ABS AF-312 properties

ABS AF-312 properties: 
better overall performance, high impact strength, chemical stability, good electrical properties. 
plexiglass with 372 good weld made ​​of color plastic and chrome plated, paint treatment . 
High impact, high heat resistance, flame retardant, enhanced transparency level. 
Mobile than HIPS almost, than PMMA, PC, good, good flexibility. 
Suitable for production of general machinery parts, less wear resistant parts, transmission parts and telecommunications parts. 
molding properties: 
amorphous material, liquid medium, large moisture must be fully dried, the surface gloss plastic parts required to be long preheating dry 80 -90 degrees, three hours. 
should take the high melt temperature, higher mold temperature, melt temperature is too high decomposition (decomposition temperature> 270 degrees). pair of high precision plastic parts, mold temperature should be 50-60 degrees, high gloss. resistant plastic parts, mold temperature should take 60-80 degrees. 
To resolve clip waterlines need to improve the mobility of the material, take the high melt temperature, high mold temperature, or change into water and other methods. 
Such as forming heat-or flame retardant materials, production 3-7 days after the remnants of plastic mold surface decomposition, leading to the mold surface shiny, the need for timely clean up the mold, the mold surface at the same time the need to increase the exhaust position. 
Cooling speed, die casting system should be thick, short of the principle should be established cold-slug, the gate should be large, such as: direct gate, disc gate or fan gate, etc., but should prevent the stress increases , if necessary, can be used to adjust gates. Mold should be heated, wear-resistant steel should be used. 
Material temperature greater impact on the quality of plastic parts, material temperature is too low will result in lack of material, matte, silver disorders melt temperature is too easy to overflow edge strip, silver and dark, discolored plastic parts blistering. 
Mold temperature greatly affect the quality on plastic parts, mold temperature and low shrinkage, elongation, impact strength, flexural, compressive strength, tensile strength is low. Mold temperature over 120 degrees, the plastic cooling slowly, easily deformed stick mold, mold problems, long molding cycle.
