Changshu smoothly da plastic products factory talk about ABS profiles extrusion die design principle of the big four

ABS extruding is common in construction and other industries a kind of engineering plastics, the main advantage is that under the condition of high temperature deformation, also won't condensation, this is mainly due to the ABS thermal deformation temperature can reach 95 degrees. Not only that we in the production process by adding antioxidant and light stability of the reagent, effectively reduced because absorb uv light to make it look yellow. These advantages that ABS extruding popular! ABS extruding application field is very broad, and its products mainly processing method for injection molding, extrusion and thermoforming. So how ABS extruding is produced? Today, ABS extruding production without mould, changshu smoothly da plastic products factory talk about ABS in extrusion die extrusion die design should follow the four principles!



1, each template compact connection, reliable, convenient disassembly, use safety.



2, adopts streamlined crossing ever-flowing mould structure, reasonable size of runner system design. Its mouth die clearance = products wall thickness & times; ( 0. 95-1. 0) Magnification, ABS profiles extrusion die mold size = 1. 01 ~ 1. 05, forming length: die clearance = 25 ~ 38, compression ratio = 2. 8 ~ 3. 5, compression Angle = 10 & deg; ~ 15度; 。



3, each template R a&le mould cavity and core surface roughness; 0. 2μ M, and a smooth transition, no dead Angle, steps, to avoid stagnation, rupture occurred when the melt extrusion and decomposition.



4, setting the port at the shunt bar, or used in shunt period & other; Multi-cavity independent feeder system & throughout; To reduce the mutual interference between material flow, the flow is more stable.
