WHAT IS PYRO-PROPELLING INDUSTRY?
Pyro-Propelling System, is the product to use Pyrotechnic or High Pressure Gas Storage to provide Propelling Energy or Fillant. Normally, the products involved in automotive industry are inflators, hoodlifters, pyrofuse and igniter.
Inflators are the units offering gas for Airbag during deployment. By the working type, inflator could be categorized as pyrotechnic type, hybrid type and cold gas type.
The pyrotechnic inflators are transfering solid to gas by chemical reaction. Cold gas inflators are fully mechanical, using high pressure storage.
As inflators are safety relative parts, and one-time function, it cannot use result testing. The manufacturing process control and inflator storage would be key for the inflator prouction.
The process used in inflators' production are Crimping, Laser Welding, Precise Pressing, Propellant filling, label applying, friction welding, high pressure gas filling, resistance welding, Helium Leakage Check, Eletrical Characteristics Testing
HOW IS AUTOMATION IN PYRO-PROPELLING INDUSTRY?
ROBIC MATERIAL HANDLING:
No operator involved manufacturing process, all the motions fulfilled by the mechanical structure and robot, with work piece carrier or rotary table. The material supplied with bowl feeder or part pallets
HIGH QUALITY CONTROL:
Every step of assembling process has process control tracking, the raw material before assembling into product, has critical features checking.
EXPLOSION PROOF
As the propellant are pyrotechnic parts, the equipment need to be built with explosion proof design.
