Should I choose PLC control system or Push-button control system when puchasing Yongte Plastic Extrusion Machine?
December,07-2025

As professional manufacturer for plastic extrusion machine, Yongte is focusing on machine quality and technology innovation. We equip high quality electric parts for the control system of extrusion machine, such as Innovance servo motor, servo speed controller, ABB inverters, Siemens or Schneider contractors, Siemens programed touch screen system, Omron temperature controller. For adopting the market demands, we have both push-button control system and PLC control system, they are both good quality and customers can choose according to their production needs.

Description of different extruder control system

Push-button control system: 

This is an extruder control system that uses electrical components such as relays and contactors to form control logic through hard-wiring. It was a common control method used in the early days of the plastics machinery industry (before 2000). below is the picture of Yonbte push-button control system for a plastic pipe extrusion line.

PLC control system: 

This is an intelligent automation system centered on a programmable logic controller (PLC). Through software programming, it achieves precise control and monitoring of various process parameters in the extruder, replacing the traditional relay-contactor control system. It is widely used in modern plastic extrusion production lines. below is the picture of Yongte PLC control system for a WPC profile extrusion line

Comparison of Push-button System vs. PLC Control System

ItemPush-button systemPLC control system
Temperature Control AccuracyLow temperature control accuracy (error ±5℃ or higher), unable to achieve precise closed-loop controlHigh temperature control accuracy (±0.1℃), supports PID closed-loop and multi-segment temperature control.
Expandability of adding functionsIt is hard to add functions after the control system is made, adding functions requires extensive hardware modifications and rewiring, so generally we will add one more control cabinet if customer need to add more functions in future.Functions can be expanded through program modification, simply by adding I/O modules.
Maintenance DifficultyTroubleshooting requires point-by-point inspection, relies on professional electrician experience, but if any buttons damage, it is easy to change.

Fault code prompts available, program can be backed up, so the troubleshooting efficiency is high. 

ReliabilityContacts are prone to oxidation and loosening, greatly affected by the environment

 Industrial-grade design, strong anti-interference ability, long mean time between failures (MTBF).

Summary

The Push-button control system for extruder is easy operate and it is suitable for the factory whose engineer is not so professional and whose engineer doesnot like to use computer for the production, so if you will buy a simple extrusion machine for making simple product, then you can consider purchasing the extrusion machine with push-button control system.

The PLC control system for extruders, through a combination of hardware and software, achieves comprehensive intelligent control of the extrusion process. This not only improves product quality and production efficiency but also significantly reduces maintenance costs and downtime. The PLC control system is the core of achieving automated, high-precision production; therefore, if you require a highly automated production line, you should consider purchasing the extrusion machine with push-button control system.

No matter you choose Push-button control system or PLC control system, Yongte team shall provide you high quality machine with good service.
