MICROPROCESSOR CONTROL IN INJECTION MOLDING
MICRO PROCESSOR CONTROL: OPEN LOOP AND CLOSE LOOP
Why Micro processor required?
To ensure consistency of quality of injection moulded parts one has to look at the controls like pressure, speed, stroke & temperature. This is...
VARIOUS CLAMPING SYSTEM IN INJECTION MOULDING
CLAMPING SYSTEM: MANUAL, TOGGLE, HYDRAULIC, HYDRO-MECHANICAL & T BAR LESS CLAMPING
The function of clamping unite is to clamp the injection mould. The clamping pressure is set more there the injection pressure, so that the...
MATERIAL SELECTION FOR THE INJECTION MOLDING
MATERIAL SELECTION FOR THE INJECTION MOLDING
Material selection depends to a large extent on the functional constraints of the part. Both amorphous and crystalline thermoplastic resins are used in injection molding. Short glass fibers are...
