Blowing machines—especially PET bottle blowing and Mold blowing equipment—play a critical role in manufacturing, packaging and related industries. However, due to their high pressures, high temperatures and moving parts, they can present serious hazards if not operated carefully. This article describes essential safety measures for using blowing machines, and also introduces how BOHANG’s factory strength supports safe, reliable equipment.
Before operating a blowing machine, operators should be aware of the main sources of danger:
High pressure: Compressed air or gas used for blowing can cause serious injury if release or rupture occurs.
High temperature: Hot parts (barrels, molds, heating elements) can cause burns.
Moving parts: Clamping units, ejectors, conveyors, Manipulators, etc., can pinch or crush.
Electrical hazards: Incorrect or damaged wiring, improper grounding, or wet environments increase risk of shock.
Material hazards: Some plastics or additives may emit fumes; handling hot plastic may produce splashes or particles.
Ergonomic strain: Poor posture, repetitive motions can result in musculoskeletal injuries.
These are safety features built into the machine or facility to reduce hazard exposure.
Guarding and enclosures: Ensure all moving parts (clamps, rotating shafts, ejectors) are properly shielded. Access panels should be lockable.
Emergency stop mechanisms: Easily accessible emergency stop buttons or bars around the machine. They should cut power, stop motion, and depressurize where possible.
Interlocks: Doors or access points should have safety interlocks so that machine can’t run while open.
Pressure relief valves: For compressed air/gas systems to prevent over‐pressure failures.
Temperature controls & insulation: Maintain safe surface temperatures; insulate hot surfaces where possible.
Ventilation and fume control: Proper exhaust to remove any toxic or irritating fumes produced during heating or melting of plastics.
Noise control: Blowing machines can be loud—enclosures, barriers, or PPE to reduce noise exposure.
These are procedural and training measures to reduce risk.
Training & certification: Operators should be trained on the specific machine, able to recognize hazards and know emergency procedures.
Standard operating procedures (SOPs): Clear instructions for start‐up, operation, shutdown, cleaning, maintenance.
Lockout / tag‐out (LOTO): When cleaning or maintenance is conducted, isolation of energy (electric, pneumatic, hydraulic) must be ensured.
Routine inspections & maintenance: Regular checks for wear & tear (belts, hoses, seals), proper lubrication, calibration of sensors, condition of guards.
Regular safety audits: Verifying that safety equipment (guards, emergency stops, alarms) is functional and used.
Personal protective equipment (PPE): Gloves resistant to heat, safety glasses or face shields, protective clothing, ear protection.
Clear signage: Warnings for hot surfaces, pinch points, required PPE, emergency exits.
Pre‐operation checks: Inspect machine before use—no leaks, guards in place, safety switches functional, correct temperature & pressure settings.
Proper startup: Bring up heating and pressure gradually. Warm up plastic‐melting components to avoid thermal shock.
Monitoring during operation: Watch for unusual noises, vibrations, temperature spikes. Monitor pressure gauges, thermal sensors.
Safe handling of molds and parts: Use tools or manipulators rather than bare hands when moving hot molds.
Shutdown procedures: Cool‐down period, depressurizing, isolating power. After shutdown, ensure no residual pressure or heat remains that may pose risk.
Emergency response: Clear plan for fires, burns, mechanical failure. First aid kits and fire extinguishers should be on site and personnel trained.
Use OEM parts where possible: Ensures compatibility and safety.
Proper lubrication and cooling: Avoid overheating of mechanical parts which could lead to failure.
Calibration of sensors and pressure regulators: Faulty readings can mislead operators regarding safety limits.
Ensure alignment and balance: Vibrations due to misalignment can cause mechanical stress and failure.
Record keeping: Maintenance logs, incident reports to track issues and prevent recurrence.
When you choose equipment from BOHANG, you benefit from:
Modern, well-equipped factory: BOHANG is based in Guangzhou, with a factory that handles research & development, production, installation and after-sales support.
Quality assurance: BOHANG emphasizes reliable manufacturing, precise components, strong control of parts and assembly standards.
Fast delivery and after-sales service: Ensuring that replacements, maintenance, and technical support are rapid, which helps when safety parts need repair or replacement quickly.
Product varieties: BOHANG offers automatic PET Bottle Blowing Machines, semi-automatic systems, manipulators, and molds. Variety allows customers to choose equipment that fits their safety and production needs.
This means purchasing from BOHANG is not just getting a blowing machine—but getting support of safety design, manufacturing integrity, and maintenance capability.
Comply with local manufacturing and workplace safety standards (e.g. OSHA in the US, CE marking in Europe, etc.).
Ensure electrical systems meet national codes.
Ensure pressure vessels or pneumatic systems are certified.
Maintain documentation (manuals, risk assessments, training records).
Scenario: A guard removed for cleaning, machine accidentally started → serious crush injuries. Lesson: Always use lockout/tag‐out; enforce interlocks so machine cannot run unless guard is in place.
Scenario: Overheated mold due to faulty temperature sensor → burn accident. Lesson: Always maintain and calibrate sensors; have backups or failsafe mechanisms.
Safety in blowing machine operation is multi-layered. It requires:
Well-designed machines with engineering safeguards.
Proper procedures, training, and supervision.
Diligent maintenance and prompt repair of safety systems.
Compliance with standards and regulations.
BOHANG’s reliable factory infrastructure, strong quality control and responsive after-sales services make their equipment a good choice for organizations aiming to maintain high safety standards.
