Molding system plays an important role in food & beverage packaging industry Pudong plastic adopts latest engineering innovation, metalworking technologies, and mold making know-how to design, manufacture and test PET preform molds. Pudong plastic PET preform mold assures the customer to produce high-quality PET preforms at high productivity, but with most economical investment, shortest start-up time and lowest maintenance cost. With Pudong plastic PET preform mold, medium and small size company can produce PET preforms by themselves and also satisfy the fresh brood s production requirement in PET field. We are enjoying a good reputation on manufacturing close tolerance molds manufactured to rigid customer specifications.

Professional PET Preform Design
>> Make Imagination into Reality Based on the years experience and integration with most advanced mold technology on the world, Pudong plastic can design preform with both standard and non-standard neck/shape/volume for water bottle, CSD bottle and oil bottle with perfect bottle blowing performance as per customers bottle requirement.
Long Service Life
>> Over 2.5 Million Shots
Pudong plastic PET Preform Injection Mold enjoys a service life over 2.5 million shots, based on scores years design/manufacture experience, mold making know-how, adoption of CNC machining center, high-precision EDM shaping machine and high precision Jig Boring machine.
Steel Material and Machining Tools -- Precision
High quality steel like special Anti-rust Mold Steel and Alloy Steel is used to build molds different parts. High original hardness and nice machining performance is above steels mutual features.
Heat Treatment for Mold Building -- Strong
Pudong plastic does twin heating treatment for molds inner parts to enhance their strength and prolong their using life. After Treatment, the mold cores surface hardness can reach HRC 58~60 degree. After heat treatment, hard chrome plating will be adopted on Pudong plastic Preform Injection Molds inner part. On normal condition, Pudong plastic Preform Injection Mold can go on 2.5 millions times of injecting production cycle at least.

Gate-Free Preform
>> Labor-Saving Valve-Gate Sealing System -- Gate-free Preform
Pudong plastic Preform Injection Mold adopts Pneumatic Valve-Gate Sealing System to produce gate-free PET preform, which can save much labor and material cost, also reduce the molds wear & tear extent for customer.
Hot Runner System
Pudong plastic Preform Injection Mold adopts specially designed Pin-Valve type Hot Runner System to achieve ideal and prompt heating effect for preform production. Moreover, such hot runner system reduces molds each parts wear & tear and maintenance cost, and also saves 10~15%s electricity.
Heating System -- Quick Response but Energy-saving
Pudong plastic Preform Injection Mold adopts double Heating system to ensure perfect heating effect and reliable quality control. The Heater Unit is used to heat the hot runner plate with long service life and powerful heating capacity. The Heating Ring System is used to ensure the mold nozzles constant heating temperature.
Hydraulic Ejecting System -- Quiet, Long Service Life
Pudong plastic Preform Injection Mold adopts hydraulic ejecting mode to replace the mechanical type Hook Doffing System for smooth preform doffing process. The preform-doffing success ratio has achieved firm insurance and the whole preform ejecting process will become much quieter.

Cooling System
>> Short Cycle Time & Perfect Preform Quality In each inner mold part, there is well-designed cooling system with perfect cooling effect and abundant strength.

Low Preform Eccentricity
>> Leave Preform Eccentricity Away
Self-lock System Long bi-awls (double-taper) fixed orientation advanced techniques has been adopted on Pudong plastic Preform Injection Mold to reduce the preform eccentricity problem caused by outside reasons.

Patent Designed Rectifying System for Preforms Eccentricity -- Double Insurance on Preform Eccentricity
Patent Designed Rectifying Device has been equipped on Pudong plastic Preform Injection Mold to remove preform eccentricity possibly occurs during preform production. After rectified, the preform walls eccentricity can be adjusted below 0.05mm again.

After-Sale Service
>> Have a good sleep Before delivery, each mold will bear strict test. Detailed parameters will be recorded with their own sole serial number. And full set of enough spare part will be equipped with mold to ensure molds normal working. Moreover, during molds using period, Pudong plastic ensures abundant normal spare part supply for any requirement. Pudong plastic helps you solve all the problems happened during production.
