Industrial 144 Cavity Hot Runner PET Preform Mould for Water Bottles Features
Engineering Starts from the Bottle
SZ-MOLDTECH does not select a PET preform mould based on cavity count alone. The engineering team first looks at the bottle application, neck finish, preform weight, wall thickness, filling method and injection machine. These details help define the mould structure before the project moves into production.
Integrated Mould Manufacturing
Mould design, precision machining, component processing, assembly and trial runs are coordinated within the SZ-MOLDTECH production system. Keeping the key manufacturing stages under one roof makes project communication more direct and allows production issues to be addressed without unnecessary handovers.
Experience Across PET Preform Applications
A preform mould has to work as part of a complete packaging line. SZ-MOLDTECH considers requirements from preform injection, stretch blow moulding, filling and cap matching when discussing a project. This practical approach helps ensure that the mould is designed around the final bottle rather than treated as an independent component.
Project Control from Design to Trial
Each project moves through defined stages, including technical confirmation, mould design, machining, assembly and testing. SZ-MOLDTECH keeps customers informed when key specifications are confirmed or changes are required, making it easier to follow the actual progress of the mould.
FAQ
What information does SZ-MOLDTECH need to quote a PET preform mould?
SZ-MOLDTECH normally needs the preform drawing or sample, neck finish, preform weight, cavity number, bottle application, injection machine model and expected production capacity. If the bottle design is still under development, the team can also review the available technical information and help confirm the suitable mould structure.
How does SZ-MOLDTECH handle high-cavity PET preform mould projects?
For high-cavity moulds such as 96, 128 or 144 cavities, cavity balance becomes particularly important. SZ-MOLDTECH pays attention to the hot runner layout, cooling distribution, cavity positioning and dimensional consistency so that each cavity can maintain stable production performance rather than focusing only on increasing the cavity number.
How does SZ-MOLDTECH approach cooling design for high-cavity PET preform moulds?
For high-cavity moulds, cooling consistency directly affects cycle time, preform quality and cavity-to-cavity stability. SZ-MOLDTECH considers the cooling channel layout, water flow and temperature balance during mould design, with the aim of maintaining more consistent cooling conditions across the entire cavity arrangement.
How does SZ-MOLDTECH handle mould testing before delivery?
After assembly, the mould goes through trial production to check key operating conditions and preform quality. The team examines factors such as filling consistency, parting performance, cooling balance, hot runner operation and ejection. Any issues identified during the trial stage can then be addressed before the mould is delivered to the customer.
