ISO 20430:2020 PDF

Overview

ISO 20430:2020 - Plastics and rubber machines - Injection moulding machines - Safety requirements - specifies the essential safety requirements for the design, construction and safe use of injection moulding machines for plastics and/or rubber. It applies to machines with hydraulic and/or electrical drives for platen movement and addresses significant hazards during the machine life cycle, including reasonably foreseeable misuse (see ISO 12100:2010). The standard excludes certain machine types (for example, manual-only clamping or hydraulic jack operation, injection blow moulding, reaction injection, compression/transfer moulding, and mould or exhaust system design).

Key topics and technical requirements

ISO 20430:2020 organizes safety measures by area and function. Major technical topics include:

• General safety principles and risk reduction measures aligned with ISO 12100.
• Start, stop, restart functions and emergency stop (E‑stop) design and performance.
• Guards and presence-sensing devices, including ESPE (e.g., light curtains), pressure-sensitive mats/floors/edges, and power-operated guards.
• Two‑hand control devices, acknowledging systems and requirements for use in the mould area.
• Mould area safety: closing movements, thermal hazards, whole‑body access, and additional protections for downstroking/upstroking platens.
• Clamping, injection unit, nozzle and ejection areas: mechanical and thermal hazards and requirements for cores/ejectors outside the mould.
• Hydraulic, pneumatic, electrical and hose‑related hazards, plus electromagnetic interference and fluid release protections.
• Noise, fumes, gases, slip/trip hazards, maintenance/adjustment safety and information for use (instruction handbook, marking, warning signs).
• Verification and testing procedures and normative annexes covering protective types, two‑hand devices, proportional valve use, and a noise test code.

Practical applications and who uses this standard

ISO 20430:2020 is used to:

• Guide machine builders and designers in developing compliant injection moulding machines.
• Support safety engineers, risk assessors and compliance officers in evaluating machine safety and preparing instruction handbooks.
• Inform plant managers, maintenance teams and operators about safe operation, guarding, emergency procedures and maintenance practices.
• Assist notified bodies and certification organizations performing conformity assessments and verification tests.
• Help procurement teams specify safety requirements when purchasing injection moulding equipment.
