JD Blowing mold
- Free design, custom production
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.

design team
We have a professional design team of ten people. They all have at least five years of experience in PET bottle design. They not only have the ability to design, but also have experience in blow molding machine operation and mold manufacturing, so they can combine theory and production.
precision equipment
We have 15+ CNC machining centers, 5 precision CNC lathes, 2 gantry milling machines, etc. More than 95% of the processing is completed by precision processing equipment, which can guarantee the accuracy and accuracy of the annual mold to the greatest extent. accuracy.
testing and proofing
After the mold is completed, two internal alternate inspections will be carried out to ensure that the new mold can be installed and produced. We can provide partial proofing services to meet the different requirements of customers..
Sample room
We have a sample room of 300 square meters for testing and preservation of bottles produced by new molds. We can provide customers with some data for reference. Of course, we will not exhibit bottles with confidentiality agreements.

We're There Every Step of The Way
- It's easy to place an order with us
bottle design
Design the bottle you want and save money
According to the product in the bottle, first determine the bottle shape, choose the caliber and grams of the preform, and we will provide some professional suggestions according to your requirements to ensure high yield and low cost. After the design is completed, we will send the renderings and data diagrams of the drawings to you for confirmation.
modeling
According to your blow molding machine data
After confirming the bottle design, we need to determine the structure of the mold. Different blow molding machines have different mold structures. We will assist you to complete it and ensure that the data is accurate. The new mold can be installed in your blow molding machine for production.
cNC processing
Guarantee the high precision of the mold
We use CNC milling machines to complete more than 95% of the mold processing to ensure the precision of the mold. The mold is finished and polished so that the mold cavity takes on a mirror finish and the bottle finish is optimal.
Mold assembly
Complete assembly and testing
After the processing is completed, we assemble the mold and conduct inspections, including the consistency of the mold caliber and the preform caliber, the normal operation of the water transport, etc. We will make a sample of some molds and inspect the capacity and height of the bottle.
pack and ship
Wooden packing
Most of the molds are packed in wooden boxes, and some molds will be packed according to the selected foam board and carton. All measures are to ensure the safety of mold transportation.

that's what they say
- Solving problems for customers is our aim
Two years ago, I found three suppliers in China to make PET bottle molds, but the molds they made were not producible. The first mold couldn’t fit my blow molding machine, the second mold didn’t have cooling water channels, and the third mold had a high scrap rate. It wasn’t until I found Vivian that she used her expertise to help me solve all these problems and improve production efficiency. You might think that I only bought her molds, but no – I found a solution thanks to Vivian’s help. Thank you very much, Vivian.

It's hard to find good professional suppliers in China, I'm glad to know Vivian, she always solves the problem. Actually, I don't know many details about blowing molds, but she will tell me and provide good advice，and will avoid many pits.In short, I will purchase for a long time.
Jeff
I think the most important thing to make a bottle blowing mold is the bottle design and the structure of the mold. Vivian can do both well at the same time. Her molds are of good quality. I have more than 10 sets of molds and have been using them for 5 years.
Pape Toure
I made 15 sets of Jindong molds at a time, and the installation data of each set is correct, and Vivian assisted me in the installation, I am very satisfied. I will continue to cooperate.I believe her mold quality can not only save money but also worry.
