Preform mold introduction
- insist on good quality
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
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.
We're There Every Step
- Your order, my quality assurance
Preform design
Good design is the key
Good preform design can reduce scrap rate and production cost. If you are a preform factory, a good preform design can make your preforms suitable for more customers’ bottle production and increase sales.So we communicate with you in detail, and then carry out the preform design.
modeling
Mold structure is the guarantee of life
A good mold structure can not only ensure the smooth progress of production, but also reduce labor costs and increase the service life of the mold. We have 20 years of experience in preform molds, which can avoid some misunderstandings and make the yield and life of the mold better.
Mold processing
Guarantee of high precision
We use Hardinge CNC lathes to process cores and cavities to ensure the consistency and interchangeability of each core and cavity. The mold base is processed by a large CNC milling machine to ensure the precise fit between each hole and the mold core.
mold parts
HUSKY quality
Our mold core and cavity are made of FS136 high-strength corrosion-resistant stainless steel, and the heat insulation cap is made of American DuPont material. The nozzle is made of Ambrox beryllium copper to prevent the preform from turning white and yellow.
Mold assembly
Complete assembly and testing
We assemble bottle preform molds with utmost precision and expertise. Each component is meticulously crafted and fitted together to ensure flawless functionality. Our commitment to excellence is evident in every mold we produce.
pack and ship
Wooden packing
We use customs special wooden box packaging to ensure the completeness of the mold, the best sun protection and moisture resistance, and choose high-quality freight to ensure the safe arrival of the mold.
our difference
- One stop solution
JinDong factory has been engaged in the blow molding industry for 20 years. Our main products are bottle blowing machines, blow molds and preform molds. We are one of the earlier factories of PET plastic machinery in China, and we are the designated supplier of famous enterprises in China. We have provided products, solutions and services for 2000+ customers in 20 years. Why we are different from ordinary blow mold factories, because we not only produce blow molds, we also produce blow molding machines, we have more actual blow mold production data than most mold factories, and the molds we design are more Material saving, high bottle yield, strong durability, choose us, not only save your time, but also save your money. Let professional things, please leave it to us, you just need to tell me your needs.

- customer love
I think injection molding is much more difficult than blow molding. Most of my workers are new to blow molding, but they can basically master the blow molding machine within 7-10 days, but injection molding requires long-term experience accumulation. The Jindong factory provided me with such convenience. They gave me a lot of experience, which greatly reduced the difficulties of the workers in our factory in the operation of the preform mold. I am very happy that we will continue to cooperate.

It is not easy to find a preform mold factory with high quality, good service and reasonable price. The cooperation between me and Vivian is very good, and the Jindong factory is trustworthy. The advantage of Jindong factory is direct access to the factory, which can quickly find and deal with problems, and avoid the same problem in the future.
Frieda
The preform has too many calibers. As a novice purchasing assistant, I do have a headache. Every time the CEO asked me a question, I would consult Vivian first, and she helped me a lot. We have successively ordered 5 sets of preform molds and 9 sets of blowing molds from her. During this period, we communicated a lot. We are all young girls with many topics.
Ebenezer
Our factory has been purchasing preforms in China before, but with the increase in sales, the cost of purchasing preforms for a long time is very high. I thought of the idea of producing preforms by myself, I thought of Vivian, she helped me make the whole plan of blow molding, and within 3 months, I produced my own preforms.
