Which company in China is better to do hot runner systems???

First of all, I am a professional hot runner. I think you have to pay attention to a few points when buying a hot runner, and I have listed them as follows around the cost performance.

**——The highest** may not be able to buy the best, and the lowest** must not be able to buy the good, everyone understands this truth, so we have to make comparisons and shop around. The same material, using the same accessories, why is it different, because some hot runner companies can't produce and process by themselves, and even don't have their own equipment. Another reason is that the high advertising cost leads to the high level of the product.

Maintenance – Mold is a wear and tear piece of equipment, it is not unlimited. Subsequent maintenance costs, you have to take into account. There are many manufacturers who don't make money by selling machines, but they can maintain them, and they make huge profits to the point that they feel afraid.

A problem that could have been solved as small as tightening a screw, they want you to replace the parts.

Cooperation - Once a company is chosen, it will basically cooperate with the company for a long time, without major problems, and generally will not easily change equipment manufacturers. Therefore, when choosing a company, we should pay attention to the strength of the other party, and how to judge the strength of the other party mainly depends on the other party's machinery and equipment. The other party's processing workshop, production workshop.

Because the instability of a small business will directly affect your normal production.

At present, the more well-known brands in China are:

Best, Max, Hengsu, Cronning, Xianrui, Arnold, Hengdao, Sinak, Haotes, Max, Gruntai, Yudu, Master, Synventive, Haosu, Xianrui, Xinhao, etc.

Best, Tengsheng, Max, Hengsu, Cloning, Xianrui, Arnold, Hengdao, Sinak, Haotes, Max, Grid, Yudu, Master, Synventive, Haosu, Xianrui, Xinhao,

In different fields, such as the automotive industry, Hengdao Technology, Haote, Maishide, etc., different industries, different manufacturers.

The domestic hot runner technology has become mature, if you only do it in China, and there is no difficulty in the hot runner, you can choose a company in China. As long as the after-sales service can keep up, it is not a big problem.

If you export, you have to choose a brand that has an after-sales point abroad, and there is no after-sales point abroad, which is a hard injury.

For difficult hot runners, it's better to find big brands, big companies have stronger R&D capabilities, and you can see your incredible products here.

It's hard to say, it's hard to say about the top ten in the world. There's no way to do rankings.

For example, 64 mouths, 128 mouths or more or higher difficulty can choose imported brands.

Hot runners have been developing for so many years, especially in China, and in recent years, they have been the most rapid, and many powerful manufacturers have emerged.

At present, the more well-known brands in China are:

Best, Max, Grunta, Cronning, Pioneer, Arnold, Sock, Haotes, Mozuo, Nan Fung and many more.

It is difficult to rank, because each company is good at different fields, hot runner electronics, automobiles, packaging materials and other fields, can only be ranked from the comprehensive strength and influence of a company, but the implementation of specific products still needs specific analysis.

For products that are difficult and require a high level of craftsmanship, it is best to choose imported brands. After all, foreign countries started early, invested heavily in R&D, and the product stability was relatively reliable.

There are many hot runner companies that have grown up in China in recent years, and there are many strong ones, but in the end, the purchase of products still needs to be considered comprehensively. Product quality, after-sales service, etc.

Max, Gruntai, Yudu, Deent, Synventive, Master, Haha, you know so much.

The high-end quality of the current domestic well-known brands are:

Master, Saintventive, Blake, Xinhao, Incoo, etc.

The mid-range quality ones are: Best, Liudao, Cronin, Haotes, Mosaku, and so on.

This can't be divided like this, each company focuses on different areas! Some companies focus on the market and have average quality; Some companies pay attention to quality technology, and the market is a little worse!

It is mainly divided into engineering plastics, optical transparency, cosmetics, automobiles, and automobiles are also divided into very fine, multi-cavity, and stacked molds....

In the category of engineering plastic connectors, Chengao hot runner does the best!

Optically clear Best is made wide!

Cosmetics PETG is only made by Husky, and other companies make general rubber materials!

Car yudo is more experienced in doing it!

Maxford is too miscellaneous, and the quality is average.

Hot runners have the following advantages:

1. Molding cycle.

Because there is no limitation on the cooling time of the sprue system, the part can be ejected in time after forming and curing. Many thin-walled parts produced with hot runner molds can be made in less than 5 seconds.

2. Save plastic raw materials.

In the pure hot runner mold, there is no production waste because there is no cold runner. This is especially important for applications where plastics are the most expensive. In fact, the world's major hot runner manufacturers have developed rapidly in the world's most expensive oil and plastic raw materials.

Because hot runner technology is an effective way to reduce material costs and reduce material costs.

3. Improve product quality.

During the hot runner mold forming process, the melt temperature of the plastic melt is precisely controlled in the runner system. Plastic can flow into the cavities in a more uniform state, resulting in a part of consistent quality. The part gate formed by the hot runner has low residual stress and small deformation of the part after demoulding.

Therefore, many high-quality products on the market are produced by hot runner molds. For example, many plastic parts in familiar Motorola mobile phones, HP printers, and Dell laptops are made of hot runner molds.

4. It is conducive to production automation.

The workpiece is a finished product after being formed by the hot runner mold, and there is no need to trim the gate and process the cold runner. It is beneficial for production automation. Many foreign product manufacturers have combined hot runners with automation to greatly improve production efficiency.

5. Expand the application area.

Many advanced plastic molding processes have been developed on the basis of hot runner technology. Such as PET preforming production, multi-color co-injection in the mold, multi-material co-injection process, stack mold, etc.

The hot runner is heated to ensure that the plastic of the runner and gate remains molten. The hot runner system is generally composed of several parts, such as a hot nozzle, a manifold plate, a temperature control box and accessories. There are generally two types of thermal nozzles:

Open thermal nozzles and needle valve thermal nozzles. Since the form of the hot nozzle directly determines the selection of the hot runner system and the manufacture of the mold, the hot runner system is often divided into open hot runner system and needle valve hot runner system.

Summary. Okay, pro, nozzle material, no post-processing, so that the whole molding process is fully automated, saving working time and improving work efficiency. 2.

Low pressure loss. The temperature of the hot runner is equal to the nozzle temperature of the injection molding machine, which avoids the condensation of the surface of the raw material in the runner and the injection pressure loss is small. 3.

The reuse of nozzle material will degrade the performance of plastics, and the use of hot runner systems without nozzle material can reduce the loss of raw materials, thereby reducing product costs. 4.In the cavity temperature and pressure uniform, the stress of the plastic parts is small, the density is uniform, under the small injection pressure, the short molding time, the injection molding is better than the general injection molding system, for transparent parts, thin parts, large plastic parts or high-demand plastic parts can show its advantages, and can produce larger products with smaller models.

5.The hot nozzle adopts standardized and serial design, and is equipped with a variety of optional nozzle heads, which has good interchangeability. The unique design and processing of the electric heating ring can achieve uniform heating temperature and long service life.

Hope mine can help you.

I'm still a little confused, can you be more detailed?

The unique design and processing of the electric heating ring can achieve uniform heating temperature and long service life. I hope I can help you with this Sakura Tour.

There are too many foreign countries and there is not necessarily a market in the country, and the more well-known brands in China are:

Youdu, Max, Gretai, Cronning, Xianrui, Arnold, Sock, Haotes, Mozuo, Nanfeng and so on.

No hot runner is perfect, and it is recommended that you can judge it from technology, cases, and services.

First of all, you need to inspect at least 5 first-class businessmen, and judge the professionalism of the other party through information and interviews, especially some details at the implementation level (the requirements of finished products can be increased in difficulty, such as: wall thickness, materials, gates, cycles, etc.), and the process of asking more questions to the other party can completely see the ability of the other party.

Secondly, you need to understand the case introduction of the best businessman, especially the real case drawings and physical objects of your peers, the same material and the same paragraph, so as to judge the level of craftsmanship.

Finally, it is necessary to judge whether the other party's management is practical and reliable through the interview, you must know that the hot runner is not a disposable consumer product, there is a long-term after-sales problem, and the character, attitude and character of the business management personnel determine the after-sales guarantee in the later stage.

As for **, this is the key to cooperation, it is not recommended that you take **high and low as the focus of judging and matching, but you must understand the difference between **high and low respectively**, there is no low price or ** for no reason, the entire **chain system respects the pricing model of a penny price and a penny, so you need to judge the degree of adaptability to your and my needs by understanding the difference.

The above is my experience in selecting the best business, and the overall feeling is that it needs to be meticulous, communication, and cost-effective. I hope it helps

Can it be all advertising when you ask this, and the general products are OK if they are made in China

Now there are more and more people doing bai hot runners, and some of them are just a hot runner company, willing to throw money on the network, and it looks quite big on the Internet. In fact, the network is false, I want to see the essence, and I will tell you a few necessary conditions for choosing a company, and attach some company and personal opinions that have been assessed below.

Due to the differences in the conditions of hot runner manufacturers (each has its own advantages and disadvantages), there must be an objective scoring item as the basis for selecting qualified hot runner suppliers.

Therefore, the hot runner supplier audit should develop a detailed audit content, which usually includes the following items.

The operating conditions of the hot runner business. It mainly includes the history of hot runner business, the amount of registered capital, the number of employees, and the main customers. (This is the most important thing).

The production capacity of hot runner merchants. It mainly includes whether the production equipment of the hot runner business is advanced, whether the production capacity has been fully utilized, the space distance of the plant, and whether the manpower for production operations is sufficient. (This is basically to see if there is production equipment).

Yudo, Deent, these hot runner manufacturers are not bad, I have been in contact before, if you are interested, you can go to the official website to take a look.

1.Hot runners reduce (or no) cold material, saving raw materials.

The improvement of the stool technology makes it easier to inject the product into the source of land plastic and improve the product quality.

Under the same conditions (injection molding machine size, etc.), the hot runner can inject larger and more difficult products.

More conducive to automation.

Increase productivity.

Energy saving (reducing the process of processing cold runner rubber, cracking brigade, etc.)
