The DRC 1210 is a dedicated programmable digital controller developed by Klöckner DESMA Elastomertechnik GmbH of Fridingen, Germany, for their rubber and elastomer injection molding machines. Unlike general-purpose PLCs adapted to injection molding, the DRC 1210 was purpose-designed for the specific control loops, timing sequences, and thermal management demands of elastomer processing — where material viscosity, cure kinetics, and mold temperature interact in ways that thermoplastic-oriented controllers do not natively address.

What processing capabilities does the DRC 1210 enable?

The controller manages the complete injection molding cycle for solid silicone (HTV), liquid silicone (LSR), thermoplastic elastomers (TPE), and conventional rubber compounds across DESMA's FIFO (first-in-first-out) C-system injection units. It supports the FlowControl cold runner system, which allows per-nozzle adjustment of injection volume and timing — critical for multi-cavity molds where cavity-to-cavity fill balance directly determines scrap rate and cure time uniformity. With FlowControl, cure times can be reduced by up to 40% compared to fixed-runner systems by dynamically matching material delivery to each cavity's thermal profile.

What is the upgrade path from the DRC 1210?

The DRC 1210 can be retrofitted to DESMA's newer DRC 2020 HT visualization system, which replaces the legacy operator panel with a 19-inch portrait-format haptic touchscreen supporting multi-pump parallel motion and trend-based process visualization. The DRC 2030 TBM represents the latest generation with full IIoT connectivity, cloud-based remote diagnostics, and predictive maintenance algorithms. For production facilities running DRC 1210-equipped presses — including the widely deployed D 956 (250–1,000 kN) and D 968 series machines — the retrofit path preserves the mechanical investment while bringing the control architecture to current-generation capabilities. DESMA's REMOS remote service device is compatible across all DRC generations for manufacturer-supported troubleshooting.
