Blow Mould Tool Design and Manufacturing Process for 1litre Pet BottleIOSR Journals
the concepts of Blow molding is a process used to produce hollow objects from thermoplastic. The
basic blow molding process has two fundamental phases. First, a parson (or a perform) of hot plastic resin in a
somewhat tubular shape is created. Second, compressed air is used to expand the hot perform and press it
against mould cavities. The pressure is held until the plastic cools. Blow molding process is used for which has
thin wall sections.In this thesis, blow mould design is to be done for a bottle having 0.5mm thickness. This
thickness cannot be filled in pressure injection molding. So blow molding is considered for pet bottle design.
The mould is prepared by first modeling the part, extracting core & cavity and generating CNC program. Blow
mould tool design is done in Pro/Engineer according to HASCO standards. A prototype of the pet bottle using
blow mould design is also included.

Design and Manufacturing of Pet Bottle DieIJMTST Journal
A bottle is a rigid container with a neck that is narrower than the body and a "mouth. Bottles are often made of glass, clay, plastic, aluminum or other impervious materials, and typically used to store liquids such as water, milk, soft drinks, ink, chemicals and etc. A device applied in the bottling line to seal the mouth of a bottle is termed an external bottle cap; the bottle has developed over millennia of use, with some of the earliest examples appearing in China, Phoenicia, Rome and Crete. Bottles are often recycled according to the SPI recycling code for the material. Some regions have a legally mandated deposit which is refunded after returning the bottle to the retailer. Blow molding process is pretty much comparable with injection molding but the only difference is that, in this case, heated liquid plastic vertically pours out of barrel-like pot into molten tubes. The vacuum part is created. Most bottles are formed with this type of molding. Hot plastic resin is combined with a pressurized gas to fill and press the mold cavity, forming a hollow part.

Centrifugal Iso-Finishing Technical article as seen in Products Finishing mag...Dave Davidson
This high-speed, high-intensity mass finishing
method can improve part performance. Centrifugal iso-finishing can be used not only for deburring and edge-contour, but also to
develop surface finish attributes that improve the performance,
surface integrity and service life of components.
A High-Speed, High-Energy Alternative
Centrifugal iso-finishing is a high-speed and high-intensity
mass finishing method in which abrasive or polishing materials are caused to interact with part edges and surfaces
with 10 times the surface pressure of low-energy finishing
methods. What this means, in practical terms, is that it is
possible to produce very refined surface finishes in abbreviated process cycle times. It also means that parts with
complex and detailed geometries can be deburred with a
minimum of manual intervention.

It's the Finish that Counts. Technical Magazine article reprint.Dave Davidson
A conventionally produced surface (turned, milled,
ground, EDM) is typically Gaussian in nature, that is,
the peak and valley distribution is pretty much equal
in height. This type of surface can be very unstable and
unpredictable when wear and load bearing are considered. The images in Figure 1 demonstrate this type of
surface.
There are many ways to produce plateaued surfaces.
They are varied in approach but all have the ability to
control the surface peak characteristics separately for
the valley characteristics. Methods that are used to improve surfaces for performance and increased service life include centrifugal barrel finishing, turbo-abrasive machining (aka Turbo-Finish) and isotropic micro-finishing with vibratory finishing equipment.

2. INJECTION MOLDING
FUNDAMENTALS
Reiff Injection Molding — Success from Adaptation...
Case History/Plant Tour – Spokane, Washington., Jan. 23, 2007
by Dave Davidson. Photos by Ray McDied
Tour Organized by Society of Manufacturing Engineers, Spokane, WA Chapter 248
Injection molding is
the most popular method
of making plastic molded
parts.
Jim and J. McCall own and operate Reiff Injection
Molding Co., a manufacturer of plastic injection molded parts originally established in 1979 in Walla Walla, WA. The company moved
to Spokane, WA in 1999 and recently moved from its University
Road operation to larger facilities located at 131 N. Pittsburg close to
the Altamont exit on I-90.
The company runs four different plastic injection molding machines, and manufactures parts for a variety of industries including
the medical, telecom, irrigation and recreation industries.
Injection Molding has
the advantage of quality
parts produced in high
production runs at low
cost.
In Injection Molding
normally small solid plastic pellets are put into a
hopper on the injection
molding machine. The
plastic travels through a
long cylinder known as a
barrell. The barrell has
an auger in it that is
known as a screw. While
the plastic pellets are
traveling through the
barrell they are heated
and melted.
At the appropriate
moment the molten plastic is rapidly "injected" at
high pressure into a precision closed mold. See
the graphic on our home
page.
The plastic then cools
and solidifies in the
mold. The mold then
opens and the plastic
part or parts are ejected
from the mold.
Plastic Injection Molding cell at Reiff Injection Molding
Inc., plant tour attendees watch as Jim and J. McCall explain operations of the four machines in the cell including: (1) BOY 25 Ton x 1
oz. (2) Toshiba 85 &on x 3.2 oz. (3) Toshiba 190 Ton x 10 oz. (4) Cincinnati- Milacron 300 Ton x 30 oz
Cycle times for producing
parts can typically be
from 40 to 60 seconds.
Plastic table ware can
run as fast as 4 seconds.
Challenges: Like many American manufacturers, Reiff has faced serious challenges due to the outsourcing of products overseas. The
company faced a severe test when one of its major customers, a subsidiary of a Fortune 500 firm decided it was going to start outsourcing product from India. This change was particularly unsettling as it
would mean not only loss of one of the company's largest customers,
but the loss of the company facilities as well, as the large customer
had been providing facilities for the plastic injection molding
Most molds are single
cavity (produces one part
each cycle). If the mold
has 200 cavities (makes
200 parts in one cycle)
and cycles in 4 seconds
then the production is
200 parts in 4 seconds or
3200 parts a minute.
If you notice the number on the back of plastic
table ware next time you
are at a fast food place,
that tells you which cavity the part came from.
The little round circles
are from the ejector
pins. Can you figure out
where the plastic was
injected into the cavity?
That is called the gate
and is normally at the
end of the handle.

TOSHIBA 190 Ton x 10 oz. injection molding machine to Jeff Dornerberg,
an associate professor in the Mechanical Engineering Dept. at Eastern
Washington University. The university located in Cheney, WA. was a recipient
of an SME Education Foundation grant ($220,000.00) used in the construction
of it’s new computer science facility.

The company has not only survived but has successfully expanded its business through utilizing its internal
strengths to provide exceptional customer service that
competitors find difficult to duplicate. As a family business, father Jim McCall has a strong process and operations background working with Whirlpool Corporation
in Michigan after receiving a master’s degree in engineering from the University of Michigan. Son, J.
McCall, has a strong plastic materials background with
a degree from Western Washington University. Together, they are in a position to not only offer manufacturing services but custom engineering development
and materials selection advice to customers who need
this kind of process development assistance to take
parts from prints in the design stage and turn them into
reality. They have locked in customer relationships not
only by being a manufacturing source for plastic
molded products, but by also being a design and engineering resource to customers who have new product in
the formative stage. They are especially adept at assisting customers in modifying or tweaking original designs in such a way to make actual production operations more practical, feasible and cost efficient.
As an example of this, Jim McCall, explained an especially challenging design and operational problem
the company had been faced with recently involving
“puffer nozzles”. This molded component is part of a
sophisticated quality assurance system used in the food
and produce industry. As items are passed down the
length of an inspection conveyor they are analyzed by
an optical/video system which can identify defective or
nonconforming items. Once an identification has been
made the system will remove the offending item from
the production stream by actuating the “puffer nozzle”
which then directs a “puff” or “blast” of high velocity
air at the defective piece as it comes off the conveyor,
segregating it from acceptable product. The “puffer
nozzle” is a challenging product for the plastic injection
molding process where products are typically designed
with a specific taper to promote ease of ejection from
the mold at the end of the injection cycle. On this part
the internal orifice had to be designed with a taper opposite to that which would be normal for ejection purposes in order to produce sufficient velocity in the air
puff used to remove the piece from the conveyor
stream.
