Vintech Ltd offers Quality Assurance and Quality Control Services to clients across different industries. Our services help reduce risk and ensure that purchasers receive the products and services conforming to their specifications and relevant technical standards.

At Vintech Ltd, we assign a dedicated Project Co-ordinator to work closely with the client to identify the exact level of service required. Based on the client’s requirement, the co-ordinator identifies a candidate with the right level of technical expertise and experience. The Project Co-ordinator then assigns the best-qualified inspector for the specific assignment.

The Project Co-ordinator will provide a detailed assignment to the field inspector, which includes clear instructions identifying exactly what activities are required, details of any specific client requirements and expectations.

We perform Inspection, Expediting and Vendor Assessment QA/QC services.

Inspection Assignments:

At Vintech Ltd, we perform surveillance inspections, final pre-shipment inspections and resident inspections.

Surveillance inspections: We perform surveillance inspections at various stages of manufacturing according to client’s instructions and approved Quality Control Plan.

Final pre-shipment inspection: We carry out final inspection prior to shipment to verify “Fit for Purpose” and dispatch to project site.

Resident inspection: When continuous monitoring is required, we provide a Resident Inspector to verify compliance to all client and statutory controlling specifications. Procedures, equipment, qualifications and certifications are verified for compliance. Manufacturing and inspection processes are monitored during the various stages of production and testing.
