Injection Molding Technologies

Injection Molding is a Process that is Mainly Used in Plastics Processing

In this process the respective material is liquefied and injected into a mold under pressure. Hörl Kunststofftechnik GmbH & Co. KG, part of the Rosenberger Group since 2010, specializes in the production of innovative and high-precision plastic injection molded parts of consistently high quality. The fully automated production of small and micro injection molded parts made of engineering plastics is carried out in a digitally networked production unit which is centrally controlled and monitored. A self-imposed zero-defect strategy demonstrates the company’s clearly structured quality management system combined with comprehensive know-how.

What is Injection Molding Technology?

The desired end product is created by melting plastic granules of thermoset or thermoplastic polymers followed by injection under pressure into a mold and subsequent cooling. A major advantage of injection molding technology, in addition to high production accuracy and volume, is the ability to reproduce complex shapes and geometries.

The production is carried out with maximum accuracy so that no post-processing of workpieces is necessary. With injection molding technology customer requirements can be maximized as the choice of plastics available is very extensive. The continuous development of new plastics leads to an ever-increasing range of applications for this technology.

Production

When it Comes to Production, Injection Molding Technology is Fully Automated at the Rosenberger Group

Innovative developments with regard to Industry 4.0 guarantee the highest quality standards: A master computer system monitors and controls all production processes; information on deviations from production parameters is transmitted in real time. This ensures stable processes and a zero-error strategy.

Accordingly, the Rosenberger Group stands for state-of-the-art processes that enable the precise fully automated assembly of high quality individual components to finished products. There are no limits to customer requirements, from micro injection molding to large components. Hörl Kunststofftechnik is a competent technology partner utilizing state-of-the-art equipment, fully capable of implementing even the most complex production requirements with maximum efficiency.

Tool Technology

Competence meets precision: The fully digital toolmaking department enables the design of highly complex injection molding tools. For example the manufacture of multi-cavity molds allows the production of up to 64 injection molded parts in just one machine cycle.

Quality Management

Quality requires responsibility and is a major focus of the Rosenberger Group. Hörl Kunststofftechnik’s quality management is therefore certified according to IATF 16949 and ISO 9001. In addition, optical and tactile measuring methods are used in the production process such as tomography, not only to maintain high quality but also for continuous optimization. Delivering top quality means understanding customer requirements and being able to demonstrably deliver technical expertise at any point in the production process.

Environmental Protection

Success with Responsibility: In its Role as a Globally Operating Industrial Company the Rosenberger Group Recognizes its Responsibility for Protecting the Environment

Recycling and energy efficiency are decisive issues in the field of injection molding. Therefore, continuous improvement processes and efficient process monitoring systems serve to conserve resources and promote sustainability. In addition, heating at Hörl is carried out with energy from heat recovery systems while cooling and air conditioning take place using well water. Up to 30% of the electricity required is generated by the company's own photovoltaic system. Any plastic waste generated is recycled and reused (re-granulation).
