Injection volume varies to the resin used, thickness of the product, injection speed and gate diameter.The following figures are the reference for helping to understand the various type of gate system.Please contact YUDO representative or agency for an actual application.

BALA nozzle has 4 standardized sizes and each size has various gate diameters.The size of nozzle is displayed after the type name(e.x. BIM 25 : BALA nozzle 25), and determines the injection volume of nozzle.

- "L"can be adjusted by order

Actual length of nozzle when delivered

Actual length of nozzle (BL) = L - L - T L : (L - 30 - T) 1.2 e-5 (Injection temp. - Mold temp.)

(BL) = L - L - T L : (L - 30 - T) 1.2 e-5 ( )

Single Nozzle has 4 standardized sizes and each size has various gate diameters.Nozzle size is labelled after the Type Name. (ex. BIS 25 : BALA Single Nozzle 25), and determines the injection volume of the nozzle.Only for general purpose material under 230 operation temp. And if operation temp. is over, BLS nozzles should be applied.
