detailed introduction
- Professional team precision processing
A.Our mold features
1. The template is pre-hardened P20 steel or 4CR13 steel.
2. The core, cavity and neck screws are made of S136 high-strength anti-corrosion stainless steel, which is better than 48HRC.
3. The template is finished by one-time processing to ensure the concentricity of the forming retainer and the guide bushing, thus ensuring the compact structure of the mold.
4. The opening and closing pull plate (material S136) adopts the bearing slide type to descend, and the performance is reliable. It is a highly integrated process of slider, push plate and eject. All sliding parts are inlaid with self-lubricating copper alloy to ensure low friction coefficient and strong wear resistance.
5. The main components are of the same brand as HUSKY, with high positioning accuracy and easy disassembly and assembly.
Reasonable and fast spiral circulation water circuit can cool down quickly and shorten the cycle time.
6. The double-cone positioning principle is adopted to ensure high manufacturing accuracy, so as to ensure that the products do have defects such as flash, different sizes, and irregularities.
7. Neck screws are processed by famous brand equipment. Accurate and consistent size
8. The hardening of the molded parts makes the friction surface stable, the same and durable.
B. Our hot runners Advantages
1. Reduce the loss and cost of raw materials;
2. Reduce the recycling, sorting, crushing, drying and storage of waste, which can reduce the number of pulverizers, save labor, reduce energy consumption, and save production space;
3. Avoid the impact of using recycled materials on reducing the quality of parts;
4. Ensure the consistency of injection molded parts and improve the precision of plastic parts;
5. Increase the injection volume of the part and improve the compressibility of the plastic melt;
6. Strengthen the function of injection and improve the injection molding process;
7. Reduce the required injection and holding time;
8. Reduce the required clamping force;
9. Shorten the mold opening stroke in the injection operation cycle and eliminate the time spent taking out the nozzle material.

Our advantage
- Guarantee of quality and service
design team
precision equipment
testing and proofing
High quality mold parts
- No cold glue, glue leakage and wire drawing at the preform gate
- Double cone positioning ensures the coaxiality of the molded parts
- The eccentricity of the preform is controlled within ≤0.15mm
- The weight tolerance of each preform is controlled within ±0.2g
- The guaranteed life of the mold should be more than 3 million molds
Four-step ordering
- Professional and responsible and quality control
Clear requirements
- Bottle preform size meets production requirements
Before placing an order, clarify the preform data, including the diameter, weight, and tolerance range of the preform, and determine whether it is an exclusive preform or a common preform in the market, and customize the design according to needs.
Design solution
- customized to meet market requirements
We provide detailed design drawings or design according to your sample bottle preforms to ensure that the diameter of the bottle preforms meets international standard data, can match the cap, and meets the production standards of the bottle blowing machine.
Mold processing
- choose high-precision processing technology
We confirm the mold manufacturing process, material selection and processing time with you to ensure the durability and production efficiency of the mold. High-quality molds can significantly improve production efficiency and reduce long-term costs.
Sample Verification and Delivery
- Ensure Product Qualification
After the mold is completed, we will make samples and provide you with 500 bottle preforms for production testing. We will conduct a three-party quality inspection to ensure that the preforms are qualified, and at the same time ensure the delivery time and update the progress with you at any time.
that's what they say
- Solving problems for customers is our aim
I just entered the preform industry five years ago. There were a lot of pitfalls at the beginning. I have encountered merchants with no after-sales service. The purchased preform mold cannot be installed, and the design of the preform produced by the purchased mold is unreasonable. , the reject rate is high, and the caliber error of the preform produced is large. Until I found Vivivan, she helped me solve technical problems and provided professional techniques. Now I not only buy molds from her, but I also feel that I have an extra partner in China.
