LWB-Steinl at the K 2016

New machine control, new ergonomically optimized vertical machines and a processing competition

At the K-show the German injection molding machine manufacturer LWB-Steinl introduces, as main innovation, the new FlexEvo machine control, which sets new standards in operating logic and process precision. The most important technical innovation is the "Performance" line of vertical machines. Last but not least LWB-Steinl demonstrates their wide scope of rubber molding technology through producing the same molding with to two equal-sized machines but with different equipment levels at different cycle times.

New FlexEvo Machine Control

After being launched at the K-2016, the completely new FlexEvo operating and

programming system will be available for all LWB-injection molding machines. It was

developed in collaboration with the Austrian electronics company Bernecker & Rainer and

uses their "MAPP“-concept (Modular Application concept), which is basically known from

mobile phones. The predefined basic program modules cover specific process objects and

can easily be adapted to the actual operation by setting individual values, either by

changing a function curve via finger touch or entering a numerical value. An organizational

app, called „Code Box“, automatically links the individual program modules to a machine

cycle. Individualized cycle sequences can be created via a graphical sequence editor. The

module library contains also special sequences as pre-defined, but individually

parameterized, sub-programs, such as the mold monitoring system with up to 8 sensor

inputs. Beyond the motion modules also process modules are available, e.g. for the

measuring and optimizing of the energy consumption. The user interface of the FlexEvo

control is a 18.5 inch multi-touch display (Fig.1). It can be operated both directly by touch

(even with gloves), as well as through gestures and swipe movements. But not only the

LWB-Steinl at the K-2016 -


operational comfort had been increased, but also the overall precision. It is the benefit of

the new hardware that enables a shorter signal scan-rate from 2 ms (0.002 sec) to 400

microseconds (0.0004 sec), which significantly increases the process accuracy (for

example, during the injection process). An additional highlight of the new LWB-control

system is its universality and flexibility. Thus, the machine control is configurable without

time-consuming adaptations for all machine types, even for special purpose machines.

One more important advantage of the modular control concept is the integrated option for

the connection to a higher-level production control such as Industrial 4.0. For that LWB-

Steinl cooperates with the MES (Manufacturing Execution System) specialists T.I.G. Their

software solution "authentig" will be demonstrated at the booth too.

Vertical machines with "Performance"-clamping units

Following the trend of the steady increase of complexity of injection- and compression-

molds LWB-Steinl has increased the installation space in the clamping units of their vertical

machines both with C-frame- and tie-bar clamping units and introduced the new machine

line with the version label "Performance". The characteristic feature of the vertical tie-bar-

machines is their innovative clamping system. Its highlight is the low working height, not

requiring a recessed installation in a pit. The "Performance" machines with 4-tie-bar-

clamping-unit are available in the clamp-force range from 160 to 800 tons. Two 300 t

„Performance“-machines with different equipment will be demonstrated in operation (Fig.2)

at the LWB-booth.

Similarly, the C-frame machines had been revised too, which are available in top-closing

version up to 160 tons and upwards-closing up to 250 t clamping force. As a representative

example, a top-closing C-Class „Performance“-machine will be on display.

Demonstration of the EFE-potential for the reduction of curing time

The EFE-injection system, developed by LWB-Steinl, represents the process technology

highlight of the K-show-presentation. It converts, during injection, kinetic energy through

controlled generated shear into additional heat energy in the rubber compound. The thus

generated temperature increase initializes the vulcanization process faster. That allows for

curing time reductions in the range of 30 to 50 percent without compromising on product

quality in most rubber compounds. In order to demonstrate the efficiency-potential of the

EFE-system, LWB-Steinl demonstrates two 300 ton vertical machines of the latest



"Performance" type with different equipment levels in a performance competition. Machine

One is equipped with an EFE-injection unit in combination with a valve-gate cold runner and

a machine drive by a dual-servo motor system, while the second machine represents a

standard execution with an EFD-injection system in combination with an open cold

runnersystem and a drive system with a proportional hydraulics. For comparision both

machines will produce the identical rubber part. To put the result first: The differences in

productivity are impressive.

Vertical C-frame micro-injection molding machine

The LWB-machine presentation is rounded off by the smallest vertical machine. It is a micro-

injection molding machine with 10 tons C-frame clamping unit and 10 cc injection volume.

The repeatability for the injection weight is ± 0.005 grams (Figure 3). Since the clamping unit

design is based on the tiebarless C-Series machines, the micro machine offers likewise

optimum conditions for the addition of automation equipment. The highlight of these

machines is besides their precision their compact design. The footprint of the vertical micro

machine of only about one square meter integrates not only the machinery itself but also two

temperature controllers.

CAS demonstrates latest version of the process optimization software „Jidoka“

The North German process developer CAS will present at the LWB-stand his process

software Jidoka P 101. It continuously monitors all influences on the quality (batch and

process parameters variations) and indicates concrete proposals for process optimization

with direct reference to the current process and a specified degree of crosslinking in the

rubber part to the machine operator. The software represents the latest status of process

intelligence in the form of control algorithms, steadily evolved over many years. The quality

achieved is documented by the CAS testing device Jidoka S 101 III, which is on-line

interfaced with the molding machine, as a result of a non-destructive quick test of dynamic

and static material properties.

About LWB-Steinl

The company was founded by Alfred Steinl in 1962. Since its beginning the company has focused on tools and machines for rubber processing. Today, the family-run business continues to be one of the worldwide leaders in the manufacturer of rubber injection moulding machines. The product portfolio includes a complete range of rubber injection moulding machines, from vertical C-frame machines specific for profile bonding to vertical 4-column or plate frame machines, through to horizontal machines with columnar and C-frame clamping units. In addition, the product portfolio includes so-called batch-off plants for compound mixing. The company is headquartered in Altdorf bei Landshut in Germany. It currently employs around 230 people and produces about 500 machines per year. In addition to its production location in Germany, it has operated a production plant in China since 2009.
