Choosing the right precision manufacturing process can save your company millions annually. Yujiaxin Tech has shown this across 2,000+ projects over the past 15 years.
When you need to mass-produce precision metal parts, process selection often determines whether a project succeeds or stalls. Will Metal Injection Molding (MIM) work for your geometry? Can powder metallurgy meet your tolerance requirements? What's the precision ceiling for gear hobbing? A wrong process choice can add six months to your timeline and multiply costs several times over.
Yujiaxin Tech is a Tier 1 precision manufacturer with 15 years of expertise, serving 2,000+ clients across new energy vehicles, medical devices, consumer electronics, and industrial automation. We operate 5 core precision manufacturing processes: Metal Injection Molding (MIM), Powder Metallurgy (PM), Investment Casting, CNC Precision Machining, and Gear Hobbing. These run on 70+ imported machines and 20+ technology patents.
Below, we walk through 4 verified precision manufacturing case studies that show how each process solves real manufacturing challenges.
Key Takeaways
- MIM + CNC finishing reduces new energy vehicle parts cost by 40-77%, with material utilization exceeding 95% and monthly capacity reaching 1 million units
- MIM + Investment Casting hybrid process delivers 60% cost savings on medical parts with a yield rate above 98% and tensile strength exceeding 480MPa
- Powder Metallurgy pressing achieves 0.3mm ultra-thin walls on consumer electronics parts, with defect rates below 0.3%
- Gear Hobbing + Powder Metallurgy combination extends transmission system service life by 3x with ISO Grade 8 gear accuracy

In early 2024, a leading domestic NEV Tier 1 supplier approached us with a critical challenge. Their e-drive system sensor bracket featured complex geometry with multi-angle irregular holes and thin-wall features. Using conventional CNC machining, the per-unit cost hit ¥28 with a batch yield of just 82%. Their target was clear: annual demand of over 12 million units required unit cost below ¥10.
Yujiaxin Tech's engineering team conducted a comprehensive Design for Manufacturing (DFM) analysis. After evaluating multiple process routes, we chose a Metal Injection Molding (MIM) + CNC finishing hybrid approach:
1. MIM for near-net shaping, forming over 95% of the part's geometric features in a single step 2. Precision CNC finishing on critical mating surfaces to achieve tolerance control of ±0.02mm 3. Proprietary feedstock formulation optimized for controlled sintering shrinkage
The entire mold design and process tuning cycle took 45 days, with first-pass approval from T0 sample to production qualification.
| Metric | Conventional CNC | Yujiaxin MIM Solution |
|---|---|---|
| Unit Cost | ¥28 | ¥6.5-16.8 |
| Material Utilization | ~35% | >95% |
| Yield Rate | 82% | 97.5% |
| Monthly Capacity | 80,000 pcs | 1,000,000 pcs |
*"After switching to MIM, our unit cost dropped by over 70%. The capacity bottleneck was completely eliminated."* — Client Procurement Director
This precision manufacturing case study validates Yujiaxin Tech's precision engineering expertise in high-volume production of complex-shaped parts. Cost reduction of 40-77% means real savings on the bottom line.

A Shenzhen-based medical device company specializing in minimally invasive surgical instruments needed mass production of a high-frequency electrosurgical knife handle core component. The material requirements were demanding: medical-grade 316L stainless steel, density exceeding 7.5g/cm³, and tensile strength of at least 480MPa. The part also had internal cooling channels just 0.8mm in diameter, which conventional machining can barely produce.
Yujiaxin's engineering team combined MIM + Investment Casting to create a differentiated process route:
Medical parts demand uncompromising quality. After six months of process validation and production ramp-up, this precision manufacturing success story delivered clear results:
*"Yujiaxin's process solution cut our product cost in half, and the quality consistency exceeded our expectations."* — Client R&D Director
This case shows that medical-grade precision parts at scale require hybrid process routes to deliver both performance and cost goals.

In late 2024, a global Top 5 consumer electronics brand hit a bottleneck in the hinge design for their next-gen TWS earbuds. They needed a precision hinge structural part just 0.3mm thick, in 316L stainless steel, with mating surface tolerance of ±0.015mm. Multiple supplier quotes showed yield rates below 70%, unable to meet the 50,000-unit monthly demand.
Yujiaxin's technical team proposed a Powder Metallurgy pressing + precision CNC machining combination process:
1. Ultra-fine powder (particle size <10μm) with specialized mold pressing for 0.3mm thin-wall one-shot forming 2. Vacuum sintering followed by 5-axis CNC finishing on critical mating surfaces 3. Full automated vision inspection covering every single part
After three months of process optimization and pilot production, the project reached stable mass production:
*"We asked our entire supply chain about 0.3mm wall thickness with ±0.015mm tolerance. Only Yujiaxin passed qualification on the first attempt."* — Client Structural Engineer
This precision engineering client project shows powder metallurgy can handle geometries and costs that conventional machining can't. For miniaturized, high-accuracy structural parts, PM is often the only practical route.

A Suzhou-based industrial robot core component manufacturer was developing a high-precision gear transmission system for their next-generation RV reducers. Their original all-machining approach delivered gear accuracy of only ISO Grade 9, with transmission efficiency around 85% and gear service life of approximately 6,000 hours. The client wanted efficiency above 90% and service life extended to 18,000 hours, all without significant cost increases.
Yujiaxin proposed an innovative route combining Powder Metallurgy gear blank forming + precision Gear Hobbing:
This precision manufacturing example exceeded expectations:
*"After transmission efficiency exceeded 92%, our entire system passed performance validation on the first attempt. This single improvement directly determined our product launch timeline."* — Client Project Manager
Gear hobbing plus powder metallurgy lets you balance accuracy, efficiency, and cost in a way conventional machining can't.

After reviewing these 4 precision manufacturing case studies, you might ask: what makes Yujiaxin different from other precision parts suppliers?
From MIM to powder metallurgy, investment casting to CNC machining and gear hobbing, we offer our complete 5-process manufacturing matrix. No more coordinating between multiple vendors. One point of contact, full end-to-end management from DFM analysis to production delivery.
For non-standard parts manufacturing cases, mold cycles typically run 25-45 days, with an average of just 2-3 iterations from T0 sample to production approval. Standard product lead times are 20% shorter than the industry average.
