FLOW FORMING

RL

DENN has completed the assembly and verification of a new unit of the heavy duty 3-roller Flowforming machine model RL-140/435 prior to the delivery and installation overseas.

SHARE FORMING

NTR 60/15

It is designed to manufacture rotational metal parts from discs, tubes, cones, or simple preforms, combining industrial productivity with intuitive graphical programming to speed up setup and improve repeatability.

METAL SPINNING

NTR – 130/50

Since its establishment in 1885, DENN has manufactured metal spinning machinery. Its models have gradually evolved, from the primitive manual lathes to the current machines operated by computer systems.

FLOW FORMING

LW1

It manufactures rotational parts from preforms, combining industrial productivity with graphical programming through DENN Cad-Cam to ensure precision and repeatability.

TRIMMING, BEADING AND FLANGING

RB

The technology used for trimming, beading, and flanging operations, among others, is similar to that of metal spinning, incremental deformation, although much simpler machinery and tools are used.

METAL SPINNING

NTR-250/250 CNC

From the beginning of the company’s foundation, Industrias Puigjaner has designed and manufactured machines to form plate and tube using rotational methods.

SHARE FORMING

LW1 conos

The LW is a vertical single-carriage CNC flow forming lathe designed for cylindrical flow forming of cast wheel rims.

METAL SPINNING

NTR 100/30

Since its establishment in 1885, DENN has manufactured metal spinning machinery. Its models have gradually evolved, from the primitive manual lathes to the current machines operated by computer systems.
