Seed has a number of experienced experts in the materials field to conduct professional analysis of physical and chemical properties of materials.

3  Quality engineering

Seed formed a team of quality engineers to track and control the quality of products. Each customer is assigned a professional quality engineer to conduct all-round control from the aspects of early order evaluation, customer quality specification review, quality standard establishment, handling of abnormal issues in the production process, and follow-up shipment quality.

4  Quality inspection

Seed facilitates a rigorous quality inspection system on a four-stage model that ensures a complete cycle of inspections to eliminate any escapes of quality.  For the production and processing control process, we have established incoming inspection (IQC), in-process inspection (IPQC), final inspection (FQC), and outbound inspection (OQC). This strategy strictly controls the quality of raw materials, implements proper parameters for each process, establishes the inspection process, and is conducted under orderly control in  accordance to inspection specifications and customer requirements to ensure that the quality of products meets the customer’s needs. 

 4.1 IQC Inspection Process


4.2 First Article Inspection(FAI)and Process Inspection(IPQC)Process


4.3 Final Quality Control(FQC),Outgoing Quality Control(OQC)Process


5  Nondestructive Examination(NDE)

Seed is equipped and capable of performing UT,MT,PT inspections professionally trained personnel who are certificated to NDE II and NDE III in accordance with ISO9712, ASNT and other standard qualificiations.
