Bottle Mould

bottle mould
The requirement of PET bottle has accordingly become more and more, which leads many investors to set foot on the PET bottle production field. To meet the different requirements for the PET bottle, bottle mould from different customers, Yichuan has successfully developed advanced hot runner bottle mould from 1 cavity to 72 cavities for standard neck PET. Its wide utilization and reliable property with the economic investment, the shortest production startup time and the lowest maintenance cost make bottle mould be most popular among bottle manufacturers. Now we do have 2 series bottle tool designs, one of series adopts rectifying system for bottle’s wall thickness, and another series is standard structure.  
Bottle Mould Features
1. Mould ranges from 1 cavity up to 72 cavities
2. Advanced structure is designed consulting European bottle mould.
3. Mould cavity and Core are made of steel with fine polishing, high hardness and anti-corrosion to get mold's high precision and good quality.
4. Pneumatic drive the nozzle pin for simultaneous high-speed open and close actions.
5. Patent designed rectifying system is adopted to lessen the possible bottle thickness problem happening during production.
6. Special designed water hoses eliminate leakage and water marks on bottle.
7. Mouldflow analysis reduce AA level.
8. Long using life over 2.5 million times of injection cycle.
Bottle Mould design
Yichuan Machinery designs not only bottle with standard neck size for water bottle, carbonated drink bottle and oil bottle, also design bottle of special shape responding to customer’s request. Yichuan adopts a wide range of computer-aided engineering service from design conception to the finished products to make customer satisfied.
Valve-gate system
Yichuan series bottle injection mould adopts an advanced valve-gate unit, which is used to control the mold’s injection hole open & close on each cavity. Reliable sealing function, smoothing moving, low thermal expansion rate, and long using life are its main features.
Patent designed rectifying system for bottle’s wall thickness
The patent designed rectifying device is equipped to rectify the bottle thickness during bottle production. The bottle thickness can be adjusted below 0.05mm.
Heating system
Yichuan series bottle mould with double heating system ensures perfect heating effect. It has separate temperature control mode: the heater bars are used to heat the mould’s manifold plate; the small heaters are used to supply the continuous heating temperature for cavity nozzle.
Cooling system
A specially designed cooling system with perfect cooling effect for each inner parts including core, cavity and valve gate system of Yichuan bottle injection mould.
Hot runner system
Yichuan series bottle injection mould adopts specially designed hot runner system to achieve ideal and prompt heating effect for bottle production. Lager flowing channels of such hot runner system ensures the mold to produce bottle with lower injection pressure, which reduces mold’s each part’s wear & tear and maintenance cost, and also saves electric energy.
Steel material and machining tools
Mould cavity and Core are made of imported mould steel with fine polishing, high hardness and anti-corrosion to guarantee mould's high precession and good quality.
Digital Control Lathe, EDM, jig-boring machine and high-precision grinding machine have been used on mould machining. High machining precision and fast machining speed ensure Yichuan’s high quality moulds.
Heat treatment
After mechanical treatment, enhance steel’s strength and prolong mould service life. For example, we coat chrome on the mould plate surface for rustproof purpose and go on nitrogen treatment on neck part to increase its hardness. Special coatings also are available at Yichuan Machinery. With right operation, bottle mould reaches 2.5 million shots.
After-purchase service
Each set of bottle mould undergoes strict mould trials before shipping from factory and attaches full set of parameter that is recorded depending on their own and sole serial number. Together with the bottle mould, full set of spare parts will be supplied for free to keep mold normal working. In the use of the bottle mould, Yichuan provides adequate spare part to any request and Yichuan service department are very willing to provide technical support immediately for any possible request in any time.
