AI-Powered supplier vetting

SummaryZhejiang Sanrock Supply Management Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory, offering mining machinery and related mechanical and electronic equipment. It reports strong export orientation, with 90% of total sales from exports, self-operated import/export rights, and five years of export experience. Customization is available across sample-based, design-based, full, minor, and flexible formats. However, the supplier is not identified as a professional technical supplier and does not provide 3D software design services. Evidence is insufficient for certification holding, financial credibility, production capacity, and customer cases. Service procedures for supplier approval, corrective actions, and complaint handling exist but lack written records; inventory, overseas warehouse, and overseas showroom capabilities are explicitly absent.

Product Q&A

Q:What are the main applications for this eccentric casing system?

It is suitable for drilling water wells, geothermal wells, short micropiles, medium mini-type grouting holes for building, dam, and harbor projects, as well as coal mining and quarry drilling.

The drill bit is made from high-quality Tungsten Carbide and High Manganese Steel, processed through casting, machining, and heat treatment.

Q:How does the swing-out reamer mechanism work?

During drilling, the reamer swings out to widen the pilot-hole for the casing tube. Once the required depth is reached, rotation is reversed to swing the reamer in, allowing the drill bit assembly to be pulled up through the casing.
