At a glance

Protect the inside. Preserve cooling performance.

Prevent corrosion

A thin protective coating protects the internal surfaces of the cooling channels.

Delay deposits

The treatment targets the formation of limescale, dirt deposits and biofilm.

Maintain cooling performance

The aim is to largely maintain flow and heat transfer.

Stabilise service life

More consistent cooling conditions reduce the need for unplanned maintenance.

Especially relevant for

  • Varying water quality
  • Uneven temperature control
  • Preventive protection for new moulds
  • Maintaining existing moulds

Thin protective coating

Protection where the cooling water flows.

Approximate coating thickness12–15 µm

Flow and cooling performance are largely maintained.

New mould

Protect preventively.

Treat the internal surfaces of the cooling channels before series production starts.

Existing mould

Complement maintenance.

Assess suitability based on channel condition and observed deposits.

Principle & application

The technology behind it.

01Why cooling circuits need protectionCorrosion and deposits can impair flow and heat transfer.

Moisture, temperature changes and varying water quality can cause corrosion, deposits, limescale and biofilm in cooling channels.

Narrowed or corroded channels impair flow and heat transfer, potentially affecting process stability, cycle time and part quality.

02Thin protective coating for internal surfacesApproximately 12–15 µm of protective coating on the internal surfaces.

AnoxPro protects the internal surfaces of cooling channels with a thin, durable coating. It is designed to prevent corrosion and delay deposit formation without significantly impairing the function of the channels.

The coating thickness is approximately 12 to 15 micrometres. Cooling performance and flow are largely maintained.

  • Corrosion protection
  • Delay limescale and bacterial deposits
  • Maintain cooling performance
  • For new and existing moulds
03Prevention and maintenancePreventively for new moulds or as part of maintenance.

AnoxPro is suitable as a preventive measure for new moulds and as part of maintenance for existing moulds. The aim is less unplanned maintenance, more stable cooling conditions and a longer service life for temperature-controlled mould areas.

04Technical assessment for your applicationWhen temperature control becomes an issue

Long-term care for cooling circuits.

Moisture, temperature changes and varying water quality can promote corrosion and deposits in cooling channels. Changes often go unnoticed for a long time and can impair flow and heat transfer.

  • Protection of internal surfaces

    The treatment is designed to prevent corrosion and delay deposits, limescale and biofilm formation.

  • Preserving function

    The protective coating is applied so that flow and cooling performance are largely maintained.

  • New and existing

    AnoxPro is intended both for new moulds and for existing moulds as part of maintenance.

If flow decreases, temperature control is uneven or deposits recur, the suitability of cooling-channel treatment can be assessed for the application.

Selection depends on the plastic, tool material, geometry, temperature, mechanical loading, cleaning conditions and desired function.
