coatings for plastic and aluminum injection molding

The THERMILYON Group has developed a complete range of coatings, Platin'®, to meet the wear problems encountered inplastic injection molding andaluminum and zamacinjection molding.

For plastic injection molding, we have designed a range of deposits to suit the plastic materials injected and the fillers (fiberglass, for example). Our solutions improve the demoldability and quality of injected parts.

Thermi-BugeyThermi-Bugey, located in the heart of Plastics Valley since 1987, gives us in-depth knowledge of the plastic injection industry.

For the aluminum die-casting sector, our coatings have been designed to limit tinning and thermal cracking due to injection temperature. Our multi-layer coatings prevent crack propagation, and their titanium-aluminium-based chemical composition ensures good heat resistance properties.

Solutions to your problems

For plastic or non-ferrous injection molds, our coatings offer real advantages:

01

Coatings for plastic injection moulding

- High hardness reduces erosion of mold walls by the injected material.

- Low chemical reactivity, limiting plastic bonding phenomena

- Good corrosion resistance, limiting mould degradation when injecting fluorinated or chlorinated materials

- Low coefficient of friction eliminates seizing of moving parts

02

Coatings for non-ferrous injection molding

The recommended PLATiN® coatings have:
- Very high hardness, even at high temperatures, to limit wear caused by abrasion.
- Low chemical reactivity, to limit sticking of the injected materials.
- Multilayer structure , to improve resistance to thermal shock.

For this application, we strongly recommend nitriding the
substrate before coating (DUPLEX treatment).

The MOLDIN' range is produced on new equipment allowing PREMIUM coatings to be produced as well as DUPLEX In Situ treatment (nitriding + coating in the same cycle):
- no intermediate polishing or grinding
- no intermediate transport

For moving parts the
THERMI®-DLC range (carbon-based coating) provides anti-seize and anti-wear solutions.

Our recommendation

We strongly advise you to contact our
specialists to determine the most suitable treatment for both
coating and
surface preparation. Indeed, some
injected plastics require specific preparation before
and after coating (including
poli-glazed surfaces).

    advantages of platin'® coatings for injection moulding

    PLATIN'® coatings offer the following advantages to plastic injection and non-ferrous mechanics:

    improved service life

    Longer tool life thanks to improved wear resistance.

    respect for the environment

    Elimination of harmful release agents
    for the environment.

    Manufacturing quality

    Improved manufacturing quality and reduced non-quality costs.

    cost reduction

    Reduce production costs by cutting
    cycle times.

    Reduced maintenance frequency and time.

    Lower material costs for DUPLEX MOLDIN' coatings

    Our FAQs

    What is vacuum deposition?

    Vacuum deposition is a surface treatment used to deposit a material or alloy on a mechanical part.

    The use of vacuum technology ensures a perfectly clean, non-polluting process.

    It is not subject to REACH legislation.

    What are the advantages of PVD technology?

    This process greatly increases resistance to wear, abrasion, friction and corrosion. As a result, component life is greatly extended.

    Standard thicknesses are of the order of 3µm and deposition is carried out on finished parts.

    What's the difference between PVD and PACVD?

    PVD is physical vapor deposition. The element to be deposited is obtained by evaporation or sputtering via a physical process. PACVD is plasma-assisted chemical vapor deposition. The element to be deposited is obtained from chemical reactions. Plasma enables this chemical reaction to take place at lower temperatures.

    What are the industrial applications of vacuum deposition?

    Vacuum deposits are classified into several categories: anti-wear, friction, decorative and biocompatibility. The applications are therefore very varied: automotive components, aerospace, tooling, cutting tools, medical devices, decorative parts...

    How do I choose the right deposit method?

    The deposition method depends above all on the nature of the coating to be deposited and the substrate.

    If the substrate cannot be heated to high temperature, the deposition must be carried out using low-temperature technology.

    If the coating to be deposited consists of a solid element (metal or graphite target), a physical process such as PVD is used. If the coating consists of a gas or liquid, a chemical process such as CVD or PACVD is used.

    What is the purpose of case-hardening? 

    Incorporate carbon below the surface of the steel part to improve fatigue and wear resistance on the surface, while maintaining good core mechanical properties.
