September 2017

As September is soon coming, there will be a colorful backdrop to the countryside as the leaves turn from green to vibrant red, orange and yellow. Football is starting to be played on the weekends.

Many industries will be tooling up for new products during this time. Especially in the plastic injection molding community. With an increase in off-shore molders, it is more important today to put your company in a competitive position. As you know, how you design and develop the injection mold will be a factor in how efficient the tool operates. As mentioned in last month’s blog, cycle time and material used will greatly influence the total cost of delivering parts to your customers.

If you are in the process of designing a new injection mold tool, feel free to use FISA as a resource to help with the design of the hot runner system. Our in-house Engineering department has many years of experience and can design an efficient plastic delivery system that will give you years of production with minimal downtime. Brian Robison or Marc Wardell will be happy to provide the hot runner nozzles with the appropriate type, size and gate for your application.

You can contact our engineering department by phone (931) 222-4351 or

I hope you have a chance to enjoy the color of nature’s Autumn, your football teams win and you will contact Brian or Marc as a resource for your hot runner needs.

On the outside, it seems like we sell FISA hot runner systems, also known as runner less mold systems.
But is that really true? I like to think we sell service and savings to our customers.


Material. Plastic may be cheap unless you are producing plastic parts…. Over the life of the tool, a few pennies saved per part can add up to HUGE savings. No runner, no wasted plastic. Oh, but you use a granulator and re-grind your plastic, right? How much does that grinder cost compared to a hot runner system? How do you separate your parts from your runners? Conveyors? Sprue Pickers? More cost again…. not to mention more peripheral equipment that can break, and the noise of that grinder…. can you say hearing protection? How about color matching with regrind? Regrind will throw off your colors, and because it’s already been through the plasticizing process, the plastic has lost some of its qualities.

Cycle time. As a plastic molder, you’ll need a certain number of parts per hour just to break even. There is the cost of the plastic, do you trim the sprues? Well, labor is very expensive as I’m sure you know. The overhead of the press, electricity, the building, the operator, office people, fork lifts… you get the picture. Any reduction in cycle time will drastically increase profits.

So why wouldn’t you want a process that makes just the parts? The FISA system is a valve gated system that has been around for almost 40 years so it is proven. I know, I know, very few of you have ever heard of us in North America. Well, I’m making it my mission to change that. It’s a great product with the best service. It’s simple and it works! Now I know you can cut a cold runner and/or a sprue into your new mold and it will run just fine, but what will that cost you in the long run? Other systems use hydraulics or pneumatics to operate the valve. The FISA system uses just a spring and the pressure of the plastic for operation. We will probably save enough in mold height steel alone over the other systems to pay for a FISA system. Give us a call or send us an email to see how we can help streamline your operation and increase your bottom line. We have a complete inventory of all standard parts and can ship in 1 day whether it is spare parts or complete nozzles.

July 2017

Summer is a time to enjoy many outdoor activities. Hiking trails, floating rivers, taking road trips, visiting theme parks, camping to name a few of these activities. It is a chance to unwind from your daily grind, to create family memories, or just to enjoy friends and family.

With a few precautions, these activities can be safely enjoyed. If you are camping or hiking make sure you have plenty of water to hydrate with, a basic first aid kit and some insect repellent. Take plenty of sunscreen if you are outside, even on cloudy days you will need UV protection. But most important don’t forget your Smore’s kit.

When you are driving to your destination, keep your speed down, those white signs along the way are not suggested speeds. Be aware of the distracted drivers that may try to share your lane. Play travel games with the children during the trip. Many times, the journey is as enjoyable as the destination.

We at FISA Corporation want you to enjoy your well-earned vacation and know that when you return we will have a full stock of standard Hot Runner Nozzles and spare parts to keep your injection molds making the best parts possible. Please contact us with any questions or quotation requests.

Summer is right around the corner and many molders will have a summer shut down as a time for refreshing and recharging for most people. However, for the people that keep the tools running that make the plastic parts, this is the time to schedule tool repairs. Included in the repair of the tools is the inspection and or replacement of the hot runner components.

Evaluation of the heaters and thermocouples.
Ring and cartridge heaters should be examined for frayed wiring, damage to the metal case, and loss of the wire seal on cartridge heaters. Frayed insulation may be repaired with high-temperature electrical tape. If the conductor wire or metal case is damaged, the heater should be replaced.

Thermocouple examination is for frayed insulation, kinks and crushed areas on the metal sheath. As with the heaters, frayed insulation may be repaired with high-temperature electrical tape. A thermocouple with kinks or crushed metal sheath should be replaced.

FISA Corporation keeps a large assortment of heaters and thermocouples along with all the standard components required for the complete rebuild of the hot runner nozzle drops in stock in Tullahoma, Tn. Please contact us with any questions or quotation requests.
