With a broad spectrum of infinite color variations, GRAFE, Blankenhain, is bringing variety to the market for 3D printing applications and presenting this to its customers with a box. This contains ten basic colors, of which a white polymer blend acts as a carrier. “The silk effect or gloss only really becomes visible in 3D printing,” explains Lars Schulze, Head of Color Development and Material Sciences. “With the colors, we offer a tested base, the so-called silk effect with corresponding good printability and high gloss level.” The project was specifically developed to reproduce this noble gloss effect. Certain pigments’ selection avoids matting, leading to the highest gloss level. Two color combinations in a shapely vase look provide a preview for design inspiration. The two color models are presented in a high-quality box. A color table with 19 mixing examples is intended to serve as a stimulus among the infinite color combination possibilities and to represent the most diverse demands of users. It serves as an orientation and should make it possible to meet customer requirements quickly. In addition, the customer receives corresponding dosing suggestions. However, the presentation samples only provide inspiration for users because there are no limits to color fantasy with the basic colors, and the user can mix his colors creatively and achieve individual color shades. Up to now, there has only been a small choice of colors for high-gloss filaments on the 3D printing market. We want to change that with our expertise in coloring plastics and offer a basis for customization with our masterbatch,” explains Schulze. GRAFE has its own filament extruder and 3D printer in-house and can thus produce and test appropriate filaments itself. “In this way, we are able to try out our own developments. This significantly reduces development times, as the time-consuming testing process at the customer’s premises is no longer necessary,” says Schulze.

What is an IsoForm® tool? IsoForm® tools are holistically designed insulated molding tools with advantages for process reliability, quality and energy efficiency. We offer IsoForm® in the BASIC and PREMIUM versions, which differ in the type of centering and the degree of insulation. Both versions are available in many designs, e.g. with interchangeable insert modules and interchangeable plates, and are always insulated in the contour-forming area. The IsoForm® standard parts program was developed by the Konstruktionsbüro Hein GmbH and is distributed by our partner, Nonnenmann GmbH.

Thin wall thicknesses and tight tolerances

The use of the flexible ISOHeat insulation system prevents heat loss and thus reduces energy costs. Very good results are achieved when insulating heated cylinders in injection molding and extrusion processes. On average, savings of 20-40% can be expected. In addition, the ambient air heats up significantly less. A safer working environment is also created for operators, as the surface temperature is 50-70% lower.

iSONIC ECO TM Ultrasonic power with dual drive option – electric or pneumatic Ultrassonic in perfection The iSONIC ECO TM, electric or pneumatic, masters ultrasonic welding, riveting, embossing, cutting and sealing. Compared to conventional thermal welding processes, the use of ultrasound is characterized by its energy efficiency, as no tool heating is required. However, if the application requires it, thermal or non-contact welding methods can be used. The combination of efficiency and flexibility makes the iSONIC ECO TM the perfect solution for application processes in the automotive, plastics, technical textiles and packaging & food industries. Drive technologies as required Which drive do you prefer? Electric or pneumatic? The iSONIC ECO TM is designed to offer both options. With its slim design and versatility, this tabletop machine remains flexible for your individual application processes. The electric drive demonstrates its outstanding efficiency in movement tasks, while the pneumatic drive shows its strengths in holding times. Various cylinder sizes are available to ensure maximum force.

Insulation covers for the heating zones of plastics processing machines and other applications Reduce energy consumption and thus lower energy costs! Reduce CO2 emissions! Areas of application: ISOWEMA® insulation sleeves can be customized for each heating zone, regardless of the machine type. The electrical connection area and sensor inputs are taken into account. Advantages: - Reduction in machine heating energy consumption by 20 to 40% - Extended heater lifespan by reducing switching cycles - Increased work safety by reducing surface contact temperatures by 60-70% - Prevents the risk of burns - Can be retrofitted at any time - quick installation and removal - Long insulation lifespan thanks to the use of high-temperature, wear-resistant materials - Physiologically safe insulation materials - The payback period for ISOWEMA® insulation is typically less than 1 year - Reduction in heat-up times - Optimization of the indoor climate in production halls - Individual, customer-specific designs - Uniform temperature profile on the machine cylinder - Insulation can be manufactured based on 3D data (STEP/IGES format) On-site measurement possible - Insulation installation by our employees upon request - In conjunction with the ECOWEMA® flap system KSHK can also be used on extruder cylinders

Up to 240 zones on four wheels with maximum operating comfort: Clear touch panel and maximum data compatibility – this “control cabinet” is where it’s at! The JETmaster TP, the floor-mounted device from our systematic TP series, combines all the requirements for optimum process reliability and ease of use in one device. Once connected, all moulds are immediately operational again without the need for a restart. Comfortable: the control via industrial PC with large touch panel. Profitable: Maximum-sized external cooling elements ensure that the device remains maintenance- and wear-free.

The micro device JETmini for 1 to 2 zones is barely the size of a shoe box and yet it is up there with the big ones in terms of quality: Thanks to continuous process monitoring, the temperature controller in a handy stack format ensures reliable processes in your plastics production. JETmini is suitable for general heating applications as well as different types of sensors and stands out due to its particularly simple and intuitive operation. It goes without saying that the mould connections of the JETmini are also manufactured to suit your standard. At no extra cost whatsoever. That’s our service for you.

Recycling 2 Use of recyclate for technical products The joint project Recycling 2 focuses on the use of recyclate from various post-consumer sectors for technical applications. In order to better assess the potential uses of these material flows, the project focuses on the following areas - Characterization of post-consumer recyclates from various sources (e.g. yellow bag, ocean, end-of-life vehicles, e-waste, etc.) - Examination of batch consistency - Testing the long-term behavior - Determination of emissions during processing - Characterization & improvement of the odor (VOCs ) of recyclates through the use of odor absorbers Project start: April 2024 Term: 2 year
