Pyrotechnic Inter Stage Linear Shape Charge Assembly

Pyroalliance designs and manufactures specific Inter-Stage Linear Shape Charge Assemblies (ISLSCA). These products, machined from a linear profile with an initiation port at each end, are combined to build a complete Inter-Stage Separation System. Incorporating pyrotechnic cutting cords into those ISLSCA, Pyroalliance offers a robust solution, securing a highly reliable inter-stage separation function. More generally, Pyroalliance delivers complete pyrotechnic chains adapted to its customers’ needs. They are designed and manufactured under Pyroalliance design authority.
