Preform molds gate system:
PET Preform Mould sprue gate can be divided into long gate, short gate, and needle valve gate. When it comes to gate, we will think of the valve gate hot runner, the advantage of valve gate is as follow:
1. Surface sprueless traces for fine surface processing
2. Built-in valve needle, valve needle is control by pneumatic or hydraulic
3. Timing control, the switch can be controlled
4. Sealing performance, smooth surface and high speed.
Preform moulds thickness design:
PET preform like 28PCO, 3025, 1881 standard its PET preform wall thickness should not be over 4mm, and the distance between PET preform neck and the bottle body should leave out at least 3-5mm.
The wall thickness of this distance could not be too thick, usually is 2mm. If the PET preform wall thickness too thick, it will be very difficult to blow the bottle.
Preform molds cooling system:
Both the preform molds core and preform moulds cavity side has cooling channel. But the cooling channel is different, preform molds core cooling system is like fountain design, this design could make the preform molds cooling better. The preform moulds cavity cooling system is helical which could cool down whole preform moulds cavity very fast.
Next, let us talk about the injection molding machine, choose for different cavities preform moulds. Taking 28mm neck size preform molds as an example, let us talk about the machine we need for above different cavities preform molds.
24 cavities preform molds: 268T injection molding machine
32 cavities preform moulds: 330T injection molding machine
48 cavities preform molds: 500T injection molding machine
72 cavities preform moulds: 650T injection molding machine
The machine clamping force must be very enough, otherwise will have problem in preform moulds molding.
