Our plastic packaging tubes combine functional product protection with attractive product presentation – ideal for delicate, high-quality, or durable items. Whether in retail, industry, or transport: Our tubes offer maximum safety with minimal material usage. Thanks to their high resistance to point and area loads, as well as their durability, they also make a valuable contribution to environmental protection – especially in reusable or long-term use. With suitable closure caps, our packaging tubes can also be used as feeding systems or transport sleeves. In addition to our extensive standard range, we also manufacture customized tube sizes according to customer requirements.

As a long-standing system supplier, we don’t just “roll up our sleeves” when it comes to injection molding. We also take full responsibility for all upstream and downstream value-adding processes, ensuring that you receive your product from a single source – cleanly coordinated, expertly monitored, and reliably executed. A complementary supplier management system ensures that we can involve the right specialists for every specific requirement, without any effort on your part. For surface finishing, we offer a wide range of processes: from pad printing, electroplating, metallization, and flocking to laser marking and coating. This ensures that every component receives exactly the visual and functional properties required for its intended application. We also take responsibility in the area of assembly. Our in-house assembly department produces complex small series, including integrated optical inspections. In addition, products are professionally assembled by our inclusion group on-site or further processed through long-standing cooperation partners as part of an extended workbench. Depending on the requirements, semi-automated workflows or even fully integrated automation solutions can be implemented directly within the injection molding process. The result is a comprehensive package that goes far beyond injection molding alone – a holistic solution that streamlines processes, ensures quality, and significantly reduces workload throughout your product development cycle.

Our plastic tubes and hollow rods impress with their high dimensional accuracy, smooth surfaces, and versatile applications – whether as protective sleeves, packaging tubes, guide systems, or for technical applications. We process rigid PVC and PET as standard, as these materials are characterized by their excellent dimensional stability, processability, and chemical resistance. Upon request, we also use other plastics – depending on your specific application. In addition to our proven standard range, we also manufacture custom dimensions and lengths – precisely tailored to your product.

Our plastic rods – also known as round rods or solid rods – complement our range of semi-finished plastic products with a compact, robust solution for a wide range of applications. Manufactured from proven materials such as rigid PVC and polystyrene, they impress with their dimensional stability, dimensional accuracy, and a consistently smooth surface. The rods are ideal for technical applications, as guide elements, spacers, supports, or for model and fixture construction. We produce to order, so you receive exactly the dimensions, color, and length you need for your product or application.

According to the designers at GRAFE Blankenhain, the "haute couture" of individual color and surface design of plastics consists of adding contrasting fibers or plastic particles to the desired base color. The result is customized surfaces and structures that raise product design possibilities to a new level. In the automotive sector, manufacturers' concept cars demonstrate this new trend. "Bumpers, sills, underride guards or wheel arch liners that appear to be made of stone with their marbled look are all the rage, especially for SUVs," reports Danny Ludwig, Head of Product Management, Color & Functional Masterbatches. "There is a lot of demand from German and French OEMs, specifically for exterior parts." The first components have already been realized with GRAFE's masterbatches at parts suppliers and have met with great approval, Ludwig says. "Flakes and fibers of different structures are incorporated into the batch. What's completely new is that this can now also be realized with automotive-grade PP grades with a high recycled content, thus going some way toward fulfilling the sustainability promise." The main plastics for which the newly developed effects are used are PP for exterior and PC/ABS for interior applications. A 20 to 30 percent recycled content in PP is currently possible while still meeting the high demands placed on plastics regarding durability, emissions, component mechanics, and quality. "For automotive manufacturers, black and gray are the most interesting, but for other industries, many colors are possible." Whether flower pots, furniture, caravans, or toys. The applications are endless, Ludwig says. The development and identification of new raw materials that are suitable as additives are in constant motion within the company.

The combination of plastic and metal is often an alternative for innovative drive solutions. This makes it possible to utilize the advantages of such different materials in direct combination. An appropriate technical design of the combination and the individual parts is essential. Our work therefore often begins with the design of the connecting parts, the design of the tool concept or the selection of the optimum materials. The result is products with properties that are only possible through the combination – developed, optimized and manufactured from a single source.
