Did you know that hot runner system is an environmentally friendly technology?
Hot runner system?
Cold runner system?
How are the plastic products we use in our daily lives made? Simply put, through the production of plastic products injection molding machine and connected to the injection molding machine to melt the raw materials, and then into the liquid raw materials into the product mold, and then cooling into the product, the product used in our daily life will come out. The industry calls it the "cold runner" production method.
Hot Runner System
Keep the embryo hot,
No head or handle

Let's find an example from around us to make it easier to understand.
When you look at a prefabricated plastic model, you may see small
parts attached to handles that, when removed, create a lot of waste.
Cold runner method is to manufacture products in this form.

All kinds of industries produce plastic waste.

Therefore, when using the cold flow method to manufacture products, after the product ejection, in order to remove the generated waste, it is also necessary to carry out a follow-up process. It would be nice if all this removed waste could be recycled, but unfortunately, there's only going to be more of it. In addition, the cooling of raw materials also takes a long time, and the production time is extended. Therefore, the use of cold flow method to produce products will reduce production efficiency, increase energy consumption, and thus emit more carbon.
So why use cold runner to produce products?
The main reason is that the initial cost is cheaper than other methods. However, in the long run, we cannot ignore the raw materials and energy wasted in the production of products. Considering the secondary costs of waste disposal and recycling, it cannot be said that using cold runner is cheaper.
What about introducing hot runner technology?
What about the hot runner system? Hot runner method is a technique used to make up for the defects of cold runner system. Unlike the cold runner method, the hot runner does not waste raw materials or generate any waste during the production process.
The use of the TSHOT hot runner system reduces plastic raw materials by approximately 33%
This is because the part of the product that is injected into the raw material will always remain in a liquid state and will not produce a handle. Therefore, only the raw materials required for the product can be used, the amount of raw materials is reduced, and continuous injection molding can be carried out. Hot runner also drastically reduces cooling time. It also does not require additional processes to remove the waste, so it will reduce some of the factors that pollute the environment, such as carbon emissions, and also reduce unnecessary energy consumption.

Helping customers make
choices is also TSHOT's mission
Plastics are unavoidable in environmental problems. But can we live in a world without plastic? If plastics are essential in our daily lives and cannot be replaced immediately, TSHOT will play a leading role in guiding people to the proper production and use of plastics through steady research and development.
We also work with other companies that share these ideas and values to solve environmental problems. TSHOT will always strive to find the best ways to strengthen our role in helping to transform the plastics industry into a sustainable one.
