Quality Assurance
“Promoting manufacturing that both customers and NISSEI prosper” is NISSEI’s quality assurance policy. NISSEI promotes rigorous quality assurance practices throughout their manufacturing process in order to meet the specifications, quality, and safety that customers are expecting.
Quality Assurance Practices
NISSEI enforces three categories of quality assurance practices through required inspections and management systems.
-
Enforcing quality assurance practices from product design to mass production.
Design review and verification at each process.
-
Enforcing quality assurance practices as daily routines during production.
Inspection at each process and nonconformity/corrective actions.
-
Enforcing quality assurance practice by improving products.
Responding to customer claims and implementing preventive measures.
Quality Management System (QMS)
NISSEI’s Quality Management System (QMS) is documented in their Quality Management Regulations, and quality reviews are conducted by internal and external organizations every fiscal year. NISSEI applies the results of these reviews to enhance product qualities and continuously improves the QMS, directed by the chief quality officers of applicable departments. In addition, NISSEI’s head office, three production subsidiaries (NISSEI HOMMA MACHINERY CO., LTD., NISSEI PLASTIC MACHINERY (TAICANG) CO., LTD., and NISSEI PLASTIC MACHINERY (THAILAND) CO., LTD.), and subsidiary company (NEGRI BOSSI S.P.A.) have acquired ISO 9001:2015 (the international standard for quality management systems) certifications.
QMS Management Reviews
Annual QMS management reviews are conducted to check the accuracy and effectiveness of NISSEI’s quality management system. The chief quality officers of applicable departments apply the results of the reviews to improve the QMS and incorporate their findings when they formulate quality targets for their departments for the following fiscal year.
Quality Improvement Initiatives
Quality improvement meetings are held every month. The topics include the following:
- Improvement of faulty parts and components
- Status updates of ongoing improvement projects and its preventive measures
- Information share between departments and subsidiaries.
During Quality Month in November every year, NISSEI conducts educational activities on quality improvement for both in-house and outside entities to promote the awareness of quality improvement practices.
Response to Product Nonconformity
When issues with the products are reported, the sales department serves as the point of contact, and the department in charge of the defective component takes the lead in quickly responding to and resolving the issue.
