PET blow mould
WASHUN supplies varieties of PET blow moulds, which has covered the whole fields of mineral water, soft drink, and juice as well as in other food and non-food utilization. It permits our customer to produce high quality PET bottle with the most economical investment, the shortest production startup time and the lowest maintenance cost. The latest technology with our experienced design staff is our key to keeping ahead in the PET blow mould field, for example, our design department is equipped with CAD, 2D & 3D software running on the latest platform and those systems are used to design container and the complex surface plastic product required to create tooling for today’s complex PET bottle shapes.

Overview
Bottle design
WASHUNdesign department is equipped with
advanced 2D & 3D modeling software.
Those systems are used to design PET bottle
as well as the complex surface generation
for today’s plastic industry. Together with
many years’ experience and advanced design
tools,WASHUNcan turn your bottle design idea
into reality and make sure it meets your
requirement.
Material for mould
building
45# carbon steel is usually considered as
standard material to build stretch blow
mould because it is very easy to machining
after forging treatment. However, as
customer’s requirement, we also use S136
stainless steel to build mould, The S136 do
not need the chrome treatment. The 6061 and
7075 aluminum is also available, due to the
property of the aluminum, the blow mould has
the great heat transmission and lightweight.
Mould building
machining
For different bottle shape,WASHUNadopts
Lathe, EDM and CNC machining center on mould
building correspondingly. Perfect shaping,
final volume matching, slight parting-line
on the final bottle and proper cooling
channels design with leakage proof are main
features ofWASHUNstretch blow mould.
Coating after
machining
After final test on the mould, we will make
the mould surface chrome plated to prevent
the mould from rusting and increase mould
surface hardness for long time use, the
different coatings also are available at
Ywashun machinery.
Quality control and
inspection
At the beginning of the bottle design, we
pay much attention to bottle shape and
volume. During building we select the most
suitable machining techniques and tools to
get a nice mould body. After assembly, we
will test the mould several times to check
the bottle actual volume, parting line and
final shape. If needed, the adjustments will
be done on the mould so that it meets
customer’ requirement completely.
