The ISO standards for injection machine is ISO 20430.
The ISO 20430 standard specifies in detail the safety requirements during the design, construction,
and use of injection molding machines, including basic requirements such as start-stop, emergency stop function, mechanical protection, etc.
As well as specific safety requirements for the clamping area, clamping structure area,
external motion structure, nozzle area, injection molding area, and discharge area.
In addition, the ISO 20430 standard is based on the European standard EN 201:2009 and combines the current state of the art with existing national and regional standards.
This standard has been adopted by the Chinese national standard GB/T 22530-2022 and implemented as a recommended standard.
Two aspects of ISO standards for injection Moulding machine
- ISO 294 series of standards for injection Moulding machine
- ISO 20430 standards for injection Moulding machine
ISO 294 series of standards
These standards mainly deal with the injection molding process of plastic materials, including the method of determining mold shrinkage.
For example, ISO 294-3:2002 and ISO 294-4:2018 specify the operating conditions of injection molding machines and the method for determining mold shrinkage, respectively.
ISO 20430 standard
This is the world’s first harmonized international safety standard for injection molding machines, based on the European standard EN201:2009.
This standard puts forward comprehensive safety requirements for the design, construction, and use of injection molding machines, and is an important safety specification in the rubber and plastic processing industry.
Specific requirements of the ISO Standard
The ISO 20430:2020 standard is a safety requirement for injection molding machines for plastic and rubber machinery,
and its specific safety requirements include the following aspects:
- Injection device area
- Clamping mechanism area
- Movable guards for hydraulic axes
- Door lock mechanism
- Safety Signs and Command Signs
- Safety PLC
- Waterproofing
Injection device area
The safety requirements for the injection device area have been modified to ensure safety during operation.
Clamping mechanism area
The requirements for the clamping mechanism area or the area behind the moving platen have been adjusted to improve operational safety.
Movable guards for hydraulic axes
Changes have been made to the safety requirements for Type I protection and Type II protection to improve the safety of hydraulic axle operation.
Door lock mechanism
The injection molding machine is equipped with an ISO 20430:2020 compliant door lock that prevents access to the internal area of the machine until all moving parts have come to a complete stop.
Safety Signs and Command Signs
Requirements for safety signs, prohibition signs, and command signs have been added to improve operator understanding and compliance with safety information.
Safety PLC
A safety PLC that complies with international safety standards switches off and controls the power supply based on the input signal from the safety device,
ensuring a high level of reliability.
Waterproofing
Enhanced louver structure vents on the control panel cover reduce the possibility of failure to prevent possible short circuits.
When designing and manufacturing injection molding machines, the requirements of the ISO 20430 standard must be followed.
This includes ensuring that the equipment operates safely under both normal operating and predictable conditions of misuse.
Haichen injection molding machines follow ISO standards
When designing and manufacturing injection molding machines, Haichen follows the requirements of the ISO 20430 standard.
This includes ensuring that equipment operates safely under both normal operating and predictable conditions of misuse.
For example, only fully trained Hichain personnel are allowed to operate or maintain the equipment.
Haichen operators must comply with all safety regulations when operating the equipment,
such as not wearing long hair, loose clothing or jewelry to avoid being caught up in the equipment and causing serious injury.
At the same time, make sure there is a guard around the nozzle to prevent the material from splashing or dripping.
ISO 20430 is the world’s first harmonized international safety standard for injection molding machines.
ISO 20430 provides manufacturers with globally harmonized safety requirements.
