Usually, Multi-cavity pet preform mould does use the hot runner system rather than cold runner system, so the design of hot runner system plays an important role in mould quality guarantee. Based on foreign advanced techniques and combined with domestic clients' demand, we adopt the valve gated design, in which each cavity has its own heating zone and temperature is measured by independent thermocouple. (advantages: Easily avoid some problems such as white or drawbench on bottom). Here, Mould is produced automatically to reduce labor force.
The main components of moulds ( die core, die cavity and screw neck) are made by injection process, which are made of special mold steel ( Germany steel 2316) after preheating treatment in the original factory in Germany. In this way, the mould with long life service and high quality can be used for 2 million shots without any maintenance, meanwhile, the wall thickness between max. Parts and min. Part is not more than 0.10mm. We adopt mould base of 50# steel and sliding block of 718# steel. And the moulds equipped with imported components including high-qualitied lubricating copper plate, Germany heaters HOTSET, Germany standard PID temperature controller. Moreover, turning center processes make sure that every parts can match well; Proper distribution of cooling water way improve productivity effect and molding cycle only takes 15 seconds( need proper water chiller, bottle design and injection machine)
Our mould, designed and developed by our engineers, is of high precision and long life span without traditional problems. In a word, Preform wall thickness is on error of 0.10mm; Weight difference is less than 0.3g; 2-5 moulds per minute; 2 million guarantee; Utmost 96 cavities in one mould.
72 Cavities,Plastic PET Preform Mold & Injection Mould
Main feature:
1. Mold cavity from 1 up to 96.

5. International standard screw neck, imported nitrided steel with high hardness is of long usage.
6. Advanced hot runner design and even heating temperature make sure the high quality of plastic products.
7. Valve gated type without tail reduces labor force.
8. At least 2 million guarantee.Â
A sealant is a substance used to stop fluids from passing through a seam or opening in a surface or material and is a type of mechanical seal. In building construction, sealants are sometimes synonymous with caulking and are also used to block the transfer of dust, sound and heat. Sealants can be weak or strong, flexible or rigid or temporary. Sealants are not adhesives, but some have adhesive properties and are called adhesive sealants or structural sealants.
Although not very strong, sealants have many properties. They seal the top structure to the substrate and are particularly effective during waterproofing by keeping moisture out of (or in) the components that use them. They provide thermal and acoustic insulation and can be used as a fire barrier. They may also have electrical properties. Sealant can also be used for simple smoothing or filling. They are usually required to perform several of these functions at a time.
A caulk sealant has three basic functions: it fills the gaps between two or more substrates; it forms a barrier through the physical properties of the sealant itself and its adhesion to the substrates. And it maintains hermetic properties over the life expectancy, usage conditions and environment. Sealants perform these functions through the correct formulation to achieve specific application and performance characteristics. However, aside from adhesives, there are few other functions that can replace the sealing process.
