• Custom Solutions for Every Industry:

At SP-MFG, we specialize in delivering highly customized CNC machining services that cater to the unique demands of industries ranging from robotics and aerospace to medical devices and consumer electronics. Our 14 advanced CNC lathes, complemented by 5-axis machining centers, enable us to handle complex geometries with exceptional precision—down to ±0.01mm tolerances—making us a trusted partner for high-precision components. One standout example is our collaboration with a U.S.-based aerospace startup requiring titanium alloy housings for next-generation UAVs. The design featured intricate internal channels and tight dimensional control, demanding both material expertise and multi-axis machining capability. We successfully delivered over 12,000 units within a 21-day turnaround, meeting all technical specifications and passing rigorous flight simulation tests. Another notable case involved a European medical device manufacturer needing biocompatible stainless steel parts for implantable surgical tools. We implemented mirror polishing (Ra ≤ 0.1μm) and ensured full compliance with ISO 9001 and EU 2015/863 standards. The project was completed with zero defects and has since been used in over 5,000 surgeries worldwide. With a minimum order quantity of just one piece, we empower startups and enterprises alike to prototype quickly and scale efficiently. Our R&D team of three engineers, all holding undergraduate degrees, works closely with clients to optimize designs for manufacturability (DFM), reducing costs and lead times. Whether it’s aluminum brackets for industrial robots or brass fittings for smart home devices, SP-MFG delivers consistent, high-quality results—proving that customization isn’t just possible; it’s our core strength.

--- Commitment to Quality and Compliance ---

• Industry Certifications and Standards:

SP-MFG takes pride in its unwavering adherence to global quality and environmental standards, ensuring every product meets the highest benchmarks required by international markets. Our company holds multiple critical certifications, including ISO 9001 (Certificate No. HG23Q0416R0S, issued Nov 22, 2023), CE (Certificate No. HX250202010356, issued Feb 20, 2025), RoHS (Certificate No. LCT-241202011620, issued Dec 27, 2024), and (EU) 2015/863 (Certificate No. LCT-241202011620, issued Dec 27, 2024). These certifications validate our compliance with stringent safety, environmental, and performance requirements across Europe, North America, and beyond. For instance, when a South American client requested stainless steel sheet metal sets for heavy-duty machinery, we not only met but exceeded their expectations by providing materials certified under RoHS and CE, ensuring safe handling and long-term durability in harsh environments. In another case, an Eastern European client sourcing cold-drawn steel pipes for oil & gas applications required traceability and corrosion resistance. We leveraged our digital quality tracking system—implemented in 2020—to provide full production process visibility, from raw material batch to final inspection. This transparency allowed the client to audit every stage, reinforcing trust and enabling faster regulatory approvals. Furthermore, our surface treatment department, which includes zinc-nickel electroplating and anodizing, ensures enhanced protection against wear and salt spray exposure. These certifications are not just paperwork—they’re proof points of our operational excellence. By aligning with international standards, SP-MFG guarantees that every component we produce is safe, reliable, and ready for global deployment.

• Rigorous Quality Assurance Processes:

Quality is embedded into every step of our production cycle at SP-MFG. We employ a robust QA/QC system staffed by four dedicated inspectors who conduct real-time checks using state-of-the-art equipment such as Coordinate Measuring Machines (CMM), optical comparators, and surface roughness testers. From incoming material verification to final packaging, each part undergoes multiple inspection stages. A prime example of this diligence occurred during a large-scale automotive sensor housing project for a German OEM. The client demanded a tolerance of ±0.05mm and a salt spray resistance of 96 hours—critical for under-hood reliability. Our team executed CNC milling followed by zinc-nickel electroplating, then subjected each unit to CMM scanning and salt spray testing. Out of over 500,000 units produced, only 0.8% failed initial screening—resulting in a 99.2% on-time delivery rate and zero field failures reported in the first year post-launch. This level of consistency is made possible by our digital quality tracking system, which logs every measurement, machine setting, and operator action, enabling instant root cause analysis if deviations occur. Additionally, our DFM (Design for Manufacturability) reviews help clients avoid costly redesigns before production begins. For a U.S. robotics firm developing a new robotic arm joint, our engineers identified two potential stress points in the original CAD model and suggested minor geometry adjustments that improved structural integrity by 30% without increasing cost. These proactive measures reflect our philosophy: quality isn’t inspected in—it’s built in. With annual output valued at 30 million RMB and exports reaching 5–7 million USD, our quality systems are battle-tested and scalable, ensuring that every order, regardless of size, receives the same meticulous attention.

--- Global Reach and Customer Satisfaction ---

• Successful International Projects:

Since establishing export operations in 2018, SP-MFG has successfully served clients across North America, South America, Eastern Europe, and Southeast Asia, building a reputation for reliability and responsiveness. One of our most impactful projects was with a Bulgarian industrial equipment manufacturer requiring 3,000 stainless steel sheet metal sets for automated assembly lines. Despite tight deadlines and complex interlocking parts, we delivered the entire order within 18 days—thanks to our agile production planning and efficient workflow. The client praised our ability to manage last-minute design changes and provided feedback that led to a repeat order of 5,000 units. Another significant success story comes from Afghanistan, where we supplied 500 sets of cold-drawn steel pipes for water infrastructure projects. Given the remote location and logistical challenges, we coordinated directly with freight partners to ensure timely delivery via sea freight, while maintaining full documentation and customs compliance. The project was completed ahead of schedule, and the client commended our communication clarity and after-sales support. In addition, our recent expansion into the medical and aerospace sectors has yielded impressive results: in 2024 alone, revenue from these high-tech fields grew by 40%. We’ve partnered with several U.S. medical device firms to manufacture implant-grade titanium components with mirror-polished surfaces (Ra ≤ 0.1μm), meeting strict biocompatibility standards. Similarly, our aerospace clients now rely on us for 5-axis machined titanium parts used in satellite propulsion systems. These achievements underscore our ability to adapt to niche, high-demand markets while maintaining consistency and speed. With a factory floor area of 980 square meters and a workforce of 26 skilled professionals—including 3 R&D engineers—we combine agility with precision. Our one-stop service portal, launched in 2022, allows global clients to track orders in real time, further enhancing transparency and satisfaction. At SP-MFG, we don’t just deliver parts—we build lasting partnerships.

• Comprehensive After-Sales Support:

At SP-MFG, customer satisfaction doesn’t end at delivery. We stand behind every product with a comprehensive after-sales support system designed to resolve issues swiftly and maintain long-term trust. If a defect arises due to our production process, we guarantee remanufacturing at no additional cost—ensuring clients never bear the burden of our errors. This policy was put to the test during a bulk order of 10,000 automotive sensor housings for a Canadian auto supplier. Upon receiving the shipment, the client discovered a minor dimensional deviation in 12 units. Instead of waiting for a formal claim, our customer service team responded within 2 hours, initiated a full rework process, and shipped replacements within 72 hours—all at our expense. The client later shared that this swift resolution strengthened their confidence in SP-MFG, leading to a follow-up order of 50,000 units. Our digital platform also enables real-time issue reporting: clients can upload photos, videos, or inspection reports directly through the portal, triggering immediate investigation by our QA team. We’ve even developed a dedicated mobile app feature for urgent requests, allowing customers in remote regions like Eastern Europe and South America to communicate instantly via WhatsApp (+86 13509845535). Beyond problem-solving, we offer technical consultation, design optimization, and material recommendations—even after the order is complete. For example, a U.S. drone manufacturer contacted us months after delivery to request a revised version of their UAV frame with improved heat dissipation. We redesigned the part using aluminum alloy 6061-T6 and optimized cooling fins—all while keeping the same fit and finish. The updated version reduced thermal buildup by 25%, and the client credited SP-MFG for helping them win a major contract. This level of ongoing partnership reflects our core belief: true success lies not just in shipping products, but in growing alongside our clients. With a proven track record of 99.2% on-time delivery and continuous improvement, SP-MFG is more than a supplier—it’s a strategic ally in your manufacturing journey.
