Putting research mould into operation

Putting research mould into operation

An important milestone consists in putting the research mould, which has been built by CAD-PLAST in the laboratory of ENGEL Austria GmbH in 4311 Schwertberg/Austria, into operation. Before this first process analyses were made by using a test mould provided by HTBL Kapfenberg. The first EXJECTION components are manufactured. The process is acknowledged in its function. Building of the research mould ready for series production has been supported by the Special Steel Corporation BÖHLER-UDDEHOLM, the coating specialist OERLIKON BALZERS COATING, both Kapfenberg/Austria, as well as by the manufacturer of gauges HASCO, Guntramsdorf/Austria, and KISTLER Company, Winterthur/Switzerland. Important process relevant components of the EXJECTION mould can favourably be integrated in an injection moulding machine. This increases economic efficiency in terms of the scope of investment and manufacturing costs even more.

Demonstrating suitability for series production

Demonstrating suitability for series production

For the first time EXJECTION components with a wall thickness of 1.2 mm and a length of 930 mm are manufactured in a high quality by using the rebuilt research mould. Thus suitability for series production of the EXJECTION Process is demonstrated! Systematic process analyses on an ENGEL e-motion injection moulding machine show the expected good influence on the process. Different types of thermoplastics are processed by means of the new process. There always is the same result, which is extremely positive: The quality of the components meets the high market requirements. Serveral materials got tested, such as ABS, SAN, PMMA, IONOMER, PC, TPU, PBT, PA and PP.

The organizer, DI Gottfried Steiner, CEO of IB STEINER presented facts that backed up the superior capabilities of the EXJECTION process both economical as well as from a technical view.

Federal Award Consulting 2009 for IB STEINER

Federal Award Consulting 2009 for IB STEINER

The Federal Award Consulting 2009 was presented by State Secretary Christine Marek in the Studio 44 in Vienna on November 23th, 2009. BMWFJ (Federal Ministry for Economic Affairs, Family and Youth) recognizes outstanding engineering performance by presenting the Federal Award in co-operation with ACA. It is IB STEINER that obtained the Federal Award for Engineering Consulting 2009 as a reward for the development of the EXJECTION Technology. This Award did not only emphasize the significance of the new technology but also placed the efficiency of the project partners in the limelight. Excerpt from the assessment made by the jury: ... On the one hand, energy efficiency is improved significantly (about 60 % of energy can be saved, which also has a correspondingly positive effect on the environment). On the other hand, lower investment costs (approx. 40 % as compared to conventional injection moulding machines) also help to lower the manufacturing costs for the plastics parts manufactured by using EXJECTION. In the interview with ACA, DI Gottfried Steiner explained, "Innovative technologies enable us to remain competitive on the world market. This plastics and innovative manufacturing technologies are very important for our future in the heart of Europe."

EXJECTION endless | Continuous Production

EXJECTION endless | Continuous Production

Continuous injection moulding becomes reality: Based on the idea of the moving cavity, the EXJECTION endless technology surmounts all limits so far set by the moulding cycle. The modular design of the EXJECTION endless mould makes it possible to demould already cooled and frozen segments of the moulded component while at the gate continuously new product is generated. Those segments of the cavity, where the component has already been demoulded, are transferred back to their initial position at the front end of the cavity. There they again generate new cavity, ready to be filled up again with melt. This way a discrete process becomes continuous. Development and realisation of the first mould, which has been brought into operation in July 2010, have been done in cooperation with the SAARGUMMI group, one of the leading suppliers of automotive sealing solutions and the Z-WERKZEUGBAU GmbH, one of Austria's leading mould makers. There the results of the development finally became reality. Nozzle insert and hot runner system were provided by the well established EXJECTION partner HASCO GmbH. Already the production of the very first 1.000 meters made clear that the process offers a very special charm.

Serial maturity for continuous production

Serial maturity for continuous production

EXJECTION now continuous: 2007, INGENIEURBÜRO STEINER presented EXJECTION technology for the first time to the market, which makes it easy to manufacture products with 2 or 3 meters length on small injection moulding machines. In early July 2011, the first EXJECTION endless mould was operating on an injection moulding machine of ARBURG. This technology overcomes existing limits in injection moulding processes. For the frist time worldwide, continuous moulding is REALITY: production of components on a roll without dry cycle times for mold closing, mold opening and part removal. The process is entirely sufficient and reinforced already in first projects .

The areas of application for the EXJECTION endless process are manifold. Whether it is automotive, aerospace , electrical and electronics, construction or medical technology, for each sector it is easy to represented clearly the benefits. This applies to the component developer, who has access to unprecedented design possibilities and new functionalities, as well as to the business administration with lower manufacturing costs and higher production capacity. The development of EXJECTION towards continuous production shows the enormous potential in this still very young but already mature manufacturing process. The use of continuous technology is an excellent opportunity for plastics manufactorers to generate a competitive advantage and differentiate themselves by offering unique features in the difficult market of environment.

EXJECTION Molding comes into its own

EXJECTION Molding comes into its own

Presented first to the public by Engel on K´2007 Show in Düsseldorf, EXJECTION technologie now becomes established on the market in various applications. A good reason for SPE to publish the current state of this innovative process realized in different modifications. Especially EXJECTION endless prozess sets a major milestone for next generation injection molding. In SPE blog Jan H. Schut wrote: "So a decade after Exjection was introduced to mold long thin parts out of materials that couldn’t be molded otherwise, it’s now under development for high-volume applications in medical, construction, and packaging. Its advantages today for both individual and continuous parts are efficiency, cost saving, and better part quality."
