    LSR Molding

    This molded damper incorporates an inserted O-ring that can be made from LSR to allow soft surface compliance for medical devices and other healthcare products.

    Design for Manufacturing (DFM): Building Smarter from the Start

    At ASYST, we believe great products begin long before production starts – they start with designing for manufacturability. DFM is the practice of optimizing product designs to reduce complexity, cost, and risk while ensuring quality and scalability. It is important to consider key principles such as simplified geometry, material selection, standardizing components, aligning tolerances with intent, and designing with the mold in mind.
