your drawings are protected by confidentiality obligations. We will sign an NDA per your request.
-
Q What is the minimum order quantity, and how fast can you deliver?A Our minimum order quantity is just 5 pieces. Prototyping cycles are as short as 3–5 business days, while mass production cycles typically range from 7–15 business days, depending on complexity and volume.
