Qingdao Infinity Precision-Machinery Co., Ltd — Supplier
About Qingdao Infinity Precision-Machinery Co., Ltd - CNC Machines & Spare Parts Supplier in China
China, Qingdao is the location of Qingdao Infinity Precision-Machinery Co., Ltd, which currently lists five active products in its catalogue. The company’s top categories include CNC machines and spare parts, machined components, electric arresters, automobile gear boxes, and light & medium machinery. Each product entry on the platform is identified by a specific name, such as Alex, Shaft, Arrester, Gearbox and Differential housing, reflecting the breadth of its engineering output. The Gearbox entry is linked to HS code 8483.40 and specifies alloy‑steel gears with a cast‑iron or steel housing, indicating the material focus for that item.
The supplier’s catalogue does not provide HS codes for the other four items, but the product names place them within well‑defined HS chapters: CNC machines fall under chapter 84 (machine tools), machined components under chapter 84.70, electric arresters under chapter 85 (electrical equipment), and differential housings under chapter 84.71. By grouping the five products into these HS families, buyers can locate the appropriate customs tariffs and documentation requirements for each type. The active product count of five demonstrates a focused portfolio rather than a broad, unfocused inventory.
Product Range and Specialties of Qingdao Infinity Precision-Machinery Co., Ltd
The CNC Machines & Spare Parts segment listed by the supplier typically comprises machining centers with spindle speeds ranging from 6 000 to 12 000 rpm, positioning accuracy of ±0.01 mm, and tool change times under 5 seconds. Spare parts often include linear guides, ball screws and servo drives that meet ISO 230 and ISO 10791 tolerance classes. Machined components such as shafts are generally produced from carbon or alloy steel to ISO 683‑1 standards, with surface roughness Ra 0.8 µm common for bearing applications. Electric arresters are usually classified by voltage‑withstand levels (e.g., 6 kV, 15 kV) and must comply with IEC 61000‑4‑5 surge protection tests. Gearboxes listed under HS 8483.40 commonly feature gear ratios from 3:1 to 10:1, housing materials of alloy steel or cast iron, and gear tooth accuracy according to ISO 1328 (quality grades 6‑12).
Trade and Export Information - Qingdao Infinity Precision-Machinery Co., Ltd
China is a leading exporter of machine tools, electrical protection devices and automotive transmission components. Buyers in Europe, North America and Southeast Asia regularly import CNC equipment (HS 8456) and gearboxes (HS 8483) from Chinese manufacturers, often requiring CE marking, ISO 9001 quality‑management certification and, for electric arresters, IEC 61869‑1 compliance. Typical shipment sizes are 20‑foot or 40‑foot containers, with gearboxes packed in wooden crates and CNC units crated with vibration‑absorbing inserts. Customs clearance frequently involves a pre‑shipment inspection (PSI) and a declaration of material composition for alloy‑steel parts. The supplier’s target markets are not listed, so buyers should verify whether the exporter can meet destination‑specific regulations such as UL listing for the United States or EAC conformity for the Eurasian Economic Union.
Logistics for these categories usually follow FOB or CIF Incoterms, with loading on roll‑on/roll‑off vessels for larger machinery and containerised freight for smaller gearboxes and spare parts. Export documentation commonly includes a commercial invoice, packing list, certificate of origin, and test reports for electrical arresters. Importers should also be aware of anti‑dumping duties that may apply to certain high‑precision CNC machines originating from China.
Sourcing from Qingdao Infinity Precision-Machinery Co., Ltd - Buyer Guidance
When evaluating Qingdao Infinity Precision-Machinery Co., Ltd, buyers should request the latest CE test report for any electrical arresters and an IEC‑type performance certificate for surge protection levels. For gearboxes, a material test certificate confirming alloy‑steel composition and a gear‑accuracy report (ISO 1328) are standard due‑diligence items. Machined components such as shafts should be accompanied by a dimensional inspection report and a hardness certification (Rockwell or Brinell) matching the specified steel grade. Sample orders are advisable for the “Alex” CNC model to verify spindle power, tool changer reliability and software compatibility before committing to larger volumes.
Typical minimum order quantities (MOQ) for CNC machines and gearboxes range from one unit to a small batch of five, depending on the customization level. Lead times in China for standard models are usually 30‑45 days after receipt of a pro‑forma invoice, extending to 60‑90 days for custom‑engineered gearboxes or differential housings. Buyers should confirm container loading plans, verify that packaging meets ISPM 15 phytosanitary standards for wooden pallets, and ensure that any required pre‑shipment inspection is scheduled well before the intended shipment date.
