The design also provides greater flexibility in molding applications by compensating for variations in preform ejection velocities from machine to machine and providing positive controlled-cam actuation for preform sizes.Ĭopper spiral cooling tubes provide concentric alignment with core cooling channels for uniform preform cooling and raise the turbulent flow rate to increase the heat transfer coefficient, resulting in greater cooling efficiency and minimized cycle times. This feature protects against mold damage in the event of slide closure on the preforms by absorbing the transmitted energy through the closing cams.
Thread split assembles are actuated by our patented energy absorbing cam track system. This feature prevents direct heat transfer from the hot manifold to the cylinder walls, premature seal and cylinder wear, and piston seizure due to resin discharge. Pneumatic valve-gate cylinders are retained in water cooled mold plate, completely isolated from the extreme heat of the hot manifold and the valve-gate cylinder resin residue can be discharged in a non-critical area. Profiles cooling channels facilitate efficient heat transfer from the preform spherical radius and gate area to minimize crystallinity. One-piece cavities eliminate parting line coolant leaks, eliminate nozzle gate inserts, and allow for water cooling channels to be profiles to the shape of the preform. This alignment ensures concentric material distribution from the nozzle into the injection cavity resulting in less leverage on the cores during injection therefore, more accurate control of preform wall thickness variation.

Preform mold cavities, nozzle housings and nozzles are also located by the same jig-ground bore diameters in the mold bases. Name Description Preform tube mold core and cavity s136 steel (48-50HRC) Mold base 45, 50, P20 ( with pre-hardening process) Mold base brand LKM, HASCO, DEM, etc. To achieve concentricity between core and cavity mold halves, final mold base bore diameters are jig-ground. Jig-Ground Critical Alignment Diameters:.
Molding surface components are made of ASSAB steel, hardened and ground to 45 Rockwell “C” in addition, all cooling channels are electro-less nickel plated to prevent corrosion. the mold heating temperature is too high reduce the heating temperature of the warmer, generally set: 280 285 ° C. Answer (1 of 5): Im going to guess that the correct term you are asking about is a ‘PET preform mould’ not ‘preformed’, just to help clarify things. Master Packing Co.,Ltd was founded in 1997, is a professional China PET preform molds manufacturers and PET preform moulds factory.Because of Advanced CNC machinery, 5 axis drilling machine, Lathe, a group of more than 15 years experienced engineers, Master brand Packing machine now exported more than 87 countries and district. We use only the best mold steel available. This simple feature can prevent hundreds of downtime hours per year. Molding surface components, Valve-gate assemblies and hot manifold components can be removed, serviced and re-installed without removing the mold from the machine.
