“Block Foaming”
Blocks of flexible, semi-rigid and rigid foam produced by discontinuous processes are used for some specific applications in the insulation, furnishing and car industry sectors. In this case the production lines require metering units that guarantee a very high-output with the capacity to pour large quantities of material in a relatively short time.
The dosing units specifically designed for high outputs cover an output range between 40 and 700 kg/min, For example, they are typically used for the production of:
· rigid low-density blocks for insulation
· insulated “offshore” pipes with compact filled compounds (e.g. with glass micro-spheres)
· rigid medium-density blocks that can be worked with machine tools to produce models
· semi rigid, blocks for headliners
· viscoelastic foams for mattresses and pillows.

We have taken the wishes of our customers into account. By using new construction techniques and materials, we have achieved a lower price level for our tiebarless TVZ series, which makes this premium technology even interesting in the EPS business.
The original TVZ design used a hybrid drive system of electric and hydraulic. At the request of our customers, a hydraulic drive system with separate driving and clamping cylinders is now implemented into the TVZ machines.
This is an example of the customer driven design refinements which have lead to both design advantages and cost savings, helping to offset the surcharge of the tiebarless molding technique.

Low Pressure Metering Machines
The brand new IMPACT series of low pressure machine launched by OMS Group marks a new era in our technology and stems from customers' needs to have a simple, user friendly setting of machine parameters, status displays, pouring times,etc.
In fact, in designing IMPACT, we kept in mind the need to simplify interface with the operator and to minimise maintenance operations.
The FM series of low pressure machine features electro-mechanical control technology and their simplicity and versatility allows the operator a more functional handling of the production cycle.
All our series of low pressure machines are equipped with ULTIMIX series of low pressure mixing heads which incorporate a mechanical mixer offering the possibility of dosing two or more components (i.e.:colours) directly into the mixer chamber. This range of low pressure mixing heads has been designed bearing in mind the need for reliability and ease of maintenance.

Air filters and gaskets
OMS Group manufactures high tech plants for the following sectors:
- original equipment manufacturer for automobiles
- spare parts
Each one of these requires different production typology:
Oval carousel plant
Rotary table plant
Mono-product oval carousel plant for the automotive industry
It is used for large scale production (500 pcs/h).
Steps of production cycle:
- heating and transfer of the mould to the foaming area by a programmed manipulator handled through a computerized unit
- the mould is transferred, along a belt conveyor, to the assembly station
- the upper and lower parts are conveyed to the next station where an operator provides assembles and positions them on to the press.
- the press is conveyed toward the oven where polimerization takes place
- filter demoulding.
Multi-product rotary table plant for spare parts industry
By this system it is possible to produce varied model production since the single presses of the table can carry different types of moulds.
The number of the stations and the polimerization time vary according to the final product characteristics.
Hourly production: 240/360 pcs.

Panels
The application of expanded polyurethane foam has definitively marked a turning point in the industrial and building insulation fields, imposing its technologic validity. It is mainly used for the production of pre-fabricated panels in both discontinuous and continuous process.
Discontinuous Process
This process is adopted to produce panels of different thickness and dimensions. For this production presses able to produce panels up to 14m long and 200mm thickness are being used.
Panels width varies from 0.5m for doors up to 2.50m for refrigerant container.
Both rigid and/or flexible substrata are used, with smooth or grooved profiles according to individual customer's requirements.
Production processes:
- manual side injection system with closed press
- LANCIA automatic injection system with closed press
- automatic injection system with open pour technique
Continuous Process
This process allows a large scale production of different type of panels with flexible or rigid substrata. For industrial production, it is certainly more convenient for both the quality and quantity aspects over the discontinuous process.
The most current foaming systems using c-pentane as an alternative blowing agent are provided with specially designed safety systems to avoid any possible explosion danger.
Production processes:
- PU distribution traverse
- heated pouring platen with view for the suction plant
- double belt conveyor
- high pressure 4 component foaming machine
- metal sheet panels production plant

Refrigerators
Point of reference in the refrigerator and freezer fields, OMS Group has always maintained a close eye on innovative technology, continously updating its production processes to meet the ever increasing demand for prime quality standards, reliability and output, yet not forgetting environmental issues.
Our supply range covers the entire refrigerator production process: from preheat ovens to foaming machines, from cabinets fixtures and jigs to automatic loading and unloading carriers.
OMS Group has been a pioneer in the implementation of new technological applications aimed to manufacture environment-friendly plants for expanded polyurethane production, paying close attention to safety issues: the elimination of any possible explosion hazard and continous monitoring of the dangerous areas by audible and visual alarm systems.
Due to the opening of new flourishing and important markets and the increase of demand, in recent years we have expandend the domestic and industrial refrigerators department and built a new factory site just for this particular sector. Our plants using cyclo-pentane as an alternative blowing agent, cover the entire refrigerator production process: from storage tanks to premixing systems, foaming machines, cabinet fixtures and rotary drums; from safety systems with continuous air recirculation to electrical control and alarm panels.
Thanks to our long acquired experience, we can design and supply plants which fully meet the specific requirements and needs of any end-users through the use of standard parts certified by international quality and safety bodies.

The expansion of the product range by special particle foam materials such as Expandable PolyPropylene (EPP), Expandable PolyEthylene (EPE) or copolymers has also considerably improved the options available to the manufacturers of mouldings to open up new sales opportunities by means of new applications. These particle foam materials make special demands on the machine building industry in terms of an increased closing force for the moulds. Kutz shape moulding machines of the HP-line can be operated with a steaming pressure of 5 up to 7.5 bar.
Mouldings made of EPP are especially suited for impact loads because of their mechanical properties. Therefore they are used more and more in the automotive industry for quite a long time now. These parts are featured by a high energy absorption capacity, a wide temperature range, a good ability to restore the original shape as well as by a simultaneously available recycle ability.
Well known applications such as sun visors and bumpers are nowadays supplemented by knee pads or side impact protection systems as they are used to increase the passengers' safety. Kurtz has accompanied this development permanently or was ahead of it having the matching machine concept for every application available.

When your designs require EMI gaskets that exhibit high attenuation and low closure force, Metex Conductive Fabric gaskets are an ideal choice.
By combining a soft core with conductive fabrics, we have created a gasket that will provide >65 dB attenuation at 1 GHz, and compression loads under 4 lbs. per inch at 25% deflection. Low compression forces allow for lighter, less expensive enclosure designs.
Conductive Fabric gaskets are the ideal gaskets to use with conductive coatings that can be scratched or damaged by other more abrasive gasket materials. The conductive fabrics available include abrasion-resistant copper and nickel.
