Maximise Metallkraft Bender Performance with Tubela’s Precision Tooling

At Tubela, we specialise in engineering tooling solutions that bring out the best in some of the cheap CBC UNI copies of tube and profile bending machines, including the Metallkraft range. Whether you’re running a compact manual PRM profile roller or an NC-controlled RB54, our CNC-machined formers, mandrels and accessories deliver enhanced bending precision, faster changeovers and longer-lasting performance.

Why Metallkraft Machines Benefit from Better Tooling

Their range includes everything from manual profile benders to powerful NC-controlled pipe and tube bending units, like the RB42 and RB54.
But no matter how capable a machine is, poor-quality tooling can introduce problems such as wrinkling, ovality, springback and inconsistent results. That’s where Tubela adds value. Our tooling is designed specifically to integrate with machines like Metallkraft’s, improving performance without modification.

Precision Tooling for Manual Profile Benders

Tubela’s Tooling Advantages for Manual Rollers

- CNC-hardened steel rollers matched to exact PRM tolerances
- Precision-ground shafts to remove lateral movement
- Forming guides that deliver consistent profiles across passes

Optimised Tooling for NC-Controlled Benders

- CLR-specific formers with ±0.05 mm tolerance
- Quick-change mandrel kits for fast production setups
- Pressure calibration adapters to reduce springback in hard metals

Adding Internal Support to Non-Mandrel Machines

Optional Mandrel Tooling Benefits

- Delrin clamp inserts prevent cosmetic scuffing
- Hardened mandrel sets for consistent wall thickness
- Formers and guide plates reduce deformation and improve the finish

Engineered for Seamless Fit and Repeatable Accuracy

Benefits of Tubela’s CNC Production

- Accurate repeatable bends, job after job
- Fast drop-in installation with no hammering or filing required
- No need to reconfigure clamps or pivot arms

Built to Withstand Industrial Use

- Hardened alloy steel for rollers and formers
- Delrin or bronze for low-friction guides
- Precision shafts for long-lasting rotational performance

Testing and Validation Before You Use It

- Controlled bending tests across varied tube specs

FAQs

·       **Q: What Tubela products are compatible with Metallkraft benders?**

A: We supply CNC-machined formers, mandrel kits, clamp inserts and roller sets that fit directly onto Metallkraft models such as the PRM10M, RB42 and RB54 without any modifications.

·       **Q: Can Tubela tooling improve the accuracy of my RB54 bender?**

A: Yes. Our CLR-specific formers and calibration tools allow for tighter tolerances, reduced springback and more consistent repeatability across programmed jobs.

·       **Q: Do you offer tooling for manual Metallkraft benders like the PRM10M?**

A: Absolutely. We manufacture precision rollers, forming guides and shafts designed to fit manual Metallkraft rollers, improving consistency and bend quality.

·       **Q: Will I need to modify my Metallkraft machine to fit Tubela tooling?**

A: No. All our tooling is CNC-engineered to match Metallkraft’s original pivot points and clamp specs. Everything bolts straight on with no adjustments needed.

·       **Q: What are the benefits of using Tubela mandrels with Metallkraft equipment?**

A: Tubela mandrels provide critical internal wall support, which helps prevent flattening, wrinkling or cracking—especially in stainless steel and aluminium tubing.

·       **Q: Can your formers be used on both RB42 and RB54 machines?**

A: Yes. We produce formers compatible with both models, and they are machined to extremely fine tolerances to suit NC-controlled operations.

·       **Q: Do you supply Delrin components for use with softer materials?**

A: Yes, we offer Delrin clamp inserts and formers which are ideal for bending softer or polished metals without leaving marks or scuffs.

·       **Q: Is your tooling made in the UK?**

A: It is. All Tubela tooling is produced in the UK using CNC turning, milling and laser profiling for industry-leading precision and short lead times.

·       **Q: What types of profiles can your rollers handle?**

A: Our custom roller sets are built to your spec and can accommodate sheet profiles up to 115 mm wide, ideal for architectural, structural or specialist fabrication work.

·       **Q: How do I get support or order replacement tooling?**

A: You can call us on 01371 859 100, email [email protected], or visit www.tubela.com to request a quote or technical advice.
