Tahara has over 80 patents since we started making
Blow Molding Machine. Below 2 technologies are one of
our innovative invetions to improve fully electric mechanism.

The Prevention Mechanism of theMold Parting Line

Original point for absorption of deﬂection

By installing the synchronization
mechanism on the front platen and theParting Line
Servo motorDeﬂection

rear platen, it keeps the parting line
discrepancy below 50 μm.

DOUBLE STATION TYPE

While it dramatically increases the neckpart's ﬁnishing precision, it extends thelife time of calibration tools.

Mechanism

The Equalization Mechanism for theCalibration Force
Even each blow pin's height gets misaligned by up to 2 mm from each other,it automatically adjusts the diﬀerence of the calibration force by theautomatic correction mechanism.
Without spending time on theheight adjustment of blow pins, itenables to automatically adjust
the calibration force on eachblow pin to be equal.

Advantage of Co-Extrusion molding
The main advantage of extrusion blow molding is to produce Co-Extrusion
products. In order to keep the quality of product, Tahara's Co-Extrusion
technologies are used in many bottles such as food products, bevarage

We are making all of units by Tahara's original
design, which is including Co-Extrusion head,
Parison Controller, and Extruder.

products, and seasoning products.

Using recycle materials /Saving master batch

Barrier function

Making shinyon the outer layer

It is not usual for among overseas competitors to design each unit internally.
For example, some of the competitors purchase especially Co-Extrusion head that is
technologically diﬃcult and put on their machines and sell then to the clients.

the environment

In-mold Label(IML) Bottle

Small
PET Bottle

Multi-layer SmallPlastic Fuel Tank

On the outside appearance,
the bottle is produced byusing high gloss resin such as
PET-G or EVOH for the outerlayers. By beautifying theappearance, it can appeal
luxuriousness and alsoenhance the products'
added-values.

The label is inserted into theinside of molds; thecontainers are formed byblowing, also pasting label on
its surface. Because bottle
and label are rigidly glued,
the label does not peel oﬀ.

This is a PET bottle which ismade by extrusion blowmolding. It is suited for small
production which is diﬃcult
to produce by other molding
methods and for productswith the large blow ratio.

6 layer small plastic fueltanks are used for electric
generator, lawnmower, etc.
It prevents volatilization ofgasoline, and also reduces
products weights compared tometal tanks.

EVOH is used as barrier layer
for preventing oxidation ofcontents, which leads tolonger shelf life.
TAHARAʼ s multilayer headcan reduce the resin cost by
making extremely thin layersof barrier and adhesive
layers.

This is an industrial container
which has excellent chemical
resistance and strong
durability.
TAHARAʼ s machine canproduce various sizes ofcontainer up to 30 litters.

The bottles have stripe
