We have our own technological facilities for the manufacturing of injection molds.
We perform product design and 3D modeling in-house.
We do not outsource any stage of the production process to external companies.
Full process control allows us to optimize lead times and project costs.
Injection molds are built exclusively for serial production carried out at SIGERN.
This allows us to offer a complete production implementation process – from part design and 3D modeling, through mold manufacturing, to serial plastic injection molding or aluminum component production. This approach ensures the highest quality and long service life of the mold, since all maintenance, adjustments and repairs are handled in our in-house tooling department, without delays and without transporting the tool outside the facility.
We invite companies that expect professional, stable and responsible production support — with guaranteed quality, reliable delivery and full commitment.
Injection molds are a key element of stable serial production. Their design, manufacturing precision and durability directly influence the quality of molded parts, cycle time and unit cost. Mold design is carried out with consideration of part geometry, material type and the expected production volume. This ensures predictable and repeatable tool performance, reducing the need for corrections during production.
We design and manufacture injection molds tailored to different production requirements, including:
Each mold is designed individually, with a strong focus on process stability and long tool life.
The mold development process is based on clearly defined stages, ensuring full control over both quality and delivery timelines.
This approach allows the mold to reach reach stable operating parameters quickly and helps avoid unplanned production downtime.
Injection molds are designed for long-term, stable operation. The selection of tool materials, cooling systems and guiding components takes into account the requirements of serial production.
Our in-house tooling department enables:
Combining mold design and manufacturing with component production within one organization allows real operating conditions to be considered already at the design stage. Injection parameters and mold geometry are optimized in parallel, which shortens the time required to launch and stabilize production.
For many years, we have been delivering projects in plastic injection molding and injection mold manufacturing for a wide range of technical industries. We also undertake complex and unconventional projects, including solutions protected by patents. Our design and manufacturing experience enables us to implement components that require high precision, durability and repeatability.
We deliver components that meet strict quality and functional requirements, in compliance with the standards applicable in the client’s industry. Our reliability is confirmed by references from our clients that have entrusted us with both serial production and new product implementations — from design to the finished component.
All stages — mold design, tool manufacturing, injection molding and finishing — are carried out at our facility in Poland. This gives us full control over quality, shortens implementation time and ensures stable deliveries. Clients can follow the entire product development and production process in one place.
We invest in automation and precision machining technologies. Our tooling department is equipped with modern CNC machining centers, EDM machines and equipment for precision finishing of injection molds. Serial production is carried out on energy-efficient injection molding machines with robots and automated systems for material feeding and drying, ensuring high mold quality and long service life.
We operate a tooling department specialized in the production of injection molds and their key components, including inserts, sliders and tooling elements. The core of the process is CNC machining, which ensures high precision, repeatability and full compliance with technical documentation — essential for serial production.
We use CNC milling and turning, drilling, grinding and EDM (electrical discharge machining), which enables the production of precise cavities, sharp angles and components with complex geometry, including hardened tool steel. The combination of CNC and EDM technologies allows us to achieve accuracy down to hundredths of a millimeter.
Machining affects not only geometry but also surface quality, tool durability and the stability of the mold during the injection molding process. Each stage is preceded by an analysis of the material, tolerances and design requirements, allowing us to select machining parameters that ensure mold components are perfectly matched to future serial production.
→ CNC and EDM machining in our tooling department is performed exclusively for the production of injection molds intended for further serial production of plastic or aluminum components at SIGERN. We do not accept subcontract machining orders or produce individual custom parts as a standalone service.

Injection molds for plastics are the foundation of stable and repeatable serial production.
Clients looking for a reliable supplier expect above all: short lead times, predictable costs, long mold life and a secure injection molding process.
SIGERN designs and manufactures injection molds in its own tooling department, which allows us to maintain full control over quality, servicing and delivery timelines, while avoiding subcontractors — and therefore minimizing the risk of delays.
We design injection molds for a specific component, material and production volume. This means we select the number of cavities, durability class, cooling system and runner technology (cold or hot runner) to achieve the shortest possible cycle time and the lowest unit cost of the component.
The injection molding process itself typically takes place at plastic temperatures of 180–350°C and injection pressures reaching up to 1000 bar. For this reason, molds are manufactured from specialized tool steels with increased strength, designed to withstand both thermal and mechanical loads.
