The essence of RIM technology is the injection of a monomer mixture directly into the production mould, where the mixture subsequently polymerizes under specific conditions.
- RIM – Reactive injection
- RRIM – Reactive injection containing fillers
- SRIM – Structural reactive injection moulding (containing 2D or 3D reinforcements)
The required conditions for this process are the very low viscosity of the injected mass at a lower temperature than the temperature of the mould.
RIM is a technology specifically for low viscosity injected components produced under low injection pressure.
The main advantages of this technology are:
- less investment in moulds and injection units;
- easier filling of complicated and large parts;
- optimization of properties with respect to specific requirements.
RIM technology is optimal for series production ranging from hundreds to tens of thousands of parts.
Technology involving the forming of composite materials reinforced with glass fibres.
SMC technology is used mainly in the automotive industry, but can also be applied in the electrical industry and construction.
Parts produced by vacuum forming can be delivered in the required colour, gloss or matt, smooth or patterned – according to customer requirements. As a rule, parts are no longer painted, but the processed materials can be painted, with a few exceptions.
The technology is most often used for series production ranging from hundreds of pieces per year to tens of thousands of pieces per year.
Combination of spray and foam PU-RIM systems. This combination of technologies enables the production of parts made from different materials in one mould. The carousel semi- automatic arrangement technology is highly productive.
The Promens paintshop is equipped for small and medium series production of visible exterior and interior plastic parts. It meets the high standards of the most demanding customers such as Škoda, Volvo, John Deere and many others.
The painting process involves a development team that monitors all innovations in the field and continuously applies everything that maximizes the quality and environmental friendliness of the process while minimizing costs.
This is an obvious offer from a modern producer of large plastic parts for medium series production.
We use a combination of CAD, CAM systems and 5-axis CNC machining.
We finish parts using CNC machining, for which it is necessary, for example, to remove overflows, inlets, venting, or to cut the part from the preform.
Assembly, gluing and welding
Assembly units for production are delivered Just-in-Time or Just-in-Sequence.
For the integration of supplies, most large exterior plastic parts in Promens Zlín go through assembly operations.
Examples of elements most often mounted in assemblies are lights, curtains, reinforcements, anti-noise elements, washers, grills, metal reinforcements, fixing elements, including the actual connection of individual plastic parts into assemblies (e.g. bonnets).
