GSH- pressure flow closed loop series injection moulding machine

A stable injection molding machine performance, high repeat accuracy:

　　"Light plastic" H-type injection molding machines, hydraulic closed-loop control system based on the principles of high-response control, HPQ high response electro-hydraulic valve to the closed-loop feedback control system, to add to the pressure and flow control valve position sensors, repeat after correction feedback via a controller operation pressure and flow valve, the highest frequency sound reaches 23ms / 13ms, and therefore achieve consistency each injection quantity.

　　2, product qualification rate, reducing the failure:

　　Because the amount of after each injection to improve stability, the test mode setting after the injection amount of each of the control and stability, and therefore able to improve the pass rate, especially in multi-cavity (Example 1 10) less than an occasional chipping or injection molding capacity adverse finished product, if used HPQ high response valve start back from the first mold injection quantity is essentially the same, security guarantees precision injection molding, injection of the most obvious benefits.

　　3, overcome to meet high precision, high difficulty of injection molding injection molding products:

　　For high-precision size or liquidity faster / slower product of molding conditions, with the valve in response HPQ high response speed is very precise: to ensure the injection pressure and flow rate does not change, or changes in response to the cavity, the rapidly changing needs of pressure and flow injection molding process, HPQ high response valve is fully able to meet, such as IC cards, lenses, mobile phone, camera case, and so a combination of size requirements, higher transparency products, particularly adapted.
