ALL YOU NEED TO KNOW ABOUT PRECISION INVESTMENT CASTING
</h1>
<p>
Precision Investment Casting, also referred to as lost wax casting, is a process in
which metals are casted into different shapes using wax and ceramics to act as the mould
for the casting. This is one of the oldest known techniques for metal casting and has
stood the test of time over centuries.
</p>
<p>
It finds usage in various industries like firearms industry, energy industry, gas and
oil and even food industry. While many debate upon the strength and durability of this
form of casting, doubting mainly that this method might provide weaker metal shapes as
compared to forging or metal fabrication, these doubts have been laid to rest since
aerospace, defence and medical fields have trusted equipment that are made from <a

<h2>
WHAT IS THE PROCESS FOR PRECISION INVESTMENT CASTING?
</h2>
<p>
As mentioned earlier, the process for Precision Investment Casting requires wax and
ceramics to be the mould for the main metal. This is done in a very simple yet precise way
(hence the name) and the steps are:
</p>
<p>
? Pattern Formation –Manufacturing of the wax pattern is the very first step involved
in investment casting. Here it should be mentioned that wax is preferred over plastic,
because wax melts easily and can be reused for another casting which is again a beneficial
point from costing aspect. Special aluminium moulds are made to cast the pattern and this
requires some trial and error, because factors like shrinking of the wax, the ceramic or
even the metal should be incorporated.

The hard facts on marine hardware and components
</h1>
<p>
While it may seem like a proportionally small detail for an overall marine fabrication
project, finding the best hardware can significantly prolong the lifespan of an end
product and tailor it to a specific customer’s needs. The technology for marine hardware
is always changing, and it can be hard to keep up with the new products in the gap between
trade shows. We caught up with a few of the nation’s most successful manufacturers and
distributors to find out what’s hot this summer, and what fabricators can do to stay in
the loop on the latest hardware products available.
</p>
<h4>
The development cycle
</h4>
<p>
Manufacturers insist that input from marine fabricators, regardless of the size of the
shop they run, is key to developing new and more technologically advanced hardware.
However, the process for developing a new item can take upwards of three years.
</p>
<h4>
What’s hot
</h4>
<p>
Because of the lengthy testing period, some of the <a
href="http://www.disoncasting.com/marine-hardware/" target="_self">marine hardware</a>
just entering the market now are products that have been around for a year or more—but <a
href="http://www.disoncasting.com/" target="_self">manufacturers</a> say that should help
fabricators feel confident that these “hot” new products are road-tested and trade-show
approved.
</p>
<p>
Alan Butcher of Intermold says his company is seeing rising popularity in two of its
more versatile products: a new Lever Lock Joiner that securely fastens the telescoping
support poles of an awning without having to use screws, and a universal deck hinge that
can adapt to a wide variety of boat decks.
</p>
<p>
“There’s a whole bunch of deck hinge combinations out there, which is one reason we
made the universal deck hinge,” Butcher says. “It swivels, and it fits a lot of
different deck combinations, so the customer doesn’t have to have the exact angle. In the
past they’ve had to slip wedges under them to change the angle of a hinge, because every
deck has a little bit different camber to it. So we added a universal hinge that will
adjust to whatever deck you put it on, and many customers have found that to be to their
advantage.”
</p>
<p>
Tom Koster also emphasizes the importance of being able to offer versatile hardware.
He says that one of his most popular new products is a ball and socket fitting, which can
help a fabricator to fit a frame around the curved edges and adapt to new kinds of boats.
</p>
<p>
“Boats used to be more or less a lot of right angles, or straight angles, but now
boats are manufactured with compound curves,” Koster says. “So when you put a frame
down, it isn’t a straight line, because the boat itself is curved, the fittings have to
be flexible, and allow movement within the hinge itself.”
</p>
<p>
The newest product we found has only been in development for 18 months, and is just
being placed on the market for the first time: YKK’s new adhesive snap fastener, called
the Snad. Rod Helwig of YKK says that the Snad was developed as a response to fabricators
’ concerns about traditional snap applications.

What are metal products?
</h1>
<p>
The steel industry, the business of processing iron ore into steel, which in its
simplest form is an iron-carbon alloy, and in some cases, turning that metal into
partially finished products or recycling scrap metal into steel. The steel industry grew
out of the need for more durable and more easily produced metals. Technological advances
in steelmaking during the last half of the 19th cent. played a key role in creating modern
economies dependent on rails, automobiles, girders, bridges, and a variety of other steel
products.
