PVC ဆေးထိုးပုံသွင်းစက်တွင် အမြန်နှုန်းကိုချိန်ညှိရန်အတွက် ဆက်တင်များစွာရှိသည်။

ဟိ PVC ဆေးထိုးစက် has several settings for adjusting the speed. ဟိ speed can be varied based on the dimensions of the mold and the thickness of the PVC. High speed can be suitable for thin parts, but a low speed will be sufficient for most parts. ဟိ screw speed should also be set to medium or slow to avoid excess backpressure.

Various types of PVC injection molding machines are available, each with its own set of advantages and disadvantages. Some are mechanical, while others use hydraulic or magnetic clamps. Electric machines, on the other hand, are quieter, faster, and more accurate than mechanical ones. ဟိy also reduce operating costs.

A PVC injection molding machine should be able to meet the exact specifications of the parts it's designed to produce. ဟိ molding system should also have a system to handle the temperature of the PVC material. A temperature of less than 140oC is ideal, and a mold designed to maintain this temperature will avoid any heat-related problems. Moreover, it should have vents to prevent localized brining and short shots.

ဟိ maximum number of injection screws should be around 4mm, and the diameter of the injection nozzle should be around 6mm. ဟိ injection time should be three minutes or less. ဟိ temperature should be adjusted according to the actual conditions. Generally, the injection volume should be 20 to 85% of theoretical volume. Lesser volume will lead to longer residence time and higher chances of degradation after heating.
