Improving control systems in plastics processing machinery
Plastics processing machines play a key role in many industries, enabling the precise and efficient production of plastic components. To improve their operation and increase efficiency, modern control systems based on solid-state relays (SSRs) are increasingly being used. Their integration into machines such as injection moulding machines, extruders or extruders brings many benefits.
1. Durability of machines and precise control
SSR relays provide much higher precision and reliability than traditional electromechanical relays. Due to the absence of moving parts, they eliminate the problem of mechanical wear and tear, resulting in longer life and less frequent servicing of equipment and machines. By using standard SSR relays, such as the RSR52, it is possible to control the temperature very accurately, both in zero-coupling and at any time, which is very important in heating processes.

2. Streamlining and reducing production cycle times
SSR relays, such as the three-phase RSR62 , or the single-phase RSR52, operate extremely fast, enabling precise control of dosing or heating processes. Thanks to their ability to switch within milliseconds, they improve production cycle times, which is crucial in high-capacity plants.
3. Noise reduction at the production site
Unlike electromechanical relays, SSR relays operate silently. Reducing noise in the workplace not only improves employee comfort, but also affects overall ergonomics and productivity.
4. Increased safety and protection against surges
SSR relays provide excellent electrical isolation and surge protection. The advanced optical isolation technology used in Relpol's RSR series relays minimises the risk of damage to delicate electronic components. The devices are equipped with surge protection devices such as varistors (MOVs) and high-speed protection diodes (TVSs).
Choosing the right control system
In the case of plastics processing machinery, such as injection moulding machines or extruders, it is essential to use reliable SSR relays, such as the RSR52 and RSR62, which integrate easily into existing control systems. For precise temperature control, the power controllers of the RSR93 series, which are used in annealing furnaces and annealing chambers, among others, are worth considering.
The implementation of SSR relays in the control systems of plastics processing machinery is a step towards modern, efficient and reliable production. The use of Relpol RSR series technology allows higher precision, reduced operating costs and improved working conditions. By choosing advanced control solutions, the efficiency and quality of production in the plastics industry can be significantly improved.
