Injection Moulding

  • Elmet at K: New developments and enhancements in LSR dosing

     

    Elmet at K: New developments and enhancements in LSR dosing

      polymer & packaging news agency - www.ppna.ir

    Elmet is presenting itself at K2019 as an international one-stop shop supplier for the entire field of injection moulding two-component liquid silicone rubbers (LSR).

    One focus of Elmet’s exhibition will be its enhanced TOP 5000 P pneumatically driven dosing system, which has a smaller footprint than its predecessor. Elmet will also provide an initial glimpse of the status of development of a servo-electrically driven dosing pump and premiere its new remote maintenance system for the TOP 5000 series.

    Elmet is preparing for the commercial introduction of a TOP dosing system with a fully electric dosing pump driven by a torque- and current-controlled servomotor. Here the focus is on minimising dosing fluctuations and maximising efficiency and simplicity of operation.

    Despite occupying still less space in the production zone, the upcoming designs of the TOP-5000 dosing systems do not entail any compromises in terms of efficiency.

    Sales Manager Mark Ostermann said: "Our electrically driven dosing system will be the result of very extensive development work, the first step of which focused on designing the pump group. Initial testing of the newly developed components of the pump group has demonstrated the uniform quality of delivery which is achievable using this new principle … Once the system is ready for mass production, we will be able to offer a suitable solution for all market segments and applications up to and including LSR 3D printing. Elmet will thus be in a position to meet any possible future customer wishes."

    In terms of Industry 4.0 capability, all TOP 5000 series dosing systems have a VNC and an OPC-UA interface for data exchange with the injection moulding machine. The newly created remote access interface means that Elmet will be able to offer a Premium Connectivity Package with email functionality and remote support. The software can automatically send email messages to predefined groups of recipients in the event of a breakdown or maintenance and drum change messages.

    A VNC link means that Elmet and operators can remotely access the relevant dosing system from anywhere in the world without requiring access to the customer's own IT network.

  • Jomar launching TechnoDrive 65 PET at K

     

    Jomar launching TechnoDrive 65 PET at K

    Jomar Corp., a leading global manufacturer of injection blow moulding (IBM) machinery for the pharmaceutical, healthcare and household products industries, will launch the TechnoDrive 65 PET machine at the 2019 K Show in Düsseldorf, Germany.

    Specifically designed to run PET resins but can easily switch back to PP and PE, the TechnoDrive 65 PET machine evolved from Jomar’s TechnoDrive 65, a high-speed production machine unveiled in 2018. It has a dry cycle time of just 1.7 seconds, making it one of the fastest injection blow moulding machines in the industry.

    Jomar’s engineers have expanded the TechnoDrive 65’s capabilities by adding a more robust plastifier motor, high-pressure valves and built-in nozzle heaters to aid PET processing.

    Jomar President Carlos Castro said: “The TechnoDrive 65 PET further demonstrates the versatility of the Jomar machines. Jomar machines can handle engineering resins and a wide range of PET grades such as PETE or PETG. We’re giving our customers the opportunity to bid for a variety of projects from cosmetic jars in PET to packers in HDPE, with the same machine.”

    The TechnoDrive 65 PET can mould a variety of shapes and sizes in PET. One limitation, however, is rooted in the nature of injection blow moulding. Unlike injection stretch blow machines, an IBM machine does not mechanically extend its core rods, which provides biaxial orientation and allows for extremely thin walls such as those found in water or soda bottles.

    The average wall thickness for a TechnoDrive 65 PET bottle in PET is 1mm, so it is more inclined to mould jars, vials and bottles for the pharmaceutical or cosmetic industries.

    All PET projects for the TechnoDrive 65 PET would be accepted as a turnkey project where Jomar is building both the machine and mould. This allows Jomar to tailor the equipment to provide the largest processing window and ensure the project’s overall success.

  • K 2019: Sepro and partners to demonstrate automation solutions

  • KraussMaffei exhibits closed material and manufacturing circuit at K 2019

     

      polymer & packaging news agency - www.ppna.ir

    KraussMaffei will continue its technological pioneering in the preparation and reuse of recycled plastics at this year's k trade fair .

    Packaging products fulfil their purposes quickly, so KraussMaffei has asked why can they not be used as raw materials for new high-tech articles in the automotive industry? At K 2019, the company will be demonstrating how a bucket can become a premium panel of an A-pillar with an overmoulded fabric surface. A ZE 28 BluePower twin-screw extruder makes this possible by upcycling the material.

    KraussMaffei exhibits closed material and manufacturing circuit at K 2019

    Under the keyword of the circular economy, KraussMaffei is linking its extrusion, injection moulding machinery and digital and service solutions business units at the trade fair.

    KraussMaffei as an enabler

    Edelweiss Compounding is intended to make on-site compounding more attractive to recycling companies and plastics manufacturers. Matthias Sieverding, President of the Extrusion Technology Segment at KraussMaffei, said: "We view ourselves as enablers of the circular economy for our customers so that they can be successful as part of this economy. KraussMaffei is aware of its responsibility and, as one of the world market leaders, wants to occupy a leading role in the areas of recycling, upcycling and recompounding of plastics."

    Both in extrusion and injection moulding, the third participating KraussMaffei business unit at the K trade show, Digital Service & Solutions, will be showcasing products such as APC Plus (Adaptive Process Control) and DataXplorer.

    APC Plus monitors the injection moulding process and adapts it to balance interference factors such as fluctuations between batches and in climate. In injection moulding, this is done via the internal material database and the online analysis of the melt viscosity, as well as by adjusting the holding pressure changeover point and level, even within the same cycle. In extrusion, the melt temperature, pressure and screw speed are recorded. 

    The DataXplorer makes a detailed view of the depth of the process possible because it is capable of storing up to 500 signals every five milliseconds. 

    All data resulting from this is routed to the new data system, which is being introduced at K 2019.

    Digital services help ensure the quality of production and products, prevent rejects, and thus also contribute to resource-conserving production. 

     KraussMaffei is enhancing its joint effort with partners and customers to develop new business units regarding the reuse of plastics.

     

     

  • SIGMA presenting SIGMAinterac at K 2019

     

     

    SIGMA presenting SIGMAinterac at K 2019

      polymer & packaging news agency - www.ppna.ir

    At this year’s K Show SIGMA Engineering will align its booth concept with the motto ‘SIGMAinteract – Autonomous Optimization connects departments’ and present its new SIGMAinteract.

    In a co-operation project, SIGMA will show how to use virtual DoE during the entire development process. With SIGMAinteract, results are displayed interactively and in 3D. Thus, its usage makes knowledge tangible and easy to share.

    At the SIGMA booth in Hall 13, Booth B31, this immediately becomes visible with a completely new design concept.

    Making informed decisions throughout a project requires involvement from partners in various departments. This means project data must be provided to each participant and they will need free and easy access to it. Therefore, SIGMA presents its new SIGMAinteract so that users can share SIGMASOFT results interactively and in 3D.

    Visitors can experience and use SIGMAinteract live at the booth, where SIGMA will demonstrate how virtual DoE is used most efficiently and how the SIGMAinteract tool significantly contributes to a good interdisciplinary exchange. As a demonstration, SIGMA uses the project ‘Pot Cloth’, which was realised as a collaborative project with Momentive Performance Materials GmbH, Germany, EMDE MouldTec GmbH, Germany, Wittmann Battenfeld GmbH, Austria, and Nexus Elastomer Systems GmbH, Austria.

    In this project part design and tool construction were done in parallel. Therefore, it was necessary for all partners to work closely together. Simultaneously, SIGMA conducted a virtual DoE for the validation of the part design and the evaluation of the heating concept.

    At the SIGMA booth visitors can also virtually observe the production of the ‘Pot Cloth’ live. It will be produced on a SmartPower 90/350, control UNILOG B8, from Wittmann Battenfeld. The LSR injection moulding tool, including the cold runner system, was constructed by EMDE MouldTec. The system is completed by a ServoMix X200 dosing system from Nexus Elastomer Systems. Silopren LSR 2640 from Momentive Performance Materials is used as material for the production.

  • Wilmington Machinery delivers engineering breakthroughs and increased moulding capacities

     

    polymer & packaging news agency - www.ppna.ir

    Wilmington Machinery has built and installed two vertical structural foam presses for a customer looking for a machine more suitable than a horizontal press, but with all the advantages vertical presses provide.

    The two new large vertical type low-pressure structural foam presses accept between one and six moulds mounted and can produce one to 20 components per cycle. Each vertical press mould is filled independently and precisely by Wilmington’s proprietary Versafil injection system.  

    To meet customer demands, Wilmington re-engineered the MP800 injection unit to incorporate a first-in, first-out, reciprocating screw of 30:1 L/O and an in-line accumulator arrangement. The design maintains the ability to compound both virgin and recycled resins with various fibrous and non-fibrous additives for strength and reducing the cost of the moulded component. 

    Direct gas injection into the extruder barrel provides large part thin-wall structural foam moulding. The machine is also capable of non-foamed moulding of medium-sized parts. 

    The MP800 model retains its capability of both cold and hot runner moulds using either short shot (foam) or pack/hold moulding techniques. 

    A second complete Wilmington Machinery plastic pallet moulding system has also recently been delivered to a European customer. 

    The US-based company is inviting attendees to its stand (Hall 13, booth B91-19) at this year’s K trade fair in Düsseldorf, Germany.
