Why Buyers Choose TONNY

Why Importers Machine with TONNY

We are a machining factory, not a trading company — your parts are made by our own machines, inspected by our own QC, and shipped by our own export team.

Drawing-to-Part Service

STEP, IGES, STL, PDF or even a hand sketch — our engineers turn your file into finished parts and give DFM feedback before we cut.

One-Stop Machining

Milling, turning, 5-axis, EDM, surface finishing, assembly and packaging under one roof — fewer suppliers, fewer handoffs, fewer mistakes.

Quality You Can Verify

CMM inspection reports, material certificates and first-article reports with every order. If we say ±0.01 mm, it is ±0.01 mm.

Transparent Export Pricing

Clear piece pricing with no hidden tooling surprises. EXW, FOB, CIF or DDP — we handle packing, documents and shipping.

Fast, Direct Communication

Engineers answer on WhatsApp and email — English, Spanish and Russian support. Quote in 24 hours, honest advice always.

NDA & IP Protection

We sign NDAs and protect your designs. Your drawings, molds and programs stay yours — never shared, never copied.
