Cutting and Other Finishing Processes for Stainless Steel Hypodermic Tubing Requires the Right Equipment

Whenever you are cutting sections of stainless steel hypodermic tubing, you have to be careful to not crimp the ends. If you accidently crimp the ends, the tubing will not perform correctly. There are specific kinds of tools which can be used to ensure the proper cut without causing crimping. After the tubing has been cut, you may also need to debur the ends, so that they are smooth. Further, during deburring processes care has to be taken to ensure the ends of the tubing remain even. Another type of finishing process you might have to perform could be bending the tubing to a desired angle. Bending requires precision equipment to avoid kinking the tubing or breaking it in the location of the angle.

In the event you are having problems with completing finishing processes on your own, or lack the proper tools and equipment, you have other options available to ensure you receive the proper stock of tubing. For instance, we offer many of these secondary services to help you obtain hypodermic tubing precisely cut to your specifications and project requirements. We are also able to take care of deburring, cleaning, and bending the tubing to the desired angle. For applications that require small precut sections of tubing in one, two or three inch lengths, we carry regular-walled tubing ready for order without having to request additional secondary options, as well as one and two inch cut lengths of hypodermic tubing with 90 degree bends.

One Type of NiTinol Wire Used for Various Applications Is Super Elastic

There are differences between NiTinol wire, so it is important that you select the right kind for your projects and applications. One type available is called super elastic and provides the ability to recover to a specific diameter after being pulled and stretched. The super elasticity of the wire has a narrow temperature range between its original shape and the deformed shape to which it is stretched or pulled. In order to return the wire back to its original diameter, it has to reach its transformation temperature. Because this range is so narrow, there is often no heating required to cause the wire to return to its original diameter.

Super Elastic NiTinol Wire Can Be Used in Place of springs and for Switches

Super elastic NiTinol wire has a vast elasticity, greater than most types of metal springs, that can be up to 30 times greater. As a result, this wire works well within products and materials where springs are required. Due to the ability of the wire to be deformed through stretching, it is able to return back to its original shape once it reaches the transformation temperature. This kind of wire is also able to be used for switching mechanisms in different ways. For instance, the wire could be stretched and used to hold a pressure switch plate in place. Upon an increase in temperature, the wire returns back its original diameter, and, at the same time, releases the pressure plate switch. This is just a simple example of how the wire is able to be used, as there are numerous other ways, depending upon your exact applications, processes and requirements.

Filtration and Drying Screens Are Two Uses for Polyester Mesh

Polyester mesh screening is used for a variety of purposes and applications, depending upon the industry. For instance, the mesh screen can be attached to a frame and used as a drying mechanism for products and materials. The openings in the mesh screen allow for air to flow all around the materials and ensure they dry evenly. Another use for the mesh screen in the food industry is to use it as a filter in the production of fruit and vegetable juices. The screening acts as a barrier to remove pulp, seeds, and skins from the pressed fruit or vegetables, while allowing the juice to pass through the screen. Other food industry applications for this kind of mesh include using it to sift flour and in processing refined sugars.

Polyester Mesh Is Used for Industrial and Research Applications

Polyester mesh has many features which are beneficial for industrial and research applications. This type of mesh provides decent abrasion and corrosion resistance, has a high tensile strength, and performs well when exposed to wet environments. In addition to being used for filtration and as drying screens, this mesh can be custom cut and sewn into mesh bags. The mesh bags are used where different materials are placed inside in order to control their release over an extended period of time, like for releasing fertilizers used in agricultural applications. Laboratory and research facilities occasionally use this kind of mesh as containment for insect studies, as air is able to flow through the openings while keeping test subjects enclosed in the desired locations.

Companies Use a Blunt Needle to Control Fluid Delivery Processes

There are different ways in which you can control and regulate fluid, adhesive and liquid delivery during your production processes. Ensuring the proper levels is applied to each part and component is necessary in order to maintain product quality and prevent waste. If too much or too little fluid, adhesive, or liquid is applied, it results in products that have to be rejected, and increases your waste costs. One method frequently used is to use a blunt needle as a dispensing tip connected to a syringe, bottle or automated delivery equipment. Because the fluid, liquid, or adhesive can be properly measured, the right amount gets applied.

A Blunt Needle Is Offered in Standard and Custom Sizes

A blunt needle is available in different wall thickness and gauges depending upon your own requirements and specifications. You are able to find regular wall, thin wall and extra thin wall tubing attached to polypropylene luer hubs. In addition, the lengths of the needles are offered in standard sizes, including half inch, one inch, and one and a half inch. In situations where you require a needle of a different length, you can utilize our secondary finishing processes to have your needles customized. These processes may also be used in situations where you require the needles to be bent to a specified angle. It should be pointed out that extra thin wall and thin wall needles are more difficult to bend than regular wall needles. This is not to say it cannot be done; it just might require additional finishing time to ensure the quality of each needle is maintained.

FEP Shrink Tubing May Expand in Length as It Shrinks

When working with FEP shrink tubing, you need to remember that the tubing can expand as it shrinks. For this reason, you want to make sure you cut the FEP tubing to the correct length. Leaving a slight overlap on both ends where the tubing is going to be applied does not have to be excessive. For instance, if you are repairing a three inch section with the tubing, you might only need to use a three inch section of FEP tubing, because it may provide sufficient overlapping once it is shrunk and expands in length. Prior to applying the shrink tubing on a large scale, it is worth your time to experiment to determine the best size to use, and make adjustments to fit your requirements and specifications.

Pharmaceutical and Laboratory Applications Use FEP Shrink Tubing

FEP shrink tubing is used for a variety of pharmaceutical and laboratory processes and applications. Just like PTFE shrink tubing, FEP is chemically inert and provides high lubricity. However FEP has a much lower shrinkage temperature, so it is better suited for situations and applications where mid-range temperatures are in use. Further, FEP tubing is able to be autoclaved, using gas or steam processes, when required. FEP tubing is available in a variety of diameter sizes and is offered in standard four foot sections. However, for businesses that do not want to have to cut their tubing to frequently used lengths, they may take advantage of our secondary finishing processes to order the desired quantities of tubing already custom cut to the desired lengths.

Fastening Options You Can Use with Stainless Steel Machine Screws

There are different ways in which you are able to ensure stainless steel machine screws remain firmly in place. The screws do require a predrilled hole before they are attached to your various components and parts. One option for holding them in place is to make sure the predrilled holes match the size of screw you are using. If you drill the holes too big, the screw will not fasten correctly. As long as the hole is the right size, the use of nuts is often not necessary, as you are able to fully tighten the screw. Another option is to apply a small amount of adhesive or glue into the predrilled hole prior to inserting and tightening the screw. Once the glue dries, it helps to hold the screw in place and prevents it from working loose. Using glues or adhesives as a fastening method is ideal for products where the screws are being used in areas that can be affected by vibrations or movements from the finished product.

Government Projects Require DARFs-Compliant Stainless Steel Machine Screws

Government and military projects require that certain materials and products be able to pass regulations and compliances. For instance, stainless steel machine screws require Defense Federal Acquisition Regulation Supplement (DARFs) certifications. These certifications ensure each and every screw satisfies specific acquisition requirements, such as their country of manufacture. Whether you are a government contractor, or a government agency, we are able to provide DARFs-compliant fasteners for all kinds of defense projects.

Medical Devices and Pharmaceutical Procedures Use Straightened Wire

Straightened wire is commonly used both for pharmaceutical procedures, as well as in the manufacture of medical devices. This type of wire is available in small diameters and is designed to pass through the interior of certain gauges of hypodermic tubing. When used in this manner, the wire becomes part of a guide wire assembly. Guide wires are frequently used to push another object to its desired location through the hypodermic tubing. For example, in procedures where a stent needs to be inserted, the stent is placed inside of the hypodermic tubing and the wire is used to guide it into its desired location. This same process is also used for other purposes, such as passing small electrical or sensor wiring to specific locations during assembly processes of sensitive surgical and medical equipment.

PTFE Coatings Can Be Applied to Straightened Wire

In addition to being passed through the interior of hypodermic tubing, other types of materials may be used along with straightened wire. For example, PTFE coatings can be applied to the exterior of the wire in order to help increase their chemical resistance and lubricity. Coating thickness ranges from 0.00016 inches to 0.00039 inches and comes standard in green. Other colors are able to be procured, including blue, black, white, and clear, via special order. Available diameters include 0.005, 0.006, 0.009, 0.011, 0.013, 0.015, and 0.019 inches. Further, most diameters are also able to be passed through various gauges of hypodermic tubing, should your applications require using coated wire in place of uncoated wire.

Hypodermic tube is available in a variety of sizes ranging from 5 gauge to 36 gauge. This type of tubing also is supplied in three different wall sizes to fit with your specifications, including regular wall, thin wall and extra thin wall. Tubing comes standard in thirty and sixty inch lengths with secondary finishing services available to customize tubing to fit with your own specific requirements.  In situations where you frequently use one, two or three inch lengths of this tubing, you are able to order it already cut to the desired length and keep a stock of it on hand. There is also one and two inch legs of tubing available already bent to a ninety degree angle. In cases where you use a variety of sizes and wall thickness, you are able to help keep them organized and undamaged by storing them in round plastic storage tubes.

Different Applications and Uses for Hypodermic Tube

Many different pharmaceutical and industrial processes use hypodermic tube for various applications and processes. For instance, one common use is to pass straightened wire through the interior of the tubing when it is being used as a guide wire assembly. Another purpose for the tubing is to have it cut to custom lengths and attach it to polypropylene luer hubs in order to create dispensing needles. Dispensing needles are used to deliver fluids, liquids, glues, and adhesives in desired quantities, depending upon the desired application or process. You are also able to use hypodermic tubing adapters along with standard compression fittings in order to connect this kind of tubing to plumbing circuits.

Items to Consider When Ordering Hypodermic Tubing

When selecting hypodermic tubing for your applications, you need to determine the gauge and wall size you require, as well as the overall length. Gauge sizes are easy to get confused, because you might assume, as they got larger, so would the diameters on the tubing. However, this is a common mistake many people make, as this is not the case. Instead, as the gauge sizes increase, the diameters actually decrease. In order to avoid making this error, it is better to determine the diameter required, and then use that measurement to determine the appropriate gauge size.

The wall size is another factor that has a direct effect on the inner diameters of hypodermic tubing. As the wall becomes thinner, the inner diameters increase. It is possible to find inner diameters which are relatively close to one another, but that have different wall sizes and gauge sizes. For instance, 11 gauge thin-wall tubing has an inner diameter of approximately 0.098 inches, while 12 gauge extra-thin-wall tubing has an inner diameter of approximately 0.099 inches. Either one of these may be suitable for your desired applications, but it is worth your time to obtain a small sample of each one and conduct some tests to determine how each one performs. The final thing you need to determine is the length of the tubing. Tubing is offered in standard lengths of 30 and 60 inches, and can be custom cut to your exact specifications using our secondary finishing processes.
