Ryder Electronics established in Shenzhen on July 18, 2005, mainly
in the business of battery packs. In 2009 the company passed
ISO9001 and improved the product quality standard to fulfill the
high-end requirements from our customers.
In 2012, Ryder Electronics moved to a new facility and expend the
production capacity, the Productivity improved nearly 10 times than
before.
In 2013, Ryder Electronics imported ERP (SAP) system to supervise
order execution process.
In 2017, Ryder Electronics expanded the SMT, imported high-speed
patch machine from Germany.
Until now the factory grows into a modern enterprise which
integrated injection molding, PCB designing, SMT and battery pack
assembling services.
In 2018 the company passed ISO14001certification, introduced
automated battery production line to further improve the production
quality and capacity.
