There are several kinds of hot runner in the world. They have different price and quality. We can call the brands such as Mold master, Thermoplay, Yudo,Synventive, and so on.

For your company, which kind of hot runner you or your company prefer to use?

If you can tell the advantages in details, it would be highly appreciated.

Thank you.

We leave it up to the customer, manifold issues are separate in our T & C when it comes to guarantee.

I can say that lately, I'm assuming due to internal restructuring, timely engineering and technical support has been difficult from Husky and MoldMaster.

There are many "flavors" of hot runners. They should be spec'd as application specific. You should look at the manufacturer's successes and failures within the types of applications you are tooling. None of the manufacturers are my choice across the board. Some large manufacturers will not touch some applications that another company can do successfully.

Some examples of system considerations are:
High cavitation commodity resins
Low cavitation commodity resins
Crystalline materials
High temperature amorphous resins
Engineered resins
Mold Base Size constraints
Injection Point geometries, (space between the drops)

Make sure your manufacturer is comfortable with your application, and do not accept "one size fits all". Also, make sure that you obtain and understand their pressure drop data and the molding machine capabilities before the system is constructed.

Hi Dirk,

Very good point.

But I am so confused. Some of my customer insisits in using Thermoplay hot runner. And he cann't accept other brands. It is quite strange. Normally, we use YUDO in domesic market. As you know, the cost is lower.And yes, sometimes, mold master also ok.

That's why I listed this topic. I wish to know more information from experts. :)

THANK YOU FO RYOUR INFOMRATION.

Running like types of systems is always an important consideration. When the applications are consistent, and the systems are capable within the engineering scope of the applications, it is the only way to go. Running "same brand" systems:

Reduces training and expertise costs to clean and repair a system.
Provides for common spare parts and utilities.
Provides for more consistent processing across the range of applications in an organization.

However, it should not be the determining factor when an application falls outside or to the edge of the capabilities of the manufacturer.

Your customer probably understands the Yudo system is cheaper. But please understand, the higher initial costs of the system may be more than offset by lifetime costs for your customer to run the system.

Good luck with your customers, and hopefully this explanation clears up some of the confusion.

Manifold systems, I am a big supporter of Synventive Molding Solutions, not because of their systems designs, but because they listen and care about the customer. They design system that will work for the application, and I had some wild applications for them. Plus when I call them with an issue, they will resolve it. For example: I called one time on a Saturday late afternoon 4:30 PM, because of an issue that we caused ourselves, 6 broken valve gate pins. I had to get a tool shop to open up too, Syventive came in with parts in hand, we did the teardown of the tool, (they help) recut and shape the pins, and reassembled the mold ( not their job) and had it back up and running by 11:30 PM...That why I use them, that is why I will always use them...Because I can count on them. They know customer service is more than a cheap price or a cool presentation. I have not see such efforts ofof most of the other suppliers, the other one I have good memorries of is Softline, because of their efforts and service. Their service improved greatly after we able to gain of what was expected..

Dirk made a very good match to your question. Anyhow for thin wall parts and disposables, without any doubt I would prefer to use Mastip.

Listen to Mike. Customer service often gets paid lip service, and pure price wins out. We get paid to bring the best value at the lowest possible price. When you add all of the costs, more often than not the type of service Mike talked about wins.
