Packaging

Cycle time and reliability at the core of our moulds

In the packaging industry, cycle time, precision and reliability are crucial. The market demands lightweight, strong and aesthetically high-quality packaging, produced in massive volumes with minimal error margins. Tumag designs and manufactures high-quality moulds that meet the strict requirements of thin-wall products, capsules, vials, screw caps, closure mechanisms and other complex packaging components. With our expertise in mould building, toolmaking, HSM milling, turning, cylindrical and profile grinding, and both wire and sink EDM, we produce moulds capable of efficient, repeatable manufacturing of both small series and high-volume production.

Our approach focuses on optimally controlling material flow, cooling and mechanical load in order to minimise cycle time without compromising quality. By integrating simulation and technical analysis early in the design process, we can perfectly tune critical areas — such as thin rib structures, sealing surfaces or thread integrations — to the injection moulding process.

Complex solutions for multi-component and 2K products

From single-cavity moulds to multi-cavity systems and high-end spindle moulds, our solutions support even the most demanding packaging designs. Packaging products are rapidly evolving towards multifunctionality, and with our 2K and multi-component technology, we can combine different materials, colours and hardness levels within a single mould. This allows us to realise functions in a single cycle, such as:

• integrated 2K seals,
• click and twist closures,
• soft-touch grip zones,
• wear- and scratch-resistant hinges,
• flexible tabs or dosing elements,
• and aesthetic effects like transparent windows or multi-layer visuals.

Since these functions are created directly in the injection moulding process, many post-processing steps disappear or are significantly reduced. The result: shorter lead times, lower defect rates and a highly optimised production chain.

Cooling technology, wear management and long service life

High output requires moulds that are not only precise but also durable and wear-resistant. That is why we pay special attention to cooling technology, flow channels, coatings and material selection — such as hardened steel, corrosion-resistant alloys or specialised coatings suitable for abrasive or recycled plastics. By strategically placing cooling circuits and applying variotherm or conformal cooling techniques where necessary, we achieve shorter cycle times and highly stable product behaviour.

We also give extra care to wear-sensitive areas such as sealing surfaces, threads or ultra-thin ribs. Through precise finishing and regular, documented maintenance instructions, the service life of our moulds is significantly extended.

High output and consistent accuracy

Our moulds are designed for high cycle rates, consistent precision and stable performance — essential for packaging components used daily by consumers. With our extensive experience in multi-cavity moulds, 2K technology, injection moulding, small-series production and precision machining, we guarantee optimal product quality, cost reduction and structural repeatability.
