In-house products Dunloflex
Henry Technologies GmbH is a subsidiary of the American Hendricks Holding Company. The products are supplied to well-known manufacturers of agricultural and commercial vehicles and to spare parts dealers. One of our core competences is the development, production and international distribution of wheel covers made of plastic and rubber under the Dunloflex brand.
Another skill is our extensive expertise and our capacities in injection molding and rotation molding of thermoplastics for contract manufacturing, with our experience and machine capacities for the injection molding of large-volume parts worth highlighting.
Slogan: “The specialist in rotational sintering. With extensive experience in plastics processing, we manufacture in rotational molding complex plastic hollow bodies in any shape and size to meet your individual requirements. You can leave the production of your plastic parts to us and profit from our many years of experience."
History:
The history of Henry Technologies GmbH goes back to the beginning of the 70s. 2015 saw the installation of the new 3-arm rotational system, with a 3.50 m carousel machine. The extension of the existing machinery providing rotation and injection molding, leads to even greater performance and efficiency.
2018 saw the installation of the second rotational system, a 4.7 m long carousel machine with 2 straight arms and 1 L-shaped arm.
Rotational sintering is a rotational process in which the plastic is processed without pressure. The term rotational molding is also often used.
In rotational sintering, we use plastic powder that has thermoplastic properties. Powder material is filled into the hollow body mold, then the rotating arm and rotary plate set the mold into a slow rotational movement. The rotational mold filled with powder material is moved biaxially at temperatures of 230° C to 300° C in the smelting furnace chamber.
Under controlled heating, the raw material fuses slowly, sticks increasingly to the inner wall of the mold and builds up the wall thickness of the plastic part layer by layer. Fans then circulate cool air around the plastic parts still in the mold. During the cooling phase, rotation continues so that the plastic retains the desired shape as it solidifies. After controlled cooling, the finished plastic part is then removed. We use this process to produce not only our own product range under our own brand Dunloflex, but also items to customer order, such as covers, tanks, panelling, interior and exterior parts.
