Rampf begins close contour casting production in Nantong

Rampf Group has officially launched Close Contour Casting production at its Nantong, China site. Raku Tool Close Contour Castings are semi-finished polyurethane systems, supplied as three-dimensional preforms that are near the final shape of the produced part. The manufacturing process begins with a lightweight mold – crafted from EPS or Rampf’s Raku Tool SB-0080 polyurethane styling board – based on data provided by the customer. After applying a release agent, the mold is filled using a specialized casting process. Post-curing and removal from the mold are followed by quick and easy milling.

The company says key benefits of its Close Contour Casting technology include faster machining with reduced tool wear and material waste thanks to close-contour shape; minimal manual finishing due to a seamless, smooth, and dense surface (density 0.8 g/cm3); no handling of liquid chemicals – full focus on milling technology; excellent dimensional stability with low internal stress and isotropic properties comparable to board material; and consistently high-quality standards for reliable performance.

Raku Tool Close Contour Casting systems are used to manufacture high-performance master models, cubing models, and data control models, amongst others.

Based on customer CAD data, Rampf China produces the casting mold and carries out the casting process with targeted heat treatment and quality control. Post-curing ensures high mechani-cal properties. The ready-to-mill casting is delivered to the customer, enabling them to focus entirely on milling.

Tiger Meng, CEO of Rampf China, said: “Our local Close Contour manufacturing infrastructure cuts shipping times, reduces import costs, and enables faster market responsiveness. Most major global OEMs host design centers in Nantong, allowing them to directly benefit from Rampf’s cutting-edge technology.

“What matters greatly to us and our customers: Raku Tool Close Contour Casting actively supports sustainability goals by reducing energy consumption and minimizing production waste.”

Denny Föhn, director, Business Center Tooling & Modeling at Germany-based Rampf Advanced Polymers, said: “Customized blocks and advanced shell-casting structures enable faster, more cost-efficient solutions while ensuring superior product quality. We are excited that customers in China can now also leverage the benefits of Rampf’s pioneering Close Contour Casting technology.”
