In plastic processing, accurate temperature control is essential in order to determine the quality of the final product.
SSRs provide a greater degree of process control than electromechanical relays or contactors, because they don’t contain any moving parts and can switch loads very quickly (a low switching frequency limits accuracy).
Solid State Relays and Magnetic Sensors for the Plastic Industry :
With our integrated back to back connected thyristors and TMS² technology (direct bonded copper substrate), celduc relais’ SSRs provide an extremely robust switching solution for plastic processing equipment manufacturers.
Here are some application examples:
Solid State Relays are used for the pre-heating control, barrel heating control and motor control of rollers & automation
SSR are used to control the pre-heating time process of plastic materials and to control mould heating systems
Key products: Two-Phase Solid State Relays
Firstly, with a traditional injection moulding machine, a “preform” is injected inside a cold mould. Then the “preform” is removed from the mould, warmed up again with an infrared lamp, then put inside a mould with a bottle cavity, blown with hot air, then stretched to create a water bottle.
Key products: Analogue Controllers
Solid State Relays are also used to control the temperature inside temperature controllers, granulate dryers and dehumidifying dryers
Key products: 45mm Pitch Three-Phase Solid State Relays
In recycling machines SSRs are used for pre-heating and heating system control as well as for granulate sanitisation system control.
Key products: Single Phase Solid State Relays – okpac range
