About elastoform
elastoform Gesellschaft für technische Formteile mbH, based in Hambühren, has been developing and manufacturing custom technical molded parts made of polyurethane (PUR) since 1983. In a complete in-house process, components are handled from technical consulting through design and in-house toolmaking to production, assembly and 100 percent visual and functional inspection. Production takes place using cold and hot casting processes on seven high-pressure machines and one low-pressure machine; in addition, 4-axis CNC milling machines, CNC and conventional lathes, 3D printing and laser systems are available for prototyping and reworking. Products manufactured include thread protectors to API standards, wear parts and design parts, PUR-coated rollers and drums, conveyor screws, pump housings and brush bodies – also as metal replacements in small and medium series. Customers come from the oil and gas industry, agricultural machinery, conveying technology, pump, well and special machinery construction, the concrete and brush industries, and ordnance clearance. The company has production, warehouse and reworking halls covering more than 2,900 m², is certified to ISO 9001:2015 and has been part of the ACO Group since 2023.

Materials and Processes
Polyurethane (PUR)
Elastic, dimensionally stable material with variable Shore hardness for technical components from soft to high-strength.
Synthetik Ultra
Proprietary PUR system for highly stressed, abrasion-resistant molded parts such as conveyor screws and connector feet.
Cold Casting Process
Cost-effective production of thick-walled PUR molded parts, among other things as a replacement for rubber and Vulkollan coatings.
Hot Casting Process
Process for durable, highly stressed molded parts such as conveyor screws with large wall thicknesses.
PUR Coating
Coating of steel and cast steel rollers, drums and bearings with wear-resistant polyurethane.
Steel/Cast Steel
Base material for coated rollers, drums and bearings in conveying technology.
