Laser cutting

Advanced laser-cutting technology

PROVAN uses a innovative laser cutting machine to precision-cut customised parts from sheets. Sheet laser cutting is very quick, and carried out with extreme precision and reliability. We perform laser cutting to tolerances of a few tenths of a millimetre.

By using the latest technology in the field of sheet laser cutting, Provan guarantees top quality service. The design of each part can be customised to meet your specific requirements, and can be cut to provide each part with a unique connecting method. The utmost precision and reliability of our laser-cutting machines ensures that no time is lost with positioning the parts.

Fully automated process

Laser-cutting, loading and unloading activities are all fully automated. Once the sheets are cut, the parts are automatically sorted by type and stacked in piles. This means our production runs 24/7, allowing us to offer you the very best delivery times.

Angle folding-bending

Fast, precise and flexible

Provan has 3 CNC Trumpf angle-folding and bending machines in operation, each with a different compression force and therefore suitable for a range of different assignments. Machines from the TruBend Series 5000 combine innovative technology, accuracy and flexibility to bend the most diverse parts.

Our Trumpf machines make sure the entire bending process – from programming, to change-over to actual bending – is highly productive, so our customers can enjoy the following benefits:

  • Trumpf machines are programmed offline and perform a bending simulation that takes into account the actual tools used for chamfering in the real-time bend sequence. As a result, the machine operator is never faced with unexpected surprises, allowing the work to be carried out more rapidly. This makes our lead times much shorter.

  • Trumpf machines operate with a unique angle system that can measure and/or correct the angle in three different places. Consequently, each angle meets our standard of perfection.

  • The three angle-folding and bending machines can handle a range of different tonnages and have different machine options. This gives PROVAN great flexibility to meet the many diverse and specific customer requests.

Punching & pressing

Punching, Nibbling and Pressing

Depending on the product and the customer’s specifications, our punch-nibbling machine is ready to be deployed to suit the job in hand. A combination of cutting and punching tools offer a simple way to provide any product with the required holes. Provan also has a 100 tonne press force hydraulic pressing machine for a variety of pre-treatment duties, such as deep-drawing or pressing.

Punching

Punching is applied to press holes in metal. Punching can be done with a rectangular, circular or random-shaped stamp. The sheet material is placed on a mould of the desired shape, after which a piercing punch punches out the workpiece.

Nibbling

Nibbling is used to remove a specific shape from a full sheet. The continuous up and down movement of a piercing punch very slowly moves the workpiece in the desired direction.

Pressing

Provan has a hydraulic press machine with a press force of 100 tonnes, which can be used for a variety of pre-treatment jobs, such as deep-drawing or pressing. Deep-drawing presses combine a to-and-fro pull and distort movement, which enables the manufacture of products with more complex shapes and large draw ratios.

Advantages
An infallible supplier

From tube, profile and sheet machining to full assembly: PROVAN has the right technology plus the right people!

QRM

Within the world of suppliers, PROVAN distinguishes itself with smaller batches, a wider range and short lead times. PROVAN owes these qualities to a unique production strategy: Quick Response Manufacturing (QRM).
