2. SMA connector - Wikipedia

   en.wikipedia.org/wiki/SMA_connector

   The interface dimensions for SMA connectors are listed in MIL-STD-348. [5] The SMA connector employs a 1 ⁄ 4 inch diameter, 36-thread-per-inch threaded barrel. The male is equipped with a hex nut measuring 5 ⁄ 16 inch (0.3125 inch / 7.9 mm) across opposite flats, thus taking the same wrench as a #6 SAE hex nut.

3. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   extrusion into tubes, rods and other profiles including multiwall; extrusion with cylinders into sheets (0.5–20 mm (0.020–0.787 in)) and films (below 1 mm (0.039 in)), which can be used directly or manufactured into other shapes using thermoforming or secondary fabrication techniques, such as bending, drilling, or routing. Due to its ...

4. Filler (materials) - Wikipedia

   en.wikipedia.org/wiki/Filler_(materials)

   Polymer Foam Beads can have a bulk density as low as 0.011 g/cc and range in size from 45 microns to over 8 mm. Common drawbacks to using Polymer Foam Beads in formulated systems include static, temperature, and chemical resistance limitations and difficulty achieving a homogenous blend within a formulated system due to their extremely low bulk ...

5. Extrusion - Wikipedia

   en.wikipedia.org/wiki/Extrusion

   Mixing elements or convey elements are used in various formations. Extrusion is common in the application of adding colorant to molten plastic thus creating specific custom color. Extrusion is also a process used in fused filament deposition 3D printers, whereby the extruder is often composed of a geared motor pushing plastic filament through a ...

6. BSA Bantam - Wikipedia

   en.wikipedia.org/wiki/BSA_Bantam

   BSA introduced the D3 Major in 1954. It was the first development from the original Bantam. BSA increased the engine cylinder bore from 52 mm to 58 mm, which gives the D3 a displacement of 148cc, and increased its power from 4.5 to 5.3 bhp. The air-cooling fins were also enlarged, which changed the external appearance of the engine.

7. Spinning (polymers) - Wikipedia

   en.wikipedia.org/wiki/Spinning_(polymers)

   Wet spinning is the oldest of the five processes. The polymer is dissolved in a spinning solvent where it is extruded out through a spinneret submerged in a coagulation bath composed of nonsolvents. The coagulation bath causes the polymer to precipitate in fiber form. Acrylic, rayon, aramid, modacrylic, and spandex are produced via this process ...

8. Rule based analysis of extrusion process - Wikipedia

   en.wikipedia.org/wiki/Rule_based_analysis_of...

   In direct extrusion the billet is pushed through the die with ram pressure, whereas in indirect extrusion a die moves relative to the container. Rule based analysis of extrusion process would help to determine a set of rules essential for consideration while designing a product, or even during cost estimation of a product.

9. Plastic welding - Wikipedia

   en.wikipedia.org/wiki/Plastic_welding

   With speed welding, the plastic welder, similar to a soldering iron in appearance and wattage, is fitted with a feed tube for the plastic weld rod. The speed tip heats the rod and the substrate, while at the same time it presses the molten weld rod into position. A bead of softened plastic is laid into the joint, and the parts and weld rod fuse.
