More detailed self-inspection system
We at WANTS consider quality control and quality management to be more important than technological innovation. Our unique self-inspection and sequential inspection system, which has been redesigned with more detail and precision than conventional inspection systems, can guarantee high satisfaction with our products.
Our relationship with our customers is our top priority, and we operate a company-wide inspection system with a defect rate of ZERO (%).
Quality Control Process
Detailed independent inspections are conducted for all processes and sequential inspections are conducted between each process, already meeting the zero-defect rate at the shipping stage.
-
Kneading
After 5-point/1 lot inspection, if the density rate per point is more than 99.5%, the product is sent to the injection molding process.
Measuring equipment: Density meter 1/1000g -
Injection
Only parts with a conformance of 99.9% or higher through 1 shot weight and dimensional inspections of injection molded parts in two (2) hour increments are sent through the dewaxing process.
Measuring equipment: balancing scales, vernier, tool microscope -
De-Binding
After degreasing and weight inspection using a balance scale of 1/10000g along with visual inspection, only parts with a density of 9 points/1 lot (1pcs per each point) with a conformance of 95% or more are sent for the sintering process.
Measuring equipment: balance scale 1/10000gThe dewaxing path is divided into a total of 9 points per lot, and each point is used as a basis for comparing the dewaxing rate.
(The above process is equally applicable to both degreasing and sintering.) -
Sintering
At the stage of inspecting the density of the final sintered parts, the density rate of 9point/1lot (3pcs per point) and 99.9% conformity of dimensional inspection using a micrometer are satisfied to be sent to the vision inspection stage.
Measuring equipment: micrometer (tool microscope), balance scale 1/10000g -
Vision
The vision inspection stage for full dimensional inspection is based on satisfying 100% conformance of the total vision to CTQ point for final shipment.
