Fochem International: Plunger Beads for High Pressure Die Casting

Reading time: min

It is our great pleasure to introduce our latest generation of beads as plunger lubricant. Our state-of-the-art manufacturing plant is now in operation. Based on 40 years of Research & Development, as well as feedback from our customers, we can claim that our products are today considered the most advanced on the international Die Casting market.

WHITE BEADS – PLUNGER LUBRICANT, containing white pigments

Our newest development, Isolat 95W, is a valuable asset in addition to our product portfolio. These “white beads” offer excellent lubricating properties due to a solid content of 20%, consisting of a unique mixture of micronised white lubrication pigments. Due to this high solid content, the quantity per shot can be reduced significantly, in comparison to white beads without solids. The congealing point of Isolat 95W is >95°C. The bulk density ranges from 0.55-0.7, depending on the fraction. To meet customers’ requirements, Isolat 95W is available in different sizes:


FOCHEM INTERNATIONAL offers a wide range of plunger bead lubricants for Die Casting. Our product portfolio comprises several graphite-based beads and white beads, available in different sizes and solid content:

All FOCHEM INTERNATIONAL plunger beads consist of a high melting point synthetic wax. The globules are perfectly round and free flowing, anti-static and dust-free. They are suitable for tropical conditions.

Advantages of FOCHEM INTERNATIONAL beads:

  • Effective protection of the shot sleeve against aluminium erosion
  • Minimisation of casting porosity
  • Only small amounts required

In recent years we have revolutionised the lubricating quality of all our beads through an improved and exceptionally innovative manufacturing process. Our customers are now provided with highest quality beads for a reliable application.

We strongly recommend to use the FOCHEM INTERNATIONAL “Beads Dispenser 3D” in conjunction with our beads.

The “Beads Dispenser 3D” is a digital beads dosing machine offered to the Die Casting industry, manufactured by our associate company TRIBO-CHEMIE GmbH in Germany.
It is equipped with a technologically advanced dosing head, 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.

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.

In many countries our products can be obtained through distributors. Where no representation is in place our products can be ordered directly from FOCHEM INTERNATIONAL, South Africa.
