Vulcanizing Frame

The DOGENDORF Vulcanizing Frames have excellent surface characteristics,
made of milled aluminium and provide best stability. 

The Vulcanizing Frames can be ordered with Codifying Field of the
DOGENDORF Codifying System for the following rubber mould sizes*:

  • 65 x 50**
  • 75 x 60 (frame 60 x 120 x 118 mm)
  • 85 x 70 (frame 60 x 130 x 118 mm)
  • 110 x 90 (frame 79 x 135 x 157 mm)
  • 120 x 100 (frame 79 x 145 x 158 mm) und
  • 230 x 150 mm (frame 79 x 295 x 198 mm)

The anodized Vulcanizing Frames contain a DOGENDORF Codifying Field, too,
but on top of that they are equipped with ball-grips and an air connection to provide
a perfect rubber mould press-out directly after the vulcanization process with the
QUATTRO PARALLEL VP 200 (or VP 250, VP 160) for the easier operability.
They are available in the following rubber mould sizes*:

  • 65 x 50**
  • 75 x 60 (frame 60 x 120 x 118 mm)
  • 85 x 70 (frame 60 x 130 x 118 mm)
  • 110 x 90 (frame 79 x 135 x 157 mm)
  • 120 x 100 (frame 79 x 145 x 158 mm)

 

* Other sizes on request
**  The Codifying Field on the Insertion Plate with the size 65 x 50 mm uses
not the full range of parameters, as it is necessary
to ensure the full functionality despite its small size

Acrylic Frame

The DOGENDORF Acrylic Frames makes the production of high-quality,
precise and durable silicon moulds possible. On one side of the Acrylic Frame
there is the DOGENDORF Codifying Field so that the future silicon moulds
can be used with a set of Codifying Field parameters. 

The production of silicon moulds with the DOGENDORF Codifying Field:

To enable the easy placing of the model the upper tray can be removed
at the beginning.

On the bottom of the Acrylic Frame there are three holes alongside each
other which are meant to be used for the positioning of the cone. Because the
Acrylic Frame allows three different diameters of silicon moulds the position
of the cone is decided regarding the character of the model.
It is set on the cone and the side panel is assembled.

Ideally the liquid silicon is filled in the Acrylic Frame through a mixing unit.

The upper tray is placed on top the Acrylic Frame, by which the future
silicoe mould gets it exact size and shape, and that the surplus material
can escape through a leave-out in the upper tray.
Depending on the silicone curing method the silicon mould can be
removed and cut open after the dedicated time.

The Acrylic Frames are available in the following inner dimensions:

  • 65 x 50
  • 75 x 60
  • 85 x 70
  • 110 x 90 and
  • 120 x 100 mm

* Silicon can be ordered on request

Rubber Mould COMPACT

For more than 35 years we offer our manufactured raw rubber moulds in highest quality.

Then as now these classic DOGENDORF products provide both small companies
as well as large-scale productions with great wax pieces with most various characters.

From the Raw Rubber Mould COMPACT to Your Rubber Mould – Process of Formation and Purpose

Depending on the model’s volume and form a specific amount of rubber is cut
out of the raw rubber mould. Then the original master model is placed between
both halfs of the COMPACT rubber mould. Thanks to the condition and quality of the COMPACT there is no risk of bursting or moving oft he model. The raw rubber mould is placed in a vulcanizing frame, heated to about 150 °C / 302 °F, where the raw rubber liquefies in the vulcanizing frame. The high pressure and temperature lead again to a solidification of the material. Thereby the transformation process from raw rubber mould to rubber mould is completed. 

The technique of removing of the original model is decided upon its complexity:

Tearing Technique (used with easy models)

Both contact areas are treated with a mould release agent, e.g. a Silicone Spray whereby they won’t combine during vulcanizing. As a result, both, the tearing apart of both rubber parts and the removing of the master model is made possible without a reduction in functionality of the rubber mould.

Cutting Technique (used with complex models)

A model-specific separation line is drawn on the raw rubber mould before vulcanizing, which is cut open by a scalpel after cooling down. 

Advantages

  • The Two-Piece Raw Rubber Mould COMPACT guarantees highest quality in production of
    most precise wax pieces of most various types of rubber moulds
  • Great durability of the rubber mould vs. silicon mould
  • Easy and clear storage of different models, different aligned sizes of raw rubber moulds

Available Sizes*

  • 65 x 50
  • 75 x 60
  • 85 x 70
  • 110 x 90 and
  • 120 x 100 mm

All sizes available in 

  • 4 layers and
  • 6 layers

and optional in

  • CASTALDO GOLD LABEL (soft and flexible characteristics) or
  • CASTALDO WHITE LABEL (firm and stabil characteristics)

* Other sizes on request

QUATTRO HYDRAULIC 200/160

The hydraulic pressure generation makes a very high pressure possible.

The upper heating panel, led via four pillars, which remains stable during vulcanizing,
ensrues a parralel and highly condensed rubber mould (not spongy).

The rubber mould remains elastic permanently, since through vulcanizing
with the QUATTRO HYDRAULIC 200/160 a significantly higher density is obtained,
as reachable with a pneumatic vulcanizing press.

  • Each heating panel has its separate regulation of temperature
  • Dimensions of heating panels: 200 x 160 mm 

Technical Data

Voltage: 230 V
Power: 1000 W
Frequency: 50/60 Hz
Contact Pressure: 5 t
Dimensions (H x W x D): 510 x 330 x 230 mm
Weight: ca. 47 kg

QUATTRO PARALLEL VP 200

Our manual Vulcanizing Presses* QUATTRO PARALLEL VP 200 features
an upper heating panel that is moved downwards by an easily rotatable
handwheel via four gears and four threaded spindles. As a result
the upper heating panel is moved parallel and remains perfectly stable
while vulcanzing, which ensures

a compact (not spongy) and parallel aligned rubber mould.

The rubber mould remains elastic permanently because a significantly higher
density is reached during the vulcanizing process.

During the whole pot life – this is the duration, in which the rubber is
deformable (liquid) and has a very high coefficient of expansion –
it is from great importance to reach very high forces:
that on e.g. a 110 x 90 mm rubber mould the hydraulic pressure
rises from 200 bar up to 400 bar.

In a pneumatic vulcanizing press this high pressure entails that the
heating panel opens and the aforementioned density during
pot life is compensated, which leads to unwanted results.

Advantages of the QUATTRO PARALLEL VP 200

  • No more spongy rubber moulds and no more products of chance!
    Irrespective your vulcanizing frame lies centrally or laterally
    you will always obtain a 100% parallel, dense and stable rubber mould
  • To minimize the heat transmission on the vulcanizing press,
    every heating panel has two thermal shields: a 10 mm mineral fibreboard
    and a circulated bridge, respectively
  • The threaded spindles and gear wheels are made of high quality steel
  • Each heating panel has a separate regulation of temperature

Technical Specifications

Diameter of Heating Panel: 200 mm
Space between Heating Panels: 125 mm
Maximum vulcanizing mould size: 120 x 100 mm

Dimensions (H x W x D): 650 x 430 x 230 mm
Voltage: 230 V
Power: 1300 W
Frequency: 50/60 Hz
Weight: ca. 46 kg
