Plastic injection moulding: advantages for your project
The main advantage of plastic part manufacturing using the injection moulding process is the ability to create immediately usable moulded parts in a single operation. This makes injection moulding ideal for automation. It enables high-precision individual parts to be mass-produced more cost-effectively while maintaining consistent quality. Surface structure and material properties are freely selectable. Reworking is only necessary to a limited extent, if at all.
REINER® specializes in the injection molding of plastics for small technical components with high precision requirements. The production of such plastic parts with very small dimensions is particularly economical and uncomplicated when injection moulding is used. In plastic injection moulding, many different materials are available for the realization of individual customer requirements:
Which material property is achieved with which plastic?
Elastic moulded parts
Polyolefins such as polypropylene (PP) result in elastic moulded parts to a certain degree.
Transparent moulded parts
Plexiglas (PMMA) and polycarbonate (PC) are used as transparent moulded parts, such as display panels.
Hard moulded parts
Polystyrene (PS) are used in many toys with harder properties, such as LEGO bricks, and household appliances.
Technical applications
Polyamide (PA), polyoxymethylene (POM) and other engineering plastics are used in mechanical and electrical engineering.
Know-how: Plastic injection moulding explained in brief
Injection moulding is a thermoplastic moulding process for plastics. It is one of the most frequently used production processes for manufacturing plastic parts. Modern industry would be unthinkable without it due to its cost-effectiveness and reliability.
How does injection moulding work?
In plastic injection moulding, plastic granules are pressed into a tool under pressure and heat to take on a specific shape. To do this, the granules are first heated and melted. The thermoplastic mass is fed into the moulding tool via a filling funnel. The injection-moulded part solidifies through cooling or a cross-linking reaction and is then ejected. The plastic part produced in this way is often ready for immediate delivery without any loss of time and does not require any post-processing. The properties of the plastics used in injection moulding can be adapted as needed using additives and fillers.
In multi-component injection moulding (2K injection moulding), two or more different plastics are combined. This allows components with multiple properties to be produced in a single operation. In the simplest case, the respective plastics differ only in color. Combinations become particularly interesting when different physical, elastic or haptic properties are involved.
What characterizes high-quality injection moulding tools?
Not all moulds are the same: the smallest differences in the quality of injection moulding tools can have a significant impact on the finished components. In particular, it must be taken into account that plastic components contract slightly when cooling. This makes it easier to remove them from the tool mould. However, this “shrinkage” must be precisely calculated and taken into account in the mould design as early as the tool design stage.
Depending on the complexity of the components to be manufactured, injection moulds must be designed with great foresight. If necessary, special mechanisms for removing the cooled components must be planned. In addition to conventional ejectors, flat ejectors and scrapers, sliders or angled ejectors are also used. Complex moulded parts with an “inner life” are created using threaded cores or collapsible cores.
Toolmaking itself uses aluminum and steel materials to make the tools. Aluminum is more cost-effective for small-batch production, but it is less dimensionally stable and durable than steel. Steel is significantly harder, but also more difficult to machine. It allows for more specialized surface structures and higher quantities.

We would be happy to advise you in detail on the individual design of the moulding tools for your components.
From what batch size does it become economical to have injection-moulded plastic parts manufactured?
The injection moulding process is suitable for manufacturing a wide range of components. It is used in a wide range of industries, including medical, hand/power tools, aerospace, defense, sensor and locking technology. Since any number of parts can be produced with a single mould, the process is particularly suitable for larger batch sizes (from 25,000 pieces) with high precision requirements.
That is why customers rely on REINER®, the plastic parts manufacturer
The REINER® brand is known as a leading manufacturer of durable stamps, marking devices and self-service scanners. For over 100 years, REINER® has placed special demands on the small and often complex precision components required for this.
