JDL Enterprises

We are an innovative company committed to providing superior quality customer service; shut-off valves, shut-off nozzles, and specialty plastic injection products.


About Our Injection Molding Products

In the early 1990’s JDL was challenged to produce a shut off nozzle for the gas assist industry. Beyond the use of nozzles in standard injection molding, our engineers developed a low cost positive Rotary Resin Shut Off Nozzle, working directly with many gas assist suppliers in complementing this function in nozzle insertion.


Based on this success, a new challenge was to produce a smaller version which evolved into the Universal Shut Off Nozzle. With these devices now available, gas assist nozzle injection can be preformed on any molding machine. Actual use has been on machines ranging from 25 ton up to 11,000 ton. Our Rotary Resin Shut Off Valve IV was developed to stand up to pressures utilized in conventional injection molding. If you have a need for a reliable shut off nozzle for gas assist molding, standard injection molding or structural foam give us a call!

High Quality Injection Molding Components

At JDL, we are always on the hunt for more ways to make our products unbeatable.  Whether it's utilizing smaller presses, achieving faster cycle times, working with more versatile tooling, or reducing labor intensive secondary operations, we're dedicated to finding the best way to produce what customers want, not just a rough prototype but sophisticated products, that won't' require repair later.


Injection molding is a process that requires considerable design and engineering work and our clients use a wide variety of machines. They also have to determine whether the equipment and processes used have the durability and pressure to produce the desired result, or how to use alternative molding methods to save money or produce differently engineering parts that are more valuable to a client's process.


For example, using nitrogen gas techniques can help save money by decreasing the requirement for mold strength; these lower pressure methods can also turn out lightweight parts that are more portable or versatile for your customer. In turn, JDL provides devices, like check valves that prevent resin from entering the gas line, causing downtime and delaying delivery to your customers.

Superior Customer Service

With over 50 years of experience in the machining industry, JDL has spent the last two decades developing and creating revolutionary products for plastic injection molding and extrusion processes. We pride ourselves on our ability to deliver special orders to you on time, every time!


We also pride ourselves on excellent customer support, staying engaged through the process and evaluating whether the desired outcomes in proof-of-concept meetings or communications were achieved, and how a particular approach can save a client time and money. Turn to a company with a history of innovation in producing shut-off valves, nozzles, check valves, and tips for a wide variety of plastic injection molding machines, whether the machine is 20 tons or 11,000 tons. You'll be able to rely on our experience in counseling companies on what makes the most sense to get finished parts that will work well in production and out in the field. When it's time to find true solutions for injection molding, let JDL Enterprises help create parts for a modern, high-quality supply chain, and a successful business partnership.

    I have worked in the plastics industry for 26 years. In 1993, I was introduced to the JDL Rotary Shut Off Nozzle. Since then, I would only use or recommend JDL products to my customers. Anytime I’ve needed to supply my customers with special thread sizes or dimensions on any of the devices JDL manufactures, they come through with the best support I’ve experienced. The products JDL manufactures have superior quality and functionality for gas assist, conventional and extrusion molding.

    "I would like to congratulate you on the rotary shutoff nozzle that you have developed for us here at the Venture Groesbeck facility. The rotary shutoff nozzle has enabled to accomplish two things. One we have been able to control the drool on our hot runner jobs, and two, we have been able to decrease our cycle time on a large shot part. The long recovery time on the large part size was dictating a slow cycle time. With your shutoff nozzle we are able to run our screw as the mold is opening up, without any fear of material flowing out of the nozzle. I would also like to add that with the ¾" bore, we have not experienced any kind of pressure drop at all. We are able to continue running our molding process using the same pressures as before. Overall we are very satisfied with the performance of the rotary shutoff nozzle, and I thank you for all your support during the development of this product."

    "I want to thank you for the opportunity to test the rotary resin shut off valve for you. It has worked flawlessly. We tested it on an 850-ton injection press. Unlike the first units we purchased that leaked plastic, this one does not. The shut off valve has run on an 850 Natco for about 4 months, this being a 24 hr/7 days a week operation. The only problem I saw was the where the nozzle attaches to the valve needs to be 0.100 longer, the nozzle did not shut off completely. So this should be a good testimony to its durability.
