Product Details

12cavities Pin Valve Hot Runner Pet Preform Mould

BRIEF INTRODUCTION:

1. Tube blank is designed with the help of computer, which surely contributes to the increasing of yield of bottle

2. Using international advanced two stage double taper locating technology. Each cavity self-locks independently to ensure low decent ration of product.

3. Core and cavity are made of special mould steel after preheating treatment in the original factory in Sweden. Individual temperature control for all cavities.

4. Lip cavity is made of imported nitrated steel, which is of high hardness and long service life, in accordance with international Standard.

5. The excellent hot runner design assures uniform heating and greatly improves the quality of plastic product.

6. No cutting of gate is employed to reduce the labor intensity. Standard

Inter-changeable mould components.

7. The life of mould is more than 2 million times.

l Brief Introduction:

² Keep 500 °C about 36 hours in vacuum station to eliminate the stress, make sure the molding board steady after long time use.

² Slipper block use HUSKY type, with material of steel P20, which is highly anticorrsion, all the move parts used advanced ion nitrating treatment, the surface hardness is HRC48-52.

l Spare Parts(Screw, coin and cavity):

² All used material steel 2316, with high anticorrosion and hardness is HRC46-48.

l Hot Runner:

Use SKH61 temperature resistance material, with hardness HRC≥46

² The hot nozzle use italy ROTFIL or German HOTSET heating coil to make sure the quality.

² Plastic injection opening use high hardness QBE2 Beryllium copper, with good conduct heat, anti wear and steady.

² Plastic injection opening heat insulation cap use American Dupont.

² Piston and cylinder use import wear ring, the piston use material 2316, the sealing element used import sealing element, with material of poly four vinyl chloride.

HOT RUNNER SYSTEM

The hot runner adopts the PID controlling system. It has the function of the self repair and self protection, which can prolong life of the heating element. The temperature difference under controlling within 1°C difference. It will make sure that raw material can not be burnt insider of the hot runner. The wastage will be kept less than 1% the new sprayer design make the mould are easy for maintaining, the ejected part of the sprayer, the heating part, the heat insulation, thermocouple part can be changed without disassembling the mould which can save a lot of the time and save the maintaining cost.
