What performance characteristics does it have?
ABS plastic (acrylonitrile-butadiene-styrene) English name: Acrylonitrile Butadiene Styrene Specific gravity: 1.05 g/cubic centimeter Molding shrinkage: 0.4-0.7% Molding temperature: 200-240℃ Drying conditions: 80-90℃ 2 hours
Material properties: 1. Good comprehensive performance, high impact strength, chemical stability, and good electrical properties. 2. Good weldability with 372 organic glass, and can be made into two-color plastic parts, and can be surface chrome plated and spray painted. 3. Available
High impact resistance, high heat resistance, flame retardant, reinforced, transparent and other grades.
4. The fluidity is slightly worse than HIPS, better than PMMA, PC, etc., and has good flexibility.
Suitable for making general mechanical parts, wear-reducing and wear-resistant parts, transmission parts and telecommunications parts. Molding properties 1. Amorphous material, medium fluidity, high moisture absorption, must be fully dried, plastic parts requiring glossy surface must be preheated and dried for a long time
80-90 degrees, 3 hours. 2. It is advisable to use high material temperature and high mold temperature, but if the material temperature is too high, it will easily decompose (decomposition temperature is >270 degrees). For plastic parts with higher precision, the mold temperature should be 50-50
60 degrees. For high-gloss and heat-resistant plastic parts, the mold temperature should be 60-80 degrees. 3. If you need to solve the problem of water lines, you need to improve the fluidity of the material, adopt high material temperature, high mold temperature, or change the water level.
and other methods.
4. If heat-resistant or flame-retardant materials are formed, plastic decomposition will remain on the mold surface after 3-7 days of production, causing the mold surface to shine. The mold needs to be cleaned in time, and an exhaust position needs to be added to the mold surface.
