Preform Mold with Hot Runner System
Preform's quality and cost is no doubt one of the core issues in PET bottle production. It is also the most expensive part of the project. How to save the cost and to get excellent bottles? You may choose to buy preforms else where, but bear in mind preforms available in the market might not fit your bottle designs. Our preform mold will satisfy your demand as well as your budget. You will not be disappointed if you select us as your mold provider.

Features:
Customized Preform Design
We do custom design based on our more than 18 years experiences and knowledge in PET bottle industry. Every preform design is carefully tailored to fit its final bottle shape and specific application.
Preciseness
Apply Two-stage double-taper positioning technology. Each cavity is self-locked to ensure preform concentricity to avoid accumulated tolerance.
Superior Material
Top quality material (Sweden S-136, or German 2316 stainless steel) for cavities and cores to enhance the strength and durability. Equally super material for the remaining parts of the molds as well as the base plates, bushings and guides.
High Interchangeable Parts
All mold parts are processed by CNC machines. All cavities, cores, split neck inserts are properly heat treated and are interchangeable within same mold.
Hot Runner
Valve gated hot runner system is a proven winner for PET preform production. PID control makes cavities/nozzles with stable temperature and therefore yields excellent preforms.
Simplicity and Affordability
Simple does not mean lower quality and less function. Simplicity stands for less invest with high yielding. Fewer parts bring less maintenance, easy operation and lower price;
Flexibility
Possibility to make preforms with a few grams weight difference or neck finishing design change by simply replacing a few counterparts. This can be clearly viewed through the mold parts photo. The replacement core comes with flange which translates easy installation without affect the precision of the original mold.

Remarks
- A low pressure (0.6 – 0.7 MPa) air shall be provided to run the preform mold. This air compressor is not included in the mold price unless specified when ordering.
- A solenoid valve shall be connected to control the mold operation. This valve shall be installed in the injection machine. It is not included in the mold price/delivery. Please order the solenoid valve separately.
- A time relay (3/10 – 5/10 seconds delay) shall be installed on the injection machine to delay the injection beginning time after the nozzle valve stem opens. This time relay is not included in the mold price.
