The top cover of the plastic transparent socket box is PC polycarbonate, and the base is made of ABS plastic injection molding. Power socket has one or more circuit wiring can be inserted into the seat, through it can be inserted into a variety of wiring, easy to connect with other circuits. Industrial plug is suitable for industry, generally divided into 3 core, 4 core, 5 core, etc., current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., protection grade can be divided into IP44, IP67 these two, for these are more conventional. In general, it is used with industrial sockets and industrial connectors. A switch is arranged between the weatherproof socket resistance and the electromagnetic switch, the fuse and the electromagnetic switch is connected with the power line, the power line is arranged on the electromagnetic switch normally open switch, the electromagnetic switch normally open switch is connected with the jack. Abs plastic injection mold process conditions;




Injection temperature :180 ~ 270℃(applicable processing temperature range 220 ~ 250); (Plug injection machine, furnace temperature kept at 180 ~ 230; Screw machine, furnace temperature kept at 160 ~ 220)




Mold temperature: the general mold temperature is 65~85℃.




Process conditions of ABS plastic injection molding:




Injection temperature :180 ~ 270℃(applicable processing temperature range 220 ~ 250); (Plug injection machine, furnace temperature kept at 180 ~ 230; Screw machine, furnace temperature kept at 160 ~ 220)




Mold temperature: General mold temperature 65 * 85 ° C, production of parts with large projection area, fixed mold temperature is required 70 * 80, dynamic mold temperature is required 50 * 60. Mold temperature will affect the surface finish of plastic parts, the lower the temperature, the lower the surface finish.




Injection working pressure: high injection pressure is adopted.




Injection speed: medium and high speed.




Material quantity control: each injection volume is only 75% of the standard injection volume




The engineering plastics have excellent comprehensive properties, excellent impact strength, good dimensional stability, electrical properties, wear resistance, chemical resistance, dyeing, good molding and machining. Abdominal muscle resin is resistant to water, inorganic salts, alkali and acid, insoluble in most alcohols and hydrocarbon solvents, but readily soluble in aldehydes, ketones, esters and certain chlorohydrocarbons.




Disadvantages of ABS engineering plastics: low thermal deformation temperature, flammable, poor weather resistance. Flame retardant plastic transparent socket box add special flame retardant plastic.




Special flame retardants with good flame retardants in ABS mainly include phosphorus, halogen-based organic compounds and some inorganic compounds, among which the proportion of inorganic flame retardants in ABS should reach more than 40% to play an obvious effect. At the same time, because of its large amount of addition, will seriously damage the physical and mechanical properties of ABS. However, phosphorous flame retardants are not suitable for ABS granulation because they are mostly liquid compounds with low melting point. Therefore, the current ABS flame retardant system mainly uses halogen flame retardants, among which the best flame retardant effect is bromo-containing organic compounds, such as decabromodiphenyl ether (DBDPO), tetrabromodiphenol A, etc..
