DENN Spare parts & components
DENN is the machinery brand of Industrias Puigjaner in Spain. It develops equipment for rotational metal forming, including spinning, shear forming and forming tubular preforms. NTR and RL identify different process families. Material condition, starting geometry and the required wall-thickness distribution therefore matter in a technical enquiry as much as the machine designation.
Send the nameplate, configuration and quantity. Availability, price and lead time are checked for your enquiry.

RL
Product family · specify the variant
Cylindrical flow-forming family for tubes and preforms using three rollers positioned at 120°.
Send an enquiry ↗Technical selection
State machine type, serial number and CNC generation. Document material and heat-treatment condition, starting diameter, wall thickness and preform length. The drawing should distinguish target contour, permitted thickness reduction and tolerances. For rollers and mandrels provide profile, mounting, material and drawing number. Describe clamping, tailstock and additional heating or cooling functions. Process programs may depend on machine, tool and material batch. Identify replacements from the assembly list rather than selecting solely by the finished part. Changes to tooling geometry or process sequence require technical assessment and, where appropriate, an agreed forming trial.
