– Stainless steel or P20 for mould base plate, all plates will be nickel plated, the HRC is 38-40.
– ASSAB STAVAX ESR S-136 (SWEDEN) or 2316(Germany) for core, cavity and neck ring, the HRC is 48-52.
– Graphite copper plate under slide plate, with better lubrication effect.
– The valve pin imported from JAPAN, with material SKD61, HRC is 48-51.
– The insulator is DuPont from USA.
– The nozzle made by Beryllium bronze with HRC 38.
– The mini coil heater from Italy ROTFIL or Germany HOTSET.
– PID temperature controller.
1. The weight tolerance is +/- 0.2gram (depend on the total weight of the perform).
2. The thickness tolerance is +/- 0.1mm (depend on the length of the perform).
3. Efficient cooling system on core, cavity, neck insert and plates, better for shorten cycle time.
4. The guarantee of the mould is 3,000,000 shots.
5. There will be the serial number on each neck and plate of perform mould.
THE ADVANTANGE OF PET VALVE TYPE PREFORM MOULD
· Cavity, core, screw neck of steel adopt ASSAB STAVAX ESR S-136 (SWEDEN) or 2316(Germany), and be heating treatment of Hardness up to HRC 48-52.
· Advanced mould design technology.
· Each Cavity self-locks independently and using high precision CNC SYSTEM.
· Each mould spare part IS inserted with durable parts, which are interchangeable.
· To ensure low eccentricity & precision of the product.
· Pin valve hot runner system improved on HUSKY technology,to ensure the high transparency & brightness of product.
