Advanced and Precision Manufacturing
Injection moulding is an advanced and highly precise manufacturing technology used to produce technical components from rubber, silicone and plastics. The process involves injecting the material into a closed mould, enabling the manufacture of components with outstanding dimensional accuracy and consistent quality. This technology is ideally suited for producing both simple seals and complex components with intricate geometries.
Why Choose Injection Moulding?
Injection moulding enables manufacturers to achieve outstanding quality, consistent repeatability and cost-efficient production. The key advantages of injection moulding technology include:
- high production repeatability,
- the ability to manufacture millions of identical components,
- excellent dimensional accuracy and precision,
- high productivity through process automation,
- reduced material waste,
- the ability to produce complex geometries,
- low unit costs for high-volume production,
- compatibility with a wide range of engineering materials.
At GUMOTIV, we manufacture components from rubber, silicone and plastics using advanced injection moulding technology.

Tooling and Injection Mould Design
A key stage in production preparation is the manufacture of prototype and production tooling. For more than 15 years, we have worked with a carefully selected group of specialist toolmakers who continuously develop their expertise in precision machining and operate state-of-the-art equipment, including 5-axis machining centres, CNC milling machines, CNC lathes, wire EDM and sinker EDM machines. Our experienced tooling specialists, with extensive knowledge of injection moulding technology, ensure reliable project execution and on-time delivery.
GUMOTIV’s engineering department designs injection moulds, production fixtures, inspection tools and complete manufacturing lines, while supervising their production by our tooling partners. Hundreds of successfully completed projects have built our expertise and continue to create new opportunities for efficient and innovative manufacturing of rubber, silicone and plastic components.
How Does the Injection Moulding Process Work?
Injection moulding is a highly automated manufacturing process used to produce large volumes of identical rubber, silicone and plastic components. Depending on the material, each production cycle may take from a few seconds to several minutes. Regardless of the material being processed, the injection moulding process consists of seven key stages:
Stage 1 – Material Preparation
The raw material, whether plastic granules, rubber compound or silicone compound, is prepared for the manufacturing process. The material must meet the required processing characteristics and quality specifications.
Stage 2 – Material Plasticisation
Inside the injection unit, the material is heated and brought to the required processing consistency. Processing temperatures typically range from approximately 180°C to 350°C for plastics, while rubber and silicone compounds require individually optimised processing parameters.
Stage 3 – Injection into the Mould
The material is injected into the closed mould under high pressure, which can reach between 500 and 2,500 bar. This allows even highly complex geometries to be reproduced with exceptional precision.
Stage 4 – Cooling or Vulcanisation
Once the mould cavity has been filled, the material is cured. For plastics, this involves cooling, while rubber and silicone undergo a vulcanisation process. This stage determines the final mechanical properties of the finished component.
Stage 5 – Mould Opening and Part Removal
At the end of the production cycle, the mould opens automatically and the finished component is removed using ejector pins or an industrial robot. In modern manufacturing facilities, this process is fully automated.
Stage 6 – Quality Control
The finished components undergo dimensional, visual and functional inspection. Depending on customer requirements, quality checks may include dimensions, hardness, sealing performance and compliance with technical documentation.
