PET preform Mould with 48 cavity hot runner valve gate PCO28mm neck preform PET preform injection mold

PET Preform Mold Features

1. There are 4 cavities up to 72 cavities on PET preform mold.
2. Electric control system with simulating stretch testing improve yield rate.
3. Adopt world advanced dipole taper localization technique, each cavity self-clamp independently, ensure mold concentricity.
4. The material of mold die core and die cavity are made of Sweden special mold steel.
5. International standard screw neck, imported nitrided steel with high hardness is of long usage.
6. Advanced hot runner design and even heating temperature make sure the high quality of plastic products.
7. Valve gated type without tail reduces labor force.
8. At least 3 million guarantee.PET Preform Mold DesignWe designs not only preform with standard neck size for water preform, carbonated drink preform and oil preform, also design preform of special shape responding to customer’s request. We adopts a wide range of computer-aided engineering service from design conception to the finished products to make customer satisfied.Valve-gate system

Our preform injection mold 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 preform’s wall thicknessThe patent designed rectifying device is equipped to rectify the preform thickness during preform production. The preform thickness can be adjusted below 0.05mm.Heating system

PET preform mold with double heating system ensures perfect heating effect. It has separate temperature control mode: the heater bars are used to heat the mold’s manifold plate; the small heaters are used to supply the continuous heating temperature for cavity nozzle.

Cooling systemA specially designed cooling system with perfect cooling effect for each inner parts including core, cavity and valve gate system of Yichuan preform injection mold.Hot runner system

preform injection mold adopts specially designed hot runner system to achieve ideal and prompt heating effect for preform production. Lager flowing channels of such hot runner system ensures the mold to produce preform 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 toolsMold cavity and Core are made of imported mold steel with fine polishing, high hardness and anti-corrosion to guarantee mold's high precession and good quality.
Digital Control Lathe, EDM, jig-boring machine and high-precision grinding machine have been used on mold machining. High machining precision and fast machining speed ensure Yichuan’s high quality molds.Heat treatmentAfter mechanical treatment, enhance steel’s strength and prolong mold service life. For example, we coat chrome on the mold plate surface for rustproof purpose and go on nitrogen treatment on neck part to increase its hardness. Special coatings also are available at our Machinery. With right operation, PET preform mold reaches 2.5 million shots.After-Sales ServiceEach set of PET preform mold undergoes strict mold 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 PET preform mold, full set of spare parts will be supplied for free to keep mold normal working. In the use of the PET preform mold, 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.

PET Preform Mould Main Components Specification and Advantages
Main component	Specification and Advantages
Core	2316 steel from Sweden	high-quality special mould steel from sweden (HRC >45) gurantee 2 million shots without any maintenance
Neck	S136 steel from Sweden, HRC >60, International standard screw neck
Cavity	2316 steel from Sweden Each cavity have an independent temperature controller Each cavity self-clamp independently, ensure mould concentricity. 0.05-0.06mm
Body	P20 Steel material from Germany
Hot runner plate	2344 Steel material from Germany
Slider Plate	wear-resistant copper
specially designed cooling circuits	Proper design reduce molding cycle time to 15 seconds( with proper water chiller and injection machine) about 3-5 shots per minute
Hot runner design	make sure the high quality of preform products.
Heater	Anole Germany
valve gated design with Automatic drop	each cavity has its independent heating zone and temperature is measured by independent thermocouple. .(advantages: easily avoid some problems such as white or draw bench on bottom). Valve gated type without tail reduces labor force.
Precessed by high presion CNC machine and numerical control loathe machine	Lowest weight and dimensional variation thickness between max. part and min. part is not more than 0.05mm make sure that every parts can match well
