Preform mould features:
Neck rings designed in two parts to ensure the same axial degree of preforms in molding;
Optimized water-cooling channels to enhance preform cooling in mold and to guarantee fast cycle time;
Mold stacks are made of S136 stainless mould steel; the steel will be heat treated before finish tooling;
Plates and other parts of the frame are made of 4Cr13 stainless mold steel.
Hot-runner channels have the top engineering in balance design;
Valve gate advanced structure.
Main parts of hot-half mold such as heaters, valve-stems are imported from Europe.
Drops are controlled individually and heating zone temperatures are adjustable, AA value from thermal degradation is minimized.
Mold test:
The finished mold will be tested in our factory before delivery.
Preform acceptance:
Preforms molded from our factory are in optical clarity international standards.
Preform wall thickness variation within 0.12mm can be achieved for preform with standard neck.
Preform will be accepted in accordance with preform drawing.
