From the beginning, the project manager will try to deeply understand your quality requirements, and customize a quality control system that helps our production achieve your product quality instructions.
ISO 9001:2008 certified We utilizes ongoing employee training, automation, continuous process improvement and innovation to maximize the quality, reliability, and cost-effectiveness of your components.
Parts are carefully examined throughout the production process at multiple quality control checkpoints and all shipments are thoroughly tested and inspected before they are released to your facility. As a result, our team has been able to consistently maintain a nearly 0% external part reject rate that has enabled many of our customers to eliminate the costly and time eroding process of inbound part inspection.
We have a full-time AWS certified inspector and each of our welders is qualified to one or more of the following specifications and/or codes:
AWS D1.1 – Structural Welding Code – Steel
AWS D1.2 – Structural Welding Code – Aluminum
AWS D1.3 – Structural Welding Code – Sheet Steel
AWS D1.6 – Structural Welding Code – Stainless Steel
AWS D14.3 – Specification for Welding Earthmoving Construction and Agricultural Equipment
AWS D15.1 – Railroad Welding Specification for Cars and Locomotives
EN 287-1 – Qualification Test of Welders – Fusion welding – Part 1: Steels
DIN EN 15085 – Railway Applications. Welding of Railway Vehicles and Components.
Customer specific welder qualifications.
Just-In-Time Deliveries We realize that any delay to a just-in-time schedule is a critical delay. As a supplier, we have successfully implemented one of the most ambitious quality improvement programs in the industry to ensure that your production schedules are met. Our system affords flexible scheduling options and instant real-time order status.
Quality Control Testing
Depending on the customer’s requirements QC inspections are carried out in any of the following stages:
- Pre-manufacturing evaluation:
If the supplier is new to us we carry out a pre-order evaluation to ensure that the supplier is capable of producing the quality required. If the supplier is already known to us we may carry out a further evaluation if the product to be manufactured is not covered by a previous evaluation.
- During production:
Depending on the product(s), requirements and/or instructions we may carry out QC inspections during production – specially where different components are being produced and sub-assembled.
- Prior to shipment:
Our main thrust of QC happens after product has been manufactured. ChinaSavv’s QC team will inspect either sample quantities or complete production depending on the customer’s requirements.
- Sample sizes:
QC Levels and sample sizes depend on three criteria:
Value of product
Complexity of product
Typically,we works on 3 QC levels: Standard, Enlarged and Total.
Most of the time we apply our Standard QC plan. This specifies the number of permissible Critical (none), Major and Minor defects in a given sample. If more than the permissible defects are found in the sample our QC staff, then, either reject the entire batch or revert to a Total inspection of all units being checked.
The Enlarged QC Plan is similar to the Standard Plan but is much more stringent in the number of permissible minor defects and a greater sample size. This is applied generally to high value or complex products.
The Total QC Plan is a check on all parts being manufactured and or shipped.
Sample sizes and defect limits are available to customers on request.
All QC checks are documented and are available to customers on request.
