LSK Lindner manufactures stamped / bent parts and sheet metal components. In the field of metal forming, we accompany our customers from the first idea through project planning and engineering, construction and tool making, prototypes and initial sampling to series production and spare parts supply. In addition to punching / bending technology, CNC sheet metal processing (laser cutting, nibbling and bending) and welding techniques (with robots and manually) are used in production, depending on individual requirements.

We are a medium sized company with many years of experience and expertise in the field of sheet metal processing.

Our specialty is the production of switchboards and special housings in small and large series. In addition, we are a competent partner for special solutions and special designs.

Our performance makes us a reliable partner for many companies in the fields of rail, vehicle and plant construction.


Production

Modern jobs at the highest level

In order to manufacture your products LTH System GmbH Berlin are high quality machine tools for a variety of methods are available that meet the modern standard of a manufacturing company.

It can be processed sheets 3000 mm with a size of 1500 x, there are CNC-controlled bending machines and CNC-controlled guillotine shears ready for further processing.

The laser high pressure cutting allows the oxide-free machining stainless steel to (15 mm) thickness and burr-free machining of aluminum (10mm) and many other materials.

On the hydraulic saw profiles can be cut to 120 mm. The three-roller bending machine, presses, punching machines and other metalworking machines complete the range.

Product treatment

Protection function and finish

For the finishing of the product is directly from us, the surface treatment.

In addition to the in-house wet paint line and the powder plant, which

We are your specialist for bending, stamping and laser technology.

The vision for a new company - according to this principle has already been traded late nineties. In consequence of this was a full-service provider to consistently place customer benefits at the heart of his actions: the door line GmbH.

As an efficient specialist in metal processing, the medium-sized company has now successfully established in the market. Three decades of experience in using the latest CNC machining technology - for the Elementebau up to the facade trade - were in favor of the ideal condition.

On this basis, the bending, stamping and laser technology developed to the core business of the door line. The current focus is the demanding field of stainless steel and aluminum sheet processing. Manufacturers of different industries use the flexible capacity and the excellent service of the door line teams to strengthen their competitive positions.

Whether custom items, prototypes or products: The trimmed on punctuality, precision and top-quality high-tech machine park offers door-line customers in greatest challenges decisive advantages.

Current investment in the future: door line generated design-oriented in-house developments, to position itself as a manufacturer. In addition, the new products offer interesting growth opportunities in other markets. The product range already includes prominent families of future-oriented stainless steel and aluminum.

The extraordinary appearance in the door line "high-tech" look refined both indoor and outdoor areas. Exclusive design desks and shelving systems, PunchART-Pictures, but also individual, made by Default idea - there is always a smart solution and the creativity of door line behind it.
