The two-head thread can be extruded mainly, and the heating is uniform and short, self-cleaning performance. Good (common) • d, three-thread thread, flexible choice of material pressure and temperature distribution at the machine angle, stable fiber, good surface renewal effect, but low output. • “M...

I. Extruder classification Product code Specification parameter description: For example, SHJM-Z40×25×800, the screw diameter is 40mm, the aspect ratio is 25, and the length of the traction roller is 800mm. The twin-screw hybrid plastic extrusion modified film machine. 1, "SH" category code, refers ... Read More
The main factors affecting the quality of plasticization are: aspect ratio, compression ratio, back pressure, Screw speed, barrel heating temperature, etc. 1. Length to diameter ratio: the ratio of the effective working length of the screw to the diameter of the screw. a, the ratio of long diamete... Read More
1, screw diameter (D) a, related to the required injection volume: Injection volume = 1/4 * π * D2 * S (injection stroke) * 0.85; b, in general, the screw diameter D is inversely proportional to the highest injection pressure, and is proportional to the plasticizing ability. 2. Conveying section a, ... Read More
Generally, the screw is divided into three sections, namely, a feeding section, a compression section, and a homogenization section. Feeding section - the bottom is small, the main function is to transport the raw material to the rear section, so it is mainly the conveying capacity problem, the pa... Read More
