High Flexural Strength Mould parts / Customization BMC / DMC mould parts with high strength
Product Name:High Temperature of deflection Mould parts
SMC/DMC/BMC molded partsis made of glass fibre which is Immersion in unsaturated polyester and Vinyl resin,It is a thermosetting material which is made by heat pressing.
1. Compared to similar methods, SMC benefits from a very high volume production ability, excellent part reproducibility, it is cost effective as low labor requirements per production level is very good and industry scrap is reduced substantially.
2. Weight reduction, due to lower dimensional requirements and because of the ability to consolidate many parts into one, is also advantageous.
3. The level of flexibility also exceeds many counterpart processes.

High Flexural Strength Mould parts used in Switch cabinet
Switch cabinet is an electrical device , the exterior lines of switch cabinet enter in main control switch in the cabinet first, then enter the control switch, each branch is set according to its need.The main function of the switch cabinet is make the opening&closing ,control&protect electric equipment in the process of power generation, power transmission, distribution and power conversion.The components in the switch cabinet consist of circuit breaker, isolating switch, load switch, operating mechanism, transformer and protective device of insulation component.The insulation components in switch cabinet are supporting, bearing and isolating ,so the insulation materials are required to be: higher electrical strength, higher mechanical strength, stronger arc resistance and so on. The commonly materials used in switch cabinet are UPGM203 laminated sheet
Our products are mainly used as making of phase & end barriers,contact terminal support,terminal plate,insulating supports,bus bar supports and mounting panels.
