Horizontal injection molding machines: Common, but often under‑controlled Horizontal injection molding machines are the workhorses of the plastic industry. They handle big‑volume production, multi‑cavity molds, and complex parts for packaging, automotive, and consumer goods. Many of these machines still run on basic or outdated PLCs that: Don’t log alarms properly. Can’t integrate smoothly with robots or conveyors. Limit cycle‑time optimization. By upgrading to a modern Techmation, Inovance, or B& R controller, you can: Tighten cycle times without losing quality. Add better diagnostics so operators spot issues early. Make it easier to connect automation for lights‑out production. Vertical injection molding machines: Space‑saver, but manual‑friendly Vertical machines are a favorite in small workshops and for insert‑molding applications where floor space is tight. They’re often used for: Small parts. Insert molding (metal inserts, bushings, etc.). Multi‑color or two‑shot‑like setups. A lot of these machines still rely on semi‑manual or basic controllers. That means: Operators stay on the machine longer. Part‑to‑part consistency can drop. Changeovers take more time. Upgrading to a modern PLC controller (Techmation, Inovance, or B& R) can: Automate part removal and ejection. Add quick‑change recipes and profiles. Make it easier to run more complex molds with less supervision. Techmation controllers for injection molding: Power plus simplicity If you already work with Techmation (AK‑628, AK‑668, TECH‑1, TECH‑2, iTech-5610, iTech-5620), you know these controllers are built specifically for plastic injection molding. Key features most shops notice after a retrofit: HMI panels with clear screens that show cycle counts, alarms, and temperature graphs. Multiple temperature zones with easy calibration. Servo‑ready I/O and communication options (RS232/RS485) for connecting drives and sensors. Techmation systems are great if you want: A plug‑and‑play upgrade for existing horizontal or vertical machines. A balance between cost and performance without jumping into high‑end industrial automation. Inovance (Innova) controllers: Affordable control, big upgrade Inovance (often seen as Innova in some markets) is a smart choice when you’re upgrading older hydraulic or small electric injection molding machines without a big capex. Benefits engineers and managers love: Lower cost than high‑end industrial PLCs but still much better than vintage controllers. Better diagnostics and alarm logging, so you can track machine health over time. Easy programming for standard injection cycles and simple automation. These controllers work well for: Small to mid‑size horizontal machines. Vertical machines used for insert or low‑volume parts. Factories that want better control without a full B& R‑level investment. B& R controllers: Where precision meets Industry 4.0 For high‑end or multi‑axis injection molding lines, B& R (Bernecker & Rainer) is a top choice. These systems are common on: All‑electric IMMs. Two‑platen and rotary‑platen machines. Multi‑color or multi‑material setups. What sets B& R apart: Tight integration with servo drives, HMI, and SCADA. Real‑time control for micro‑second‑level timing between axes. Support for Industry 4.0 features like data logging, remote monitoring, and cloud‑connected dashboards. If your shop is moving toward smart factories or lights‑out production, B& R controllers give you the foundation to build on. Retrofitting old machines: More cost‑effective than buying new One of the smartest moves we see in the plastic industry is retrofitting existing machines instead of buying new ones. Most horizontal, vertical, and two‑platen injection molding machines can work for years with: A new controller (Techmation, Inovance, or B& R). Updated servo drives or pumps. A fresh HMI interface. Typical retrofit benefits: Faster cycles with the same machine footprint. Fewer rejects thanks to better temperature and pressure control. Easier troubleshooting through clear alarms, logs, and diagnostics. Longer life for the machine by running it in a smoother, more controlled way. How to choose the right controller for your machine Picking the right controller (Techmation vs Inovance vs B& R) depends on: Machine type: Hydraulic, all‑electric, two‑platen, or vertical. Complexity of the mold: Multi‑cavity, multi‑color, or insert‑molded. Budget and automation level: Do you want a simple upgrade or a full Industry 4.0 setup? A few practical questions to ask: What voltages and I/O counts do you need today and in the next 3–5 years? Are you planning robotic cells or conveyors around the machine? Do you want remote monitoring or data logging for traceability? Once you answer these, it becomes easier to say: “Go with Techmation for a solid upgrade.” “Pick Inovance when you want quality control on a budget.” “Choose B& R if you’re building a high‑end, automated line.” Turn your controller upgrade into a real business advantage A smart controller isn’t just a replacement part — it’s a profit‑driver. Better cycle control means less scrap and more parts per hour. Cleaner diagnostics mean less downtime and fewer service calls. Modern systems make it easier to train new operators and integrate automation. If you work with horizontal or vertical injection molding machines and already use Techmation, Inovance, or B& R controllers, the next step is simple: Evaluate your oldest or most unstable machines and plan a controlled retrofit.
