High-flow nesting table

Nesting technology for rational production. With the nesting process, a porous protective panel – usually a thin MDF panel – is held down on the machine table by a vacuum. It provides a large surface for suction and serves to support the workpieces to be processed. Nesting technology allows optimized processing and cutting of panel materials.

  • For formatting nesting cutting plans on the nesting table.
  • Workpieces can be processed with manually positioned suction cups.
  • The HOLZ-HER nesting table has small matrix dimensions – of only 50 mm – to ensure maximum vacuum flux over the entire table surface.

Variable subdivision of standard elements

The Günthner company is a producer of sun protection systems that produce standard products in small series.

[...] The panel materials for the production of wood components are now being processed by Günthner with a complete solution from Holz-Her. In addition to a Tectra 6120 power plate divider and a Dynestic 7516 nesting machine, this system consists of a 5110 storage bin with ETR-300 labeling station, which supplies both dividing machines with plate materials. "We already had a saw and a nesting CNC in front of this combi-system, but they were both over-aged and had to be replaced. The storage and transport of the plates with vacuum lifters were no longer contemporary. Here, we wanted to relieve our employees and bring order to the camp ", reports the managing director. "The separate replacement of the two old machines was not an option. We wanted an overall concept. "

A year ago, Günthner looked at such a concept at another manufacturing company. It was clear right away. So he got to know different manufacturers and invited them to Rottweil to present their design. Finally, the decision to choose Holz-Her is based not only on machine technology but also on a good spatial arrangement of the concept, the regional proximity to the supplier and the conclusive software package. Since the end of May, the plant, which was built parallel to the old machines still working at that time, is in the house. [...]

Exclusive yacht interior with nesting technology

Reference customer Sinnex nesting machine from HOLZ-HER

Sinnex, with headquarters in Swabian Steinheim, specializes in exclusive and highly custom interior furnishings for motor boats and yachts, luxury hotels, private jets, villas and private residences, executive boardrooms and operas and concert halls. Attention to detail, dexterity and exquisite craftsmanship as well as mastery of state-of-the-art technologies are united to form a perfect symbiosis at Sinnex. This results in perfect interaction of demanding technology and superlative craftsmanship, worth appreciating.

“We combine state-of-the-art technology with traditional craftsmanship”, stated Alexander Höfling, Commercial Business Manager at the Sinnex production facilities in Griffen. “With our 120 employees, together with up to 500 specialists from a a network of cooperating companies, we cover all interior finishing work to realize exclusive and exquisite surroundings.” Work accomplished by the company itself as well as it network partners all carries the same common hand. Some of Sinnex’s core competencies are in project management. “In cooperation with many partner companies, each belonging to the best in their field, we frequently handle highly complex interior finishing projects as general contractor.” We use high quality interior finishing materials such as wood, metal, natural stone, glass and textiles, chosen in direct cooperation with the customer and architects. “Our technical equipment and organizational competency provides the base to make it possible”, continued Höfling, “to also allow traditional-working shops offering exclusive craftsmanship to participate in the project work.” This expands capacities tremendously, allowing us to provide exclusive, one-of-a-kind finishing work while always remaining flexible to changes on the market and new trends.

“One of Sinnex’s particular strengths” according to the 46-year-old nautical engineer, “is finishing work on luxury motor boats and yachts, whereby we handle the entire interior finishing spectrum from initial planning to final acceptance of the finished work.”

“To continue to meet the continuously increasing requirements in this high end field of interior finishing, we have upgraded our production line at our production facilities in Körnten to the state-of-the-art this summer,” informed Wolfgang Walzl, Technical Business Manager at Sinnex in Griffen. For example an automatic storage system from Barbaric was installed, and is being used to charge a new CNC nesting machine from HOLZ-HER. Procurement of this combined automated system consisting of a Dynestic 7521 with automatic horizontal storage equipment from Barbaric, was a reaction to the continuously increasing pressure of competition, explained Walzl, who has been active in the company since 2004. The new nesting equipment ensures optimum organization for the entire cutting process frequently involving extremely high quality panel material with sensitive surfaces. “We process materials such as chipboard and plywood panels, aluminum core and foam glass panels as well as even some laminated veneer surfaces”, stated 40-year-old Walzl. “The shaped parts produced here are either used directly in our production or are sent to partner companies in our network.”

Playfully easy implementation - with HOLZ-HER nesting technology

 

“Impressive, exclusive, unique!" - is the motto of the Möbelwerkstatt Schulte Company located in Merzen in Lower Saxony. Whether platform landscapes, shelving systems or wardrobes - this family company with headquarters in the vicinity of Osnabrück has specialized in custom, child-oriented furnishings. This company, specializing in custom-made furniture for young children started production the end of 2011 optimized with nesting technology from HOLZ-HER using a DYNESTIC 7516.

Furniture for “Young Explorers”

 

Children explore their environment by playing, using all their senses. High quality materials and colors are important elements for production of children’s furniture and toys. A mixture of smooth and rough as well as soft and hard surfaces provides suspense, diversity and a wealth of haptic sensation for “little explorers”. The materials used for production include Plexiglas®, multiplex, textile coverings, wood, metal, HPL panels and plastic coated panels as well as linoleum and mirrors.

Minimum cutting loss

 

Children’s furniture is small. Toys, towers and slides, railings, things to climb on with bullseyes, openings and handles - an infinite variety of small parts require formating and drilling to construct a child-oriented play landscape. Naturally the work process needs to be accomplished with as little cutting loss as possible. And this is precisely what is offered by “NestedBased Manufacturing” (NBM) - maximum reduction of cutting losses by ‘nesting’ the workpieces on the vacuum machining table.

Inspiration at the Ligna

 

Personal contacts and technical presentation of HOLZ-HER’s own portfolio quickly provided convincing evidence of HOLZ-HER’s excellent reputation as a contact partner. “After listening to a service technician at the Ligna explain and demonstrate the DYNESTIC, our decision was clear”, declared the senior partner.
Both father and son were amazed particularly by the immense time savings made possible by the nesting machine’s capability of cutting many small parts from one panel in one pass
The equipment was set up and ready for operation within only one week. “It took a lot less time to get started than we thought.” The program and operating instructions were extremely easy to understand and the work processes are well documented”, explained Henning Schulte. The 28-year-old appreciates the DYNESTIC 7516 particularly for its precision technology for detailed processing of parts with complicated shapes

New technology for higher turnover

 

According to their own information, within just 2 years with the DYNESTIC 7516 Möbelwerkstatt Schulte Company successfully completed significantly more that 50 projects with a range all the way to completely furnishing a nursery school room.
The time saved in production with the nesting technology amounted to nearly 30 percent. Heinz Schulte: "The DYNESTIC 7516 makes it a lot easier for my personnel to process large panels by reducing the physical strain. This makes the work a lot more fun for all of us."
