Three shifts of operation result in unmatched capacity and rapid turn-around!
Laser marking is a computer-driven, environmentally friendly alternative to silk screening, pad printing, stamping, mechanical engraving, chemical etching, and many other costly, lower quality processes. Our high-speed non-contact process provides superior quality, permanence and design flexibility. Laser marking can achieve accuracy in small detail engraving unmatched by any other engraving method.
From ten to ten thousand, precision computer control means that your last production piece will look as good as the first!
Judson Smith offers the latest technology in fiber optic lasers to provide customers with a broad array of tools to meet their application challenges. Whether cutting, welding or marking, our in-house expertise provides customers with a wide range of manufacturing technologies.
Precision laser welding is a process of joining similar or dissimilar metals together without using additional filler materials. Our beam quality allows us to control the energy being delivered, resulting in minimal heat input, therefore avoiding any mechanical or thermal distortion.
A single laser pulse or a series of pulses causes the materials to heat up at the joining area until melting point is reached…almost instantly; a clean and uniform welding path is created.
Due to their short wave-length, Judson’s laser technology offers extremely precise cutting. Our four axis machines are capable of cutting multiple geometric and single wall features. The kerf width allows cutting diameters to be very small and accurate (.002″). The limited “heat affected zone” is essential when cutting thin wall metal tubing to eliminate any mechanical or thermal distortion. Contact us for more information on our laser fabricating capabilities.
Judson Smith also brings 50+ years of tube fabrication experience to solve our customers tube design and manufacturing challenges. Judson Smith not only fabricates tubes using standard “off the shelf” machines and equipment but also has the unique ability to design and build custom equipment to automate higher volume production. This capability minimizes the processing steps required to manufacture complicated tubing shapes and features and delivers significant per unit cost savings to our customers.

Expansion or reduction of the tube diameter is frequently employed to maintain a good balance between strength and length of a component.
Transitions are smooth and free of the interference that results from the use of adapter and coupling devices. Generally, the wall thickness of the small diameter section will be slightly heavier than the larger diameter.
To avoid added operations, the ratio of the Small O.D. / Large O.D. should be .7 or greater. However, by using multiple operations, the ratio can be exceeded.

The possible configurations of bent tubes are virtually unlimited. From the manufacturing point of view, the greater the bend radius to O.D. relationship becomes, the easier it is to produce a component with minimum distortion (ovality) in the bend area. This is also true relative to wall thickness, in that the heavier wall products generally bend better.

Beading can serve to provide a seat or stop on the outside of the tubular component. If the bead diameter is only slightly larger than the original tube diameter, a friction fit can be developed between the bead and the mating part. Since the bead is essentially free form, the shape is not easily controlled.
Subsequent to beading, thermal treatment may be required to relieve stresses and improve mechanical integrity.

Flared ends are commonly used as sealing surfaces; 37° flares, also known as AN fittings, required a backup sleeve and are normally used in high pressure applications.
45° flares, also known as SAE fittings, are commonly used throughout the automotive industry.
90° flares, also known as TRI-CLAPMS fittings, require a gasket and are widely used in sanitary applications where ease of disassembly is required for regular cleaning operations.

Notches in the tube wall may allow internal components to be viewed directly for positioning or assembly operations.
If the notch width exceeds I.D. minus 4 x wall thickness, the notching tool action must be tangential, rather than radial, to keep distortion of the tube to a minimum.
In parts under 2″ in length, Notching can be combined with tube cutting, for cost savings.

Judson Smith Company manufactures non-ferrous Seamless / Welded metal tubing with precision and quality. Our in-house tube drawing capability provides flexibility in custom sizing, cost and lead-time. Tube shapes include round, rectangular, square and others.
Tube drawing is very similar to bar drawing, except the beginning stock is a tube. It is used to decrease the diameter, improve surface finish and improve dimensional accuracy. A mandrel may or may not be used depending on the specific process used. The diameter and wall thickness of tubes that have been produced by extrusion or other processes can be reduced by tube drawing process. The process of tube drawing shown below is similar to wire or rod drawing except that it usually requires a mandrel of the requisite diameter to form the internal hole.
In such rapidly changing conditions, Judson Smith has introduced automation throughout the manufacturing floor to maximize production line efficiency. Our automation solutions help achieve increased production, in less time and with less waste.
Judson Smith has the capability to create custom machinery to automate the fabrication process, resulting in efficient and precise production
Smart solutions allow Judson Smith and our customers to enjoy greater business profitability.
Every ATW part is USA made, in a lean manufacturing environment, exactly to spec, no compromise in raw materials or quality systems. This means fewer barriers like time zone challenges and logistics issues for customers in the US, and reliable quality at globally competitive prices for customers around the world.
