GMB#2126 MANUFACTURE OF PREFORM INJECTION MOLDS in INDIA

With a revolutionary reduction in mold pitch to significantly increase productivity using existing machinery and infrastructure.



Developed a new PET hot runner system allowing for an ultra compact mold pitch of 40 mm. Many components remain unchanged from previous generation, allowing common hot runner component inventory.



On the cold half, developed a robust mold stack design for 28 & 30 mm necks where the mold pitch can be set at 45 mm x 100 mm. For neck diameters of 25 mm or less, it is possible to reduce the mold pitch down to just 40 mm x 95 mm.



Some benefits of a lower pitch are as follows-

Allows for higher cavitation and hence production rates on the same machine size.

Reduces energy consumption in the hot runner as surface for heat loss per cavity is reduced. This also reduces the load on the chiller for cooling of the backing plates.

Reduces material degradation in the hot runner with shorter flow path (lower shearing and residence time).

Reduces per cavity stress on the clamping unit and energy consumed for mould open & close.

Increases overall clamping surface to absorb clamping force, thus increasing mould life.



Based on this new technology, built a 96 cavity mold with a pitch of 45 mm x 100 mm for the Husky GL/LX/XL 300 machine.



As of date, the highest cavitation generally being run on these 300 ton machines is predominantly 48 drops and in a few cases 72 drops. With our new technology, convertors can increase their production rates to up to two times, shot size and plasticising capability permitting.
