PREFORM MOULD PARTS
Your preform mold matching expert!
Mold stacks material
-Imported Stainless steel from ASSAB Sweden for mold stacks and other essential components;
-Hardness up to HRC49-HRC51 after special heat-treatment
-Stable performance
-Long life span to create value for customer
-Taper matching design for core and lockring, good for venting and easy for neck solidification;
-Double taper design neckrings, which allow high injection force without flash;
-Cavity water flow adopts spiral type independent of cycle structure which is good for fast cooling of preform;
-High precision grinding machine for taper machining;
Huiyuan mold hot runner characteristics
-Manifold applied rational balance design,we did material flow simulation for each mold ;
-Inner channel diameter size is different according to different flow rate requirements;
-Equal temperature of each section;
-Heaters routed along melt channels& Geometrically balanced melt channels including level changes;
-Cylinder mounted on the mainifold platen, higher match up precision ensures no deformation of the valve stem, meanwhile less dust and resin leakage;
-Piston uses high temperature resistance sealing components, maintenance time extends to 2 years;
