Types of Pet Moulds

If you're interested in sourcing PET preforms,

I it's imperative to work with a reputable manufacturer. While recycled PET materials are available, they cannot be added to your preforms in large enough quantities. You should also consider mould temperature and cooling speed, as low temperatures or fast cooling rates can cause an opaque PET preform. This is especially important in the bend section of the mould. 

A good PET preform mould will combine high functional strength with strong sales appeal, while also offering competitive pricing. The material and processes you use to construct the mould are essential to its success. A mould must be durable and use specialized steel. Specially designed water channels will minimize the chance of jamming. A properly designed mould will also be easy to maintain, and will hold up to 2.5 million injections.

mould factory offers high-precision, high-grade steel for the production of high-quality PET preforms. Its high quality, superior polish and anti-rust properties make it a good choice for PET preform moulds. The nozzle pin and slide insert are made of steel and are connected to hydraulic cylinders of European or Japanese origin. The nozzle pin is specially designed to synchronize with the movement of the PET preform mould plates.

A pin-valve type of hot runner system is a powerful tool that is capable of cutting processing times, part wear, and electricity consumption. The hot-runner plate's capacity is increased with the help of a heating band imported from Germany. Its dual-heating and cooling system ensures high quality control and consistent results. The heat coils maintain the nozzles' temperature throughout the entire cycle.

Valve-gate hot runner systems are characterized by valve gate technology. The valve gate is automatically closed when injection takes place, leaving no visible nubs or abrasions on the final product. These systems are ideal for a highly aesthetic moulding project, but they cost more. Valve-gate systems are best for moulding materials that require high cavitation and a smooth surface.

Hydrophilic

A Hydrophilic pet mould factory uses a hydrophilic resin as the core material in the injection molding process. Its properties depend on the conditions under which it flows and solidifies. The molten polymer first solidifies along the mold's walls, but it also solidifies in the central region when there is no shear elongation. This results in a skin of highly-oriented polymer surrounding a core of less-oriented material. The two layers are mechanically and optically distinct.
