Bakelite is an early plastic or resin made from synthetic materials. It was developed in the early 1900's and used to make items such as jewelry, billiard balls, toys and game pieces, radios, flatware sets, and many other products produced from the early to Mid 20th century. In photographic equipment, the most common items produced in Bakelite were cameras, light meters, lens caps and cases, developing tanks, and projectors.

The manufacturing process was labor intensive and the material was formed from an elimination reaction of phenol with formaldehyde, usually with a wood flour filler. It is still being produced occasionally for industrial uses, but no longer for consumer merchandise due to the labor and cost involved This makes Bakelite fall into the "retro" or "vintage" material category, and is often classified as a rare and more valuable plastic than modern plastics. Because there are so many different types of plastic, and some are very similar to Bakelite, it is often questionable as to whether an item was truly made of Bakelite or not. When it comes to vintage cameras, being made of Bakelite typically isn't a huge concern as it is with vintage jewelry, but the retro aspect still appeals Some cameras were only made out of Bakelite, and in these cases, there are also a few manual tests you can perform to determine if the plastic is indeed Bakelite.

Appearance and sound tests: Bakelite is a heavy, denser material than most plastics. It typically feels thicker and has a smooth finish. The finishing methods used to produce Bakelite removed any seams in the material so true Bakelite shouldn't have edges that visibly come The sound of two pieces of Bakelite clanking together typical produces a lower-pitched. The sound of two pieces of Bakelite clanking together typically produces a lower-pitched "clunky" sound. The sound is a little more subjective though, and shouldn't be sole relied upon as a testing method.
Parts are cut out of metal by sawing, shearing or chiseling either by hand or more commonly used with the aid of a specialized machine in a fabrication shop. If a sheet metal part is designed to function with two pieces joined together, the pieces are joined by Welding, the use of adhesives, rivets or threaded fasteners.
The parts of the parts being manufactured, engineers will determine which methods are used to ensure that the part will be as durable as possible. These parts are manufactured with essential precision to make them interchangeable, so that repairs and replacements can easily be made To whatever piece of equipment or structure the new parts are being used for.
Sheet Metal Parts offer the advantage of being both lightweight and durable. They are flexible enough that they can be pressed and bent into shape by hydraulic and brake presses during the manufacturing process, but strong enough that they will not break during use unless an unusually high Level of force is applied to them. Sheet metal parts are utilized in the many common consumer goods such as computers, cars, cabinets and air ventilation systems.
Typically, vendors approach a sheet metal fabrication shop with an explanation of the parts that they need to have manufactured for their product. Engineers from either the vendor of the fabrication company will then design a solution that meets the needs of the project. Are then put into use at the sheet metal fabrication site as a process is put in place to effectively create the parts.
Along the way, quality control processes maintain a high standard so that all parts are being produced with identical specifications and quality that meets or exceeds the level expected by the vendor. These parts are put to use for a variety of important applications, so it is Critical that no corners are cut during the manufacturing process.
We are surrounded by objects, most of which, some way or the other have a polymer associated with them. The ease of moulding polymers into different shapes and their relatively low cost of production has been The main reason for their universal usage. As such, Bakelite is one of the commercial manufactured polymers that we witness in our daily lives.
Bakelite is the commercial name for the polymer obtained by the polymerization of phenol and formaldehyde. These are one of the oldest polymers that were synthesized by man. Phenol is made to react with formaldehyde. The condensation reaction of the two reactants in a controlled acidic or Basic medium results in the formation of ortho and para hydroxymethyl phenols and their derivatives.
When the phenol is taken in excess and the reaction medium is made acidic, the product of the condensation reaction obtained is acidic. Whereas, when the quantity of formaldehyde taken is is acidic. Basic medium, the condensation product is known as resol.
Bakelite is obtained when novolac is allowed to undergo cross-linking in the presence of a cross-linking agent. In general, phenol taken in middle acts as the cross-linking agent. Cross-linked product of phenol and formaldehyde have the following structure.
Cross-linked product of phenol and formaldehyde
Uses of Bakelite
Now coming to the uses of Bakelite, since this element has a low electrical conductivity and high heat resistance it can be used in manufacturing electrical switches and machine parts of electrical systems. It is a thermosetting polymer and Bakelite has high strength meaning it basically retains its Form even after extensive moulding. Phenolic resins are also extensively used as adhesives and binding agents. They are further used for protective purposes as well as in coating industry.
Further, Bakelite has been used for making the handles of variety of utensils. It is one of the most common and important polymers that are used to make different parts of many objects.

What is Precision Metal Stamping?
Various metal stamping is an industrial process that uses machinery fitted with dies to transform flat sheet metal in either blank or coil form into different custom shapes. Other stamping, these metal presses can also perform a wide range of processes such as punching, tooling, notching , bending, embossing, flanging, coining, and much more.
It can be executed as a single-stage operation—where each stroke of the metal press produces the desired shape on the sheet metal— or in a series of stages.
The improving of the metal parts in various industries—from medical to automotive to aerospace — has pushed precision metal stamping to the forefront of manufacturing today. This is because it offers a high degree of design flexibility for defining and implementing minute features with tight tolerances And unique configurations.
In all, this makes precision metal stamping an ideal solution for the high-volume production of complex products, thanks to Its flexibility, speed and cost-effectiveness.
Advantages of Precision Metal Stamping
Precision stamping comes into its own when handling the production of precise metal parts. Once the equipment and dies are set, the process can run in a highly automated manner. This translates into 2 distinct advantages:
    Cost efficiency in production: Labor costs drop as production levels increase, making precision metal stamping a good choice for high-volume production of complex parts
    Consistent quality and accuracy: Precision metal stamping enables the production of very precise parts to the high degree of accuracy required in many industries today


A sheet metal part starts out as a flat piece of metal with a consistent thickness.
For manufacturing purposes, details like bend radii and relief sizes are usually the same throughout the part. You enter the values ??for these details, and then the software applies them as you design. For example, when you create a flange the bend is added automatically .
It is necessary to convert the folded model to a flat pattern for manufacturing purposes. Then you can switch between the folded view of the model and the flattened view by double-clicking the Folded Model or Flat pattern browser node.
    The mass and volume for Sheet Metal Parts are most accurately obtained from the flat pattern. The moment of inertia must be calculated from the final folded shape.
    You can use top down design methods to create multiple sheets metal bodies in a single part file. The Create Flat Pattern command is not available for multi-body parts. You must use the Make Components or Make Part commands to create derived parts that can be Flattened.
You can add features to the flat pattern for clean-up purposes. These operations are typically performed to support shop-specific manufacturing practices. Features added to the flat pattern using the commands on the Flat Pattern tab do not display when you view the model in The folded state.
Flat patterns rich with manufacturing information can be created and documented on drawings containing tables of holes, punches, and bends. You can export flat patterns to industry standard formats for CNC manufacturing.
When you use sheet metal parts in assembly models (not available in Inventor LT), sheet metal fasteners are available through the Bolted Connection Component Generator, or through Content Center.
Ways to Create Sheet Metal Parts
You can create sheet metal parts in several ways.
    Create a sheet metal part using the sheet metal template. The template uses your settings for material thickness, bend radius, and corner relief. You use sketch commands to create a profile for a base face or an initial contour flange. Then you exit the sketch And create your sheet metal feature, and add any additional sheet metal features required to complete your part.
    Create a regular part with a uniform thickness, and then convert it to a sheet metal part. Specifying a part as sheet metal displays the Sheet Metal tab, and adds sheet metal-specific parameters to the parameters list.
    Conversely, you can convert sheet metal part to a standard part. Doing so closes the sheet metal tab, and restores the standard part modeling commands and environment. Conversion of a sheet metal part to a standard part automatically deletes the sheet metal flat pattern. Time you delete a flat pattern in a sheet metal part, you also delete all flat pattern views in associated drawings.
    Note: When using this technique, ensure that the modeled sheet thickness agrees with the material thickness parameter setting. After converting a part to sheet metal, we recommend that you replace any dimension and parameter values ??that control the sheet metal thickness with the Thickness parameter. For example, in an extruded feature use Thickness as the extrusion value with the Distance extent method. The Thickness parameter updates the part thickness when you change the Sheet Metal Rule, or when you override the Thickness manually in the Sheet Metal Defaults dialog box.
    To create a sheet metal part to fit a specific set of conditions, construct a series of surfaces, stitch them together later, and then thicken them.

CNC machines are electro-mechanical devices that manipulate machine shop tools using computer programming inputs. Did you know? The name "CNC" actually stands for Computer Numerical Control and it represents one of two common methods (3D printing technology like SLA, SLS/SLM , and FDM being the other) to generate prototypes from a digital software file.
How it Works: Machining in general is a way to transform a stock piece of material such as a block of plastic and arrive at a finished product (typically a prototype part) by means of a controlled material removal process. Similar to the other prototype development Technology, FDM (3D printing), CNC relies on digital instructions from a Computer Aided Manufacturing (CAM) or Computer Aided Design (CAD) file like Solidworks 3D. The CNC machine interprets the design as instructions for cutting prototype parts. The ability to program Computer devices to control machine tools rapid advances shop productivity by automating the highly technical and labor intensive processes. Automated cuts improve both the speed and the accuracy with which prototype parts can be created - especially when the material is critical (such as is the case with Polypropylene - read more about polypropylene).
Oftentimes machining processes require the use of multiple tools to make the desired cuts (eg different sized drill bits). CNC machines commonly combine tools into common units or cells from which the machine can draw. Basic machines move in one or two axes while advanced machines Move laterally in the x, y axis, longitudinally in the z axis, and oftentimes rotationally about one or more axes. Multi axis machines are capable of flipping China Mechanical Parts over automatically, allowing you to remove material that was previously "underneath." This eliminates the Need for workers to flip the prototype stock material and allow you to cut all sides without the need for manual intervention. Fully automated cuts are generally more accurate than what is possible with manual inputs. That said, other finishing work like etching is better accomplished by Hand as well as simple cuts that would require extensive design work to program the machine for automation.

Processing requirements:
1. Size accuracy
The journal is the main component of the shaft part, which affects the shaft's rotation accuracy and working condition. The diameter accuracy of the journal is usually IT6 to 9 according to the requirements of its use, and the precision journal can reach IT5.
2. Geometric accuracy
The geometric accuracy of the journal (roundness, cylindricity) should generally be limited to the diameter tolerance point. For geometrical accuracy requirements, the tolerances allowed are specified on the part drawing.
3. Position accuracy
Refers to the coaxiality of the mating journal of the assembly transmission member with respect to the bearing journal of the assembled bearing, which is represented by the radial rounding of the supporting journal to the supporting journal; according to the requirements of use, the specified high-precision shaft is 0.001~ 0.005mm, and the general accuracy axis is 0.01 to 0.03mm. In addition, the coaxiality of the inner cylindrical surface and the perpendicularity of the axially positioned end surface and the axial line are also required.
4. Surface roughness
Depending on the working part of the part, there may be different surface roughness values. As the machine speed increases and the precision increases, the surface roughness value requirements of the shaft China Mechanical Parts become smaller and smaller.
5. When the bearing surface is different, it is not allowed to use
When the surface of the alloy bearing lining is yellow, it is not allowed to be used. The nuclear separation phenomenon is not allowed within the specified contact angle. The area of ??the core outside the contact angle shall not be greater than 10% of the total area of ??the non-contact area. The reference end face of the gear (worm gear) The shoulders (or the end faces of the positioning sleeves) should be fitted together and inspected with a 0.05 mm feeler gauge. The verticality requirement of the gear reference end face and the axis should be ensured.
6. Contact surface
After the outer ring of the bearing is assembled, it should be evenly contacted with the end face of the bearing end of the positioning end. After the rolling bearing is installed, the hand should be rotated flexibly and smoothly. The joint surface of the upper and lower bearing bushes should be closely attached. Check with a 0.05mm feeler gauge; fix with a positioning pin. When the bearing bush is used, the hinge and the pin should be drilled while ensuring that the opening and closing faces of the mouth and the end face are flush with the end of the relevant bearing hole. Do not loosen after the pin is inserted.
