Latest Patents:
Among Siebolt Hettinga's recent patents, two notable inventions stand out. The first is the "Plastic Article of Varying Density." This method involves incorporating a blowing agent into a plastic material and injecting it into a specially designed mold cavity. Maintaining a controlled temperature within the cavity prevents the formation of gas bubbles in the outer skin of the plastic article. By employing a reconversion phase, Hettinga achieves the desired density without any surface irregularities or voids. This technique offers an efficient and streamlined process to produce complex, lightweight plastic articles with grooves.
Hettinga's second recent invention is the "Heat Laminated Fabric Hinge." This hinge consists of a fabric hinge member that is securely embedded within the hinge attachment surfaces of two other members through heat lamination. The process involves applying heat to make the hinge attachment surfaces flexible, allowing the fibers of the fabric hinge member to embed within them. By utilizing this method, Hettinga creates a durable and robust fabric hinge that can easily withstand repeated use.
