Core pins and sleeves refers to the resin (or in the process of using the monomer polymerization as main component, in order to core pins and sleeves, fillers, lubricants, additives coloring agents as auxiliary components, can flow forming material during processing. Core pins and sleeves has the following characteristics: most core pins and sleeves light weight, good chemical stability, no corrosion; the good impact resistance; the transparent and has better wear-resistant consumption; the good insulation, low thermal conductivity; the general shape, color is good, the processing cost is low, the part of core pins and sleeves refractory poor, thermal expansion, and easy burning, poor dimensional stability, easy deformation; majority of poor - temperature - resistant core pins and sleeves, low temperature brittle, the easy to aging, core pins and sleeves soluble in certain solvents
