Fostermation, Inc. has been a leader in the manufacturing of Terminal Pins for tubular heating elements since 1971. Both upper and lower styles can be produced in a variety of configurations.
Upper pins are manufactured to standard Oakley configurations. Lower pins can be upset, headed, knurled or slotted.
Coil ends can be manufactured with a taper or radius form.
Materials used are C1008/1018 or C1215 CRS (either plain or with a pre-plated 1/2% or 2% nickel plate or a post electro-nickel plated finish), stainless steel and brass.
Threaded Pins are used when two pieces must be assembled and must support a load, typically as a fastener. The strength capabilities depend upon the thread dimensions and the mechanical properties of the fastener material.
The thread is formed when a die, a hardened piece of steel with the desired thread profile, is applied against a revolving work surface. As applied force is gradually increased, the thread profile is transferred to the work piece. The result is a stronger thread than the one that is ground or cut.
Most metals can be thread rolled, including steel, stainless, brass and aluminum. Fostermation, Inc. can assist you in the exact material grade, tensile selection and thread specification to maximize product performance for your particular application.
A Knurled Tooth is V-shaped and the depth of the tooth is less than the depth of a theoretical V-form. The tooth has a rounded root and crest. The relationship between the actual depth of tooth to the theoretical V varies with the pitch of the teeth. On finer pitches, the tooth is a smaller proportion of the theoretical V-depth then coarser pitches. Also, female diamond patterns have shallower tooth depth than male diamond patterns.
Knurled Pins are used in a variety of applications in the screw machine, fastener, plastics and automotive industries. Knurling is most commonly used for serrating surfaces where component parts must lock together in unit assemblies.
Knurling is the process by which material is displaced when a die with the opposite form is rolled across the work surface. The resulting form is a series of V-shaped impressions on the circumference of the piece whose overall configuration can either be a straight, diagonal or diamond pattern.
Most metals can be knurled, including steel, stainless, brass and aluminum. Fostermation, Inc. can assist you in the exact material grade, tensile selection and knurl form specification to maximize product performance for your particular application.
Fostermation, Inc. has recently added CNC-Swiss type capabilities to its impressive list of manufacturing processes with the addition of 5-axis CNC Swiss machines that contain live tooling. This gives us a full range of CNC swiss machining processes for the production of precision parts without expensive secondary operations. We are now able to manufacture complex parts with ultra high-speed flexibility.
Our CNC-Swiss machines can produce parts with diameters up to 20mm (3/4″) and lengths up to 155mm (8.00 in). Note: longer lengths are available with a special attachment. This latest technology utilizes multi-axis machines, equipped with live tooling, for milling, cross-drilling and back-working. It provides maximum flexibility for complete complex parts, eliminating costly secondary operations.
Cross drilling, center drilling, C-axis rotation, sub-spindle rotation, automated magazine bar feeds, deep drilling, tapping, threading, milling slotting and broaching can all be accomplished with ease. Typical turn tolerances can be held to +/- .0002”.
