Moulds for fittings
Moulds for new technologies
Product design and development
In order to obtain the most detailed information possible in advance, ifw employs the Moldflow-Insight module. This examines injection situations, analyses pressures and optimises cooling.
The in-mould simulations allow degassing points to be defined as early as the design phase. Simulation of shrinkage and warpage significantly simplifies mould dimensioning. Even core displacements and stresses in the mould during the injection moulding process can be simulated.
Mould breakage and resulting cost-intensive production outages can be avoided in advance with appropriate diagnostics.
Design by means of Moldflow allows initial samples to be produced more quickly and rework to be reduced to a minimum. In turn, this allows mould lead times to be significantly decreased.
Conclusion: The cost-effectiveness of moulds can be improved significantly using the optimum process parameters determined in advance and by adapting cooling to the simulation results.
Components are produced by 3D printing to test their functionality in advance. This allows assembly operations to be verified and simple function tests to be conducted.
In-house technical centre
In our technical centre, moulds are tested and fine-tuned for production. The centre is equipped for this purpose with state-of-the-art injection moulding machines of up to 1300 tonnes. If needs be, we also have access to machines between 40 and 3200 t at our sister company ifw kunststofftechnik GmbH.
ifw offers the opportunity to attend test runs and see moulds being used in production. This allows us to assist customers in maintaining the moulds and making alterations, e.g. other dimensions, on the actual injection moulding machine. We also offer our customers on-site commissioning, wherever in the world that site may be.
After Sales & Service
In order to assure our customers smooth production over the long term, we consider it absolutely essential to provide comprehensive after-sales service. This service is not restricted to ifw moulds. Injection moulds from renowned third-party manufacturers can also be repaired, modified, or completely overhauled.
In the field of wastewater disposal, the advantages of ifw moulds come into their own. With tried-and-tested mould details (some of them patented) and outstanding mould systems, ifw has established a name for itself in the industry as the number one full-range supplier in the field of wastewater.
Modern condensing boiler systems make completely new demands of the exhaust system. Excellent gas tightness alone is not sufficient for these systems. The pipes must also be leak-tight and resistant to condensates, some of which are corrosive.
Due to the low exhaust gas temperatures, drain systems made of plastic are the ideal choice. We supply high-tech moulds, tailor-made for this application area. They are optimised for processing special plastic materials, such as modified flame-retardant PP, PPS and PVDF.
The range of parts includes boiler flue connections, adaptors, elbows, inspection bends, inspection tees, condensate drains, sleeves, roof outlets, chimney and duct covers, spacers, sealing covers and many more.
At the same time, we can also offer you high-quality parts production at ifw kunststofftechnik. In order to ensure compliance with the strict quality standards concerning long-term leak-tightness of fittings, we regularly conduct relevant tests in our in-house test laboratory.
A healthy indoor environment with fresh, oxygen-rich air is of vital importance for personal well-being. At the same time, regulation of the humidity plays a major role in preventing health hazards and damage to the fabric of the building.
Modern water supply systems convey water reliably and losslessly from the source to the application area. An adequate and reliable supply of hot water, both for heating and for sanitary facilities, is also very important.
For the drinking water supply, we only use special plastics approved for direct contact with drinking water, such as polypropylene (PP) and polyethylene (PE).
Particular requirements are made of the material used for hot water supply pipes, as it not only has to comply with strict hygiene standards, but also withstand high temperatures. Consequently, polyphenylsulfone (PPSU) is often used due to its high temperature stability. This however also means special processing requirements for the injection moulding process.
With our long-standing experience and the aid of Moldflow simulations, we can produce optimum designs for the gating system and its geometry without affecting the material, for example with excessive shear. Optionally, hot runners can be integrated into the injection moulds, which ensure efficient material feed and save material, particularly in the case of PE.
On request, ifw also supports production processes with regular inspections, both before and during series production. The material tests include DSC analysis, MFR determination, tensile tests and part tests, such as time to failure under internal pressure. They are conducted in-house in accordance with various standards (e.g. ISO EN 1167, ASTM D1598/99) that form the basis for approvals by ÖVGW (the Austrian Gas and Water Association).
A safe, reliable supply of natural gas is a key factor in economic and municipal development. Consequently, high molecular weight polyethylene (HMWPE) is used for manufacturing gas supply fittings.
The moulds are made for fittings ranging in diameter from 16 to 630 mm and used for socket, butt and electrofusion welding. The range of parts includes elbows, tees, branches, sockets, reducers, end caps, stub ends, connectors, weld saddles and many more.
In addition , the special ifw modular assembly system allows you to manufacture complete article groups in one master mould. The modular design of this mould system leads to a reduction in production costs and to further increases in your production efficiency.
Our extensive experience in mould-making is the ideal basis for meeting your individual requirements.
ifw moulds are used for processing materials such as PVC, PP, PE, ABS, POM, PVDF and PPSU, as well as for filled and fibre-reinforced materials.
