Starting with the systematic design of manufacturing processes and the precise simulation of part manufacture, through smart tooling technology and sophisticated melt guidance, to efficient mold temperature control, numerous exhibitors have many innovations in the field of tooling technology on offer at K 2019.The current debates concerning marine pollution as well as anthropogenic climate change and its consequences seem to be having an effect at this world-leading trade show for plastics processing in Düsseldorf, Germany. A number of companies are noting the growing customer interest in sustainable, carbon-neutral and resource-efficient modes of production, and offering products and services intended to satisfy this interest.

Long Live the Standard

At the K 2022, Strack Norma showed its new products for injection molding and die casting, as well as its extensive range of innovative and standardized solutions for tool & mold making. T

Higher Efficiency in Mold Making

Single Temperiertechnik GmbH, Hochdorf, Germany, and Sauer Product, Dieburg, Germany, are now marketing a variotherm mold temperature control system under the brand name Alternating Temperature Technology (ATT). ATT which was presented for the first time at K2007 is a complete system for the variotherm fluid temperature control of injection and compression molds using cooling channels arranged near the mold surface. It contains an alternating temperature control unit as well as a specific arrangement of mold inserts and elements. 

Alternating Temperature Technology (ATT) 

System Solution for High Mold Quality 

If the cooling time in injection molding is overly long, it is often because difficult to reach hot zones, so called hot spots, cannot be efficiently cooled with a conventional mold cooling system. A new system from Stemke Kunststofftechnik GmbH, Döbeln, Germany, that is based on the same function principle as a fridge addresses exactly this area. A coolant circulates in a closed circuit between the injection mold and the refrigerating unit. The circulation of the coolant and therefore the mold cooling is controlled via a thermocouple. 

Closed Circuit Hot Spot Cooling 

Miniaturized high performance cooling 

Mold temperature is one of the most important injection molding parameters since it decisively influences the cycle time as well as the dimensional tolerance. The new cooling elements with their novel connecting mechanism from Wema GmbH, Lüdenscheid, Germany, are a cost effective solution for constructing a high performance cooling system. These make conventional thread cutting a thing of the past. The holes for the temperature control connections are simple and quick to prepare using standardized tooling. Regardless of whether it is a quick coupling, elements for core cooling, diverter and closure plugs, all the connections are made using the same technique. Unlike all the previous systems on the market the new one does not require connecting nipples. Particularly advantageous for the plastics processor is the fact that the protruding nipples cannot be damaged or broken off during transport and storage. Cost benefits result from the elimination of these components and the operations required to install them. 

Easy Connection 

Temperature Control Technology 

By using variotherm mold temperature control, processors are able to meet today’s demanding requirements for surface quality and injection molded part accuracy. Temperature control circuits operating in parallel, increase not only product quality, but also process efficiency. Implementation of such a concept requires accurate control technology and short response times.

Control Technology: Retrofitting Molded Part Quality 

Injection molding with controlled variation of the mold temperature has been promoted as a solution to surface quality and structuring problems in recent years. The article gives an overview of the various techniques and application fields for variable mold temperature control, and, drawing on a non-representative survey of thirty plastics processing companies, shows how far the different processes have made inroads into industrial practice. 

Process Options: The Possibilities and Limitations of Variable Mold Temperature Control 

30 years of trailblazing technologies was the motto adopted by Remak, manufacturer of robots and temperature control units, to celebrate its jubilee. In the last few years the company, previously known as a manufacturer of standardized linear robots, has turned itself into an automation specialist supplying complete solutions. The company substantiated its claim by means of an open day held in the middle of March.

Energy saving has meanwhile become an issue that is considered also in regard to the peripherals of production machines. Increasingly, plastics processors call for holistic approaches that comprise the entire range of process technology and plant engineering.

Energy Consumption: Efficient Tempering and Economic Cooling 

The thermal design of movable cores in injection molds is hampered by the restricted available space and the additional parting lines. Therefore, the IKV has compared different cooling concepts for sliding cores and made recommendations for their design. The thermal boundary conditions of the movable installation position are supported with measurement data for use in injection molding simulation. 

Design of Sliding Cores: Temperature Control Systems in Motion 

Producing high-quality injection moldings not only reproducibly but also on a cost-efficient basis requires precise knowledge of the processes involved. Of particular importance here are the thermal processes that take place in the mold. Anyone who does not bear this in mind will have to pay a high price for ignoring it. 

Heating/Cooling: Cost Factor Corrosion 

The search for a pragmatic approach to cyclic heating and cooling of injection molds has yielded a ready-to-install mold insert that incorporates both high-performance heating and effective cooling. This newly developed heating and cooling element thus integrates two existing partial solutions and has already demonstrated its effectiveness in a trial mold. 

Temperature Control: Hot and Cold Molds 

A new variothermal process for the temperature control of injection molds makes use of laser radiation. Heating in the mold is performed using transparent mold inserts. The laser variothermal technique allows heating rates of up to 300 K/s. 

Functional Surfaces: Variothermal Temperature Control with Laser Radiation 

Raytek GmbH, Berlin, Germany, has launched a new generation of pyrometers. The infrared (IR) sensors of the Raytek MI3 Series consist of a miniature measuring head and separate communication electronics with the sensor head also functioning as an independent pyrometer. With a length of 28 mm and a diameter of 14 mm, the sensor is – according to the manufacturer – the world’s smallest fully functional infrared pyrometer.

The innovative Hasco multicoupling system allows the central connection of several cooling circuits in a single step. 

The innovative Hasco multicoupling system allows the central connection of several cooling circuits in a single step and offers numerous process optimization advantages, according to the company. 

The innovative Hasco multicoupling system allows the central connection of several cooling circuits in a single step and offers numerous process optimization advantages, according to the company. As a result, setting-up procedures can be carried out quickly and easily by hand. Through the defined allocation, there is no risk here of mixing-up the different cooling circuits and hoses.

The largely extended standard system is available as an open or a closed system with valve. The clean break system with flat sealing front surfaces reliably prevents the leakage of cooling fluid when decoupling.

The modular structure allows individual configurations as well as simple integration into existing systems. 6, 12 and 20-fold systems are available, whereby the couplings can be replaced without dismantling the hoses. The multicoupling system is available with a large number of different shut-off couplings and shut-off nipples. These include versions with inner or outer thread, Push-Lok or hose nipples, which further round off the extensive range
