Hot-half Mold Features
Balanced manifold design enable our mould to achieve very small tolerance in each individual preforms.

Multi-layer hot runner with three point filling structure ensures balanced injection of each cavity.
Square heater pipes are laid around the manifold to deliver heat equally around each injection points.

Nozzle tip heating is individually controlled by voltage and heating zones are adjustable, which minimizes the possibility of AA generation.

Main parts used in our hot runner such as nozzle tips, insulators, heaters are imported from Europe and USA and they are interchangeable with world branded moulds.

Cold-half:
Mould plates are made of 420 heat treated stainless steel, interal stress of which is eliminated by hardening and tempering; S136 high strength anti-

Corrosive stainless steel with hardness greater than 48HRC is used for mould stacks.

Compact designed mould with high precision machining ensures molded preform free of defects like flash, bubbles, incompatible dimensions etc; Preform wall Thickness variation is able to achieve less than 0.12mm.

Cams and cam followers with bearings made from high strength anti-corrosive S136 stainless steel are adopted for preform demoulding. All contacting

Surfaces are filled in with lubrication copper alloy to reduce wearing.

Mould structure including mould plates, stacks etc. Its easy essembly & dismantle features is compatible with international branded moulds.

Spiral type water circuits leads to fast preform cooling.

Surface heat treatment is conducted for all contacting surfaces to make sure smooth and durable running of the mould.

Axial matching design in between neck ring and cavity guarantees the same axial rate in preform.
