Wave spring has its unique advantage of
saving space, which can replace coil Springs. Wave spring also decreases spring
cavity by reducing spring operating height. It saves cost by reducing both
component size and material used in production.
Wave spring works as a force loading
device. It takes up gap and compensate for dimensional changes within the
assembled device. Almost any range of forces can be achieved by gradually or
suddenly changing loading force to preset working length. So a precise spring
ratio can be realized when loading force and deflection change in proportion.
SEALMANN introduced advanced equipments
from overseas used specifically for wave spring making and pre-tempered cold
rolling formed flat wire is used to produce wave springs through continuous
winding process, which possesses many advantages over products made from die
stamping process.
`SEALMANN` wave spring as a force loading
component can effectively compensate for dimensional deviations in assembly and
it can meet in different static or dynamic applications. There are mainly three
types of wave springs, i.e. single-layer wave spring, multi-layer standard wave
spring and multi-layer stacked wave spring, and they are widely used in
applications such as hydraulic and pneumatic, machinery, gear drive,
automobile, aerospace and petrochemicals etc.

The three standards were separately compiled by the Security and Police Electronic Product Quality Inspection Center of the Ministry of Public Security and Beijing Blueton Shi'an Information Consulting Co., Ltd.
The "Large and Medium-sized Shopping Malls and Supermarkets, Public Security Prevention Standards" was drafted by the Basic Work Brigade of the Municipal Public Security Bureau's Internal Protection Bureau and Beijing Blue Shield Shi'an Information Consulting Co., Ltd. It has made basic requirements and regulations for the air defense, physical defense, technical defense, and management of large and medium-sized shopping malls and supermarket public security systems in Beijing.
It is understood that the three standards make up for the city's large and medium-sized shopping malls, supermarkets and public security system construction, management; safety precautions project supervision; safety inspection system operation in the detection of three aspects of the standard blank.
The reporter learned from the Beijing Security Association that from October 14 to 15, the Beijing Municipal Bureau of Quality and Technical Supervision and the Municipal Public Security Bureau Science and Technology Division organized a two-day standard final review meeting. The three local standards such as “Standards for Public Security Systems for Large and Medium-sized Shopping Malls and Supermarkets,†“Safety and Precautionary Measures for Project Supervision,†and “Safety and Preventive Engineering System Testing Regulations†passed the final review of the experts.
