Woodcraft and bamboo craft can be enhanced using a variety of methods and techniques.
These include:
Woodturning is a process of using a lathe to make various forms and shapes of
wood.
Hand carving is considered a woodcraft in which a sharp object is used to create
designs on the wood. Various textures and surfaces can be created using this
technique. Tools such as chip carving knife, gouges, and chisels are used.
Pyrography is considered an art using a fire or heat to decorate wood or leather.
Flocking technique lines the interior of drawers and boxers with a soft velvety
finish.
Inlaying combines several techniques that involve inserting decorative pieces in to
a base object to incorporate new designs on the original product.
Gilding is considered as a decorative technique in which powder is applied on wood
or other materials to give a thin coating of gold. Methods of this technique include
gluing, chemical gilding, and electroplating.
Staining is used to color wood to give an illusion of texture. This may come in two
varieties. First, pigment-based stain will color large pores of the wood, while dyebased stain color small pores of the wood.
Painting is considered the simplest way of decorating wood since there is a variety
of colors that you can choose from. One may also add a lacquer finish to make it
shinier and glossier.
Electroplating
Chemicals and electricity create a metallic coating on the surface of individual
pieces. This process, known as electroplating, places a layer of nickel, chrome, zinc
or cadmium on the metal. Though this process does not smooth out errors in the
metal’s surface, the coatings have advantages. Cadmium and zinc reduce rusting
while chrome and nickel make the product more durable.
Powder Coating
Unlike electroplating that cannot do anything about surface defects, some powder
coatings can smooth these out. Powder coatings put a layer of durable melted
plastic powder onto the metal. Finishes can be glossy, textured, or matte. Textured
surfaces are best if surface defects exist. Glossy and matte finishes don’t do as good
a job at hiding surface defects. This method is also not ideal if you have sharp edges
that need to be smoothed out.
Hot Blackening
Like powder coating and electroplating, hot blackening coats the metal. This
process uses a heated process to make the surface highly durable. The result has a
black color, unlike other lighter-colored coatings. If color is more important than
durability, don’t use hot blackening. Since it’s used to enhance abrasion resistance,
hot blackening is best with harder metals. This coating is also ideal for heavy-use
items, such as firearm components, hand tools, and auto parts.
Vibratory Finishing
Vibratory finishing is often used for large-scale projects. Though the equipment
required is expensive, it operates faster than tumble finishing, according to
Finishing Systems. If speed is of the essence for finishing numerous metal pieces,
vibratory finishing is best. Though hand polishing works for individual pieces, you
cannot get the same polishing effects from hand work as you can with a vibratory
machine. This is an ideal method if you have surface defects you need to remove.
Grinding
Grinding produces a wide range of finishes, but it requires skilled workers to use
the grinders on individual pieces. This process takes time and multiple steps to
achieve the smoothest finish. It’s best for mold-making where molds require
precise, perfect smoothness inside. According to Mold Making Technology, good
grinding requires three major steps – grinding, hand stoning and diamond
polishing. With each step, the finish becomes smoother and finer.
Sand-Blasting
Sand-blasting works best for large, flat surfaces that require a matte finish. This
process requires special eye and respiratory protection for workers who use
blasters that force tiny particles at the metal. Since it uses sand to shape the metal,
this process is better for softer metals, which are more easily formed by the sand.
As expected, skip sand-blasting for very small, fragile or highly detailed pieces.
Buff Polishing
Buff polishing does an excellent job with creating a smooth, non-textured surface.
It uses a cloth on a polishing machine to give a rounded finish. While the finish can’t
be topped with a buff polisher, it cannot be used if you have intricately designed
metal pieces with small crevices the cloth cannot reach. It’s also not ideal for very
fragile pieces.
Brushing Metal
Brushing metal gives it a uniform finish, thanks to the design of the machine. Unlike
grinders, which require precise movements over the metal, brushing only needs
the piece to be held against a belt. The brushing merges the best of buffing and
grinding to smooth out defects and create a pristine surface. Special brushes may
be used to create specific grains on the final product.

Five Steps in Mass Production
Step #1: Developing the Right Concept
Having a product concept that somehow transforms the current
market you’re targeting is definitely a bonus, but a simple, well designed
concept works well too. Many of our clients come to us with ideas that
would make their jobs (and lives) easier. We know that all of you have
brilliant ideas, and we can’t wait to hear all about them!
Step #2: Turning Concept into 3D CAD Model
After you have fully developed your genius idea, you’ll need to
create a 3D CAD file of the design. There are many software programs
out there to aid in your 3D CAD modeling. Choosing a CAD program to
design with will be largely dependent on what your concept requires.
Once your design is finalized, the next step is to submit it to Stratasys
Direct Manufacturing for prototyping.
Step #3: Prototyping
You can’t expect to successfully develop a concept in CAD—no
matter how wonderful—and go straight into production. Renderings of
an idea that look great on paper or in the virtual realm have no true
bearing on the physical realm until they become physical. To ensure the
most success with your concept you’ll need prototyping, whether you
are prototyping for functionality, form and fit, to check design aesthetics,
or all of the above. Technologies frequently used for concept models and
design evaluations include 3D Color Prints, PolyJet 3D printing,
Stereolithography (SL), Laser Sintering (SL), Fused Deposition Modeling
(FDM), CNC machining and Quantum Cast Urethane Casting. With lead
times as little as 24 hours, additive manufacturing technologies are a
quick and effective way to assess and create the best designs for your
project at hand.
Step #4: Test Your Product on the Market
We’ve heard innumerable times from clients that our prototypes
or pre-production parts, brought directly to our client’s customers,
provided crucial feedback that dictated the way our client’s product
entered targeted markets. Methods such as additive manufacturing and
urethane casting for low volumes of production are ideal because the
price for tooling and injection molding may be unnecessarily costly with
specialized or custom one-off products. Urethane Casting give customers
the leisure to discover how strong market interest is and grow their
market base without heavy upfront investment. We provide solutions for
fast results with the option of low volume urethane casting productions.
One of our clients recently relied on Quantum Cast Urethane Casting to
create a short run of functional parts for testing. “After design
modifications and verification, we actually used the urethane casting
process for our initial product launch. We used the casting process far
beyond what we originally meant to use it for,” he said. Once his team
had completed testing on the Quantum Cast parts, they then took the
product to their targeted audience and displayed how smoothly it
performed. By providing our client with completely professionally
finished urethane casting—which simulate injection molded plastics,
proving to be quite durable—they were able to receive not only positive
market feedback, but were also able to launch their product’s initial
market phase.
Step #5: Mass Production
When moving into mass production, it’s important to remember
not only the volume of parts you want, but the finishing and assembly of
your entire product. This is most viable for clients who have assessed
their targeted market and assessed buyer response, and can therefore
confidently invest in tooling and injection molding for the volume of
parts they want. We can provide customer projects customized solutions
with our hard tooling and injection molding services. Our U.S. based
project engineers ensured a smooth production process, while the actual
manufacturing was occurring in China to help keep costs competitive. For
many of our customers, producing parts with our urethane casting
processes to simulate injection molded parts provides them with the
answers they need to make the final leap into mass production. It helps
to lower risks and give confidence in the success of the product.
