        11: plastics welding has which methods?

        答: plastics welding methods has ultra- 声波 welding, scratch welding, welding, hot sheet/plate welding, hot gas welding and welding.

        12: plastics light welding process has advantages?

        答: and plastics welding process versus ratio, light welding tool has welding strong/high degree high, add hot and cooling speed degree fast, hot effect/influence small, welding force and deformation very small;

         non processing, for parts generate outer force function, can welding difficult 于接触 部位;

         welding process stability, surface and inner in quality good, property can high;

        激 light in true 空, gas and certain types gas ring in can 施焊, through or for light transparent material welding and other more advantages.

        13: plastics light welding need additives 吗?

        答: has welding need use to additives, ratio 如炭黑 absorption agent, is for/regarding plastics welding medical grade plastics welding need absorption agent additives.

        14: plastics light welding absorption agent add methods has which?

        答: is toward welding material in absorption agent;二 is toward plastics parts welding surface absorption agent;

        三 is in block welding plastics parts 接触处 spray coating upper or printing upper absorption agent.

        15: plastics light welding main applications in which 方?

        答: main/primary use in automotive industry, home appliances industry, medical industry and electronics electrical appliances industry and other and other.

         ratio automotive industry automotive table/sheet sheet/plate, 车灯, system plastics parts, new can automotive battery, EPB electronics system plastics parts and other;

         medical industry micro 控流部 parts, anti product, Phonak retardant device and other;
