CHANGING PERCEPTIONS

We Do it Differently

High Precision ±0.005mm

We hold tight tolerances down to 0.005mm on critical features. In-house CMM inspection ensures every part meets your spec — no tolerance drift.

100% IP Protection

We sign NDAs for all custom projects. Your drawings and designs are kept strictly confidential and never shared with third parties.

Consistent Batch Quality

Standardized SOPs and process control guarantee zero batch-to-batch variation — whether you order 10 or 10,000 parts.

Clear Bilingual Communication

English-speaking engineers and sales team respond within 12 hours. We confirm every detail before production to avoid miscommunication.

On‑Time Delivery Guarantee

Digital production scheduling + weekly progress updates keep your project on track. We ship as promised.

Flexible Order Quantities

No MOQ — take 1 piece for prototyping, 100 for pilot run, or 10,000+ for mass production. One partner from start to scale.

What Our Customers Say

"They delivered our custom 6061 aluminum automation brackets 2 days early, all parts were within 0.01mm tolerance. Communication was seamless even with the time difference."

Marco R.

Purchasing Manager, Italy 🇮🇹

"We have worked with Metron for 3 batches of medical device parts, their quality is always consistent. The inspection reports they provide save us a lot of incoming inspection time. Highly recommend."

Steven W.

Engineering Lead, Germany 🇩🇪

"We switched from a local supplier to Metron for our robotic arm components. They handled the complex PEEK material perfectly and delivered 50 pcs in just 6 days. The flexibility on small batch runs is a game-changer for our R&D team."

James T.

Engineering Manager, USA 🇺🇸

"This was our first time sourcing critical titanium parts from China. Metron provided full material traceability and passed our strict NDT inspection without any issues. A very reliable partner for aerospace-grade components."

David K.

Procurement Director, UK 🇬🇧

"We have used them for over 20 different part numbers in the past year. Turnaround is always fast, and the DFM suggestions they provide upfront genuinely save us money on tooling. We treat them as an extension of our own supply chain."

CNC Milling

The backbone of precision part production, our 3‑, 4‑, and 5‑axis milling centers handle complex geometries with ease. Equipped with high‑speed spindles and advanced tooling, we machine everything from simple brackets to intricate housings. Tight tolerances down to ±0.005mm are achieved across aluminum, stainless steel, titanium, and engineering plastics. Whether you need one-off prototypes or high‑volume runs, our milling cells are optimized for repeatability and efficiency.

CNC Turning

For cylindrical and rotational parts, our CNC lathes deliver exceptional roundness and surface finish. We produce shafts, bushings, pins, and threaded components with diameters ranging from a few millimeters to large‑diameter parts. Live tooling options allow for milling and drilling in a single setup, reducing lead times and improving part accuracy. Our turning capabilities cover all standard metals and plastics, with tolerances held to ±0.01mm on critical dimensions.

Surface Grinding

When your design calls for ultra‑flat surfaces, precise thickness control, or fine surface finishes, our precision grinding machines deliver. We offer both surface and cylindrical grinding, achieving surface roughness down to Ra 0.4µm. This process is ideal for mold bases, fixture plates, and mating components that require perfect flatness and parallelism. Combined with our inspection equipment, every ground part is verified to meet your geometric tolerances.

Anodizing

To enhance corrosion resistance and wear properties, we provide Type II and Type III hard coat anodizing for aluminum parts. Our anodizing line produces uniform, durable coatings in clear, black, and various colors. The process also improves surface hardness, making it suitable for sliding or high‑friction applications. We strictly control bath chemistry and thickness to ensure consistent appearance and performance across batches.

Plating

For parts that require superior conductivity, solderability, or extra corrosion protection, we offer electroplating services including zinc, nickel, silver, and tin plating. Our plating processes adhere to industry standards, with proper thickness and adhesion testing. We handle both rack and barrel plating, accommodating small precision components as well as larger assemblies. All plating is performed with environmentally compliant chemistries.

Polishing

When aesthetics matter, our polishing and buffing services deliver mirror‑like finishes on stainless steel, aluminum, and other metals. We use progressive abrasive techniques to remove tool marks and achieve desired surface gloss levels — from satin to bright mirror. Polishing is often combined with passivation for stainless steel parts, ensuring both visual appeal and corrosion resistance. Ideal for visible components in medical, consumer, and automotive applications.
