Unforeseen downtimes in serial production are always accompanied by high costs, making it essential for machines to be serviced in time. Because sensor, transmission and data storage technology have taken a big leap forward in recent years, predictive maintenance has already been realized in some industries, demonstrating a tangible benefit of Industry 4.0. The WZL and the WBA have developed a guideline for this.

iQ motion control from Engel now allows reliable early start combined with fully automatically optimized motion planning. The assistance system has been part of the standard kit of all new Engel viper-type linear robots since October 2021.

If the robot travels into the mold area already during the mold opening movement, this can shorten the cycle time. The effect is particularly large in the case of parts with long cores, such as boxes

Engel’s new “Parameter Limits” feature provides a remedy. It supports injection molders in keeping the parameters constant within a process window.

With the new Parameter Limits feature, tolerance ranges for up to 150 process parameters can be fixed directly in the machine control system for up to 150 process parameters. A change of the selected setpoint values is then only possible within the defined process window.

Keeping Setting Parameters  under Control

In the production of plastic parts for the medical and pharmaceutical industry, the requirements for cleanroom environments are becoming increasingly stringent. In this area, not only the demand for all-electric injection molding machines is increasing. There is also an increasing use of electric drives for the implementation of mold movements, which meet the high requirements for cleanliness and reliability.

Miniaturization is a Megatrend

Pharmaceutical crimp caps generally consist of a thin aluminum sheet and a plastic component, and are used to seal medical vials, for example for vaccines. Through a combined deep-drawing and backmolding process with previous inline laser treatment of the thin aluminum sheet, the process can be significantly shortened. The media-proof joining together of the two materials is carried out through a mechanically interlocking connection.

Harsh Realities

The Arburg Host Computer System as a Basis of Higher Productivity and Product Quality

How do you bring 65 injection molding machines and various assembly lines – most of the manufacturing cells in the cleanroom – as well as, soon, a large number of ancillary equipment under one digital roof? A field report.

How do you bring 65 injection molding machines and various assembly lines – most of the manufacturing cells in the cleanroom – as well as, soon, a large number of ancillary equipment under one digital roof? A field report about the highly complex project for introducing a host computer system, which was performed in a very grounded way and has helped Röchling Medical boost its performance on several levels.

We are one of the few customers in medical technology who use the ALS host computer system.” Daniel Tobin, Head of Production at Röchling Medical Waldachtal AG establishes the benchmark at the very beginning of the discussion, which Kunststoffe holds with him via a video link. When, in the course of the following hour, we hear from him that they have succeeded in not only increasing the company’s own plastics processing productivity, but also patient safety, this finding may seem astonishing at first.

ALS is the German abbreviation for the Arburg host computer system, the production management tool of the injection molding machine manufacturer from the Black Forest, Germany, which, with its modular design, can be adapted to the manufacturing plant’s needs and can grow along with the production size and its requirements. ALS can be used to manage the entire production – to achieve a high product quality and as little machine downtime as possible. Indicators that are available at all times, about current orders, processes or the overall production effectiveness put users in a position to identify weaknesses and achieve lasting improvements in processes and work flows.

High Requirements, Strict Documentation Obligations

The medical branch, with sales of EUR 164 million, is the smallest of the Röchling Group’s three divisions, whose overall revenue, with the two strong pillars of automotive and industrial, was just over EUR 2 billion in 2020. Medical products are produced at a total of six sites in Germany, the USA and China. In 2018, the site in Waldachtal, Germany, was added, which Röchling took over from Frank plastic AG and where Daniel Tobien coordinated all phases of the ALS roll-out.

It is well known that the requirements and documentation obligations for manufacturing medical products are particularly high and strict. Why that is – or better said, must be – the case becomes immediately clear if we look at Röchling Medical’s product range. The company acts predominantly in three market segments (medical technology, diagnostics and pharmaceuticals), the arc stretches from crystal-clear parts for oxygenators, which filter and oxygenate the patient’s blood outside the body during heart operations, through Petri dishes for diagnostics, as well as different pharmaceutical primary packaging and administration systems, to ophthalmological instruments for eye surgery or endoscopic solutions for minimally invasive surgery.

“Some 85 percent of the parts that we manufacture in Waldachtal are highly complex applications,” says Tobien. This requires a precision that is often not apparent at first sight, if at all. The trained mechanical engineer refers to geometrical and dimensional requirements on one hand and dimensional requirements, for example in 0.2 mm diameter needle guides or in blood-carrying components, which must be flash-free with their edges and orifices rounded, so as not to damage the blood corpuscles as they pass through. On the other hand, he mentions the high optical requirements: “How are doctors and nurses expected to distinguish whether the black specks in crystal-clear parts are uncritical inclusions in the material or loose foreign matter? “In addition, the proportion of assemblies and ready-assembled, packaged and sterilized single-use products has been growing for years.

Cleanroom with 43 Injection  Molding Machines

The Waldachtal site has resources such as product development, an own mold making shop (including design), an automation department, as well as product validation specialists, and mainly produces in a 2500 m2, class ISO 8 cleanroom. It contains 43 injection-molding machines, 22 are outside the cleanroom and are partly equipped with laminar flow boxes – these machines are to be primarily connected to the ALS.

The machines process all conventional thermoplastics, including high-performance polymers such as PEEK or PEI with shot weights from 0.1 to 1800 g and processes such as insert and multicomponent technology, micro and endless injection molding. “In the cleanroom, we produce quantities from 10,000 to 24 million units per year, from customized components and assemblies to complete OEM products,” says Tobien. One of the best sellers is a Luer Lock cone for prefilled syringes with injection port. All injection-molding machines are connected to a computer-aided, fully automated pellet drying and feed system.

When you realize that production also includes ten assembly units and four assembly lines, which are also to be connected to the ALS without exception, and such different processes as laser marking, pad and screen printing, hot embossing and various welding techniques, such as ultrasonic welding, you get at least an idea of the complexity of the project. But the question remains, why use a host computer system at all?

Of course, Röchling Medical has thought carefully about the answer, “We essentially wanted to increase the transparency in production. Likewise, we wanted to perform better process analyses and make our problems, which we knew more by feeling in the past, visible and to gain an understanding of them. The crucial point was that we wanted to control production with a KPI and needed a tool for this in order to introduce the OEE as an indicator and represent it rationally,” explains Tobien in retrospect.

The overall equipment effectiveness (OEE) is defined as the product of the factors availability, performance and quality. In principle, it is an indicator for unplanned losses of a plant due to shutdown or producing rejects. The OEE thus indicates for how much of the planned running time a machine has actually generated products corresponding to the quality criteria. Based on the mathematical formula, the value generally lies well below 100 percent, with the limiting factors revealing the weaknesses.
