Magnesium
Zinc
Water-based release agent based on synthetic hydrocarbon oils

This product is wax-free

General purpose product
Isolat ZN 90 DZinc
Oil-based release agent for zinc, suitable even for the most difficult castings

Heat loss is considerably less compared to aqueous products
Isolat NAluminium
Magnesium
Die-oil for high-pressure Die-Casting in multiple-stage spray systems in conjunction with water based products

Better release on hot gates and cores, tool life is increased
Isolat UP 27Aluminium
Magnesium
Thin release oil with extreme release power

Primarily recommended as a coating for new dies

Product forms a permanent patina on the die-surface

It can either be applied on its own, or in conjunction with water-based release agents.
Graphitex 012Aluminium
Graphite coating for gravity and low-pressure Die-Casting

This product is comprised of a highly heat-resistant graphite matrix, which resists oxidation at elevated temperatures
Graphitex CR 34/01Brass
Graphite-based release agent for all copper metals
Minex Impra FA 6Aluminium
Thermo-insulating coating for gravity and low-pressure Die-Casting

It induces a durable coating and smooth casting surfaces are obtained

Best casting results are obtained if applied in conjunction with Graphitex 012

PLUNGER LUBRICANTS

PLUNGER LUBRICANTS

1. BEADS
80G-0.3-080G-1-195W-0.9-1

The FOCHEM INTERNATIONAL plunger beads are made from a hard synthetic wax with a low melting point. The globules are perfectly round and therefore free flowing, anti-static and dust-free. They are suitable for tropical conditions.

FOCHEM INTERNATIONAL’s beads effectively protect the shot sleeve against aluminium erosion and they can be used in very small amounts, ensuring casting porosity is minimised.

We strongly recommend using the FOCHEM INTERNATIONAL “Beads Dispenser 3D”.  This gives a reliable and precise application at all times and the amount of beads can be greatly reduced.

2. FOCHEM INTERNATIONAL DISPENSER 3D

dispenser-front           Dispenser2

The “Beads Dispenser 3D” is the first digital beads dosing machine ever offered to the Die-Casting industry, manufactured by the associate company TRIBO-CHEMIE GmbH in Germany.  It is equipped with a newly developed dosing technology, providing extremely accurate process assurance. Regarding the quantity of beads variations, very small amounts can be precisely dosed.

The digital display enables the machine operator to easily monitor the process. The amount of air, as well as the spray time can be modified digitally. The “Beads Dispenser 3D” can either be operated manually or it can be linked to the electronics of the die-casting machine. All positions and movements of the pneumatically operated dosing arm can be adjusted 3- dimensionally.

We assure that you will not have to deal with any problems relating to blockages of the dosing tubes or fluctuating dosing amounts. The entire operation of the “Beads Dispenser 3D” is reliable, precise and the work environment remains clean.
