Product Quality and Safety Meetings
Product quality and safety meetings, led by the Quality Assurance Department, are held once a month as a way to prevent complaints and the reoccurrence of product-related accidents. The meetings are attended by section managers from the manufacturing, development, installation, design and procurement departments.
In addition to discussions related to improving or altering product specifications, since fiscal 2018 talks have focused on perpetual topics that aim to further enhance quality.
Strengthening Installation Quality
We provide arc welding training with the aim of increasing welding skills as an initiative to enhance installation quality. (FY2019:81 participants).
- We have secured a consistent level of quality at our component suppliers by conducting on-site surveys, quality diagnostics sessions and process patrols at core component suppliers
- We conduct on-site quality audits at core door subcontractors with the aim of ensuring compliance with quality-related rules
- Trained and deployed plant inspectors
- Trained and deployed internal plant auditors
- Created standard drawings as a basis for production specifications
Initiatives at Overseas Subsidiaries
ODC works to ensure quality by employing quality managers that provide training and guidance to pre-shipment inspectors and by implementing other measures related to quality improvements.
- At NF Group, the on-time delivery rate, a quality ratio, as well as productivity, safety and inventory ratios have been set as key performance indicators (KPIs) that are common throughout the Group. Led by the person in charge of overall quality control, meetings are held every month with management, development and production managers, and factory directors with the aim of improving quality and safety.
At Asian subsidiaries, meetings of the Quality Council and study sessions are held regularly, examples of improvements following mistakes on work diagrams are shared and patrols and guidance for partner companies are conducted in order to achieve quality objectives.
At Novoferm (Shanghai), three specialized quality inspectors perform checks on dimensions and the external appearance of fasteners and coatings. Only those fittings that have received a label with the name of the inspector are shipped out.
In 2019, people responsible for manufacturing at Novoferm (Shanghai), Vina-Sanwa, and PT Sanwamas toured the production facilities and viewed the management system at the NF Group’s Schievano Plant (Italy) and Riexinger Plant (Germany). These plants use automation extensively. The goal is to promote reforms in door manufacturing in Asia. Through this sharing of know-how and regular interactions of personnel globally, we are improving productivity and increasing product quality around the world.
Providing High Quality by Enhancing Safety and Productivity
Sanwa Shutter Corporation is taking steps to save labor during installation through such means as an integrated shutter production method covering from advance assembly of heavy-duty shutter shafts and slats at a plant to delivery, as well as a non-fired production method in which a door is mounted without welding. This in turn increases safety and productivity at installation sites and ensures high quality through efficient operations.
Test Center with latest equipment has acquired ISO/ICE17025 certification. In addition to evaluating the quality, performance and safety of Sanwa Group products and products procured both inside and outside Japan, the Test Center evaluates manufacturing technologies and conducts testing on behalf of external parties.
Supporting Product Development with High-Quality Testing
The Test Center assesses quality, performance and safety and evaluates manufacturing technologies for the Sanwa Group's products as well as products procured in Japan and overseas. We are able to make timely development and improvement of products based upon requests from customers as our products can be tested in our own facility. We will continue our efforts to raise the level of testing quality to contribute to improved quality in product development and manufacturing.
Overview of Main Facilities
Fire Protection and Fire Resistance Test Facility
With one of the world's largest refractory furnaces, the Test Center conducts fireproof performance tests (preliminary tests for certification and research tests) for fireproof equipment and specified fireproof equipment. Smoke generated in fire resistance tests is discharged after passing through a secondary incinerator to reduce environmental impact.
Combined Environmental Reliability Test Facility
This facility features a large open space and numerous functions to enable overall testing of products. It is used for conducting operating tests in environments with various temperature and humidity combinations; insulation tests; operating tests in snowy conditions using a snow maker; sound insulation tests; and testing of sound generated.
Large- and Small-scale Dynamic Wind Load Test Facility
This facility tests wind pressure resistance, airtightness and watertightness.
Wind and Rain Test Facility
This facility is used for observing behavior characteristics (including pulsation) in wind and rain.
Implementation of the Periodic Inspection Reporting System for Fire Prevention Equipment
The periodic inspection reporting system for fire prevention equipment, a partial revision of the Building Standards Act, went into effect in June 2016. The purpose of this system is to prevent accidents occurring in cases of fire caused by malfunctioning fire prevention systems. Nationally qualified inspectors inspect the fire prevention system of a designated building and report the results to the local government.
In response, primarily at Sanwa Shutter Corporation, we have implemented training to secure a base of qualified inspectors who can conduct inspections and are promoting the acquisition of ﬁre prevention equipment inspection certiﬁcation.
Development of Safe, Secure Service Providers: Fire Prevention Equipment Periodic Inspection Skills Contest Held
Sanwa Shutter Corporation held a contest in May 2019 that brought together top-class installers from each region to pit their skills against each other. The top installers competed on all 22 technical items, including preparation and inspection work as well as manners. The main purpose is to work to improve the technical level and manners of installers, but one of the contest’s other aims is to record the work processes of the best people for training purposes, share those processes with installers across the country, and standardize them.
In the years to come, we will continue to provide social safety, security and convenience by improving the maintenance inspection and repair techniques of each and every one of our installers and building relationships of trust with our customers.
We have operated the Maintenance Training Center since 2017. We are focused on knowledge acquisition related to the periodic inspection reporting system for fire prevention equipment and development of human resources. As a leader in the industry, we bear a responsibility for safety and security. That is why we aim for the further pursuit of "safety, security and convenience" in order to protect human life and the infrastructure of society from disasters, including fire.
