Solutions for die casting

Ejector lubrication

  • Ejector lubrication

    Our high-temperature ester-based oils are versatile lubricants for industrial applications, typically used for ejectors and moving mould components. Thanks to their excellent thermal stability, they are ideally suited for metal die casting, even under high process temperatures.

    Product characteristics

    • Excellent adhesion and creeping behavior
    • Residue-free application
    • Available in liquid form or as a spray

  • Squeeze pin / Hot-spot lubrication

    For reliable lubrication of squeeze pins and hot sports, we offer specialized products that provide effective lubrication even with minimal material usage and are suitable for series production.

    Product characteristics

    • Semi-synthetic, water-based formulations
    • Free of silicone, wax, and solvents
    • Minimal material consumption with high performance
    • Specifically designed for squeeze pins and hot spots

  • Punching oils and cutting fluids

    For lubrication of punching tools used with aluminium, zinc and magnesium die castings, we provide solvent-free punching oils and water-based emulsions. Our products offer excellent creeping properties and do not resinify.

    Product characteristics

    • Ready-to-use
    • Excellent lubrication performance
    • No residues in mould cavity
    • No leftover oil on tools or cast parts
    • Superior creeping behavior
    • Odorless
    • No build-up, no resinification
    • Partially biodegradable

  • Anti-solder pastes

    Our anti-solder pastes are designed specifically for non-ferrous metal casting. They contain no solvents, sulfuric acid, or silicone oil and provide reliable protection against metalization and erosion.

    Product characteristics

    • Sulfuric acid-free
    • Prevent metalization
    • Excellent adhesion to mould engraving

  • Additives for cooling basins

    To protect against bacterial growth and corrosion, we offer water-miscible cooling fluid concentrates. Special additives reduce the surface tension of water, facilitating efficient blow-off of cooled cast parts.

    Product characteristics

    • Facilitate easy blow-off of cast parts
    • Effective corrosion protection
    • Protect against bacterial growth
    • Cleaning effect
    • Water-miscible, typical dilution 1:100

  • Cleaners

    Our cleaning product range includes powerful universal cleaners for the metalworking industry – for degreasing metal and plastic surfaces (painted or unpainted) as well as for cleaning central die casting release agent supply systems.

    Product characteristics

    • Excellent solvency
    • High flash point
    • Water-miscible
    • Low odor

Plunger Lubrication

Plunger lubrication

Solutions for die casting

Optimal plunger lubrication is a key factor for a stable and efficient casting process.
High-performance plunger lubricants ensure smooth and consistent die filling. At the same time, they reduce energy consumption during the shot and significantly extend the service life of plungers, plunger rings, and shot sleeves.

Plunger lubrication

  • Water-based plunger lubricants

    • Ready-to-use
    • Oil-wax-based emulsion
    • Excellent lubrication and creeping properties
    • Low consumption
    • Clean surroundings due to water-soluble formulation

  • Oil-based plunger lubricants

    • Excellent adhesion properties
    • Homogeneous lubricating film with outstanding performance
    • Ideal for high plunger temperatures
    • Very good emergency running properties
    • Extended shot sleeve lifetime
    • Suitable for minimum quantity lubrication
    • Available in various viscosities

  • Plunger lubrication with pellets

    • Wax-based with high-performance lubricant additives
    • Excellent lubrication properties
    • Suitable for all plunger sizes, especially large diameters
    • Reduced plunger wear

Application of water-based plunger lubricants

Our water-based plunger lubricants can be flexibly adapted to your individual process conditions.
They are typically applied directly onto the plunger, ensuring optimal surface wetting. Depending on process requirements, application can be carried out either into the shot sleeve or directly onto the plunger.

  • Application to the filling chamber on the mould side

  • Application to the filling chamber on the plunger side

  • Application to the plunger

Release agents / Short-Spraying / Micro-lubrication

Release agents / Short-spraying / Micro-lubrication

Solutions for die casting

High-quality release agents are essential in die casting and play a decisive role in ensuring component quality.
Long mould life and minimal application quantities (micro-lubrication) are key factors for the economic efficiency of your production.

Water-based mould release agents

Our portfolio focuses on cost-efficiency and process performance. By carefully selecting modern, high-quality raw materials, further processing of the cast parts – such as coating, painting, or bonding – is possible without additional surface treatment. Using our release agents enhances both the optical and physical properties of your final products.
We offer ready-to-use products as well as concentrates for aluminium, magnesium, and zinc die casting.

Release agents / Short-spraying / Micro-lubrication

  • Release agents for aluminium

    • Fully synthetic, wax-reduced, silicone-free, or wax-free formulations
    • Water-based
    • Minimize residues in cavity and mould joints
    • Excellent release and lubrication properties
    • Optimal spreading and creeping behavior

  • Release agents for magnesium

    • Fully synthetic, wax-reduced, silicone-free, or wax-free formulations
    • Water-based
    • Ensure bright and uniform surfaces
    • Excellent release and lubrication properties
    • Superior spreading and creeping behavior

  • Release agents for zinc

    • Water-based, wax-free
    • No residues in cavity and mould joints
    • Bright cast parts
    • Prevent casting skin flaking and flow defects

Short-spraying

To facilitate the transition from conventional water-miscible release agents to micro-lubrication, we recommend short-spraying as an intermediate step.
Our water-based emulsions offer excellent creeping behavior and effectively prevent build-up of release agent on the mould frame.
Delivered primarily as concentrates, they are especially cost-efficient.


Benefits of short-spraying
  • Uses conventional spraying equipment
  • Cools hot spots
  • Reduces spray quantity by up to 90%
  • Shortens cycle time
  • Reduces wastewater

Micro-lubrication

Micro-lubrication significantly reduces release agent consumption compared to conventional water-miscible products.
Application is performed using precise dosing systems that atomize the agent finely and deliver minimal quantities. Since heat is no longer removed via the release agent, additional mould cooling measures are required, such as internal cooling circuits.


Benefits of micro-lubrication
  • Very low material consumption
  • Extended mould life due to stable temperature conditions
  • Improved cast part quality, reduced porosity
  • Faster production cycles with shorter spray and blow-off times
  • Lower storage costs
  • Oil-based products: frost- and bacteria-resistant, stable shelf life
  • Easy handling: no water mixing or complex water treatment require


Our portfolio includes both water-based and oil-based release agents for minimum quantity lubrication.

Release agents / Short-spraying / Micro-lubrication

  • Water-based products

    • Ready-to-use
    • Oil-in-water emulsions, wax-free or wax-containing
    • Excellent creeping behavior
    • High performance

  • Oil-based products

    • Fully or partially synthetic, wax- and silicone-free
    • Solvent-free
