Product Description                                                                                                                                      

QL = π / 4 D2 S does not reach oretical value during working , because density of changes with change of and ,custom plastic components refore, capacity needs to be properly corrected, and modified capacity is Q=αQL=π/4 D2 Sα, α—— coefficient is generally 0.7∽0.9. s are ed on . quality of general and total amount of casting system do not exceed volume of . 25% ∽ 70% is good, (2), - force of screw or plunger end face acting on unit area of  melt, size of and structure of , flow resistance, shape, properties izing method, izing , structure, and accuracy requirements of s, etc. In actual , can be adjusted within allowable range of . should be selected according to actual situation. selection range is as follows. A has good fluidity, simple shape and large arm thickness. Generally, is less than 340∽540Kgf/cm2. Suitable for ing LDPE, PA and or s. B has low melt viscosity, and precision is general. custom plastic components is 680∽980Kgf/cm2. Suitable for ing s such as PS and HDPE. C melt viscosity is medium or , accuracy is required, shape is complex, is 980∽1370Kgf/cm2. Suitable for ing of PP, PC and or s. D has melt viscosity, custom plastic components is thin wall, long , precision and complex shape, and is 1370∽1670Kgf/cm2. Suitable for ing nylon, polysulfone, polyphenylene er and or s. E When ing -quality precision micro-s, can reach 2260∽2450Kgf/cm2 or more. In order to meet ing requirements of precision s or complex structural shapes and engineering structural parts, has enhanced ing adaptability, shortened cycle custom plastic components, improved quality, and increased . (3) ( speed,) - melt begins to cool after passing through nozzle. In order to inject melt into cavity in to obtain a dense and uniform with precision, melt must be filled in a short . In addition to having sufficient , cavity must have a certain flow rate to indicate parameters of melt filling speed. (4) izing ability—— amount of that can be ized in a unit ,custom plastic components izing capacity of general screw is related to screw speed, driving power, screw structure, performance and so on. izing device of should be able to provide a sufficient amount of ized uniform melt within specified . izing capacity should be coordinated with entire cycle of . oretical izing capacity of general is greater than actual one custom plastic components. About 20% of demand. 2 Basic parameters of clamping system (1) Clamping force - maximum clamping force applied by clamping mechanism to . Under this force, should not be topped. It reflects size of that can be ed by to a certain extent. It is an important parameter. Our company adopts maximum clamping force as specification of . Before melt is injected into cavity at a certain speed and , it is necessary to overcome resistance flowing through nozzle, runner, gate, etc., and some of will be lost, but melt also has a relatively when filling .
