LWB Steinl at K 2019

LWB Steinl at K 2019.

Steinl Group: New LWB vertical machines, Automation, Adhesive and Sealing Technology, but also Biopolymer Applications.

Our company has emerged to a broad-based group of eight companies within the last eight years. Five of the eight companies will give a comprehensive overview of their expertise at K-2019 on our joint stand in Hall 14 / A68. Beyond elastomer injection molding and rubber processing technology, these include, in particular, the adhesive and sealing technology, but also the development and application of fiber-reinforced biopolymers.

 

 


Vertical elastomer injection molding machines with leading ergonomic levels


We will introduce a machine system featuring a vertical rotary table clamping unit, characterized by top marks in operating and maintenance ergonomics. Its central component is a stand-alone, therefore universally accessible, 3-pillar clamping unit with a horizontal plasticizing and injection unit, which centrally injects via a diverter through the upper machine plate. The horizontal plasticizing and injection unit keeps the overall height of the production cell low, which is an operational advantage in halls with low clear height. Due to this concept and the low round table clamping area of just 1000 mm above the floor, the new machine concept offers ergonomic advantages, in particular for injection molding tasks with a high proportion of manipulation, e.g. for the addition of rubber profile frames to car glass panes. The machine drive module including hydraulics is a stand-alone unit as well and thus accessible from all four sides for maintenance and set-up jobs.

Production cell with three-column clamping unit and injection via a horizontal plasticizing and injection unit from above, based on the VSRS 2500/1000 machine type.

 

The second example from the vertical machine program is a C-frame machine with a clamping force of 1000 kN and 1000 cc EFE-injection unit.

In combination with a 2-cavity cold runner tool integrating a new cold-runner-system from ITS-Huber, which is capable for an operation without pressure sensors in the mold cavity the production of rubber doorstops will be demonstrated.

 



LWB Automation: Automated elastomer parts handling and post-processing

The automation potential is demonstrated with a two-machine production cell consisting of a top-closing C-frame-machine in thermoplastic version, type VCRS 500/115 and a portal-frame-machine, type VRF 1100/160. Assisted by a 6-axis robot, they are molding a 2-component shaft seal consisting of a polyamide ring part and a molded-on EPDM rubber seal. Between the two molding steps, a plasma treatment station ensures optimum cleaning and activation of the polyamide surface. The sealing lip is then mechanically post-processed and checked for dimensional accuracy within the production cell.

Interlinked production cell, in which a VCRS 500/115 C-frame machine with thermoplastic injection unit is cooperating with a VRF 1100/160 gantry frame rubber injection molding machine.
The two vertical machines are combined by a handling and processing periphery by LWB automation to a fully automatic production cell for postprocessing of 2-component shaft seals.
The parts will be picked-up by a robot which places the parts into a trimming machine for deburring.
2-component shaft-seal consisting of an outer ring made of a glass fibre filled PA 612 and an inner ring of EPDM-rubber.

LWB biomaterials expertise since 2011

 

Biofibre GmbH, founded by LWB-Steinl in 2011 and based in Altdorf / Landshut, develops, produces and sells natural fiber-reinforced bioplastics for thermoplastic processing into molded articles, with a focus on injection molding. The bioplastics produced are characterized by high eco-efficiency. It results from the production without fossil fuels and the high proportion of recycled plastics. The material development is carried out in close cooperation with the Technical University of Munich. The alliance with Naftex GmbH in Lower Saxony, which was acquired in 2019, ensures compounding in industrial quantities.

 


 

Leading rubber compound batch-off cooling units by Prodicon / Milano

 

The Italian company Prodicon International Slr. / Milano is the fifth company of the Steinl Group on display. Prodicon is a technology leader in the development and production of batch-off cooling lines and special machinery for the rubber compounding in the tire industry, as well as in the field of "technical rubber products".

 


The Steinl Group of eight companies: Five of them will jointly present their competencies at the K-2019 in Hall 14 / A68.
