QUALITY CONTROL

Miningwell has a complete QC process, which is divided into the following four parts:
1. Real-time inspection of production: To ensure that the production sequence of the product obeys the specifications, and the parts are not damaged.
2. Full factory inspection: Every equipment and drilling tool from Miningwell will undergo a strict factory inspection.
3. Loading safety inspection: To ensure the safety of the goods in the container.
4. Visit customers regularly to do after-sales service and regular maintenance for exported equipment.

After loadng, every machines must be strapped and fixed by a professional.

Before leaving the factory, each machine undergoes strict inspections.

Efficient loading team.

The engineer went abroad to repair the air compressor.
