Trelleborg Sealing Solutions offers up new digital manufacturing process for LSR parts

Trelleborg Sealing Solutions says it is supporting manufacturers with iCast™ LSR, a new fast and flexible digital manufacturing process for product development and small batch production of Liquid Silicone Rubber (LSR) parts.

Trelleborg’s iCast LSR process, the company says, offers a cost-effective way for manufacturers to develop product variations or try out different design concepts before investing in serial production tools. In addition, the process enables the start of pre-series and series production with small batches, to close the gap between low and high-volume production.

Felix Schädler, Project Manager Innovation & Technology at Trelleborg Sealing Solutions, says: “iCast LSR is an adaptable five-step modular process that utilises digitisation and new manufacturing techniques. It can dramatically cut concept to production time for prototypes from several weeks to a few days for the average part. This helps manufacturers meet the pressures of rapidly moving markets that are demanding faster new product introductions, improvements, and advancements.”

The Trelleborg iCast LSR process starts with the submission of 3D part data and order details. A feasibility study based on artificial intelligence is triggered to confirm if the iCast LSR process is suitable for production of the part. Upon completion of the feasibility study, the part design is analysed, and the individual digital mold layout is created based on 3D data. If necessary, this undergoes mold flow simulation. In a virtual environment, this process identifies the optimum production process for the use of additive manufacturing technologies in order to achieve the best possible quality.

With iCast LSR technology, quick and multiple design iterations of components in standard industrial grade two-component platinum-cured LSR can be made, the company said. These demonstrate the properties and quality levels of high-volume injection molded parts. Currently suitable for production of one to 2,500 parts, Trelleborg’s iCast manufacturing process can be used to produce a wide range of 2D and 3D LSR components including O-Rings, profile seals, diaphragms and custom-molded parts.
