frequently asked questions about matriq’s DynamicMold (DM) technology

Is marking mandatory?

Marking plastic products with a unique device identification (UDI) is enforced by regulations for an always increasing number of products, especially in the medtech and in-vitro diagnostics market. The rationale behind is clear: quality control and traceability. In other sectors, such as automotive and industrial, having a unique identification code on each part would ease the management of recall campaigns and the association to its origin and manufacturing parameters.

Which plastic forming process is the DM technology compatible with?

The DM-technology was originally conceived for marking in injection molding processes.
However, thanks to its versatility and plug-and-play nature, it is compatible with other plastic forming processes such as thermoforming, blow molding, and hot embossing. We are optimizing its features to enable integration in such processes.

Which type of products can the DM insert mark?

We can mark any product totally or partially made of plastics. We are providing our marking services for different applications: MedTech, life science, pharma packaging, automotive, consumer goods, and industrial.

Does the DM product require additional space or infrastructure?

As a strong advantage, marking by matriq’s DM technology needs no additional footprint at the production site. It does not require any additional equipment nor process steps and happens within milliseconds, right inside the fabrication machine, not affecting the product cycle time, thus freeing space for equipment in the production area.

Which polymer types can the DM technology mark?

The DM-insert has been validated for marking PS and allows to achieve marking also in other polymers and copolymers such as PET, ABS and COC. Marking PP proved to be more challenging, however an optimized contrast mechanism is currently under development to enable such polymer marking.

Are fibre- or particle-filled (reinforced) polymers markable by DynamicMold? To what filling factor?

We will develop the DM technology to be suitable for any polymer and application. We are bringing DM to the level of universality concerning polymers, fillers, forming processes, high code quality and long-lasting performance by adjusting our contrast mechanism and certain hardware features. Today, we use a particular contrast-generating method that works with a range of polymers (PS, PET, ABS, COC) but has a limited quality for PP. The determining factor is the flow curve / viscosity plot of the polymer to be molded (dependence of shear force on shear rate and how the viscosity depends on the shear rate).

Is it possible to mark curved objects?

It depends on the curvature radius. Our actual inserts have a diameter of 8 mm and require a flat surface matching their diameter. However, we are able to mark curved objects with a relatively large radius, by offering inserts with smaller footprints (4 mm) and designing a flat spot on the plastic piece. In the case of a smaller radius, when introducing a flat surface is not page 2 compatible with the forming process, curved (cylindrical) shapes for our insert could be envisioned, but this represents an engineering challenge.

What hardware is necessary to install DM marking?

Marking by matriq’s DM requires only three hardware pieces: the DM insert to be mounted into the mold cavity (for multi-cavity molds, many inserts can be mounted, one per each cavity), the cable(s), and the control unit. We provide a unit capable of operating as many inserts as needed.

What is the lifetime of the DM-insert before replacement is required?

Today, the DM-insert lifetime is shown to have more than 100’000 cycles. We are currently testing enhanced insert variants with coding durability of at least 500’000 cycles, with a final target of over one million shots per insert. We use state-of-the-art hard coatings to enhance the durability of the mold inserts.

Which types of code can the DM-insert enable?

The DM-insert allows marking of different types of codes: digital dates, QR-codes and DataMatrix codes. Moreover, we are able to integrate optical features to embed your company logo in our marking and enable brand trust. This is particularly suitable in case your product is facing copyfraud.

What is the smallest size of codes matriq can provide?

Our first product DM-date will issue – as the name suggests – a digital date on the plastic product surface. This type of code will occupy an area of 20 mm2 (4x5). The next generation codes (DataMatrix or brand embedded codes) will occupy an area of 4.3x4.3 mm2 (14x14), according to the design of our flagship product, the DM-qode. Even if it is possible by our technology to have other designs and sizes for codes, we are today focusing on a 14x14 DataMatrix code generator in a 8mm round diameter housing for 3Q2022.

Is particular software available?

DM hardware is complemented by a software and GUI allowing the machine operator to monitor the marking process. Several key parameters are adjustable to choose between the different pattern possibilities and achieve the highest code quality on the final part. The status of all inserts can be observed at any time.

What interfaces / connectivity is DM providing?

DM is operated by a control unit independent on the machine and mounted on the outer side of the mold. Single cables connect all the inserts mounted in the mold cavities to it. The control unit only needs a power supply and can handle the marking completely autonomously. The inserts are indeed equipped with temperature sensors monitoring the molding/forming process and selftriggering the issuance of the code. The connectivity to the MES and ERP systems of our customers can be offered together with the entire traceability ecosystem.

How can the code be read?

Process data (e.g. temperature, pressure) and origin parameters (raw material, supplier, etc.) of the specific product are stored - linked to the issued code - in a cloud infrastructure and can be retrieved by scanning the code (for DM-qode) along the value chain as well as by the product final user. Industrial cameras or standard handheld readers can read the DataMatrix code. This allows the connectivity of our marking solution to the fullest along the whole value chain.
